Automate Your Release Announcements: GitHub Release 4 Social Platforms with n8n

#n8n #automation #github #tutorial

The Problem

Building Chrome extensions is one thing. Announcing each release across multiple platforms? Tedious.

So I automated the entire thing with n8n.

The Architecture

GitHub Release Created
        ↓
    Webhook → n8n detects it
        ↓
    Auto-post to:
    ├── Discord (Webhook)
    ├── Bluesky (HTTP Request)
    ├── Dev.to (HTTP Request)
    └── Qiita (HTTP Request)

Setup: Running n8n

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  n8nio/n8n

Exposing n8n with Cloudflare Tunnel

brew install cloudflare/cloudflare/cloudflared
cloudflared tunnel create n8n-tunnel

Config (~/.cloudflared/config.yml):

tunnel: [TUNNEL_ID]
credentials-file: /path/to/credentials.json
ingress:
  - hostname: n8n.yourdomain.com
    service: http://localhost:5678
  - service: http_status:404

The n8n Workflow

Webhook (trigger) → IF (release event?) → Set (format content)
    ├── Discord (Webhook)
    ├── Bluesky (HTTP Request)
    ├── Dev.to (HTTP Request)
    └── Qiita (HTTP Request)

Message Formatting

const releaseName = $json.release.name;
const releaseUrl = $json.release.html_url;
const repoName = $json.repository.name;

return {
  discord: `🚀 **${repoName}** new version!\n${releaseName}\n${releaseUrl}`,
  bluesky: `🚀 ${repoName} new version!\n${releaseName}\n${releaseUrl}`,
  devto: { title: `${repoName} ${releaseName} Released`, body: `New version: ${releaseUrl}` }
};
