docs/en_us/Backend Deployment Document.md

+# Backend Deployment Document
+
+There are two deployment modes for the backend: 
+
+- 1. automatic deployment  
+- 2. source code compile and then deployment
+
+## 1、Preparations
+
+Download the latest version of the installation package, download address： [gitee download](https://gitee.com/easyscheduler/EasyScheduler/attach_files/) ， download escheduler-backend-x.x.x.tar.gz(back-end referred to as escheduler-backend),escheduler-ui-x.x.x.tar.gz(front-end referred to as escheduler-ui)
+
+
+
+#### Preparations 1: Installation of basic software (self-installation of required items)
+
+ * [Mysql](http://geek.analysys.cn/topic/124) (5.5+) :  Mandatory
+ * [JDK](https://www.oracle.com/technetwork/java/javase/downloads/index.html) (1.8+) :  Mandatory
+ * [ZooKeeper](https://www.jianshu.com/p/de90172ea680)(3.4.6+) ：Mandatory
+ * [Hadoop](https://blog.csdn.net/Evankaka/article/details/51612437)(2.6+) ：Optionally, if you need to use the resource upload function, MapReduce task submission needs to configure Hadoop (uploaded resource files are currently stored on Hdfs)
+ * [Hive](https://staroon.pro/2017/12/09/HiveInstall/)(1.2.1) :   Optional, hive task submission needs to be installed
+ * Spark(1.x,2.x) :  Optional, Spark task submission needs to be installed
+ * PostgreSQL(8.2.15+) : Optional, PostgreSQL PostgreSQL stored procedures need to be installed
+
+```
+ Note: Easy Scheduler itself does not rely on Hadoop, Hive, Spark, PostgreSQL, but only calls their Client to run the corresponding tasks.
+```
+
+#### Preparations 2: Create deployment users
+
+- Deployment users are created on all machines that require deployment scheduling, because the worker service executes jobs in sudo-u {linux-user}, so deployment users need sudo privileges and are confidential.
+
+```Deployment account
+vi /etc/sudoers
+
+# For example, the deployment user is an escheduler account
+escheduler  ALL=(ALL)       NOPASSWD: NOPASSWD: ALL
+
+# And you need to comment out the Default requiretty line
+#Default requiretty
+```
+
+#### Preparations 3: SSH Secret-Free Configuration
+Configure SSH secret-free login on deployment machines and other installation machines. If you want to install easyscheduler on deployment machines, you need to configure native password-free login itself.
+
+
+
+- [Connect the host and other machines SSH](http://geek.analysys.cn/topic/113)
+
+
+#### Preparations 4: database initialization
+
+* Create databases and accounts
+
+    Enter the mysql command line service by following MySQL commands:
+
+    > mysql -h {host} -u {user} -p{password} 
+
+    Then execute the following command to create database and account
+    
+    ```sql 
+    CREATE DATABASE escheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
+    GRANT ALL PRIVILEGES ON escheduler.* TO '{user}'@'%' IDENTIFIED BY '{password}';
+    GRANT ALL PRIVILEGES ON escheduler.* TO '{user}'@'localhost' IDENTIFIED BY '{password}';
+    flush privileges;
+    ```
+
+* Versions 1.0.0 and 1.0.1 create tables and import basic data
+    Instructions：在escheduler-backend/sql/escheduler.sql和quartz.sql
+
+    ```sql
+    mysql -h {host} -u {user} -p{password} -D {db} < escheduler.sql
+    
+    mysql -h {host} -u {user} -p{password} -D {db} < quartz.sql
+    ```
+
+* Version 1.0.2 later (including 1.0.2) creates tables and imports basic data
+    Modify the following attributes in conf/dao/data_source.properties
+
+    ```
+        spring.datasource.url
+        spring.datasource.username
+        spring.datasource.password
+    ```
+    Execute scripts for creating tables and importing basic data
+    ```
+    sh ./script/create_escheduler.sh
+    ```
+
+#### Preparations 5: Modify the deployment directory permissions and operation parameters
+
+Let's first get a general idea of the role of files (folders) in the escheduler-backend directory after decompression.
