Project Generation

Verified status as of March 13, 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.
