sha-256-js VS testing-nestjs

The wikipedia article spells it out pretty clearly, and the pseudo-code is easily translated into any language, here it is in JavaScript if anyone is interested:

sha-256: https://github.com/jeffallen6767/sha-256-js/blob/master/src/...

Once you understand the concept that most of these algos are simply dividing the input into computer-friendly sized blocks and then stacking and manipulating these bits in 3d space like a rubics cube, then the whole thing becomes a bit easier to understand.

Here's a few more for comparison:

sha-1: https://github.com/jeffallen6767/sha-1-js/blob/master/src/sh...

md5: https://github.com/jeffallen6767/md5-js/blob/master/src/md5....

keccak: https://github.com/jeffallen6767/keccak-p-js/blob/master/src...

side note, I also ended-up implementing the keccak algo in c for open cl usage, because I wanted to see if I could use it in parallel on my graphics card from nodejs ( spoiler: it's indeed possible ):

Please forgive my terrible programming style, this was done years ago...

Here's my SHA-256 hashing algo implemented in JavaScript for NodeJS.

To echo the other's here, Nx has been an amazing dev experience for me! I use it for ogma, for nest-commander, testing-nestjs, and for nest-samples and @nest-lab/, all using pnpm as a package manager.

The prisma sample app in the testing-nestjs repository does a great job on showing how to do testing a NestJS app with Prisma.

Example https://github.com/jmcdo29/testing-nestjs/blob/8519ae7043d1dde5ae12a5d8f8ab02ea3c3c2fcf/apps/complex-sample/src/cat/cat.interceptor.spec.ts

Question: for your e2e tests will you be using something like supertestto send the gql request? And if so, could I suggest you look at pactum which (in my opinion) has a stronger API and better gql support. I've got an example here if you need it

Test files usually shouldn't be too large. You should just need a simple mock for each injected dependency for the service. You can see a lot of examples I have here. If you could show your test file it may help us figure out why it might be really large.

Then there's also a @nestjs/testing package that can be used for overriding these injections during tests to make for super easy unit testing (in my opinion) and a large repo of examples here.