+
+```directory
+bin : Basic service startup script
+conf : Project Profile
+lib : The project relies on jar packages, including individual module jars and third-party jars
+script :  Cluster Start, Stop and Service Monitor Start and Stop scripts
+sql : The project relies on SQL files
+install.sh :  One-click deployment script
+```
+
+- Modify permissions (please modify the deployUser to the corresponding deployment user) so that the deployment user has operational privileges on the escheduler-backend directory
+
+    `sudo chown -R deployUser:deployUser escheduler-backend`
+
+- Modify the `.escheduler_env.sh` environment variable in the conf/env/directory
+
+- Modify deployment parameters (depending on your server and business situation):
+
+ - Modify the parameters in **install.sh** to replace the values required by your business
+   - MonitorServerState switch variable, added in version 1.0.3, controls whether to start the self-start script (monitor master, worker status, if off-line will start automatically). The default value of "false" means that the self-start script is not started, and if it needs to start, it is changed to "true".
+   - hdfsStartupSate switch variable controls whether to starthdfs
+      The default value of "false" means not to start hdfs
+      If you need to start hdfs instead of "true", you need to create the hdfs root path by yourself, that is, hdfsPath in install.sh.
+
+ - If you use hdfs-related functions, you need to copy**hdfs-site.xml** and **core-site.xml** to the conf directory
+
+
+## 2、Deployment
+Automated deployment is recommended, and experienced partners can use source deployment as well.
+
+### 2.1 Automated Deployment
+
+- Install zookeeper tools
+
+   `pip install kazoo`
+
+- Switch to deployment user, one-click deployment
+
+    `sh install.sh` 
+
+- Use the jps command to see if the service is started (jps comes with Java JDK)
+
+```aidl
+    MasterServer         ----- Master Service
+    WorkerServer         ----- Worker Service
+    LoggerServer         ----- Logger Service
+    ApiApplicationServer ----- API Service
+    AlertServer          ----- Alert Service
+```
+If there are more than five services, the automatic deployment is successful
+
+
+After successful deployment, the log can be viewed and stored in a specified folder.
+
+```log path
+ logs/
+    ├── escheduler-alert-server.log
+    ├── escheduler-master-server.log
+    |—— escheduler-worker-server.log
+    |—— escheduler-api-server.log
+    |—— escheduler-logger-server.log
+```
+
+### 2.2 Compile source code to deploy
+
+After downloading the release version of the source package, unzip it into the root directory
+
+* Execute the compilation command：
+
+```
+ mvn -U clean package assembly:assembly -Dmaven.test.skip=true
+```
+
+* View directory
+
+After normal compilation, target/escheduler-{version}/ is generated in the current directory
+
+
+
+
+
+### 2.3  Start-and-stop services commonly used in systems (for service purposes, please refer to System Architecture Design for details)
+
+* stop all services in the cluster at one click
+  
+   ` sh ./bin/stop_all.sh`
+   
+* one click to open all services in the cluster
+  
+   ` sh ./bin/start_all.sh`
+
+* start and stop Master
+
+```start master
+sh ./bin/escheduler-daemon.sh start master-server
+sh ./bin/escheduler-daemon.sh stop master-server
+```
+
+* start and stop Worker
+
+```start worker
+sh ./bin/escheduler-daemon.sh start worker-server
+sh ./bin/escheduler-daemon.sh stop worker-server
+```
+
+* start and stop Api
+
+```start Api
+sh ./bin/escheduler-daemon.sh start api-server
+sh ./bin/escheduler-daemon.sh stop api-server
+```
+* start and stop Logger
+
+```start Logger
+sh ./bin/escheduler-daemon.sh start logger-server
+sh ./bin/escheduler-daemon.sh stop logger-server
+```
+* start and stop Alert
+
+```start Alert
+sh ./bin/escheduler-daemon.sh start alert-server
+sh ./bin/escheduler-daemon.sh stop alert-server
+```
+
+## 3、Database Upgrade
+Database upgrade is a function added in version 1.0.2. The database can be upgraded automatically by executing the following commands
+
+```upgrade
+sh ./script/upgrade_escheduler.sh
+```
+
+

+
+* Execute the compile command:
+
+```
+ mvn -U clean package assembly:assembly -Dmaven.test.skip=true
+```
+
+* View directory
+
+After normal compilation, it will generate target/escheduler-{version}/ in the current directory.
+
+```
+    bin
+    conf
+    lib
+    script
+    sql
+    install.sh
+```
+
+- Description
+
+```
+bin : basic service startup script

docs/en_us/EasyScheduler-FAQ.md

+## Q: EasyScheduler service introduction and recommended running memory
+
+A: EasyScheduler consists of 5 services, MasterServer, WorkerServer, ApiServer, AlertServer, LoggerServer and UI.
