我正在尝试在网络工作者的打字稿中使用外部模块,但遇到了问题。测试示例的所有代码都位于 www.windward.net/temp/WebWorkerRequireJs.zip(下面列出了关键代码)。
我想要的打字稿(这在主线程中工作得很好)是:
import myClass = require('my-class');
class WorkerThread {
}
self.onmessage = function (e) {
console.log("client received message = " + e.data);
var mc = new myClass.MyClass();
console.log("worker thread toUpper = " + mc.toUpper("dave"));
self.postMessage("from client");
}
这会生成以下 javascript,由于未定义定义而失败:
define(["require", "exports", 'my-class'], function(require, exports, __myClass__) {
var myClass = __myClass__;
var WorkerThread = (function () {
function WorkerThread() {
}
return WorkerThread;
})();
self.onmessage = function (e) {
console.log("client received message = " + e.data);
var mc = new myClass.MyClass();
console.log("worker thread toUpper = " + mc.toUpper("dave"));
self.postMessage("from client");
};
});
//# sourceMappingURL=worker-thread.js.map
所以第 1 步,我添加了 importScripts 并调用了这个 .js 文件:
importScripts('../../scripts/require.js');
define(["require", "exports", 'my-class'], function(require, exports, __myClass__) {
var myClass = __myClass__;
var WorkerThread = (function () {
function WorkerThread() {
}
return WorkerThread;
})();
self.onmessage = function (e) {
console.log("client received message = " + e.data);
var mc = new myClass.MyClass();
console.log("worker thread toUpper = " + mc.toUpper("dave"));
self.postMessage("from client");
};
});
//# sourceMappingURL=worker-thread.js.map
这不起作用并给出错误:
Uncaught Error: Mismatched anonymous define() module: function (require, exports, __myClass__) {
var myClass = __myClass__;
var WorkerThread = (function () {
function WorkerThread() {
}
return WorkerThread;
})();
self.onmessage =...<omitted>...ch
然后我将“定义”切换为“要求”,这有效:
importScripts('../../scripts/require.js');
require(["require", "exports", 'my-class'], function(require, exports, __myClass__) {
debugger;
var myClass = __myClass__;
var WorkerThread = (function () {
function WorkerThread() {
}
return WorkerThread;
})();
self.onmessage = function (e) {
console.log("client received message = " + e.data);
var mc = new myClass.MyClass();
console.log("worker thread toUpper = " + mc.toUpper("dave"));
self.postMessage("from client");
};
});
//# sourceMappingURL=worker-thread.js.map
这就引出了一个问题——我如何让打字稿生成它以便它运行。解决方案是设置一个主 javascript 文件,该文件是初始 Web Worker 应用程序,然后调用打字稿部分?如果是这样,我该如何设置?
或者是以某种方式告诉打字稿编译器从定义更改为 require 并插入 importScripts() 的解决方案?
更新: 看起来(最好的?)解决方案是主要的 Web Worker 文件是一个 javascript 文件。它具有 importScripts() 和主打字稿类的要求。您创建该类并从那里运行。此时,使用“定义”的打字稿“导入”就可以了。到目前为止...
工作文件不会由 AMD 加载程序加载,而是由浏览器加载。 因此,您需要突破 AMD 代码生成并自己使用原始“require”调用。
importScripts('../../scripts/require.js');
require(["worker-thread"], function(WorkerThreadModule) {
// bla bla bla
let workerThread = new WorkerThreadModule.WorkerThread();
});
