Configure environment and secrets for NestJS

Summary

Configuration and secrets for a NestJS app on Ample. Verified on NestJS: an --env value delivered encrypted and reported as present without being echoed (secret=set). Build and start: npm install, nest build (TypeScript) then node dist/main.js on the node-22 template.

Infrastructure requirements

• Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)

Prerequisites

• A NestJS project (npm install, nest build (TypeScript) then node dist/main.js on the node-22 template)
• An Ample account token with servers:write

Exact tested configuration

• template: node-22
• runtime: node
• size: s-1vcpu-1gb
• install: npm install
• build: npm run build --if-present
• start: npm run start

Steps

1. Build and start. npm install, nest build (TypeScript) then node dist/main.js on the node-22 template; the server must bind 0.0.0.0 on PORT.
2. Pass values on deploy. Use --env KEY=value (repeatable) or --env-file; values are encrypted at rest and reused on redeploys. Declare names only in ample.toml.

   ample deploy . --name <app-name> --public --env MY_SECRET=...

3. Verify. Fetch the live URL and /p/configuration-secrets on the example; on failure read the build and runtime logs.

   ample logs <deployment_id> --kind build

Tested examples

• NestJS pattern fixture (tests/deploy-canaries/nestjs-patterns): Verified configuration and secrets on NestJS.

Success checks

• app responds on its public URL (/ on the live URL, expect ample canary nestjs patterns)
• configuration-secrets check from the example (/p/configuration-secrets on the live URL, expect see the pattern fixture checks)

Limitations

• Verified on the node-22 template at s-1vcpu-1gb; other sizes and NestJS major versions are not verified.
• Region, compliance attestations and request-duration limits are unknown and not claimed.

Cost estimate

Estimated 5.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

• app server x1 s-1vcpu-1gb: 5.00 USD

Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.