+
+| Service                   | Description                                                  |
+| ------------------------- | ------------------------------------------------------------ |
+| MasterServer              | Mainly responsible for DAG segmentation and task status monitoring |
+| WorkerServer/LoggerServer | Mainly responsible for the submission, execution and update of task status. LoggerServer is used for Rest Api to view logs through RPC |
+| ApiServer                 | Provides the Rest Api service for the UI to call             |
+| AlertServer               | Provide alarm service                                        |
+| UI                        | Front page display                                           |
+
+Note：**Due to the large number of services, it is recommended that the single-machine deployment is preferably 4 cores and 16G or more.**
+
+---
+
+## Q: Why can't an administrator create a project?
+
+A: The administrator is currently "**pure management**". There is no tenant, that is, there is no corresponding user on linux, so there is no execution permission, **so there is no project, resource and data source,** so there is no permission to create. **But there are all viewing permissions**. If you need to create a business operation such as a project, **use the administrator to create a tenant and a normal user, and then use the normal user login to operate**. We will release the administrator's creation and execution permissions in version 1.1.0, and the administrator will have all permissions.
+
+---
+
+## Q: Which mailboxes does the system support?
+
+A: Support most mailboxes, qq, 163, 126, 139, outlook, aliyun, etc. are supported. Support TLS and SSL protocols, optionally configured in alert.properties
+
+---
+
+## Q: What are the common system variable time parameters and how do I use them?
+
+A: Please refer to  https://analysys.github.io/easyscheduler_docs_cn/%E7%B3%BB%E7%BB%9F%E4%BD%BF%E7%94%A8%E6%89%8B%E5%86%8C.html#%E7%B3%BB%E7%BB%9F%E5%8F%82%E6%95%B0
+
+---
+
+## Q: pip install kazoo This installation gives an error. Is it necessary to install?
+
+A: This is the python connection zookeeper needs to use, must be installed
+
+---
+
+## Q: How to specify the machine running task
+
+A: Use **the administrator** to create a Worker group, **specify the Worker group** when the **process definition starts**, or **specify the Worker group on the task node**. If not specified, use Default, **Default is to select one of all the workers in the cluster to use for task submission and execution.**
+
+---
+
+## Q: Priority of the task
+
+A: We also support t**he priority of processes and tasks**. Priority We have five levels of **HIGHEST, HIGH, MEDIUM, LOW and LOWEST**. **You can set the priority between different process instances, or you can set the priority of different task instances in the same process instance.** For details, please refer to the task priority design https://analysys.github.io/easyscheduler_docs_cn/%E7%B3%BB%E7%BB%9F%E6%9E%B6%E6%9E%84%E8%AE%BE%E8%AE%A1.html#%E7%B3%BB%E7%BB%9F%E6%9E%B6%E6%9E%84%E8%AE%BE%E8%AE%A1
+
+----
+
+## Q: Escheduler-grpc gives an error
+
+A: Execute in the root directory: mvn -U clean package assembly:assembly -Dmaven.test.skip=true , then refresh the entire project
+

+
+## Q: Does EasyScheduler support running on windows?
+
+A: In theory, **only the Worker needs to run on Linux**. Other services can run normally on Windows. But it is still recommended to deploy on Linux.
+
+-----
+
+## Q: UI compiles node-sass prompt in linux: Error: EACCESS: permission denied, mkdir xxxx
+
+A: Install **npm install node-sass --unsafe-perm** separately, then **npm install**
+
+---
+
+## Q: UI cannot log in normally.
+
+A: 1, if it is node startup, check whether the .env API_BASE configuration under escheduler-ui is the Api Server service address.
+
+    2, If it is nginx booted and installed via **install-escheduler-ui.sh**, check if the proxy_pass configuration in **/etc/nginx/conf.d/escheduler.conf** is the Api Server service. address
+    
+     3, if the above configuration is correct, then please check if the Api Server service is normal, curl http://192.168.xx.xx:12345/escheduler/users/get-user-info, check the Api Server log, if Prompt cn.escheduler.api.interceptor.LoginHandlerInterceptor:[76] - session info is null, which proves that the Api Server service is normal.
+    
+    4, if there is no problem above, you need to check if **server.context-path and server.port configuration** in **application.properties** is correct
+
+---
+
+## Q: After the process definition is manually started or scheduled, no process instance is generated.
+
+A:   1, first **check whether the MasterServer service exists through jps**, or directly check whether there is a master service in zk from the service monitoring.
