+# Using Native APIs in Application Projects
+
+OpenHarmony applications use JavaScript (JS) when calling native APIs. The native APIs (NAPIs) provided by the **arkui_napi** repository are used to implement the interaction with JS. Currently, the **arkui_napi** repository supports some third-party **Node.js** interfaces. The names of the NAPIs are the same as those in the third-party **Node.js**. For details about the interfaces supported, see `libnapi.ndk.json` in this repository.
+
+## How to Develop
+
+The IDE has a default project that uses NAPIs. You can choose `File` > `New` > `Create Project` to create a `Native C++` project. The **cpp** directory is generated in the **main** directory. You can use the NAPIs provided by the **arkui_napi** repository for development.
+
+You can `import` the native .so that contains the JS processing logic. For example, `import hello from 'libhello.so'` to use the **libhello.so** capability. Then, the JS object created using the NAPI can be passed to the `hello` object of the application to call the native capability.
+
+## Development Guidelines
+
+### Registration
+
+* Add **static** to the **nm_register_func** function to prevent symbol conflicts with other .so files.
+* The name of the module registration entry, that is, the function decorated by **\_\_attribute\_\_((constructor))**, must be unique.
+### .so Naming Rules
+
+Each module has a .so file. For example, if the module name is `hello`, name the .so file **libhello.so**. The `nm_modname` field in `napi_module` must be `hello`, which is the same as the module name. The sample code for importing the .so file is `import hello from 'libhello.so'`.
+
+### JS Objects and Threads
+
+The Ark engine prevents NAPIs from being called to operate JS objects in non-JS threads. Otherwise, the application will crash.
+
+* The NAPIs can be used only in JS threads.
+* **env** is bound to a thread and cannot be used across threads. The JS object created by a NAPI can be used only in the thread, in which the object is created, that is, the JS object is bound to the **env** of the thread.
+
+### napi_create_async_work
+
+**napi_create_async_work** has two callbacks:
+
+* **execute**: processes service logic asynchronously. This callback is not executed by a JS thread; therefore, it cannot call any NAPI. The return value of **execute** is processed by the **complete** callback.
+
+* **complete**: calls the NAPI to encapsulate the return value of **execute** into a JS object and return it for processing. This callback is executed by a JS thread.
+
+```c++
+napi_status napi_create_async_work(napi_env env,
+                                   napi_value async_resource,
+                                   napi_value async_resource_name,
+                                   napi_async_execute_callback execute,
+                                   napi_async_complete_callback complete,
+                                   void* data,
+                                   napi_async_work* result)
+```
+
+
+
+## Example 1: Encapsulating Synchronous and Asynchronous APIs for the Storage Module
+
+### Overview
+
+This example shows how to encapsulate the synchronous and asynchronous APIs of the storage module. The storage module implements the functions of storing, obtaining, deleting, and clearing data.
+
+### API Declaration
+
+```typescript
+import { AsyncCallback } from './basic';
+declare namespace storage {
+  function get(key: string, callback: AsyncCallback<string>): void;
+  function get(key: string, defaultValue: string, callback: AsyncCallback<string>): void;
+  function get(key: string, defaultValue?: string): Promise<string>;
+  function set(key: string, value: string, callback: AsyncCallback<string>): void;
+  function remove(key: string, callback: AsyncCallback<void>): void;
+  function clear(callback: AsyncCallback<void>): void;
+  function getSync(key: string, defaultValue?: string): string;
+  function setSync(key: string, value: string): void;
+  function removeSync(key: string): void;
+  function clearClear(): void;
+}
+export default storage;
+```
+
+
+
+### Implementation
+
+You can obtain the complete code from `sample/native_module_storage/` in the **arkui_napi** repository.
+
+#### Registering the Module
+
+Register four synchronous APIs (`getSync`, `setSync`, `removeSync`, and`clearSync`) and four asynchronous APIs (`get`, `set`, `remove`, and `clear`).
+
+```c++
+/***********************************************
+ * Module export and register
+ ***********************************************/
+static napi_value StorgeExport(napi_env env, napi_value exports)
+{
+    napi_property_descriptor desc[] = {
+        DECLARE_NAPI_FUNCTION("get", JSStorageGet),
+        DECLARE_NAPI_FUNCTION("set", JSStorageSet),
+        DECLARE_NAPI_FUNCTION("remove", JSStorageDelete),
+        DECLARE_NAPI_FUNCTION("clear", JSStorageClear),
+
+        DECLARE_NAPI_FUNCTION("getSync", JSStorageGetSync),
+        DECLARE_NAPI_FUNCTION("setSync", JSStorageSetSync),
+        DECLARE_NAPI_FUNCTION("deleteSync", JSStorageDeleteSync),
+        DECLARE_NAPI_FUNCTION("clearSync", JSStorageClearSync),
+    };
+    NAPI_CALL(env, napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc));
+    return exports;
+}
+
+// Storage module
+static napi_module storage_module = {.nm_version = 1,
+                                     .nm_flags = 0,
+                                     .nm_filename = nullptr,
+                                     .nm_register_func = StorgeExport,
+                                     .nm_modname = "storage",
+                                     .nm_priv = ((void*)0),
+                                     .reserved = {0}};
+
+// Register the storage module
+extern "C" __attribute__((constructor)) void StorageRegister()
+{
+    napi_module_register(&storage_module);
+}
+```
+
+#### Implementing getSync
+
+The **getSync** function registered for the storage module is **JSStorageGetSync**. Obtain data from `gKeyValueStorage`, create a string object, and return it.
