⚠️ UPDATE: Jan 2021 - THIS IS NO LONGER MAINTAINED

This repository tried to support adding a comment. There is a much better support from GitHub in https://github.com/actions/github-script.

You can use the github-script with Comvent (https://github.com/rytswd/comvent) to provide ChatBot like support.

Comvent is still being supported.

Respost - Response Post

WHAT: Send Response from GitHub Actions

Simple HTTP POST to write to the Issue and PR.

HOW: Example - Issue Creation + Bot-like Response

WARNING: I have edited the above recording, it was originally around 90 sec.
NOTE: comvent is used to provide bot-like comment parsing.

HOW: Example - Above, with YAML

name: Respost - Write comment to new Issue event
on: issues

jobs:
  comment:
    runs-on: ubuntu-latest
    steps:
      - uses: rytswd/respost@v0.1.0
        with:
          title: Respost Custom Title from step 1, for Issue
          body: "Hello, World! Respost is here, making your GitHub Actions workflow even easier!"
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

This is all you need to automatically drop a comment when a new issue is created.

You can find more examples in this repo's .github/workflows/.

WHY: Simple and Cheap

GitHub Actions can be defined either in JavaScript or Docker container.

Docker container allows full segregation and secure setup, but it takes about ~10sec to build and start up.
When you wish to use GitHub Actions on frequently used events such as PR and Issue Comments, this can easily add up.

TypeScript can work seamlessly with JSON object, and axios provides easy HTTP POST handling.
