CLI + GitHub action to combine dependabot PRs on GitHub repositories.

The CLI is published on npm so it can be run with all of the usual node methods. The easiest is npx:

$ npx combine-dependabot-prs me/my-repo

Substitute me & my-repo with the owner & repo you're targeting.

You can also install it globally:

$ npm i -g combine-dependabot-prs
$ combine-dependabot-prs me/my-repo

You'll need to create a Personal Access Token to use with the CLI. You can provide it one of three ways:

1. With --github-token flag
2. With GITHUB_TOKEN env var
3. Via prompt at runtime

Create a new action in your repo by creating a file called .github/workflows/combine.yml. In that file drop this contents:

name: "Combine Dependabot PRs"
on:
  workflow_dispatch:

jobs:
  combine-prs:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2.3.3
      - uses: maadhattah/combine-dependabot-prs@main
        with:
          branchPrefix: "dependabot"
          mustBeGreen: true
          combineBranchName: "combined-prs"
          includeLabel: ""
          ignoreLabel: "nocombine"
          baseBranch: "main"
          openPR: true
          allowSkipped: false

These are the defaults, and any or all can be customized or omitted.

Once you've added this workflow to the repository (you'll need to merge it into your main branch first), go to your "Actions" tab, and click the newly added workflow. Then click "Run workflow", and the green "Run workflow" button to start the job. When the workflow succeeds, a new PR will be opened in your repository with the combined dependency bumps.
