Express.js development
Express APIs from our UK IT agency: Node services with auth, tests and notes the next engineer can use.
SJ Technologies is a UK IT agency. Express.js development is Node APIs and the middleware around them: auth, validation, the proxy to a system you already run. We use Express when a small, explicit service is enough. If a heavier framework or .NET is the cleaner fit for the estate, we say so.
Express APIs with a written contract for paths, auth and errors. Tests for the cases that fail in production. Hosting and secrets treated as part of the same job. Documentation the next Node engineer can pick up.
