我可以制作一个包含多个可以在消费应用程序中独立导入的 React 组件的 NPM 包吗?
我有一个带有两个可重用 React 组件的 NPM 包。一个组件导入一个沉重/相当大的第 3 方库。其他组件不导入此第 3 方库。
我希望能够在使用应用程序时使用这些组件,并且如果我已导入可重用组件来导入重型库,则仅在我的应用程序包中包含重型 3rd 方库。
如果我不使用 HeavyWeight 组件,有没有办法设置我的可重用包,它不会在我的应用程序包中包含“重库”?
// My NPM package
// components/HeavyWeight.js
import React from 'react';
import heavyLibrary from 'heavy-library'; // This component imports a very heavy library
const HeavyWeight = () => {
const a = heavyFunction();
return (
<div>
{a}
</div>
);
}
export default HeavyWeight;
// components/LightWeight.js
import React from 'react';
const LightWeight = () => {
return (
<div>
I'm light weight.
</div>
);
}
export default LightWeight;
// index.js
import HeavyWeight from './components/HeavyWeight';
import LightWeight from './components/LightWeight';
export { HeavyWeight, LightWeight};
// webpack.config.js
// ...
module.exports = {
//...
externals: {
heavy-library: 'heavy-library'
}
};
// Two of my apps using my reusable components
// appA.js
// Bundling this app should include 'heavy-library' in final webpack bundle
import { HeavyWeight } from 'reusable-package';
// appB.js
// Bundling this app should not include 'heavy-library' in final webpack bundle
import { LIghtWeight } from 'reusable-package';