+
+```c
+static napi_value JSStorageGetSync(napi_env env, napi_callback_info info)
+{
+    GET_PARAMS(env, info, 2);
+    NAPI_ASSERT(env, argc >= 1, "requires 1 parameter");
+    char key[32] = {0};
+    size_t keyLen = 0;
+    char value[128] = {0};
+    size_t valueLen = 0;
+
+    // Parse parameters.
+    for (size_t i = 0; i < argc; i++) {
+        napi_valuetype valueType;
+        napi_typeof(env, argv[i], &valueType);
+
+        if (i == 0 && valueType == napi_string) {
+            napi_get_value_string_utf8(env, argv[i], key, 31, &keyLen);
+        } else if (i == 1 && valueType == napi_string) {
+            napi_get_value_string_utf8(env, argv[i], value, 127, &valueLen);
+            break;
+        } else {
+            NAPI_ASSERT(env, false, "type mismatch");
+        }
+    }
+
+    // Service logic for obtaining data. This example simply obtains data from a global variable.
+    auto itr = gKeyValueStorage.find(key);
+    napi_value result = nullptr;
+    if (itr != gKeyValueStorage.end()) {
+        // Use the data obtained to create a JS object of the string type.
+        napi_create_string_utf8(env, itr->second.c_str(), itr->second.length(), &result);
+    } else if (valueLen > 0) {
+        // If no data is obtained, use the default value to create a JS object.
+        napi_create_string_utf8(env, value, valueLen, &result);
+    } else {
+        NAPI_ASSERT(env, false, "key does not exist");
+    }
+    // Return the result.
+    return result;
+}
+```
+
+#### Implementing get
+
+The `get` function registered for the storage module is `JSStorageGet`.
+
+```c
+static napi_value JSStorageGet(napi_env env, napi_callback_info info)
+{
+    GET_PARAMS(env, info, 3);
+    NAPI_ASSERT(env, argc >= 1, "requires 1 parameter");
+
+    // StorageAsyncContext is a custom class used to store data during execution.
+    StorageAsyncContext* asyncContext = new StorageAsyncContext();
+
+    asyncContext->env = env;
+
+    // Obtain parameters.
+    for (size_t i = 0; i < argc; i++) {
+        napi_valuetype valueType;
+        napi_typeof(env, argv[i], &valueType);
+
+        if (i == 0 && valueType == napi_string) {
+            napi_get_value_string_utf8(env, argv[i], asyncContext->key, 31, &asyncContext->keyLen);
+        } else if (i == 1 && valueType == napi_string) {
+            napi_get_value_string_utf8(env, argv[i], asyncContext->value, 127, &asyncContext->valueLen);
+        } else if (i == 1 && valueType == napi_function) {
+            napi_create_reference(env, argv[i], 1, &asyncContext->callbackRef);
+            break;
+        } else if (i == 2 && valueType == napi_function) {
+            napi_create_reference(env, argv[i], 1, &asyncContext->callbackRef);
+        } else {

+            if (itr != gKeyValueStorage.end()) {
+                strncpy_s(asyncContext->value, 127, itr->second.c_str(), itr->second.length());

+
+### JS Sample Code
+
+```js
+import storage from 'libstorage.so';
+
+export default {
+  testGetSync() {
+  	const name = storage.getSync('name');
+    console.log('name is ' + name);
+  },
+  testGet() {

+    	console.log('error: ' + error);
+    });
+  }
+}
+```

+
+## Example 2: Binding Native and JS Objects for the NetServer Module
+
+### Overview
+
+This example shows how to implement the `on/off/once` method and bind C++ and JS objects using the **wrap** API. The NetServer module implements the network service.
+
+### API Declaration
+
+```typescript
+export class NetServer {
+  function start(port: number): void;
+  function stop(): void;
+  function on('start' | 'stop', callback: Function): void;
+  function once('start' | 'stop', callback: Function): void;
+  function off('start' | 'stop', callback: Function): void;
+}
+```
+
+### Implementation
+
+You can obtain the complete code from `sample/native_module_netserver/` in the **arkui_napi** repository.
