How do I use multiple npm registries in Yarn?

Question

I\'m trying to setup Yarn 0.17.9 in our environment but I have a problem with our registry. We are currently using two registries, official npmjs and our own registry on interna

Answer 1

You can make a .yarnrc file in the root of the project and write this line in that file:

registry "https://registry.npmjs.org/"

This will act as a project specific repository.

Answer 2

Yarn doesn't have support --registry flag as npm but you can set up your registry in .yarnrc

If your .yarnrc is being ignored it can be copied out of the ~/.yarnrc using:

yarn config set registry http://registry.com/registry//

Answer 3

You can try set different registry in .npmrc and .yarnrc.

So for example: In .npmrc:

registry=https://yourcompany/
virtual/:_authToken=credentials
always-auth=true

always-auth=true needs to be the very last line in the file

And in .yarnrc:

registry "https://registry.yarnpkg.com"

Then yarn add/npm install + private-pakage/public-packge will work.