+
+​       2,If there is a master service, check **the command status statistics** or whether new records are added in **t_escheduler_error_command**. If it is added, **please check the message field.**
+
+---
+
+## Q : The task status is always in the successful submission status.
+
+A:   1, **first check whether the WorkerServer service exists through jps**, or directly check whether there is a worker service in zk from the service monitoring.
+
+​       2,If the **WorkerServer** service is normal, you need to **check whether the MasterServer puts the task task in the zk queue. You need to check whether the task is blocked in the MasterServer log and the zk queue.**
+
+​       3, if there is no problem above, you need to locate whether the Worker group is specified, but **the machine grouped by the worker is not online**.**
+
+---
+
+## Q: Is there a Docker image and a Dockerfile?
+
+A: Provide Docker image and Dockerfile.
+
+Docker image address: https://hub.docker.com/r/escheduler/escheduler_images
+
+Dockerfile address: https://github.com/qiaozhanwei/escheduler_dockerfile/tree/master/docker_escheduler
+
+------
+
+## Q : Need to pay attention to the problem in install.sh
+
+A:   1, if the replacement variable contains special characters, **use the \ transfer character to transfer**
+
+​       2, installPath="/data1_1T/escheduler", **this directory can not be the same as the install.sh directory currently installed with one click.**
+
+​       3, deployUser = "escheduler", **the deployment user must have sudo privileges**, because the worker is executed by sudo -u tenant sh xxx.command
+
+​       4, monitorServerState = "false", whether the service monitoring script is started, the default is not to start the service monitoring script. **If the service monitoring script is started, the master and worker services are monitored every 5 minutes, and if the machine is down, it will automatically restart.**
+
+​       5, hdfsStartupSate="false", whether to enable HDFS resource upload function. The default is not enabled. **If it is not enabled, the resource center cannot be used.** If enabled, you need to configure the configuration of fs.defaultFS and yarn in conf/common/hadoop/hadoop.properties. If you use namenode HA, you need to copy core-site.xml and hdfs-site.xml to the conf root directory.
+
+​    Note: **The 1.0.x version does not automatically create the hdfs root directory, you need to create it yourself, and you need to deploy the user with hdfs operation permission.**
+
+---
+
+## Q : Process definition and process instance offline exception
+
+A : For **versions prior to 1.0.4**, modify the code under the escheduler-api cn.escheduler.api.quartz package.
+
+```
+public boolean deleteJob(String jobName, String jobGroupName) {
+    lock.writeLock().lock();
+    try {
+      JobKey jobKey = new JobKey(jobName,jobGroupName);
+      if(scheduler.checkExists(jobKey)){
+        logger.info("try to delete job, job name: {}, job group name: {},", jobName, jobGroupName);
+        return scheduler.deleteJob(jobKey);
+      }else {
+        return true;
+      }
+
+    } catch (SchedulerException e) {
+      logger.error(String.format("delete job : %s failed",jobName), e);
+    } finally {
+      lock.writeLock().unlock();
+    }
+    return false;
+  }
+```
+
+---
+
+## Q: Can the tenant created before the HDFS startup use the resource center normally?
+
+A: No. Because the tenant created by HDFS is not started, the tenant directory will not be registered in HDFS. So the last resource will report an error.
+
+## Q: In the multi-master and multi-worker state, the service is lost, how to be fault-tolerant
+
+A: **Note:** **Master monitors Master and Worker services.**
+
+​    1，If the Master service is lost, other Masters will take over the process of the hanged Master and continue to monitor the Worker task status.
+
+​    2，If the Worker service is lost, the Master will monitor that the Worker service is gone. If there is a Yarn task, the Kill Yarn task will be retried.
+
+Please see the fault-tolerant design for details：https://analysys.github.io/easyscheduler_docs_cn/%E7%B3%BB%E7%BB%9F%E6%9E%B6%E6%9E%84%E8%AE%BE%E8%AE%A1.html#%E7%B3%BB%E7%BB%9F%E6%9E%B6%E6%9E%84%E8%AE%BE%E8%AE%A1
+
+---
+
+## Q : Fault tolerance for a machine distributed by Master and Worker
+
+A: The 1.0.3 version only implements the fault tolerance of the Master startup process, and does not take the Worker Fault Tolerance. That is to say, if the Worker hangs, no Master exists. There will be problems with this process. We will add Master and Worker startup fault tolerance in version **1.1.0** to fix this problem. If you want to manually modify this problem, you need to **modify the running task for the running worker task that is running the process across the restart and has been dropped. The running process is set to the failed state across the restart**. Then resume the process from the failed node.
