cra-monorepo
This is an example of creating a monorepo using create-react-app.
It does not work currently, See CRA issue #3676.
Repo Structure
cra-monorepo
|--- myapp (CRA)
| `--- src
| `--- components
| `--- Home.js
`--- shared (shared components)
`--- components
`--- Profile.js
The .env
file under myapp has been set up to import source from ./src
and ../shared
:
NODE_PATH=./src:../shared
Issue Before Ejecting
cd myapp
yarn
yarn start
You will see the following error:
Failed to compile.
../shared/components/Profile.js
Module parse failed: Unexpected token (5:16)
You may need an appropriate loader to handle this file type.
| class Profile extends React.Component {
| render() {
| return (<div>Profile</div>);
| }
| }
Basically CRA fails to recognize Profile.js
as a JSX file.
If I remove the Profile
component from myapp/src/App.js
, the app works correctly, demonstrating that local components such as Home
work perfectly. It's only the components in the shared
folder that have the problem.
Issue After Ejecting
To fix the issue. I have ejected.
- I added an
appShared
export in paths. - I added
paths.appShared
to the webpack config so that the jsx files are passed through eslint and babel. See here and here.
This allowed the build to progress a bit further, but now something else is tripping up on shared/components/Profile.js
, not recognizing it as a jsx file. Here's the error:
../shared/components/Profile.js
Syntax error: Unexpected token (5:16)

> 5 | return (<div>Profile</div>);
