I recently needed a blazing fast concurrent to fetch items from an API. Of course, I could use a combination of async-awaits and some cryptic code with promises and so I took a stab at doing this in rxjs.

import { Observable } from 'rxjs';

export function doPaginate<T>(
  fetchPage: (page: number) => Promise<{ totalRows: number; resultItems: T[] }>,
): Observable<T> {

The following is an altenative way to do dependency analysis for Node projects but using SQL.

Note

This project is not intended to be comprehensive by any means but is simply a demonstration of what is possible.

The approach centers around reading the dependency tree using the the output of the npm ls command and loading it into SQLite.

I recently needed to use a Node-based Lambda where it depended on an NPM module.

https://github.com/mridang/serverless-servestatic-plugin/blob/a9e8f3c677e60be2065e84ded8cc5fe1da72e813/src/lambda.js#L7-L10

I didn't wan't to begin using a bundler, switch runtimes or do any workarounds. I just needed to get this custom resource up and running.

Note

I'm not sure whether this whole approach is overkill and could be better accomplished by using URL-based imports.
