How To Build A Complete JSON API In Golang (JWT, Postgres, and Docker) Part 1

Рік тому

In this series, I will teach you how to build a complete industry-ready JSON API project in Golang with JWT authentication, Postgresql, and Docker. We are going to build a bank API and build everything from scratch with only the mandatory packages we actually need. We are also going to write tests for each of our HTTP handlers. If you want to learn Golang or Rust consider subscribing to my channel so you can become a high-value engineer.
This golang tutorial is something for you if you are willing to learn about Golang testing, Golang project structure, and how to use Docker with Golang.
📢 I am also building a Discord community! Feel free to join if you are willing to learn about blockchain, web3, Defi, and quantitative trading. Or just hang out and chat.

i like how you pointed out your usage of a decorator so we can use our handler as an http one without explicitly modifying it. you should keep pointing out useful patterns and such like that, it's very helpful

@user-sd2ry4xy4d 3 місяці тому

Hey Anthony, great great work, I leaned a ton! so thank you :) I have a question tho, you created this interface `Storage` which is passed to the apiServer struct, which is good, but now If I want to add another path say (/products), I will need to create the handle funcs for the product, but then the interface won't work anymore because it's just for the accounts. How create a general interface that can implement all handlefuncs of different business logics Thank you :)

To solve the JSON content format you have to set headers before writing ```go w.Header().Set("Content-Type", "application/json") w.WriteHeader(status) ```

@TedoHamTole Рік тому

Hi Anthony thanks for the video I got one question. You mentioned about circular dependency and no need to create multiple folders/packages. So how do you structure your code is some architecture like (clean, hexagonal) recommended in Go? Or what do you suggest let's say you are handling big project. I really appreciate if you just give me some comment on it. Thanks.

@anthonygg_ Рік тому

Hi! My rule of thumb is to only create packages when you need to, otherwise, just keep things in the root folder. Think about this, if you have 100 files in separate packages or 100 files sitting in the root folders, you will still end up with 100 files right? Also, your program will not run better or faster with more packages. It is just an ancient old scam by people that have no value to bring to the table, so they try to trick you with some "architectural" bullshit. Look at the Redis codebase, for example, that is being used by millions of companies in production. All files live in the src folder. I hope this answer helps you!

can you further explain why you decided to make a wrapper api function? did you just not want to handle the error in each different account handle function and rather handle it in one location?

I just started to learn Golang from a crash course before this, but the naming is confusing to me. There is apiFunc, ApiError and APIServer? the explanation is clear though.

@iamgordonsmith 5 місяців тому

Amazing content this is really useful stuff. I have genuine question regarding makeHTTPHandleFunc - we describe this is a decorator but it was my understanding that with a decorator the interface doesn’t change, only the behaviour, does that make this func more of an adapter? If not, is this concept different in Golang? Thanks!

Maybe “higher order function” would be the correct term. Not 100% sure. I tempt to not focus on terminology but on practical implementations

Why don't you use lowerCamelCase convention for naming methods and vars? I'm completely new to golang and that seems very odd, is there a different convention for go?

@anthonygg_ 7 місяців тому

Lowercase methods are private. Uppercase are public. I know, super awkward

@MaybeBL1TZ Рік тому

i'm new to golang and i didn't understand everything but obviously i'll watch this video 10 times to understand everything but 1 question why you don't use Neovim ?

@anthonygg_ Рік тому

Used vim for years. But VSCode customized is just so good. No hassle spending hours configuring. Syncs with all my machines. But neovim is good, its just not worth my time setting it up again. And vscode scales nice for recording also.

Yes, you are "fast" but that is not always best when you are aiming to teach others and do a tutorial on something, I agree that being fast is amazing (for many things), I am 140-145 wpm typist (you are probably even faster than this) and I am also a vim user for many years. It was really hard to follow this video, had to stop it multiple times. However, good quality video anyways

DO NOT WASTE U TIME, the video series is not complete. You can check out part 5 comments, 7 month ago this guy promised a new video in 2 weeks and never delivered. The video series stops at authorization, it doesn't get to the banking API. The code he wrote during these 5 tutorials has a lot of temporary solutions, which he promises to fix in future videos that don't exist. It's ridiculous it's called a COMPLETE JSON API, I have no idea why there is so much positive feedback here, it's a scam
