How To Build A Complete JSON API In Golang (JWT, Postgres, and Docker) Part 1
Вставка
- Опубліковано 3 лис 2022
- 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.

Thanks for watching
In case someone is still confused about why the Content-Type wasn't applied properly, it's because WriteHeader(200) starts writing to the connection and sends all headers set up to that point. Headers set after calling it are simply ignored.
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
Hallo Anthony, bedankt voor deze training, dankzij jou heb ik Golang ontdekt en ik heb er echt van genoten.
Je doet het heel goed en je bent een goede leraar, ook Belg, dat is een plezier! Tot ziens in de laatste aflevering!
this tutorial was unbealiaveble. The amount of things you managed to fit in one 30 min videos! thank you
💪
This video is a clear example of "from 0 to hero in 30 mins"
Kissass
Not from 0, you already have to know the basics of GO to understand it
Thanks for the video, much appreciated.
Learning go, so seeing someone work from scratch is more useful than you would believe!
Great content. Thanks!
Anthony you are awesome in teaching golang on youtube
we need more contect about golang especially projects like that
Thanks again for your big and helpful effort
These videos are incredible. Thank you. :)
This is the best go API tutorial I've ever watched. Thank you so much for your awesome content and for teaching us the best practices 🔥
Great video!
Best channel for golang especially backend thank you sir
amazing 🚀
Jij bent echt een baas man! Ik kan uren naar je nuchtere video's kijken man. Petje af!
Ha! Thanks !
Love the style and the approach to teaching. Excellent stuff, please keep it up
Thanks man. Hands-on content 🤘
Amazing video, so informative, I like your rhythm and enthusiasm, congrats from Brazil xD
thank you for this super valuable appreciate the hard work here
this is just epic, love the Bob Ross references
Thankyou for a Gin free API development tutorial
Man! you are the Top G of Golang
echt een held je bent toch uit België ik hoor het aan sommige woorden ben goed met veel talen maar probeer nu go lang te leren en deze tutorial heeft hard geholpen
Hey King, you dropped this 👑
Your content is so powerful! Very helpful in terms of quality and speed. I'm learning so much at such high speed. Plus the teaching style is engaging, you make the students think which is way better than a scripted tutorial. Thank you so much 😊
Thank you ❤️
Awesome!
And yeah, you're freaking fast! :D
im glad i found your channel!
🤝
thank you for this tutorial! is excelent and help me :D
Your teaching style is second to none!
Thanks my man!
for 24:29, You can just select the option of JSON in postman, It will show the data in JSON format.
please collect all your projects into respective playlist, it's really difficult figure out which video belongs to which project
all streamed video projects, recorded projects with proper naming convention(part-1,2,3 etc) and if all could be accessible from playlist button then that will be really helpful.
hope you will get some time to do this housekeeping activity Anthony.
thanks for all the efforts Anthony, you have created energy and interest in me to learn golang.
Will do this over the weekend. Thanks for the feedback
Would be amazing if Unit Tests would be also covered
great stuf!
Really valubale and High quality content . Just one thing please : can you make the code font just a bit bigger to be easier to see ?
You are from gold man!💪
Thank you.
Request, make video like this again please.,, it beautiful
Would be nice to hear your recommendations now that mux is no more
Hey , didn't know Johnny Sins was also a developer
Jokes aside, awesome tutorial man, I'm getting started with go an seeing you gliding through helped me a lot with the understanding of the language
Johnny is a versatile actor
Moving too fast, can't keep up with all the great content Anthony is creating.🚀🔥
Lightning speed
High value content at the speed of light
Speed is good. You can always pause :)
Thanks for your content!
One question I have, is there a reason in the handlers to return a reference (&Account{}) instead of just Account{}?
Maybe we need to update state. Maybe
Thanks for this amazing tutorial! Quick question:
For mux routers, they have a function called Method that lets you decorate the handler with accepted HTTP methods. Could we use that instead of having a generic handle function for handling the method types?
so Go is better for rest api or Rust? thank you
Hello,. Thank you for your content it's very interesting. I see that all your project you start with Makefile. On some of your videos I saw the MS Windows start button. Which make do you use?
To solve the JSON content format you have to set headers before writing
```go
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(status)
```
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.
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!
Please make a tutorial with rust+axum for same project.
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?
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 :)
please also include nosql database too..thank you for starting this.
We will set the project up so that adding new types of storage can be implemented easily!
I thought Johny Sins has started teaching programming 😂 Although, very useful tutorial, thanx a lot!
Thanks for this great guide ! If you had to redo this with a differernt router than Mux, that is no longer maintained, which would you have chosen and why ?
Echo. Because I use this.
What part of the video covers docker?
Hello Anthony, thanks for the tutorial! BTW are you Turkish? My assumption in based on your soft pronunciation of `R`s in word endings, am I right?
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?
Lowercase methods are private. Uppercase are public. I know, super awkward
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.
Really good content! I'd like to know what is your code editor theme. ✌
Gruvbox
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 ?
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.
OMG!
Amazing video but you should ditch make for go-task... It's a task runner built in go.
are you using a vim plug in for vs code? Which plug in?
The default official one
Awesome tutorial. How can i implement authentication in this api. a sign in and sign out route.
Any tips how to get postman to send request? At 23:30
an time i watch your videos i stop the video maybe 232343 😅😅 time to understand what are u do ,thank you
hey the reason your content type was not "application/json" is because you called writeheader before header.set When you call WriteHeader(statuscode) you set the status code and send the status line and all the headers to the client thus not being able to set headers after it
What logger do you use?
Think its logrus "github.com/sirupsen/logrus"
Thanks! Great video btw..
Thumbnail 😂 👌
Very good video but the library used here is no longer mantained, be carefull!!.
True!
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
Why mux and not gin for example?
Both are fine.
15:25
pretty please, needs to be zoomed in for the mobile users
Zoom your phone or pay me money
make run not work for me
The guy doesnt give the fish but teaches how to catch it
Did you find what's was wrong with content-type?
I think it was header.Add that was the cullprit
@@anthonygg_ If you write bytes to the response, then you cannot write a header after the fact. So first setting headers then WriteHeader for status. It will work! 😌
@@fannigurt Dayum this is so true! Thanks for this!
With the mux router you can specify the method for the route 15:41
router.HandleFunc("/accounts", makeHTTPHanlerFunc(s.handleGetAccount)).Methods("GET")
Thanks!
where are you from?
Belgium
I am still stuck at understanding your error handling methods. I think they need their own session

in 30 min? ok let me see this
I think this is part 1 😢
I'm afraid of using golang web framework. My fear is that in some day they will just stop being maitained and booom! need to migrate
Yo, t'es francophone ?
Please zoom in when you're coding! I can barely see the code!

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
The bastard! Lets call the police.
@@anthonygg_ Yeah, yeah, very funny. Waste your viewers time and then mock them in the comments
Look is American but the sound is indian
Hi @anthonygg_ could i ask you, what is your vscode theme?
GruvBox
oh great, and now mux is deprecated
gorilla mux is dead any good alternative recomendation.
Fiber , echo or maybe gin all three are solid
