We run our own products on the same stack we recommend. Growth is three apps behind one account:
- Target — goal trees, with progress rolling up from sub-goals
- Recorder — time-series records and charts, one tag at a time
- Stopwatch — measure something, then file it straight into Recorder
- API Specs — OpenAPI reference and integration recipes for the public APIs
- @nasebanal/cli — a gcloud-style CLI, generated from those specs
- @nasebanal/sdk — typed client library, no runtime dependencies
- nb-quickstarts — Docker + Makefile quickstarts for Kafka, Consul and Locust
Contract first. Every API is defined as an OpenAPI spec, published as a versioned package, and only then implemented:
- consumers build against a stub generated from the spec, so frontend work never waits on the API
- contract tests run in CI on both sides, so drift fails a pull request instead of production
- breaking changes are expressed by URL versioning, additively — existing paths keep working
TypeScript end to end, running on Cloudflare Workers with D1 and R2, with repository and infrastructure settings kept in Terraform.
