# Publish installable pull-request package previews before release with pkg.pr.new

Use pkg.pr.new when an agent needs an installable preview build from a pull request so reviewers can test a package before the maintainer cuts a real npm release.

## Prerequisites

A GitHub repository with Actions enabled, the pkg.pr.new GitHub App installed, Node.js/npm for the package build, and a package that can be built from CI.

## Installation

Use the upstream install or setup path that matches your environment:
- npm i https://pkg.pr.new/tinylibs/tinybench/tinybench@a832a55
- Make sure it's installed on the repository before trying to publish a package. To read about the permissions the app needs, check [#305](https://github.com/stackblitz-labs/pkg.pr.new/issues/305).
- npm install --save-dev pkg-pr-new
- pnpm exec pkg-pr-new publish './packages/A' './packages/B' # or pnpm exec pkg-pr-new publish './packages/*'

Requirements and caveats from upstream:
- uses: actions/setup-node@v4
- node-version: 20

Basic usage or getting-started notes:
- First [install the GitHub Application](https://github.com/apps/pkg-pr-new).
- [!IMPORTANT]
- After installing on your repository, run pkg-pr-new from your lockfile in workflows (for example with pnpm exec pkg-pr-new publish) to get continuous releases.
