如何在反应构建中禁用Uglify

Question

I tried to use Y.js (Yjs) npm package and it works in npm start but not npm run build because Uglify doesn't support ES6. So I downloaded the release of that package and include it directly. But my reactjs npm run build is still complaining about Uglify.

 Creating an optimized production build... Failed to compile. static/js/main.3d2ecf94.js from UglifyJs SyntaxError: Unexpected token: name (YArray) [./src/Pages/Collaborative/y-array/y-array.es6:12,0] 

and my webpack.config.js looks like this:

 var path = require('path'); module.exports = { entry: path.join(__dirname, 'public', 'quickstart.js'), output: { path: '/', filename: 'bundle.js' }, module: { loaders: [ { test: /.jsx?$/, loader: 'babel-loader', exclude: /node_modules/, query: { presets: ["react", "es2016", "stage-2"] } }, { test: /\\.css$/, loader: "style-loader!css-loader" } ] } } 

How can I disable Uglify in my webpack? Which line determines that it has to Uglify in building process?

Actually yea I think it uses react-script. Is there anything I can do to alter that?

Answer 1

If you look at what npm run build does, it actually runs another script, react-scripts build . Your project is bootstrapped with create-react-app , correct?

As you can see in the package.json , you also have access to a script called eject .

Running npm run eject will allow you to remove the app from the preconfigured workflow ( webpack , babel , etc ) and let you modify the workflow as you see fit.

With access to the configuration files, you can add, for example, the babel uglify plugin .

But be careful, there is a trade-off. As the docs mention

If your project needs more customization, you can "eject" and customize it, but then you will need to maintain this configuration.