+
+---
+
+## Q : Timing is easy to set to execute every second
+
+A : Note when setting the timing. If the first digit (* * * * * ? *) is set to *, it means execution every second. **We will add a list of recently scheduled times in version 1.1.0.** You can see the last 5 running times online at http://cron.qqe2.com/
+
+
+
+## Q: Is there a valid time range for timing?
+
+A: Yes, **if the timing start and end time is the same time, then this timing will be invalid timing. If the end time of the start and end time is smaller than the current time, it is very likely that the timing will be automatically deleted.**
+
+
+
+## Q : There are several implementations of task dependencies
+
+A：	1, the task dependency between **DAG**, is **from the zero degree** of the DAG segmentation
+
+​	2, there are **task dependent nodes**, you can achieve cross-process tasks or process dependencies, please refer to the (DEPENDENT) node：https://analysys.github.io/easyscheduler_docs_cn/%E7%B3%BB%E7%BB%9F%E4%BD%BF%E7%94%A8%E6%89%8B%E5%86%8C.html#%E4%BB%BB%E5%8A%A1%E8%8A%82%E7%82%B9%E7%B1%BB%E5%9E%8B%E5%92%8C%E5%8F%82%E6%95%B0%E8%AE%BE%E7%BD%AE
+
+​	Note: **Cross-project processes or task dependencies are not supported**
+
+## Q: There are several ways to start the process definition.
+
+A:   1, in **the process definition list**, click the **Start** button.
+
+​       2, **the process definition list adds a timer**, scheduling start process definition.
+
+​       3, process definition **view or edit** the DAG page, any **task node right click** Start process definition.
+
+​       4, you can define DAG editing for the process, set the running flag of some tasks to **prohibit running**, when the process definition is started, the connection of the node will be removed from the DAG.
+
+
+
+## Q : Python task setting Python version
+
+A：  1，**for the version after 1.0.3** only need to modify PYTHON_HOME in conf/env/.escheduler_env.sh
+
+```
+export PYTHON_HOME=/bin/python
+```
+
+Note: This is **PYTHON_HOME** , which is the absolute path of the python command, not the simple PYTHON_HOME. Also note that when exporting the PATH, you need to directly
+
+```
+export PATH=$HADOOP_HOME/bin:$SPARK_HOME1/bin:$SPARK_HOME2/bin:$PYTHON_HOME:$JAVA_HOME/bin:$HIVE_HOME/bin:$PATH
+```
+
+​	2，For versions prior to 1.0.3, the Python task only supports the Python version of the system. It does not support specifying the Python version.
+
+## Q：Worker Task will generate a child process through sudo -u tenant sh xxx.command, will kill when kill
+
+A：  We will add the kill task in 1.0.4 and kill all the various child processes generated by the task.
+
+
+
+## Q ： How to use the queue in EasyScheduler, what does the user queue and tenant queue mean?
+
+A ： The queue in the EasyScheduler can be configured on the user or the tenant. **The priority of the queue specified by the user is higher than the priority of the tenant queue.** For example, to specify a queue for an MR task, the queue is specified by mapreduce.job.queuename.
+
+Note: When using the above method to specify the queue, the MR uses the following methods:
+
+```
+	Configuration conf = new Configuration();
+        GenericOptionsParser optionParser = new GenericOptionsParser(conf, args);
+        String[] remainingArgs = optionParser.getRemainingArgs();
+```
+
+
+
+If it is a Spark task --queue mode specifies the queue
+
+
+
+## Q : Master or Worker reports the following alarm
+
+<p align="center">
+   <img src="https://analysys.github.io/easyscheduler_docs_cn/images/master_worker_lack_res.png" width="60%" />
+ </p>
+
+
+
+A ： Change the value of master.properties **master.reserved.memory** under conf to a smaller value, say 0.1 or the value of worker.properties **worker.reserved.memory** is a smaller value, say 0.1
+
+## Q: The hive version is 1.1.0+cdh5.15.0, and the SQL hive task connection is reported incorrectly.