+
+#### Registering the Module
+
+```c
+static napi_value NetServer::Export(napi_env env, napi_value exports)
+{
+    const char className[] = "NetServer";
+    napi_property_descriptor properties[] = {
+        DECLARE_NAPI_FUNCTION("start", JS_Start),
+        DECLARE_NAPI_FUNCTION("stop", JS_Stop),
+        DECLARE_NAPI_FUNCTION("on", JS_On),
+        DECLARE_NAPI_FUNCTION("once", JS_Once),
+        DECLARE_NAPI_FUNCTION("off", JS_Off),
+    };
+    napi_value netServerClass = nullptr;
+
+    napi_define_class(env, className, sizeof(className), JS_Constructor, nullptr, countof(properties), properties,
+                      &netServerClass);
+
+    napi_set_named_property(env, exports, "NetServer", netServerClass);
+
+    return exports;
+}
+```
+
+#### Binding C++ and JS Objects in a Constructor
+
+```c
+napi_value NetServer::JS_Constructor(napi_env env, napi_callback_info cbinfo)
+{
+    napi_value thisVar = nullptr;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, nullptr, nullptr, &thisVar, &data);
+
+    // C++ native object to be mapped to the JS object.
+    NetServer* netServer = new NetServer(env, thisVar);
+
+    // Use napi_wrap to bind netServer and thisVar (JS object created).
+    napi_wrap(
+        env, thisVar, netServer,
+        // The JS object is automatically released by the engine. When the JS object is released, the callback is triggered to release netServer.
+        [](napi_env env, void* data, void* hint) {
+            printf("NetServer::Destructor\n");
+            NetServer* netServer = (NetServer*)data;
+            delete netServer;
+        },
+        nullptr, nullptr);
+
+    return thisVar;
+}
+```
+
+#### Obtaining the C++ Object from the JS Object
+
+```c
+napi_value NetServer::JS_Start(napi_env env, napi_callback_info cbinfo)
+{
+    size_t argc = 1;
+    napi_value argv[1] = {0};
+    napi_value thisVar = nullptr;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, &argc, argv, &thisVar, &data);
+
+    NetServer* netServer = nullptr;
+    // Obtain the C++ object from thisVar using napi_unwrap.
+    napi_unwrap(env, thisVar, (void**)&netServer);
+
+    NAPI_ASSERT(env, argc >= 1, "requires 1 parameter");
+
+    napi_valuetype valueType;
+    napi_typeof(env, argv[0], &valueType);
+    NAPI_ASSERT(env, valueType == napi_number, "type mismatch for parameter 1");
+
+    int32_t port = 0;
+    napi_get_value_int32(env, argv[0], &port);
+
+    // Start the netServer service.
+    netServer->Start(port);
+
+    napi_value result = nullptr;
+    napi_get_undefined(env, &result);
+    return result;
+}
+```
+
+After `netServer->Start` is executed, call back the `start` event registered by `on`.
+
+```c
+int NetServer::Start(int port)
+{
+    printf("NetServer::Start thread_id: %ld \n", uv_thread_self());
+
+    struct sockaddr_in addr;
+    int r;
+
+    uv_ip4_addr("0.0.0.0", port, &addr);
+
+    r = uv_tcp_init(loop_, &tcpServer_);
+    if (r) {
+        fprintf(stderr, "Socket creation error\n");
+        return 1;
+    }
+
+    r = uv_tcp_bind(&tcpServer_, (const struct sockaddr*)&addr, 0);
+    if (r) {
+        fprintf(stderr, "Bind error\n");
+        return 1;
+    }
+
+    r = uv_listen((uv_stream_t*)&tcpServer_, SOMAXCONN, OnConnection);
+    if (r) {
+        fprintf(stderr, "Listen error %s\n", uv_err_name(r));
+        return 1;
+    }
+
+    // Trigger the start event after the service is started.
+    Emit("start", nullptr);
+
+    return 0;
+}
+```
+
+#### Registering Events (on)
+
+```c
+napi_value NetServer::JS_On(napi_env env, napi_callback_info cbinfo)
+{
+    size_t argc = 2;
+    napi_value argv[2] = {0};
+    napi_value thisVar = 0;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, &argc, argv, &thisVar, &data);
+
+    NetServer* netServer = nullptr;
+    // Obtain the NetServer pointer using napi_unwrap.
+    napi_unwrap(env, thisVar, (void**)&netServer);
+
+    NAPI_ASSERT(env, argc >= 2, "requires 2 parameter");
+
+    // Verify the parameter type.
+    napi_valuetype eventValueType;
+    napi_typeof(env, argv[0], &eventValueType);
+    NAPI_ASSERT(env, eventValueType == napi_string, "type mismatch for parameter 1");
+
+    napi_valuetype eventHandleType;
+    napi_typeof(env, argv[1], &eventHandleType);
+    NAPI_ASSERT(env, eventHandleType == napi_function, "type mismatch for parameter 2");
+
+    char type[64] = {0};
+    size_t typeLen = 0;
+
+    napi_get_value_string_utf8(env, argv[0], type, 63, &typeLen);
+
+    // Register the event handler.
