GitHub Release Monitor
Bash monitor for GitHub releases, with Telegram notifications and SOCKS5 proxy support.
Requirements
- Bash 4+
- curl with SOCKS5 support
- jq
- flock (util-linux)
- mktemp (coreutils)
Debian:
sudo apt-get install curl jq ca-certificates util-linux
Setup
cp .env.example .env
chmod 600 .env
chmod +x monitor.sh
Set TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID in .env. GITHUB_TOKEN is optional for public repositories. SOCKS5_PROXY can be set to socks5h://127.0.0.1:1080; socks5h resolves DNS through the proxy. The .env file is sourced as Bash: use only trusted local configuration.
Edit repos.json to select GitHub repositories. Initial test set: Lychee, Firefly III and Memos.
Commands
./monitor.sh --test-telegram
./monitor.sh --dry-run --verbose
./monitor.sh --init
./monitor.sh
./monitor.sh --include-prereleases
--test-telegram sends one Telegram test message without querying GitHub or accessing state.json/repos.json.
--init records current releases without notifications; it replaces existing baselines. Use only for first initialization or an intentional reset. Normal first run also initializes missing repositories silently.
--dry-run queries GitHub and displays pending notifications without sending or changing state. On a repository without baseline it prints its current release tags.
--include-prereleases overrides INCLUDE_PRERELEASES=false. To track prereleases continuously, set INCLUDE_PRERELEASES=true in .env.
State is written atomically after each successful Telegram notification. If Telegram accepted a message but its response was lost, a duplicate may be sent next time. The state contains release IDs and grows over time. A bounded GitHub pagination window (GITHUB_PER_PAGE * GITHUB_MAX_PAGES) may miss releases if more are published between checks. For small projects and daily checks this is generally sufficient.

Run the monitor under a dedicated user where possible. Keep .env private and do not commit it. Use ./monitor.sh --test-telegram to verify Telegram and proxy connectivity.
