Upgrading TypeORM with jscodeshift — TypeORM is an ORM that supports both Data Mapper and Active Record patterns, and last year it introduced some breaking changes that left the author of this post facing a lot of updates to be made. What to do? Write a ‘codemod’ to automate the job! Even if you don’t use TypeORM, this post might give you some ideas for other places to use a code rewriting approach.

Useful Functions for a (Deno) HTTP Server — One way to think about an HTTP-based service is functionally, with requests going in, being processed, and a response heading out. The author explores Deno’s new Deno.serve function and how both it and the /x/http_fns functions can provide a more functional approach to common HTTP tasks. Possible food for thought even in Node with things like Hono picking up pace.

YouTube.js 5.5: A Wrapper Around YouTube's Private 'InnerTube' API — A year ago I wondered if this would continue to work, but apparently it does, and it uses the same behind the scenes API as official YouTube clients (you've gotta love the name 'inner tube'..).