+    netServer->On((const char*)type, argv[1]);
+
+    napi_value result = nullptr;
+    napi_get_undefined(env, &result);
+    return result;
+}
+```
+
+### JS Sample Code
+
+```javascript
+import { NetServer } from 'libnetserver.so';
+
+export default {
+  testNetServer() {
+  	var netServer = new NetServer();
+  	netServer.on('start', (event) => {});
+  	netServer.start(1000); // The port number is 1000. After start is executed, invoke the start callback registered.
+  }
+}
+```
+
+
+
+## Example 3: Calling Back a JS API in a Non-JS Thread
+
+### Overview
+
+This example describes how to invoke a JS callback in a non-JS thread. For example, a sensor listener is registered for a JS application. The sensor data is reported by an SA. When the SA invokes the client through Inter-Process Communication (IPC), the execution thread is an IPC thread, which is different from the JS thread of the SA. In this case, the JS callback must be thrown to the JS thread to execute. Otherwise, the application will crash.
+
+### Implementation
+
+You can obtain the complete code from `sample/native_module_callback/` in the **arkui_napi** repository.
+
+#### Registering the Module
+
+Register the `test` API to pass in a parameter.
+
+```c++

+
+## 2D图形绘制开发步骤
+
+以下步骤描述了在**OpenHarmony**如何使用 **native drawing** 模块的画布画笔绘制一个基本的2D图形：
+
+1. **创建Bitmap实例**。使用 **drawing_bitmap.h** 的 **OH_Drawing_BitmapCreate** 接口创建一个Bitmap实例 **cBitmap**，并使用 **OH_Drawing_BitmapBuild** 指定其长宽大小和像素格式。
+
+    ```c++
+    // 创建一个bitmap对象
+    OH_Drawing_Bitmap* cBitmap = OH_Drawing_BitmapCreate();
+    // 定义bitmap的像素格式
+    OH_Drawing_BitmapFormat cFormat {COLOR_FORMAT_RGBA_8888, ALPHA_FORMAT_OPAQUYE};
+    // 构造对应格式的bitmap
+    OH_Drawing_BitmapBuild(cBitmap, width, height, &cFormat);
+    ```
+
+2. **创建画布实例**。使用 **drawing_canvas.h** 的 **OH_Drawing_CanvasCreate** 接口创建一个画布实例 **cCanvas**，并使用 **OH_Drawing_CanvasBind** 接口将 **cBitmap** 实例绑定到 **cCanvas** 上，后续在画布上绘制的内容会输出到绑定的 **cBitmap** 实例中。
+
+    ```c++
+    // 创建一个canvas对象
+    OH_Drawing_Canvas* cCanvas = OH_Drawing_CanvasCreate();
+    // 将画布与bitmap绑定，画布画的内容会输出到绑定的bitmap内存中
+    OH_Drawing_CanvasBind(cCanvas, cBitmap);
+    // 使用白色清除画布内容
+    OH_Drawing_CanvasClear(cCanvas, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0xFF, 0xFF));
+    ```
+
+3. **构造Path形状**。使用 **drawing_path.h** 提供的接口完成一个五角星形状的构造 **cPath**。
+
+    ```c++
+    int len = 300;
+
+    float aX = 500;
+    float aY = 500;
+
+    float dX = aX - len * std::sin(18.0f);
+    float dY = aY + len * std::cos(18.0f);
+
+    float cX = aX + len * std::sin(18.0f);
+    float cY = dY;
+
+    float bX = aX + (len / 2.0);
+    float bY = aY + std::sqrt((cX - dX) * (cX - dX) + (len / 2.0) * (len / 2.0));
+
+    float eX = aX - (len / 2.0);
+    float eY = bY;
+
+    // 创建一个path对象，然后使用接口连接成一个五角星形状
+    OH_Drawing_Path* cPath = OH_Drawing_PathCreate();
+    // 指定path的起始位置
+    OH_Drawing_PathMoveTo(cPath, aX, aY);
+    // 用直线连接到目标点
+    OH_Drawing_PathLineTo(cPath, bX, bY);
+    OH_Drawing_PathLineTo(cPath, cX, cY);
+    OH_Drawing_PathLineTo(cPath, dX, dY);
+    OH_Drawing_PathLineTo(cPath, eX, eY);
+    // 闭合形状，path绘制完毕
+    OH_Drawing_PathClose(cPath);
+    ```
+
+4. **设置画笔和画刷样式**。使用 **drawing_pen.h** 的 **OH_Drawing_PenCreate** 接口创建一个画笔实例 **cPen**, 并设置抗锯齿、颜色、线宽等属性，画笔用于形状边框线的绘制。使用**drawing_brush.h** 的 **OH_Drawing_BrushCreate** 接口创建一个画刷实例 **cBrush**, 并设置填充颜色， 画刷用于形状内部的填充。使用 **drawing_canvas.h** 的 **OH_Drawing_CanvasAttachPen** 和 **OH_Drawing_CanvasAttachBrush** 接口将画笔画刷的实例设置到画布实例中。