+
+<p align="center">
+   <img src="https://analysys.github.io/easyscheduler_docs_cn/images/cdh_hive_error.png" width="60%" />
+ </p>
+
+
+
+A ： Will hive pom
+
+```
+<dependency>
+    <groupId>org.apache.hive</groupId>
+    <artifactId>hive-jdbc</artifactId>
+    <version>2.1.0</version>
+</dependency>
+```
+
+change into
+
+```

+### Development environment
+
+- #### Node installation
+Node package download (note version 8.9.4) `https://nodejs.org/download/release/v8.9.4/` 
+
+
+- #### Front-end project construction
+Use the command line mode `cd`  enter the `escheduler-ui` project directory and execute `npm install` to pull the project dependency package.
+
+> If `npm install` is very slow
+
+> You can enter the Taobao image command line to enter `npm install -g cnpm --registry=https://registry.npm.taobao.org`
+
+> Run `cnpm install` 
+
+
+- Create a new `.env`  file or the interface that interacts with the backend
+
+Create a new` .env` file in the `escheduler-ui `directory, add the ip address and port of the backend service to the file, and use it to interact with the backend. The contents of the` .env` file are as follows:
+```
+# Proxy interface address (modified by yourself)
+API_BASE = http://192.168.xx.xx:12345
+
+# If you need to access the project with ip, you can remove the "#" (example)
+#DEV_HOST = 192.168.xx.xx
+```
+
+> #####  ! ! ! Special attention here. If the project reports a "node-sass error" error while pulling the dependency package, execute the following command again after execution.
+```
+npm install node-sass --unsafe-perm //单独安装node-sass依赖
+```
+
+- #### Development environment operation
+- `npm start` project development environment (after startup address http://localhost:8888/#/)
+
+
+#### Front-end project release
+
+- `npm run build` project packaging (after packaging, the root directory will create a folder called dist for publishing Nginx online)

+
+## specification
+## Vue specification
+##### 1.Component name
+The component is named multiple words and is connected with a wire (-) to avoid conflicts with HTML tags and a clearer structure.
+```
+// positive example
+export default {
+    name: 'page-article-item'
+}
+```
+
+##### 2.Component files
+The internal common component of the `src/js/module/components` project writes the folder name with the same name as the file name. The subcomponents and util tools that are split inside the common component are placed in the internal `_source` folder of the component.
+```
+└── components
+    ├── header
+        ├── header.vue
+        └── _source
+            └── nav.vue
+            └── util.js
+    ├── conditions
+        ├── conditions.vue
+        └── _source
+            └── serach.vue
+            └── util.js
+```
+
+##### 3.Prop
+When you define Prop, you should always name it in camel format (camelCase) and use the connection line (-) when assigning values to the parent component.This follows the characteristics of each language, because it is case-insensitive in HTML tags, and the use of links is more friendly; in JavaScript, the more natural is the hump name.
+
+```
+// Vue
+props: {
+    articleStatus: Boolean
+}
+// HTML
+<article-item :article-status="true"></article-item>
+```
+
+The definition of Prop should specify its type, defaults, and validation as much as possible.
+
+Example：
+
+```
+props: {
+    attrM: Number,
+    attrA: {
+        type: String,
+        required: true
+    },
+    attrZ: {
+        type: Object,
+        //  The default value of the array/object should be returned by a factory function
+        default: function () {
+            return {
+                msg: 'achieve you and me'
+            }
+        }
+    },
+    attrE: {
+        type: String,
+        validator: function (v) {
+            return !(['success', 'fail'].indexOf(v) === -1) 
+        }
+    }
+}
+```
+
+##### 4.v-for
+When performing v-for traversal, you should always bring a key value to make rendering more efficient when updating the DOM.
+```
+<ul>
+    <li v-for="item in list" :key="item.id">
+        {{ item.title }}
+    </li>
+</ul>
+```
+
+v-for should be avoided on the same element as v-if (`for example: <li>`) because v-for has a higher priority than v-if. To avoid invalid calculations and rendering, you should try to use v-if Put it on top of the container's parent element.
+```
+<ul v-if="showList">
+    <li v-for="item in list" :key="item.id">
+        {{ item.title }}
+    </li>
+</ul>
+```
+
+##### 5.v-if / v-else-if / v-else
+If the elements in the same set of v-if logic control are logically identical, Vue reuses the same part for more efficient element switching, `such as: value`. In order to avoid the unreasonable effect of multiplexing, you should add key to the same element for identification.
+```
+<div v-if="hasData" key="mazey-data">
+    <span>{{ mazeyData }}</span>
+</div>
+<div v-else key="mazey-none">
+    <span>no data</span>
+</div>
+```
+
+##### 6.Instruction abbreviation
+In order to unify the specification, the instruction abbreviation is always used. Using `v-bind`, `v-on` is not bad. Here is only a unified specification.
