Module not found: Can't resolve 'module'

Can’t resolve ‘module’

When linking a dependency locally that uses module-alias, I’m getting the error below:

Module not found: Can't resolve 'module' in '/Users/inje/Docs/repos/setprotocol.js/node_modules/module-alias'

How to Reproduce

1. Have a locally cloned repo of your dependency and build your package.
2. Run yarn link to create your symlinked package
3. In your depender repo, run yarn link my-package-name
4. In the depender repo, run your code yarn start

Extra details

• The dependee library using module-alias is using typescript
• The depender repo is a React app linking the dependee library locally. It’s also using typescript

@Fensterbank Are you sure you are running it using Nodejs? Because some people have problems running it in Meteor or other environments.

I tried to create a simple file with

// test.js
require('module-alias/register')

And calling it with node ./test.js works

Ok I looked into it. It definitely works in pure Node, see proof of concept: https://github.com/Kehrlann/module-alias-yarn-link

No need for module-alias in a TypeScript project, you can use tsconfig’s paths, see: https://blog.joefallon.net/2018/02/using-short-imports-in-typescript/ … you app being React, it will very likely run through a Webpack step, which also have it’s own module-aliasing capabilities: https://webpack.js.org/configuration/resolve/ . I’m no sure module-alias is the right solution for you.
