我正在尝试在web worker中使用typescript中的外部模块并遇到问题。测试示例的所有代码都在www.windward.net/temp/WebWorkerRequireJs.zip(下面列出的关键代码)。
我想要的打字稿(这在主线程中工作正常:
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失败,因为未定义define:
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
这不起作用并给出了错误:
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“define”切换为“require”,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
这导致了一个问题 - 我如何获得打字稿来生成它以便它运行。解决方案是设置一个主要的javascript文件,然后调用typescript部分的初始Web工作者应用程序?如果是这样,我该如何设置呢?
或者解决方法是以某种方式告诉typescript编译器从define更改为require并插入importScripts()?
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。这有importScripts()和主要的typescript类的require。您创建该类,它从那里运行。在那一点上,“导入”的打字稿“定义”所有作品。到目前为止......
答案 0 :(得分:0)
工作程序文件不会被AMD加载程序加载,并且将由浏览器加载。所以你需要打破AMD代码生成并自己使用原始的“require”调用。
