🪝 GitHub Webhook Script Runner

Run a shell script when you push to a repository - a mini, self-hosted CI/CD 💚

Quickly start up a server that listens to webhooks requests, and run a shell script when you push to your repository on GitHub.

This is most useful when your project is running on a personal VPS (EC2, Droplets, etc.) and you want to relieve yourself of git pulling and npm run building every time.

Setup

Clone this repo or use the template to create a new repo
Setup environment variables: cp .env.example .env:

PORT: The port at which this server will run
WEBHOOK_SECRET: Secret key to encrypt and validate webhook requests. It can be anything, make sure it's secure.
REPO_PATH: Path (to the repository) where you want to run the script
Install dependencies and start the server:
```
npm install
npm start
```
The server is now listening on ${PORT}.
Configure a (sub)domain for this server. Can easily be achieved by using something like Nginx to reverse proxy requests to this server. Let's assume our domain is hooks.example.com.
Setup the repository's webhook on GitHub:
- Go to settings/webhooks in the repository
- Create a new webhook with:
  - Domain: https://hooks.example.com
  - Webhook secret: WEBHOOK_SECRET in the .env file
  - Content type: application/json
  - push type event
🎉 It should be setup now and running! You can view the "Recent deliveries" of the webhook inside the webhook settings on GitHub to check whether you have received a 200 response with Script started.. Debug on your own :P.

Example script

An example script for a basic Node webapp would be:

cd $1                   # cd into the repo's directory
git stash               # stash any changes
git pull origin master  # pull the latest commits
npm install             # install new packages, if any
npm run build           # build production bundles
npm run start           # start the server
