learn-go-with-tests VS validator

There are not particularly bad parts. Overall the book is well written and organized. Moreover, Since it is also an open-source material, many readers have contributed to the contents of the book(including a few of mine :)). I hope there are more books like this for other languages such as Rust or Python.

i.e using this free open source book Learn Gol with Tests

I really like Learn Go with tests. Not only is it a neat resource for learning Go, but it's great for getting a feeling for TDD.

You can try viewing it on github instead https://github.com/quii/learn-go-with-tests/blob/main/scaling-acceptance-tests.md

If you already know php and want to get professional in go, i suggest you take a look at https://github.com/quii/learn-go-with-tests

Hi, author here.

The project is open-source (https://github.com/quii/learn-go-with-tests) so there's a few options available to you.

In releases, you'll find PDFs and epubs, I'm pretty sure most epub readers will let you use a dark mode. Or you can just read the markdown files on GitHub, which also supports it.

I know there are better packages like go-playground/validator that I could use it but I wanted to suffer a bit before using these already working packages :)

I'm aware of this as well as go(lang)'s https://github.com/go-playground/validator, so you are right, I'm wondering about a more implicit validator like what Pydantic does when a value is assigned, versus an explicit call to validate().

Why not use popular Go libraries like Package validator or govalidator? While both libraries are well-known, validatorgo focuses on standalone string validation and provides an extensive collection of customizable validators inspired by validator.js, which neither of these Go libraries fully implement.

Request data is validated using Package validator. Check the documentation for more details on how to write validations.

In the Golang implementation, the input for the usecase already is the validator. Here we are using go-playground/validator to do this validations, and the implementation for this is simply usign the tag validate.

The nao1215/csv package was developed with inspiration from go-playground/validator and shogo82148/go-header-csv. I would like to express my gratitude here.
