Access

This is a private GitHub package published under the EQTY Lab organization. Make sure your npm or GitHub account has permission to access this package.

1. Authenticate with GitHub Packages

You will need a Personal Access Token (PAT) with at least the read:packages scope.

Create one at: https://github.com/settings/tokens

2. Add your GitHub token to npm

Add your token to npm config so it can authenticate to GitHub’s registry.

Option A — via npm CLI (recommended):

npm config set //npm.pkg.github.com/:_authToken=YOUR_GITHUB_TOKEN

Option B — via .npmrc file:

Create or edit a .npmrc file in your project root and add:

@eqtylab:registry=https://npm.pkg.github.com
//npm.pkg.github.com/:_authToken=YOUR_GITHUB_TOKEN

3. Verify access

Run this to check if you can access the package:

npm view @eqtylab/equality

If that command returns package details, you’re good to go.

4. Troubleshooting

If you run into a 404 or ERR_PNPM_FETCH_404 error:

  • Double-check your GitHub token includes the read:packages permission.
  • Make sure your .npmrc file is in the same directory where you’re installing.
  • Confirm the registry line points to https://npm.pkg.github.com.
  • If you’re in a monorepo, also add the .npmrc file to the repo root.
  • Try clearing the npm cache:
npm cache clean --force
