'')); } catch (e) { print(e.toString()); } ``` 使用 `close` 方法销毁 quickjs 实例，其在再次调用 `evaluate` 时将会重建。当不再需要 `FlutterQjs` 对象时，关闭 `port` 参数来结束事件循环。**在 v0.3.3 后增加了引用检查，可能会抛出异常**。 ```dart try { engine.port.close(); // stop dispatch loop engine.close(); // close engine } on JSError catch(e) { print(e); // catch reference leak exception } engine = null; ``` dart 与 js 间数据以如下规则转换： | dart | js | | ---------------------------- | ---------- | | Bool | boolean | | Int | number | | Double | number | | String | string | | Uint8List | ArrayBuffer| | List | Array | | Map | Object | | Function(arg1, arg2, ..., {thisVal})
JSInvokable.invoke(\[arg1, arg2, ...\], thisVal) | function.call(thisVal, arg1, arg2, ...) | | Future | Promise | | JSError | Error | | Object | DartObject | ## 使用模块 插件支持 ES6 模块方法 `import`。使用 `moduleHandler` 来处理模块请求： ```dart final engine = FlutterQjs( moduleHandler: (String module) { if(module == "hello") return "export default (name) => `hello \${name}!`;"; throw Exception("Module Not found"); }, ); ``` 在JavaScript中，`import` 方法用以获取模块： ```javascript import("hello").then(({default: greet}) => greet("world")); ``` **注：** 模块将只被编译一次. 调用 `FlutterQjs.close` 再 `evaluate` 来重置模块缓存。 若要使用异步方法来处理模块请求，请参见 [在 isolate 中运行](#在-isolate-中运行)。 ## 在 isolate 中运行 创建 `IsolateQjs` 对象，设置 `moduleHandler` 来处理模块请求。 现在可以使用异步函数来获得模块字符串，如 `rootBundle.loadString`： ```dart final engine = IsolateQjs( moduleHandler: (String module) async { return await rootBundle.loadString( "js/" + module.replaceFirst(new RegExp(r".js$"), "") + ".js"); }, ); // not need engine.dispatch(); ``` 与在主线程运行一样，使用 `evaluate` 方法运行js脚本。在isolate中，所有结果都将异步返回，使用 `await` 来获取结果： ```dart try { print(await engine.evaluate(code ?? '')); } catch (e) { print(e.toString()); } ``` 使用 `close` 方法销毁 isolate 线程，其在再次调用 `evaluate` 时将会重建。 ## 调用 Dart 函数 Js脚本返回函数将被转换为 `JSInvokable`。 **它不能像 `Function` 一样调用，请使用 `invoke` 方法来调用**： ```dart (func as JSInvokable).invoke([arg1, arg2], thisVal); ``` **注：** 返回 `JSInvokable` 可能造成引用泄漏，需要手动调用 `free` 来释放引用： ```dart (obj as JSRef).free(); // or JSRef.freeRecursive(obj); ``` 传递给 `JSInvokable` 的参数将自动释放. 使用 `dup` 来保持引用： ```dart (obj as JSRef).dup(); // or JSRef.dupRecursive(obj); ``` 自 v0.3.0 起，dart 函数可以作为参数传递给 `JSInvokable`，且 `channel` 函数不再默认内置。可以使用如下方法将 dart 函数赋值给全局，例如，使用 `Dio` 来为 qjs 提供 http 支持： ```dart final setToGlobalObject = await engine.evaluate("(key, val) => { this[key] = val; }"); await setToGlobalObject.invoke(["http", (String url) { return Dio().get(url).then((response) => response.data); }]); setToGlobalObject.free(); ``` 在 isolate 模式下，只有顶层和静态函数能作为参数传给 `JSInvokable`，函数将在 isolate 线程中调用。 使用 `IsolateFunction` 来传递局部函数（将在主线程中调用）： ```dart await setToGlobalObject.invoke([ "http", IsolateFunction((String url) { return Dio().get(url).then((response) => response.data); }), ]); ``` ================================================ FILE: README.md ================================================ # flutter_qjs ![Pub](https://img.shields.io/pub/v/flutter_qjs.svg) ![Test](https://github.com/ekibun/flutter_qjs/workflows/Test/badge.svg) [English](README.md) | [中文](README-CN.md) This plugin is a simple js engine for flutter using the `quickjs` project with `dart:ffi`. Plugin currently supports all the platforms except web! ## Getting Started ### Basic usage Firstly, create a `FlutterQjs` object, then call `dispatch` to establish event loop: ```dart final engine = FlutterQjs( stackSize: 1024 * 1024, // change stack size here. ); engine.dispatch(); ``` Use `evaluate` method to run js script, it runs synchronously, you can use await to resolve `Promise`: ```dart try { print(engine.evaluate(code ?? '')); } catch (e) { print(e.toString()); } ``` Method `close` can destroy quickjs runtime that can be recreated again if you call `evaluate`. Parameter `port` should be close to stop `dispatch` loop when you do not need it. **Reference leak exception will be thrown since v0.3.3** ```dart try { engine.port.close(); // stop dispatch loop engine.close(); // close engine } on JSError catch(e) { print(e); // catch reference leak exception } engine = null; ``` Data conversion between dart and js are implemented as follow: | dart | js | | ---------------------------- | ---------- | | Bool | boolean | | Int | number | | Double | number | | String | string | | Uint8List | ArrayBuffer| | List | Array | | Map | Object | | Function(arg1, arg2, ..., {thisVal})
JSInvokable.invoke(\[arg1, arg2, ...\], thisVal) | function.call(thisVal, arg1, arg2, ...) | | Future | Promise | | JSError | Error | | Object | DartObject | ## Use Modules ES6 module with `import` function is supported and can be managed in dart with `moduleHandler`: ```dart final engine = FlutterQjs( moduleHandler: (String module) { if(module == "hello") return "export default (name) => `hello \${name}!