Support private registry

[dohaicuong]

I've encounter problem when using changesets/action when I'm using the private registry that is not npm.

Upon looking into it the problem seems to coming from the bellow line where it only check for npm registry name.

const authLine = userNpmrcContent.split("\n").find((line) => {
  // check based on https://github.com/npm/cli/blob/8f8f71e4dd5ee66b3b17888faad5a7bf6c657eed/test/lib/adduser.js#L103-L105
  return /^\s*\/\/registry\.npmjs\.org\/:[_-]authToken=/i.test(line);
});

However, beside npm registry, we also have github registry and custom domain gitlab registry.

// npm
//registry.npmjs.org/:_authToken

// github
//npm.pkg.github.com/:_authToken=TOKEN

// custom domain gitlab registry
//code.org.com/packages/npm/:_authToken=

Hence I'm making the change here to address for this problem.
#362

Thank you the team for your work on maintaining this tool!

We need this.

I found a workaround, see this
They set the registry in the script
And authenticate in the workflow
Just tried and it worked

Just configure workflow here, no need to configure scripts. Mainly because changeset will execute npm info to find packages

That workaround (change in the workflow) didn't work for me, the changesets action seems to still overwrite the registry URL. Any chance I can somehow force use the npm.pkg.github.com as a registry?

Update - I found a way to make it work, see an example "release" workflow:

name: Release

on:
  push:
    branches: [main]

permissions:
  contents: write
  packages: write
  pull-requests: write

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Repo setup
        uses: ./.github/actions/repo-setup
        with:
          node-version: '18'
          pnpm-version: '10.10.0'

      - name: Configure npm auth (GitHub Packages)
        shell: bash
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          echo "@your-organization:registry=https://npm.pkg.github.com" > ~/.npmrc
          echo "//npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}" >> ~/.npmrc
          echo "always-auth=true" >> ~/.npmrc

      - name: Build all (if present)
        run: pnpm -r --if-present build

      - name: Version & publish with Changesets
        uses: changesets/action@v1
        with:
          version: pnpm changeset version
          publish: pnpm changeset publish
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The crucial step is Configure npm auth (GitHub Packages) - it creates an .npmrc on the fly with both your custom registry and the auth token settings. The changesets action's code then falls into this case, and later appends this line to the found .npmrc, but it's not a problem - your package(s) will be published to your private registry only.
