+# Atomic Service
+
+## Pre-loading by HAP Type
+
+### HAP File Implementation
+
+To speed up the initial startup of an atomic service, you can configure it to load on demand with the use of HAP files. HAP files of an atomic service are classified as entry-type or feature-type. The entry-type HAP file contains the page code and related resources required for starting up the atomic service. The feature-type HAP files contain the rest of the code and resources. To start the atomic service, the user only needs to download and install the entry-type HAP file, which minimizes the time for downloading the atomic service.
+
+#### How to Use
+
+You create HAP files of an atomic service by creating an atomic service project in DevEco Studio. The basic project directory structure is as follows:
+
+```
+├── AppScope
+| ├── resources
+| └── app.json5
+├── entry
+| └── src/main
+| ├── ets
+| ├── resources
+| └── module.json5
+├── feature
+| └── src/main
+| ├── ets
+| ├── resources
+| └── module.json5
+├── library
+| └── src/main
+| ├── ets
+| ├── resources
+| └── module.json5
+├── node_modules
+```
+
+Note that you must set the **bundleType** field to **atomicService** in the [app.json5](app-configuration-file.md) file, which is located in the **AppScope** folder. The following is an example of the file content:
+
+```json
+{
+ "app": {
+ "bundleName": "com.example.hmservice",
+ "bundleType":"atomicService",
+ "vendor": "example",
+ "versionCode": 1000000,
+ "versionName": "1.0.0",
+ "icon": "$media:app_icon",
+ "label": "$string:app_name",
+ "distributedNotificationEnabled": true,
+ "targetAPIVersion": 9
+ }
+}
+```
+
+For details about HAP files, see [Multi-HAP Design Objectives](multi-hap-objective.md).
+
+#### Restrictions
+
+1. The **installationFree** field must be set to **true** in each module-specific configuration file [module.json5](module-configuration-file.md) file.
+
+2. When packaging an atomic service, comply with the following size rules:
+
+- The total size of HAP files cannot exceed 10 MB.
+
+- The size of a HAP file itself and all its dependent [HSP](in-app-hsp.md) cannot exceed 2 MB.
+
+
+### Pre-loading Implementation
+
+You can configure the system to automatically pre-download required modules when the atomic service enters a module, thereby speeding up module access.
+
+Currently, pre-loading can be implemented only through configuration, not by invoking APIs.
+
+#### How to Use
+
+Pre-loading is triggered after the first frame of the newly accessed module is rendered. You can configure what to pre-load for a module, by setting the **preloads** field under **atomicService** in the [module.json5](module-configuration-file.md) file of the module. The following is an example of the **module.json5** file of the **entry** module, saved in **entry/src/main**:
+
+```json
+{
+ "module": {
+ "name": "entry",
+ "type": "entry",
+ "srcEntrance": "./ets/Application/MyAbilityStage.ts",
+ "description": "$string:entry_desc",
+ "mainElement": "MainAbility",
+ "deviceTypes": [
+ "default",
+ "tablet"
+ ],
+ "deliveryWithInstall": true,
+ "installationFree": true,
+ "pages": "$profile:main_pages",
+ "atomicService": {
+ "preloads": [
+ {
+ "moduleName": "feature"
+ }
+ ]
+ },
+ "abilities": [
+ {
+ "name": "MainAbility",
+ "srcEntrance": "./ets/MainAbility/MainAbility.ts",
+ "description": "$string:MainAbility_desc",
+ "icon": "$media:icon",
+ "label": "$string:MainAbility_label",
+ "startWindowIcon": "$media:icon",
+ "startWindowBackground": "$color:white",
+ "visible": true,
+ "skills": [
+ {
+ "entities": [
+ "entity.system.home"
+ ],
+ "actions": [
+ "action.system.home"
+ ]
+ }
+ ]
+ }
+ ]
+ }
+}
+```
+
+In this example, the system automatically pre-loads the **feature** module after the first frame of the **entry** module is rendered.