`;"; throw Exception("Module Not found"); }, ); ``` then in JavaScript, `import` function is used to get modules: ```javascript import("hello").then(({default: greet}) => greet("world")); ``` **notice:** Module handler should be called only once for each module name. To reset the module cache, call `FlutterQjs.close` then `evaluate` again. To use async function in module handler, try [run on isolate thread](#Run-on-Isolate-Thread) ## Run on Isolate Thread Create a `IsolateQjs` object, pass handlers to resolving modules. Async function such as `rootBundle.loadString` can be used now to get modules: ```dart final engine = IsolateQjs( moduleHandler: (String module) async { return await rootBundle.loadString( "js/" + module.replaceFirst(new RegExp(r".js$"), "") + ".js"); }, ); // not need engine.dispatch(); ``` Same as run on main thread, use `evaluate` to run js script. In isolate, everything returns asynchronously, use `await` to get the result: ```dart try { print(await engine.evaluate(code ?? '')); } catch (e) { print(e.toString()); } ``` Method `close` can destroy isolate thread that will be recreated again if you call `evaluate`. ## Use Dart Function (Breaking change in v0.3.0) Js script returning function will be converted to `JSInvokable`. **It does not extend `Function`, use `invoke` method to invoke it**: ```dart (func as JSInvokable).invoke([arg1, arg2], thisVal); ``` **notice:** evaluation returning `JSInvokable` may cause reference leak. You should manually call `free` to release JS reference. ```dart (obj as JSRef).free(); // or JSRef.freeRecursive(obj); ``` Arguments passed into `JSInvokable` will be freed automatically. Use `dup` to keep the reference. ```dart (obj as JSRef).dup(); // or JSRef.dupRecursive(obj); ``` Since v0.3.0, you can pass a function to `JSInvokable` arguments, and `channel` function is no longer included by default. You can use js function to set dart object globally. For example, use `Dio` to implement http in qjs: ```dart final setToGlobalObject = await engine.evaluate("(key, val) => { this[key] = val; }"); await setToGlobalObject.invoke(["http", (String url) { return Dio().get(url).then((response) => response.data); }]); setToGlobalObject.free(); ``` In isolate, top level function passed in `JSInvokable` will be invoked in isolate thread. Use `IsolateFunction` to pass a instant function: ```dart await setToGlobalObject.invoke([ "http", IsolateFunction((String url) { return Dio().get(url).then((response) => response.data); }), ]); ``` ================================================ FILE: android/.classpath ================================================ ================================================ FILE: android/.gitignore ================================================ *.iml .gradle /local.properties /.idea/workspace.xml /.idea/libraries .DS_Store /build /captures /.cxx ================================================ FILE: android/.project ================================================ flutter_qjs Project android created by Buildship. org.eclipse.jdt.core.javabuilder org.eclipse.buildship.core.gradleprojectbuilder org.eclipse.jdt.core.javanature org.eclipse.buildship.core.gradleprojectnature ================================================ FILE: android/.settings/org.eclipse.buildship.core.prefs ================================================ arguments= auto.sync=false build.scans.enabled=false connection.gradle.distribution=GRADLE_DISTRIBUTION(VERSION(6.3)) connection.project.dir= eclipse.preferences.version=1 gradle.user.home= java.home=C\:/Program Files/JetBrains/IntelliJ IDEA Community Edition 2019.3.2/jbr jvm.arguments= offline.mode=false override.workspace.settings=true show.console.view=true show.executions.view=true ================================================ FILE: android/build.gradle ================================================ group 'soko.ekibun.flutter_qjs' version '1.0-SNAPSHOT' buildscript { ext.kotlin_version = '1.3.50' repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.5.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } rootProject.allprojects { repositories { google() jcenter() maven { url 'https://jitpack.io' } } } apply plugin: 'com.android.library' apply plugin: 'kotlin-android' android { compileSdkVersion 28 sourceSets { main.java.srcDirs += 'src/main/kotlin' } defaultConfig { minSdkVersion 16 } lintOptions { disable 'InvalidPackage' } kotlinOptions { jvmTarget = "1.8" } externalNativeBuild { cmake { path "src/main/cxx/CMakeLists.txt" version "3.10.2" } } } dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" // implementation 'com.github.abner.oasis-jsbridge-android:oasis-jsbridge-quickjs:0.11.0' } ================================================ FILE: android/gradle/wrapper/gradle-wrapper.properties ================================================ distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip ================================================ FILE: android/gradle.properties ================================================ org.gradle.jvmargs=-Xmx1536M android.enableR8=true android.useAndroidX=true android.enableJetifier=true ================================================ FILE: android/settings.gradle ================================================ rootProject.name = 'flutter_qjs' ================================================ FILE: android/src/main/AndroidManifest.xml ================================================ ================================================ FILE: android/src/main/cxx/CMakeLists.txt ================================================ # For more information about using CMake with Android Studio, read the # documentation: https://d.android.com/studio/projects/add-native-code.html # Sets the minimum version of CMake required to build the native library. cmake_minimum_required(VERSION 3.4.1) set(JNI_LIB_NAME qjs) # Creates and names a library, sets it as either STATIC # or SHARED, and provides the relative paths to its source code. # You can define multiple libraries, and CMake builds them for you. # Gradle automatically packages shared libraries with your APK. include("${CMAKE_CURRENT_SOURCE_DIR}/../../../../cxx/quickjs.cmake") add_library( # Sets the name of the library. ${JNI_LIB_NAME} # Sets the library as a shared library.