+```
+<input :value="mazeyUser" @click="verifyUser">
+```
+
+##### 7.Top-level element order of single file components
+Styles are packaged in a file, all the styles defined in a single vue file, the same name in other files will also take effect. All will have a top class name before creating a component.
+Note: The sass plugin has been added to the project, and the sas syntax can be written directly in a single vue file.
+For uniformity and ease of reading, they should be placed in the order of  `<template>`、`<script>`、`<style>`.
+
+```
+<template>
+  <div class="test-model">
+    test
+  </div>
+</template>
+<script>
+  export default {
+    name: "test",
+    data() {
+      return {}
+    },
+    props: {},
+    methods: {},
+    watch: {},
+    beforeCreate() {
+    },
+    created() {
+    },
+    beforeMount() {
+    },
+    mounted() {
+    },
+    beforeUpdate() {
+    },
+    updated() {
+    },
+    beforeDestroy() {
+    },
+    destroyed() {
+    },
+    computed: {},
+    components: {},
+  }
+</script>
+
+<style lang="scss" rel="stylesheet/scss">
+  .test-model {
+
+  }
+</style>
+
+```
+
+
+## JavaScript specification
+
+##### 1.var / let / const
+It is recommended to no longer use var, but use let / const, prefer const. The use of any variable must be declared in advance, except that the function defined by function can be placed anywhere.
+
+##### 2.quotes
+```
+const foo = 'after division'
+const bar = `${foo}，ront-end engineer`
+```
+
+##### 3.function
+Anonymous functions use the arrow function uniformly. When multiple parameters/return values are used, the object's structure assignment is used first.
+```
+function getPersonInfo ({name, sex}) {
+    // ...
+    return {name, gender}
+}
+```
+The function name is uniformly named with a camel name. The beginning of the capital letter is a constructor. The lowercase letters start with ordinary functions, and the new operator should not be used to operate ordinary functions.
+
+##### 4.object
+```
+const foo = {a: 0, b: 1}
+const bar = JSON.parse(JSON.stringify(foo))
+
+const foo = {a: 0, b: 1}
+const bar = {...foo, c: 2}
+
+const foo = {a: 3}
+Object.assign(foo, {b: 4})
+
+const myMap = new Map([])
+for (let [key, value] of myMap.entries()) {
+    // ...
+}
+```
+
+##### 5.module
+Unified management of project modules using import / export.
+```
+// lib.js
+export default {}
+
+// app.js
+import app from './lib'
+```
+
+Import is placed at the top of the file.
+
+If the module has only one output value, use `export default`，otherwise no.
+
+## HTML / CSS
+
+##### 1.Label
+
+Do not write the type attribute when referencing external CSS or JavaScript. The HTML5 default type is the text/css and text/javascript properties, so there is no need to specify them.
+```
+<link rel="stylesheet" href="//www.test.com/css/test.css">
+<script src="//www.test.com/js/test.js"></script>
+```
+
+##### 2.Naming
+The naming of Class and ID should be semantic, and you can see what you are doing by looking at the name; multiple words are connected by a link.
+```
+// positive example
+.test-header{
+    font-size: 20px;
+}
+```
+
+##### 3.Attribute abbreviation
+CSS attributes use abbreviations as much as possible to improve the efficiency and ease of understanding of the code.
+
+```
+// counter example
+border-width: 1px;
+border-style: solid;
+border-color: #ccc;
+
+// positive example
+border: 1px solid #ccc;
+```
+
+##### 4.Document type
+
+The HTML5 standard should always be used.
+
+```
+<!DOCTYPE html>
+```
+
+##### 5.Notes
+A block comment should be written to a module file.
+```
+/**
+* @module mazey/api
+* @author Mazey <mazey@mazey.net>
+* @description test.
+* */
+```
+
+
+## interface
+
+##### All interfaces are returned as Promise 
+Note that non-zero is wrong for catching catch
+
+```
+const test = () => {
+  return new Promise((resolve, reject) => {
+    resolve({
+      a:1
+    })
+  })
+}
+
+// transfer
+test.then(res => {
+  console.log(res)
+  // {a:1}
+})
+```
+
+Normal return
+```
+{
+  code:0,
+  data:{}
+  msg:'success'
+}
+```
+
+错误返回
+```
+{
+  code:10000, 
+  data:{}
+  msg:'failed'
+}
+```

+
+## Extended development
+
+##### 1.Add node
+
+(1) First place the icon icon of the node in the `src/js/conf/home/pages/dag/img `folder, and note the English name of the node defined by the `toolbar_${in the background. For example: SHELL}.png`
+
+(2)  Find the `tasksType` object in `src/js/conf/home/pages/dag/_source/config.js` and add it to it.