+
+    ```c++
+    // 创建一个画笔Pen对象，Pen对象用于形状的边框线绘制
+    OH_Drawing_Pen* cPen = OH_Drawing_PenCreate();
+    OH_Drawing_PenSetAntiAlias(cPen, true);
+    OH_Drawing_PenSetColor(cPen, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0x00, 0x00));
+    OH_Drawing_PenSetWidth(cPen, 10.0);
+    OH_Drawing_PenSetJoin(cPen, LINE_ROUND_JOIN);
+    // 将Pen画笔设置到canvas中
+    OH_Drawing_CanvasAttachPen(cCanvas, cPen);
+
+    // 创建一个画刷Brush对象，Brush对象用于形状的填充
+    OH_Drawing_Brush* cBrush = OH_Drawing_BrushCreate();
+    OH_Drawing_BrushSetColor(cBrush, OH_Drawing_ColorSetArgb(0xFF, 0x00, 0xFF, 0x00));
+
+    // 将Brush画刷设置到canvas中
+    OH_Drawing_CanvasAttachBrush(cCanvas, cBrush);
+    ```
+
+5. **绘制Path形状**。使用 **drawing_canvas.h** 的 **OH_Drawing_CanvasDrawPath** 接口将五角星绘制到画布上，绘制完毕后不再使用的实例需要调用对应的接口进行销毁。
+
+    ```c++
+    // 在画布上画path的形状，五角星的边框样式为pen设置，颜色填充为Brush设置
+    OH_Drawing_CanvasDrawPath(cCanvas, cPath);
+    // 销毁创建的对象
+    OH_Drawing_BrushDestory(cBrush);
+    OH_Drawing_PenDestory(cPen);
+    OH_Drawing_PathDestory(cPath);
+    ```
+
+6. **获取像素数据**。使用 **drawing_bitmap.h** 的 **OH_Drawing_BitmapGetPixels** 接口获取到画布绑定bitmap实例的像素地址，该地址指向的内存包含画布刚刚绘制的像素数据。
+
+    ```c++
+    // 画完后获取像素地址，地址指向的内存包含画布画的像素数据
+    void* bitmapAddr = OH_Drawing_BitmapGetPixels(cBitmap);
+    auto ret = memcpy_s(addr, addrSize, bitmapAddr, addrSize);
+    if (ret != EOK) {
+        LOGI("memcpy_s failed");
+    }
+    // 销毁canvas对象
+    OH_Drawing_CanvasDestory(cCanvas);
+    // 销毁bitmap对象
+    OH_Drawing_BitmapDestory(cBitmap);
+    ```
+
+## 文本绘制显示开发步骤
+
+以下步骤描述了在OpenHarmony中，如何使用**native drawing**模块的文字显示功能：
+1. **创建画布和bitmap实例**。
+
+    ```c++
+    // 创建bitmap
+    OH_Drawing_Bitmap* cBitmap = OH_Drawing_BitmapCreate();
+    OH_Drawing_BitmapFormat cFormat {COLOR_FORMAT_RGBA_8888, ALPHA_FORMAT_OPAQUE};
+    OH_Drawing_BitmapBuild(cBitmap, width, height, &cFormat);
+    // 创建canvas
+    OH_Drawing_Canvas* cCanvas = OH_Drawing_CanvasCreate();
+    OH_Drawing_CanvasBind(cCanvas, cBitmap);
+    OH_Drawing_CanvasClear(cCanvas, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0xFF, 0xFF));
+    ```
+  
+2. **设置排版风格**。
+
+    ```c++
+    // 选择左对齐/居中对齐等排版属性
+    OH_Drawing_TypographyStyle* typoStyle = OH_Drawing_CreateTypographyStyle();
+    OH_Drawing_SetTypographyTextDirection(typoStyle, TEXT_DIRECTION_LTR);
+    OH_Drawing_SetTypographyTextAlign(typoStyle, TEXT_ALIGN_LEFT);
+    ```
+
+3. **设置文本风格**。
+
+    ```c++
+    // 设置文字颜色，例如黑色
+    OH_Drawing_TextStyle* txtStyle = OH_Drawing_CreateTextStyle();
+    OH_Drawing_SetTextStyleColor(txtStyle, OH_Drawing_ColorSetArgb(0xFF, 0x00, 0x00, 0x00));
+    // 设置文字大小、字重等属性
+    double fontSize = 30;
+    OH_Drawing_SetTextStyleFontSize(txtStyle, fontSize);
+    OH_Drawing_SetTextStyleFontWeight(txtStyle, FONT_WEIGHT_400);
+    OH_Drawing_SetTextStyleBaseLine(txtStyle, TEXT_BASELINE_ALPHABETIC);
+    OH_Drawing_SetTextStyleFontHeight(txtStyle, 1);
+    // 设置字体类型等
+    const char* fontFamilies[] = {"Roboto"};
+    OH_Drawing_SetTextStyleFontFamilies(txtStyle, 1, fontFamilies);
+    OH_Drawing_SetTextStyleFontStyle(txtStyle, FONT_STYLE_NORMAL);
+    OH_Drawing_SetTextStyleLocale(txtStyle, "en");
+    ```
+
+4. **生成最终文字显示效果**。
+
+    ```c++
+    OH_Drawing_TypographyCreate* handler = OH_Drawing_CreateTypographyHandler(typoStyle,
+        OH_Drawing_CreateFontCollection());
+    OH_Drawing_TypographyHandlerPushTextStyle(handler, txtStyle);
