class-validator VS good-first-issue

You can learn more from the documentation here.

This is the request body when creating a new task. The IsString decorator provided by class-validator rejects all types other than strings, including undefined or null. The task name value object does not consider the possibility of values other than strings.

In this class, we are using the famous class-validator to decorate our request parameters. This way it is more clear how we are going to use our request object and everything.

We add validation using https://github.com/typestack/class-validator.

I will make sure we get this documented.

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.

Start by installing the class-transformer and class-validator packages for dto validation (see more in the docs), sharp for image optimization, and the S3 client packages.

The description of the request body model in NestJS is similar to the description of Ditsmod models, but NestJS uses decorators provided by the utility class-validator. In NestJS, it is customary to name the request body model with the ending *Dto (this is an abbreviation of Data transfer object):

You could use Zod or Superstruct to validate the types of values, or use typestack/class-validator if it makes sense.

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.

https://goodfirstissue.dev might be a great place to check :)

Another source is mentor feedback, somebody who tells you he thinks you can do it, some projects seem more open to new contributors, search good first issue, if you will open an issue saying you are willing to commit to say 1-2h a week for a year i believe you will get help.

Good First Issue

Good First Issue website curates the issues with good first issue tag from various open-source projects and displays them with a nice and clean UI.

If that doesn't work, get on https://socialcoder.org/Home/Index or contribute to an open source project - https://goodfirstissue.dev/.

You can also use websites like up-for-grabs, goodfirstissue, or CodeTriage to find projects with open issues. Find one that looks easy or interesting to you and comment on it, asking if you can take a shot at it.
