Benchmarks for "Hello, World!". Fastify slowed down a bit, Ditsmod and Restify sped up.
My last measurements were when Fastify was v3.25, Restify v8.6 and Ditsmod v2.0. From that moment on, although Fastify remained in the lead, other frameworks came quite close to its results.

How can I declare, integrate a JSON (or similar type that is supposed to be data sent from a server) file into my Angular app, and use it;s data to display the array of Devices within it?
Also OP can check out class-transformer + class-validator if he want to properly instantiate objects and validate them with precise and verbose output of potential format errors. OP can even go the god tier way by setting up a custom RxJS operator that does that for him easily.

I found 10,000x faster TypeScript validator library
Also, title of before article was I made 1,000x faster TypeScript validator library, but today's benchmark is showing that typescript-json is maximum 6,500x times faster. It's just because I added a new library class-validator in the benchmark and it is much slower than previous zod. Of course, I've continuously tuned the performance, but it just improved the performance about 2x times only.
