🤖 denopendabot

Denopendabot is a GitHub App, GitHub Action, and Deno module to keep the dependencies of your Deno projects up-to-date.

Obviously inspired by Dependabot, and making up for their missing support for Deno.

Warning
Still under development. Many bugs might remain. Any breaking changes may be introduced on each Feature release.

Update Deno modules

import $ from "https://deno.land/x/dax@0.14.0/mod.ts";

- import $ from "https://deno.land/x/dax@0.14.0/mod.ts";
+ import $ from "https://deno.land/x/dax@0.15.0/mod.ts";

Denopendabot takes advantage of the core engine of udd, one of the most widely used module update libraries for Deno, which supports many registry domains.

Update GitHub repositories

- uses: denoland/setup-deno@v1
  with:
    deno-version: v1.26.0 # @denopendabot denoland/deno

-   deno-version: v1.26.0 # @denopendabot denoland/deno
+   deno-version: v1.26.1 # @denopendabot denoland/deno

Denopendabot can also update release versions of GitHub repositories, specified by comments of @denopendabot {owner}/{repo}.

🚀 Getting started

GitHub App

The easiest way to use Denopendabot is to install the GitHub App and create a workflow to run it:

name: Denopendabot
on:
  workflow_dispatch:
  schedule:
    - cron: "0 0 * * *" # modify to your convenient time
jobs:
  update:
    name: Run
    runs-on: ubuntu-latest
    steps:
      - uses: hasundue/denopendabot@0.9.0 # @denopendabot hasundue/denopendabot
        mode: app
        auto-merge: all # optional

This workflow dispatches a denopendabot-run repository event, and an instance of the app receives it to perform the procedure on Deno Deploy.

See the next section for the details of the workflow.

Warning
Denopendabot requires write access to your workflows, which technically enables the bot to perform script injection on your repository. Install the app only if you are sure that it is reliable.

GitHub Action

If you want Denopendabot to run in an environment under your control for security reasons, you can use our GitHub Action.

The action needs a GitHub access token authorized to run workflows. secrets.GITHUB_TOKEN is used by default and it works fine in most cases.

If you want to update workflow files (.github/workflows/*.yml), it also needs a private access token with the workflow scope. In the examples below, we assume the token is added in repository secrets as GH_TOKEN.

name: Denopendabot
on:
  workflow_dispatch:
  schedule:
    - cron: "0 0 * * *" # modify to your convenient time
jobs:
  update:
    name: Update
    runs-on: ubuntu-latest
    steps:
      - uses: hasundue/denopendabot@0.9.0 # @denopendabot hasundue/denopendabot
        with:
          user-token: ${{ secrets.GH_TOKEN }}

See action.yml for other options.
