javascript - 使用 webpack 时如何不解决需求

Question

如何强制 webpack 不解析节点模块中的 require 语句？

在下面的单元测试示例中，我希望 webpack 解析 require('./element.js') 但只是跳过 require('chai') .

如何做到这一点？

index.js:

'use strict';

const assert = require('chai').assert;
const element = require('./element.js');

describe('element.create', function () {
    jsdom();

    it('creates a div', function () {
        var div = document.createElement(element.create());
        assert.strictEqual(div.nodeName, 'DIV');
    });
});

运行:

webpack index.js index-bundle.js
mocha index-bundle.js

我想您可能正在寻找 externals

来自文档:

Externals: Specify dependencies that shouldn’t be resolved by webpack, but should become dependencies of the resulting bundle. The kind of the dependency depends on output.libraryTarget.
