Deployment - Jelou AI Docs

Deployment flow

When you run jelou functions deploy, the platform:

Reads jelou.json to find the slug and entrypoint
Collects all deployable files from the directory
Displays a summary with names and sizes
Uploads the files and runs the deployment
Renames your entrypoint to user-function.ts
Generates a main.ts wrapper that imports your code and starts the server
Injects your secrets as environment variables

jelou functions deploy
# ▸ Files: index.ts (1.2 KB), helpers.ts (800 B), jelou.json (98 B), deno.json (65 B)
# ? Deploy query-customer? (Y/n) y
# ✓ Deployed
# ▸ ID:  dep_abc12345

            JELOU_API_KEY=${{ secrets.JELOU_API_KEY }}

      - name: Deploy
        env:

        run: |
          DEPLOY_URL=$(jelou functions deploy --no-confirm --json | jq -r '.data.url')
          echo "Deployed to $DEPLOY_URL"

Use --json in pipelines to get structured output you can parse with jq. The format is always { "ok": true, "data": ... } on stdout.