+
+#### Restrictions
+
+[moduleType](../reference/apis/js-apis-bundleManager.md#moduletype) corresponding to moduleName in the **preloads** list cannot be entry.
+
+## Using Dynamic Shared Packages in Atomic Services
+
+A [Harmony Shared Package (HSP)](shared-guide.md) is a dynamic shared package for sharing code, C++ libraries, resources, and configuration files among modules.
+For details about how to use the HSP within an atomic service, see [In-Application HSP Development](in-app-hsp.md).
+
+#### How to Use
+
+Assume that the project directory structure is as follows:
+```
+├── AppScope
+| ├── resources
+| └── app.json5
+├── entry
+| └── src/main
+| ├── ets
+| ├── entryAbility
+| └── pages
+| └── Index.ets
+| ├── resources
+| └── module.json5
+├── feature
+| └── src/main
+| ├── ets
+| ├── resources
+| └── module.json5
+├── library
+| └── src/main
+| ├── ets
+| └── pages
+| └── menu.ets
+| ├── resources
+| └── module.json5
+├── node_modules
+```
+
+If you want to add a button in the **entry** module to jump to the menu page (**library/src/main/ets/pages/menu.ets**) in the **library** module, you can write the following code in the **entry/src/main/ets/MainAbility/Index.ets** file of the **entry** module:
+
+```ts
+import router from '@ohos.router';
+
+@Entry
+@Component
+struct Index {
+ @State message: string = 'Hello World'
+
+ build() {
+ Row() {
+ Column() {
+ Text(this.message)
+ .fontSize(50)
+ .fontWeight(FontWeight.Bold)
+ // Add a button to respond to user clicks.
+ Button() {
+ Text('click to menu')
+ .fontSize(30)
+ .fontWeight(FontWeight.Bold)
+ }
+ .type(ButtonType.Capsule)
+ .margin({
+ top: 20
+ })
+ .backgroundColor('#0D9FFB')
+ .width('40%')
+ .height('5%')
+ // Bind click events.
+ .onClick(() => {
+ router.pushUrl({
+ url: '@bundle:com.example.hmservice/library/ets/pages/menu'
+ }).then(() => {
+ console.log("push page success");
+ }).catch(err => {
+ console.error(`pushUrl failed, code is ${err.code}, message is ${err.message}`);
+ })
+ }
+ .width('100%')
+ }
+ .height('100%')
+ }
+}
+```
+
+The input parameter **url** of the **router.pushUrl** API is as follows:
+```ets
+'@bundle:com.example.hmservice/library/ets/pages/menu'
+```
+The **url** content template is as follows:
+```ets
+'@bundle:bundle name/module name/path/page file name (without the extension .ets)'
+```

-When only **scheme** or a combination of **scheme** and **host** or **scheme**, **host**, and **port** are configured in the configuration file, the configuration is successful if a URI prefixed with the configuration file is passed in.
