This github action is built to keep your PR's up to date.

On a push to your main branch, this will find all open PR's with a particular tag and merge the main branch (name is configurable) into the PR's.

This can be useful for a large team with a long(ish) build time to avoid developers from having to keep up with multiple pushes to the main branch.

With the label specification, it is an opt-in action so that developers who prefer to manage their own branches will be unaffected.

Usage

Assuming you want to auto merge a branch called development into all PR's with the label automerge development, add a workflow file to your .github/workflows with the following:

name: Merge main into PR branches labeled "automerge development"

on:
  push:
    branches:
      - development
jobs:
  get_pull_requests:
    runs-on: ubuntu-latest
    name: Stay up to date with development
    steps:
      - uses: rcode5/keep-prs-up-to-date@master
        with:
          token: ${{github.token}}
          default_branch: development
          labels: "automerge main"

You can also force this auto-merge on every pr with the all parameter.

name: Merge main into PR branches labeled "automerge development"

on:
  push:
    branches:
      - development
jobs:
  get_pull_requests:
    runs-on: ubuntu-latest
    name: Stay up to date with development
    steps:
      - uses: rcode5/keep-prs-up-to-date@master
        with:
          token: ${{github.token}}
          default_branch: development
          all: true

Development

Edit the index.js and run yarn build to build the dist version.
