Mixing
Rollup with React vendor splitting
0
I'm experimenting with using Rollup as a React toolset. I've got a working prototype when I can use lazy loading in react. I'm just working with just ES6 Modules, I'll integrate SystemJS for older browsers later. My question is regarding the rollup setup. It seems crazy to treat react and react-dom as internal, then have to supply a manualChunk and split them out again.
If I treat them as external and not chunk them I get the following error:
Uncaught (in promise) TypeError: Failed to resolve module specifier "react-dom". Relative references must start with either "/", "./", or "../".
Is there any way to treat react and react-dom as external and reference them from a CDN?
import commonjs from 'rollup-plugin-commonjs';
import nodeResolve from 'rollup-plugin-node-resolve';
import babel from 'rollup-plugin-babel';
import json from 'rollup-plugin-json';

export default {
input: ['src/index.js'],
output: {

},

// Is there any way to avoid this?

'./node_modules/react-dom/index.js': ['render'],
},
}),
nodeResolve(),
babel({
exclude: 'node_modules/**',
}),
replace({
'process.env.NODE_ENV': JSON.stringify('development'),
})
],
// If react is treated as external, how can it be loaded into this ESM module from a UMD?
