Project details

You get a fully maintainable, decoupled REST backend with NodeJS, generated automatically from an OpenAPI yaml or json descriptor. If you don't have it, I'll write it for you, based on your API description / requirement.
You're not locked in by this technology, you can remove it at any point from your project and you still have your runtime code. Or you can use it throughout the development cycle. Each time you change anything in your API, you run the generator and get the corresponding runtime code.