+    // 设置文字内容
+    const char* text = "OpenHarmony\n";
+    OH_Drawing_TypographyHandlerAddText(handler, text);
+    OH_Drawing_TypographyHandlerPopTextStyle(handler);
+    OH_Drawing_Typography* typography = OH_Drawing_CreateTypography(handler);
+    // 设置页面最大宽度
+    double maxWidth = 800.0;
+    OH_Drawing_TypographyLayout(typography, maxWidth);
+    // 设置文字显示起始位置
+    double position[2] = {10.0, 15.0};
+    OH_Drawing_TypographyPaint(typography, cCanvas, position[0], position[1]);
+    ```

zh-cn/application-dev/napi/napi-guidelines.md

+# Native API在应用工程中的使用指导
+
+OpenHarmony的应用必须用js来桥接native。需要使用ace_napi仓中提供的napi接口来处理js交互。napi提供的接口名与三方Node.js一致，目前支持部分接口，符号表见仓下的该文件`libnapi.ndk.json`。
+
+## 开发流程：
+
+IDE中会包含使用Native API的默认工程，使用`File`->`New`->`Create Project`创建`Native C++`模板工程。创建后在`main`目录下会包含`cpp`目录，可以使用ace_napi仓下提供的napi接口进行开发。
+
+js侧通过`import`引入native侧包含处理js逻辑的so，如：`import hello from 'libhello.so'`，意为使用libhello.so的能力，native侧通过napi接口创建的js对象会给到应用js侧的`hello`对象。
+
+## 开发建议：
+
+### 1、注册建议
+
+* nm_register_func对应的函数需要加上static，防止与其他so里的符号冲突。
+* 模块注册的入口，即使用\_\_attribute\_\_((constructor))修饰的函数的函数名需要确保不与其他模块重复。
+### 2、so命名规则
+
+* 每个模块对应一个so
+* 如模块名为`hello`，则so的名字为`libhello.so`，`napi_module`中`nm_modname`字段应为`hello`，大小写与模块名保持一致，应用使用时写作：`import hello from 'libhello.so'`
+
+### 3、js对象线程限制
+
+ark引擎会对js对象线程使用进行保护，不正确使用会引起应用crash。
+
+* napi接口只能在js线程使用。
+* env与线程绑定，不能跨线程使用。native侧js对象只能在创建时的线程使用，即与线程所持有的env绑定。
+
+### 4. napi_create_async_work接口说明
+
+napi_create_async_work里有两个回调：
+
+* execute：用于异步处理业务逻辑。因为不在JS线程中，所以不允许调用napi的接口。业务逻辑的返回值可以返回到complete回调中处理。
+
+* complete：可以调用napi的接口，将execute中的返回值封装成JS对象返回。此回调在JS线程中执行。
+
+```c++
+napi_status napi_create_async_work(napi_env env,
+                                   napi_value async_resource,
+                                   napi_value async_resource_name,
+                                   napi_async_execute_callback execute,
+                                   napi_async_complete_callback complete,
+                                   void* data,
+                                   napi_async_work* result)
+```
+
+
+
+## 示例一，storage 模块——同步异步接口封装
+
+### 模块简介
+
+本例通过实现 `storage` 模块展示了同步和异步方法的封装。`storage ` 模块实现了数据的保存、获取、删除、清除功能。
+
+### 接口声明
+
+```typescript
+import { AsyncCallback } from './basic';
+declare namespace storage {
+  function get(key: string, callback: AsyncCallback<string>): void;
+  function get(key: string, defaultValue: string, callback: AsyncCallback<string>): void;
+  function get(key: string, defaultValue?: string): Promise<string>;
+  function set(key: string, value: string, callback: AsyncCallback<string>): void;
+  function remove(key: string, callback: AsyncCallback<void>): void;
+  function clear(callback: AsyncCallback<void>): void;
+  function getSync(key: string, defaultValue?: string): string;
+  function setSync(key: string, value: string): void;
+  function removeSync(key: string): void;
+  function clearClear(): void;
+}
+export default storage;
+```
+
+
+
+### 具体实现
+
+完整代码参见仓下路径：`sample/native_module_storage/`
+
+#### 模块注册
+
+如下，注册了4个同步接口（`getSync`、`setSync`、`removeSync`、`clearSync`）、4个异步接口（`get`、`set`、`remove`、`clear`）。
+
+```c++
+/***********************************************
+ * Module export and register
+ ***********************************************/
+static napi_value StorgeExport(napi_env env, napi_value exports)
+{
+    napi_property_descriptor desc[] = {
