如何处理JavaScript套件中的版权声明?

当我发现我的捆绑包中有一个Microsoft版权声明时,我正在编写几个小型演示向同事解释装饰器(以打字稿形式),这种声明使我的整个文件对所有人免费(由MS制作)。

应该如何有效地处理此问题(如果我创建了一些非免费的内容)?

我使用Typescript 3.1进行编译和汇总以进行捆绑。

代码:

import { isNotUndefined, isNotNullOrUndefined } from "goodcore/Test";

function deprecated<S>(instead?: string, message?: string) {
    // Logic removed for brevity...
}

class Car {
    @deprecated()
    public turnIgnitionKey() {
        this.start();
    }
    public pressStartButton() {
        this.start();
    }
    private start() {
        console.log("Running!");
    }
}

let car = new Car();
car.turnIgnitionKey();
car.pressStartButton();

和包开始(最后一个功能是我的,而以前的功能是MS):

'use strict';

function __decorate(decorators, target, key, desc) {
    var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
    if (typeof Reflect === "object" && typeof Reflect.decorate === "function") r = Reflect.decorate(decorators, target, key, desc);

function __metadata(metadataKey, metadataValue) {
    if (typeof Reflect === "object" && typeof Reflect.metadata === "function") return Reflect.metadata(metadataKey, metadataValue);
}

function isNullOrUndefined(arg) {
    return arg === undefined || arg === null;
}

您可能会在创建的每个JavaScript文件上方添加自己的自定义许可证,因此将其捆绑在一起时,您的许可证文件应显示在JS代码上方。

/*! *****************************************************************************

<Custom license text here>
***************************************************************************** */

// Your JS code below your custom license

Rollup将所需的所有内容捆绑到输出文件中。您看到的是tslib模块中的Typescript助手。

您可以使用tslib库导入来替换该代码(并摆脱MS许可证)。

添加到您的rollup.config.js以下设置:external: ["tslib"]。不幸的是,您需要在项目的依赖项(或peerDependencies)中添加tslib模块。

检查以下对话以了解更多详细信息: https://github.com/ezolenko/rollup-plugin-typescript2/issues/58(关于外部设置)

https://github.com/ReactiveX/rxjs/issues/2436#issuecomment-371585945(关于依赖性vs peerDependency的问题)

我在汇总配置中添加了rollup-plugin-terser,并将注释设置为false,因此所有注释均被删除。

...
import { terser } from 'rollup-plugin-terser';
...
plugins: [
    ...
    terser({ format: { comments: false } }),
    ...
]
