我从打字稿和角度开始,我必须为自定义库创建一个typedefinition。当我运行该应用程序时,我看到我的外部库的javascript存在于资源中并已加载(通过控制台检查),但是当我的打字稿代码调用时,出现此错误:ERROR TypeError: Object(...) is not a function
。似乎我丢失了一些东西,我的index.d.ts与我的index.js位于同一文件夹中,
app.component.html
<!--The content below is only a placeholder and can be replaced.-->
<div style="text-align:center">
<h1>
Welcome to {{ title }}!
</h1>
<input value="open editor" type="button" (click)="openEditor()"/>
<router-outlet></router-outlet>
app.component.ts
import { Component } from '@angular/core';
import {createEditor, Editor} from "editor";
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'my-app';
openEditor() {
console.log(new Editor());
console.log(createEditor());
}
}
package.json
"name": "editor",
"version": "1.0.0",
"description": "editor",
"main":"index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
},
"private": false,
"publishConfig": {
"registry": "http://localhost:4873"
},
"keywords": [
"editor"
],
"devDependencies": {
"css-loader": "^3.0.0",
"csv-loader": "^3.0.2",
"file-loader": "^4.0.0",
"style-loader": "^0.23.1",
"webpack": "^4.33.0",
"webpack-cli": "^3.3.4",
"xml-loader": "^1.2.1"
},
"files": [ "index.js","index.d.ts"]
}
index.js
Editor = function(){
alert("hello");
};
createEditor = function(){
alert("hi");
};
index.d.ts
export function createEditor():void;
export class Editor {
constructor();
}
我简化了代码,因为我看到组件中的角度导入将js正确地放入了dom,但是在调用打字稿代码时失败。因此,我有一种强烈的感觉,我在类型定义中缺少一个要点。这可能是我看不见的愚蠢内容(就像我说的,我是打字稿新手,棱角分明)
欢迎任何想法
预先感谢
答案 0 :(得分:0)
我想我找到了解决方案, 看来问题出在js档案中, js文件缺少导出声明:
module.exports = {createEditor,Editor};
因此,当webpack尝试加载相关导入时,它没有正确加载。