-
- * The query enhancement involves the following APIs:
- [@ohos.bundle.bundleManager](../reference/apis/js-apis-bundleManager.md#bundlemanagerqueryabilityinfo)
- 1. function queryAbilityInfo(want: Want, abilityFlags: number, callback: AsyncCallback>): void;
- 2. function queryAbilityInfo(want: Want, abilityFlags: number, userId: number, callback: AsyncCallback>): void;
- 3. function queryAbilityInfo(want: Want, abilityFlags: number, userId?: number): Promise>;
- * Configuration requirements
- abilities -> skills -> uris object
- Configuration 1: only **scheme = 'http'**
- Configuration 2: only **(scheme = 'http') + (host = 'www.example.com')**
- Configuration 3: only **(scheme = 'http') + (host = 'www.example.com') + (port = '8080')**
- * Prefix match
- If the value of **uri** under [want](../application-models/want-overview.md) is obtained by calling the **queryAbilityInfo** API:
- 1. uri = 'https://': No matches
- 2. uri = 'http://': Matches configuration 1
- 3. uri = 'https://www.example.com': No matches
- 4. uri = 'https://www.exa.com': No matches
- 5. uri = 'http://www.exa.com': Matches configuration 1
- 6. uri = 'http://www.example.com': Matches configuration 1 and configuration 2
- 7. uri = 'https://www.example.com:8080': No matches
- 8. uri = 'http://www.exampleaa.com:8080': Matches configuration 1
- 9. uri = 'http://www.example.com:9180': Matches configuration 1 and configuration 2
- 10. uri = 'http://www.example.com:8080': Matches configuration 1, configuration 2, and configuration 3
- 11. uri = 'https://www.example.com:9180/query/student/name' : No matches
- 12. uri = 'http://www.exampleap.com:8080/query/student/name': Matches configuration 1
- 13. uri = 'http://www.example.com:9180/query/student/name': Matches configuration 1 and configuration 2
- 14. uri = 'http://www.example.com:8080/query/student/name': Matches configuration 1, configuration 2, and configuration 3

# Multi-HAP Design Objectives
-- Modular management: A well-designed application is generally managed in a modular manner, where modules are loosely coupled. In light of this, the multi-HAP mechanism is designed, allowing you to divide services into multiple modules and store each module in an independent HAP file. For example, If you are developing a payment application and its home screen consists of multiple modules, such as the scan, pay, messaging, and finance modules, you can implement the logic of the home screen for managing other modules in the entry-type HAP file, and implement specific modules in feature-type HAP files. The feature-type HAP files are independent. You can develop and test each of them separately, and then integrate them with the entry-type HAP file.
+- Modular management: A well-designed application is generally managed in a modular manner, where modules are loosely coupled. In light of this, the multi-HAP mechanism is designed, allowing you to divide services into multiple modules and store each module in an independent HAP file. For example, if you are developing a payment application whose home screen consists of multiple modules, such as the scan, pay, messaging, and finance modules, you can implement the HAP files as follows: (1) In the entry-type HAP file, implement the home screen logic for managing modules; (2) in feature-type HAP files, implement specific modules. The feature-type HAP files are independent of each other. You can develop and test each of them separately, and then integrate them with the entry-type HAP file.
-- Flexible deployment: You can combine multiple HAP files and deploy them on different devices. Assume that an application contains one entry-type HAP file (**Entry.hap**) and two feature-type HAP files (**Feature1.hap** and **Feature2.hap**). The **Entry.hap** file can be deployed on device A and device B, the **Feature1.hap** file can be deployed only on device A, and the **Feature2.hap** can be deployed only on device B. In this way, you can easily combine the **Entry.hap** and **Feature1.hap** files and deploy them on device A, and combine the **Entry.hap** and **Feature2.hap** files and deploy them on device B.
+- Flexible deployment: You can flexibly combine HAP files for device-specific deployment. Assume that an application contains one entry-type HAP file (**entry.hap**) and two feature-type HAP files (**Feature1.hap** and **Feature2.hap**). The **Entry.hap** file can be deployed on device A and device B, the **Feature1.hap** file can be deployed only on device A, and the **Feature2.hap** can be deployed only on device B. This means that you can combine the **Entry.hap** and **Feature1.hap** files and deploy them on device A, and combine the **Entry.hap** and **Feature2.hap** files and deploy them on device B.
-- On-demand loading: You can load modules only when they are needed, reducing the package size. Specifically, you can configure some HAP files of an application to be loaded on demand. For example, if some features are not used during application startup, you can configure them to be loaded only when they are needed, rather than being loaded at startup. This can reduce the size of the application package to some extent.

-- Easier resource sharing: The resources (including public resource files and public pages) and shared objects (.so library files) required by multiple HAP files can be stored in an independent HAP file. In this way, other HAP files can obtain the resources and files by accessing the HAP, which reduces the size of the application package to some extent.