+        DECLARE_NAPI_FUNCTION("get", JSStorageGet),

+
+#### getSync 函数实现
+
+如上注册时所写，`getSync` 对应的函数是 `JSStorageGetSync` 。从 `gKeyValueStorage` 中获取数据后，创建一个字符串对象并返回。
+

+
+## 示例二，NetServer 模块——native与js对象绑定
+
+### 模块简介
+
+本例展示了`on/off/once`订阅方法的实现，同时也包含了 C++ 与 JS 对象通过 wrap 接口的绑定。NetServer 模块实现了一个网络服务。
+
+### 接口声明
+
+```typescript
+export class NetServer {
+  function start(port: number): void;
+  function stop(): void;
+  function on('start' | 'stop', callback: Function): void;
+  function once('start' | 'stop', callback: Function): void;
+  function off('start' | 'stop', callback: Function): void;
+}
+```
+
+### 具体实现
+
+完整代码参见：`sample/native_module_netserver/`
+
+#### 模块注册
+
+```c
+static napi_value NetServer::Export(napi_env env, napi_value exports)
+{
+    const char className[] = "NetServer";
+    napi_property_descriptor properties[] = {
+        DECLARE_NAPI_FUNCTION("start", JS_Start),
+        DECLARE_NAPI_FUNCTION("stop", JS_Stop),
+        DECLARE_NAPI_FUNCTION("on", JS_On),
+        DECLARE_NAPI_FUNCTION("once", JS_Once),
+        DECLARE_NAPI_FUNCTION("off", JS_Off),
+    };
+    napi_value netServerClass = nullptr;
+
+    napi_define_class(env, className, sizeof(className), JS_Constructor, nullptr, countof(properties), properties,
+                      &netServerClass);
+
+    napi_set_named_property(env, exports, "NetServer", netServerClass);
+
+    return exports;
+}
+```
+
+#### 在构造函数中绑定 C++ 与 JS 对象
+
+```c
+napi_value NetServer::JS_Constructor(napi_env env, napi_callback_info cbinfo)
+{
+    napi_value thisVar = nullptr;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, nullptr, nullptr, &thisVar, &data);
+
+    // C++ Native对象，准备与JS对象映射在一起
+    NetServer* netServer = new NetServer(env, thisVar);
+
+    // 使用napi_wrap将netServer与thisVar（即当前创建的这个JS对象）做绑定
+    napi_wrap(
+        env, thisVar, netServer,
+        // JS对象由引擎自动回收释放，当JS对象释放时触发该回调，在改回调中释放netServer
+        [](napi_env env, void* data, void* hint) {
+            printf("NetServer::Destructor\n");
+            NetServer* netServer = (NetServer*)data;
+            delete netServer;
+        },
+        nullptr, nullptr);
+
+    return thisVar;
+}
+```
+
+#### 从 JS 对象中取出 C++ 对象
+
+```c
+napi_value NetServer::JS_Start(napi_env env, napi_callback_info cbinfo)
+{
+    size_t argc = 1;
+    napi_value argv[1] = {0};
+    napi_value thisVar = nullptr;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, &argc, argv, &thisVar, &data);
+
+    NetServer* netServer = nullptr;
+    // 通过napi_unwrap从thisVar中取出C++对象
+    napi_unwrap(env, thisVar, (void**)&netServer);
+
+    NAPI_ASSERT(env, argc >= 1, "requires 1 parameter");
+
+    napi_valuetype valueType;
+    napi_typeof(env, argv[0], &valueType);
+    NAPI_ASSERT(env, valueType == napi_number, "type mismatch for parameter 1");
+
+    int32_t port = 0;
+    napi_get_value_int32(env, argv[0], &port);
+
+    // 开启服务
+    netServer->Start(port);
+
+    napi_value result = nullptr;
+    napi_get_undefined(env, &result);
+    return result;
+}
+```
+
+`netServer->Start`后回调通过`on`注册的`start`事件。
+
+```c
+int NetServer::Start(int port)
+{
+    printf("NetServer::Start thread_id: %ld \n", uv_thread_self());
+
+    struct sockaddr_in addr;
+    int r;
+
+    uv_ip4_addr("0.0.0.0", port, &addr);
+
+    r = uv_tcp_init(loop_, &tcpServer_);
+    if (r) {
+        fprintf(stderr, "Socket creation error\n");
+        return 1;
+    }
+
+    r = uv_tcp_bind(&tcpServer_, (const struct sockaddr*)&addr, 0);
