Is there any way to use the react-scripts toolchain to build a library? I mean CRA has already done everything for us so why set up rollup separately?

We used CRA for previewing our component but rollup is the one in charge of bundling the library

Thanks for the tutorial I learn much.
You say to do "npm link" the react-library if wanting to test it in some React App locally.
What about this react-npm-library app we build in this tutorial, that host the react-library. Can I do npm link trying the library?

npm link is for testing locally in react app in another directory but since the react-library is already in react-npm-library there is no need to link it. But if you link it will also work

Thanks it's working I publish to npm cool thanks.
But when I npm link I can't compile the exacts same code I think it's missing something in the rollup.config.js look here please:

When I do npm link and start server I get the error:
"Failed to compile.
src\react-library\dist\index.cjs.js
Line 11:261: Expected an assignment or function call and instead saw an expression no-unused-expressions"
Am I suppose to change in the package.json the "main": "dist/index.cjs.js", to this: "main": "src/index.js", ?

I Try that with the npm link in place and then get duplicate react hook error even the react-library use peerDependencies in package.json.
reactjs.org/warnings/invalid-hook-...
Please advice

If anyone else need an answer. Thanks I fixed it reading the docs
reactjs.org/warnings/invalid-hook-...
"This problem can also come up when you use npm link or an equivalent. In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming myapp and mylib are sibling folders, one possible fix is to run npm link ../myapp/node_modules/react from mylib. This should make the library use the application’s React copy.

Hey Beingana,

great Tutorial. Was exactly what I was looking for.

While reading through I noticed this
torch button.jsx
torch index.css

Was this maybe supposed to be
touch button.jsx
touch index.css

Again, thanks for the tutorial

Shouldn't @babel/runtime be included as a peerDependency?

import { terser } from 'rollup-plugin-terser'
what does terser do ??

Collapse

Beingana Jim Junior

Terser is a library that minifies code. This is good for production mode.
If you don't include that plugin then rollup will just compile your code without minifing it.

Is there a simple way to adapt this so that it would work with typescript?
