Air Reproducible Examples

This repo collects minimal projects that reproduce bugs when running apps with Air. If you hit an Air bug, add the smallest repro you can here and open a PR so others can run it quickly.

Quick start

• Install Go (1.21+ recommended) and Air: go install github.com/air-verse/air@latest.
• Pick a sample directory, cd into it, and run air.
• Hit the route noted below; stop with Ctrl+C when you are done.

Current samples

• air-proxy-timeout/: Delays startup by one second so Air's proxy on :8888 times out while the app comes up on :7777 (reproduces air-verse/air#732).
• proxy-reload-timing-issue-656/: Browser reload triggered immediately when process starts, before app is ready to accept connections on :8080; Air's proxy on :8081 shows "unable to reach app" error (reproduces air-verse/air#656).
• race-condition-issue-784/: Race condition where Build B cancels itself when triggered during Build A, leaving outdated binary running (reproduces air-verse/air#784).
• send-interrupt-delay-issue-671/: When send_interrupt = true, Air always waits full kill_delay even if process exits gracefully in milliseconds, wasting ~1.9s per reload; server on :9090 (reproduces air-verse/air#671).
• sse-chunking-issue/: Air's proxy buffers and repackages Server-Sent Events into larger chunks instead of forwarding them immediately; direct on :3002, proxy on :3082 (reproduces air-verse/air#791).
• "with space"/: Gin app kept in a path containing a space to check watcher/build behavior; air serves /ping and /index on :8080.
• with-template/: Gin app rendering templates (LoadHTMLGlob) with a couple nested packages to see how template changes are picked up; air serves /ping and /index on :8080.

Add a new reproduction

1. Create a new folder named after the bug or upstream issue; keep code and dependencies minimal.
2. Include a .air.toml, go.mod, and a short README inside that folder explaining expected vs actual behavior, ports used, and exact steps to trigger the bug.
3. Make sure air runs cleanly from that folder (the shared tmp/ patterns are already gitignored).
4. Update this README with a one-line description of your sample and open a PR linking to the upstream Air issue you are reproducing.