+    if (r) {
+        fprintf(stderr, "Bind error\n");
+        return 1;
+    }
+
+    r = uv_listen((uv_stream_t*)&tcpServer_, SOMAXCONN, OnConnection);
+    if (r) {
+        fprintf(stderr, "Listen error %s\n", uv_err_name(r));
+        return 1;
+    }
+
+    // 服务启动后触发“start”事件
+    Emit("start", nullptr);
+
+    return 0;
+}
+```
+
+#### 注册或释放（on/off/once）事件，以 on 为例
+
+```c
+napi_value NetServer::JS_On(napi_env env, napi_callback_info cbinfo)
+{
+    size_t argc = 2;
+    napi_value argv[2] = {0};
+    napi_value thisVar = 0;
+    void* data = nullptr;
+    napi_get_cb_info(env, cbinfo, &argc, argv, &thisVar, &data);
+
+    NetServer* netServer = nullptr;
+    // 通过napi_unwrap取出NetServer指针
+    napi_unwrap(env, thisVar, (void**)&netServer);
+
+    NAPI_ASSERT(env, argc >= 2, "requires 2 parameter");
+
+    // 参数类型校验
+    napi_valuetype eventValueType;
+    napi_typeof(env, argv[0], &eventValueType);
+    NAPI_ASSERT(env, eventValueType == napi_string, "type mismatch for parameter 1");
+
+    napi_valuetype eventHandleType;
+    napi_typeof(env, argv[1], &eventHandleType);
+    NAPI_ASSERT(env, eventHandleType == napi_function, "type mismatch for parameter 2");
+
+    char type[64] = {0};
+    size_t typeLen = 0;
+
+    napi_get_value_string_utf8(env, argv[0], type, 63, &typeLen);
+
+    // 注册事件handler
+    netServer->On((const char*)type, argv[1]);
+
+    napi_value result = nullptr;
+    napi_get_undefined(env, &result);
+    return result;
+}
+```
+
+### JS Sample Code
+
+```javascript
+import { NetServer } from 'libnetserver.so';
+
+export default {
+  testNetServer() {
+  	var netServer = new NetServer();
+  	netServer.on('start', (event) => {});
+  	netServer.start(1000); // 端口号1000, start完成后回调上面注册的 “start” 回调
+  }
+}
+```
+
+
+
+## 示例三，在非JS线程中回调JS接口
+
+### 模块简介
+
+本模块介绍如何在非JS线程中回调JS应用的回调函数。例如JS应用中注册了某个sensor的监听，这个sensor的数据是由一个SA服务来上报的，当SA通过IPC调到客户端时，此时的执行线程是一个IPC通信线程，与应用的JS线程是两个不同的线程。这时就需要将执行JS回调的任务抛到JS线程中才能执行，否则会出现崩溃。
+
+### 具体实现
+
+完整代码参见：`sample/native_module_callback/`
+
+#### 模块注册
+
+如下，注册了1个接口`test`，会传入一个参数，类型为包含一个参数的函数。
+
+```c++

+    NativeResourceManager* nativeResourceManager = nullptr;
+    std::string path;
+    if (i == 0 && valueType == napi_string) {
+        // 解析第一个参数，参数为相对rawfile目录的文件/目录路径。
+        ......
+        path = buf.data();
+    } else if (i == 1 && valueType == napi_object) {

+DEBUG：比INFO级别更详细的流程记录，通过该级别的日志可以更详细地分析业务流程和定位分析问题。DEBUG级别的日志在正式发布版本中默认不会被打印，只有在调试版本或打开调试开关的情况下才会打印。 
+
+INFO：用来记录业务关键流程节点，可以还原业务的主要运行过程；用来记录非正常情况信息，但这些情况都是可以预期的(如无网络信号、登录失败等)。这些日志都应该由该业务内处于支配地位的模块来记录，避免在多个被调用的模块或低级函数中重复记录。 
+
+WARN：发生了较为严重的非预期情况，但是对用户影响不大，程序可以自动恢复或通过简单的操作就可以恢复的问题。
+
+ERROR：程序或功能发生了错误，该错误会影响功能的正常运行或用户的正常使用，可以恢复但恢复代价较高，如重置数据等。 
+
+FATAL：重大致命异常，表明程序或功能即将崩溃，故障无法恢复。

+**Description:**
+
+HiLog模块日志接口定义，通过这些接口实现日志打印相关功能。
+
+用户输出日志时，先定义日志所属业务领域、日志TAG，然后按照类型、级别选择对应API，指定参数隐私标识输出日志内容。 业务领域：指定日志所对应的业务领域，用户自定义使用，用于标识业务的子系统、模块。16进制整数，范围0x0~0xFFFF。 日志TAG：字符串常量，用于标识调用所在的类或者业务。 日志级别：DEBUG、INFO、WARN、ERROR、FATAL。 参数格式：类printf的方式，包括格式字符串（包括参数类型标识）和变参。 隐私参数标识：在格式字符串每个参数中符号后类型前增加{public}、{private}标识。注意：每个参数未指定隐私标识时，缺省为隐私。 使用示例： 定义业务领域、TAG： \#define LOG_DOMAIN 0x0201 \#define LOG_TAG "MY_TAG" 日志打印： HILOG_WARN([LOG_APP](_hi_log.md#ggaf67907baa897e9fb84df0cb89795b87ca84f0546432a39b6f5e8a777d5cf667b5), "Failed to visit %{private}s, reason:%{public}d.", url, errno); 结果输出： 05-06 15:01:06.870 1051 1051 W 0201/MY_TAG: Failed to visit <private>, reason:503.