+```
+'DEPENDENT': {  //  The background definition node type English name is used as the key value
+  desc: 'DEPENDENT',  // tooltip desc
+  color: '#2FBFD8'  // The color represented is mainly used for tree and gantt
+}
+```
+
+(3)  Add a `${node type (lowercase)}`.vue file in `src/js/conf/home/pages/dag/_source/formModel/tasks`. The contents of the components related to the current node are written here. Must belong to a node component must have a function _verification () After the verification is successful, the relevant data of the current component is thrown to the parent component.
+```
+/**
+ * Verification
+*/
+  _verification () {
+    // datasource subcomponent verification
+    if (!this.$refs.refDs._verifDatasource()) {
+      return false
+    }
+
+    // verification function
+    if (!this.method) {
+      this.$message.warning(`${i18n.$t('Please enter method')}`)
+      return false
+    }
+
+    // localParams subcomponent validation
+    if (!this.$refs.refLocalParams._verifProp()) {
+      return false
+    }
+    // store
+    this.$emit('on-params', {
+      type: this.type,
+      datasource: this.datasource,
+      method: this.method,
+      localParams: this.localParams
+    })
+    return true
+  }
+```
+
+(4) Common components used inside the node component are under` _source`, and `commcon.js` is used to configure public data.
+
+##### 2.Increase the status type
+
+(1) Find the `tasksState` object in `src/js/conf/home/pages/dag/_source/config.js` and add it to it.
+
+```
+ 'WAITTING_DEPEND': {  // 'WAITTING_DEPEND': {  //后端定义状态类型 前端用作key值
+  id: 11,  // front-end definition id is used as a sort
+  desc: `${i18n.$t('waiting for dependency')}`,  // tooltip desc
+  color: '#5101be',  // The color represented is mainly used for tree and gantt
+  icoUnicode: '&#xe68c;',  // font icon
+  isSpin: false  // whether to rotate (requires code judgment)
+}
+```
+
+##### 3.Add the action bar tool
+(1)  Find the `toolOper` object in `src/js/conf/home/pages/dag/_source/config.js` and add it to it.
+```
+{
+  code: 'pointer',  // tool identifier
+  icon: '&#xe781;',  // tool icon
+  disable: disable,  // disable
+  desc: `${i18n.$t('Drag node and selected item')}`  // tooltip desc
+}
+```
+
+(2) Tool classes are returned as a constructor  `src/js/conf/home/pages/dag/_source/plugIn`
+
+`downChart.js`  =>  dag image download processing
+
+`dragZoom.js`  =>  mouse zoom effect processing
+
+`jsPlumbHandle.js`  =>  drag and drop line processing
+
+`util.js`  =>   belongs to the `plugIn` tool class
+
+
+The operation is handled in the `src/js/conf/home/pages/dag/_source/dag.js` => `toolbarEvent` event.
+
+
+##### 3.Add a routing page
+
+(1) First add a routing address`src/js/conf/home/router/index.js` in route management
+```
+routing address{
+  path: '/test',  // routing address
+  name: 'test',  // alias
+  component: resolve => require(['../pages/test/index'], resolve),  // route corresponding component entry file
+  meta: {
+    title: `${i18n.$t('test')} - EasyScheduler`  // title display
+  }
+},
+```
+
+(2)Create a `test` folder in `src/js/conf/home/pages` and create an `index.vue `entry file in the folder.
+
+    This will give you direct access to`http://localhost:8888/#/test`
+
+
+##### 4.Increase the preset mailbox
+
+Find the `src/lib/localData/email.js` startup and timed email address input to automatically pull down the match.
+```
+export default ["test@analysys.com.cn","test1@analysys.com.cn","test3@analysys.com.cn"]
+```
+
+##### 5.Authority management and disabled state processing
+
+The permission gives the userType according to the backUser interface `getUserInfo` interface: `"ADMIN_USER/GENERAL_USER" `permission to control whether the page operation button is `disabled`.
+
+specific operation：`src/js/module/permissions/index.js`
+
+disabled processing：`src/js/module/mixin/disabledState.js`
+
