piscina VS vitest

Workers multi-threading via Tinypool (a lightweight fork of Piscina)

For threading best to use piscina and for clustering best to use pm2 which does not even need one line of code change in Node.js code.

We used piscina at it was quite good: https://github.com/piscinajs/piscina

We used Benchmark.js for benchmarking and piscina as a pool for worker threads. benchmark.js was used to run the same code in 2 scenarios - one using a single thread and one using the piscina pool. The degree of parallelism was passed to the program via an environment variable. The test code is present in worker.js in both the cases.

One other thing...this passed by in my feeds last week, I’m not an expert in web workers or browser threads etc, but it seems like it might be relevant, so sharing it just in case:

“A fast, efficient Node.js Worker Thread Pool implementation”

This is by no means a complete list of what piscina can do.... checkout the official docs here.

Using something like Vitest, Jest, or Mocha didn't work because:

However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

Next we’ll install Vitest and happy-dom to the project by running:

vitest is a testing framework similar to jest that integrates well with projects using Vite. It allows us to reuse plugins and configurations already set up in the vite.config.ts, making the test setup process easier.

For more detailed information on Vitest, refer to the official documentation. fficient Testing in Your React Projects with Vitest.

Vitest

Are you looking to migrate from Jest to Vitest for your React application? Look no further.

In addition to those tools, a new testing framework has emerged named Vitest. Vitest is built on top of Vite and has many exciting features to keep improving the overall developer experience for writing tests. This post shows you how to set up Vitest in your existing Angular project.
