Node.js is one of the environments I utilize most frequently in applications when an endpoint or API is needed (unless I opt for python, which typically would only be chosen if the task calls for certain requirements like machine learning). I have deployed many express applications with REST, GraphQL, and work-queue driven or imperative APIs exposed to other services. Typically, statelessness is a driving goal wherever possible, and I prefer JWTs alongside clean, versioned routing conventions.

Today I typically begin any new node project with typescript, as I do on the front-end, and am adept at writing intelligent unit tests.

Other uses of Node.js in my prior projects include isomorphic apps with server-side rendering in React, building ORM-like tools to move between massive university relational databases and clean objects, and proxying or wrapping other services like elasticsearch for exposed APIs. I have also developed web assembly code, typically in rust, to run equivalently and efficiently as part of an isomorphic pipeline for the client and Node.js on the server.
