Verified status as of March 28, 2026.

Quick View

• Complexity: Beginner
• Typical time: 5-10 minutes
• Outcome: reproducible starter project with next steps and validation commands

Generate a Starter

mkdir my-fastfn-app
cd my-fastfn-app
fastfn init hello -t node
fastfn dev

Then validate:

curl -sS 'http://127.0.0.1:8080/hello'
curl -sS 'http://127.0.0.1:8080/openapi.json' | jq '.info'

What init Sets Up

• project config (fastfn.json)
• functions root
• runtime templates
• discovery-compatible layout

Validation

• new function is discovered automatically
• request returns 200
• OpenAPI includes the new route

Troubleshooting

• If fastfn is missing, install CLI and re-open shell.
• If native mode fails, install host deps or use Docker mode.
