Do you like programming in Go? If you do then this video is great for you! In this tutorial video I share with you how to make an API in Go! More specifically we are going to be using Gin which is a high performance and relatively simple web framework that will allow us to quickly design and make an API in Go. Hope you enjoy!

I love the fact that you leave your mistakes in. It shows us that even super human programmers make mistakes, gives me a chance to pause and take a stab at the issue, and finally you break down your thought process behind the troubleshooting.

Great tutorial, Tim (as always!). It's good to see some tutorials that are not just going over basic syntax. This is still very simple but it illustrate a real world example!

Can someone tell what Go extension for vscode is used in this tutorial? I am using just "Go" extension, but I really hate the way it formats the code on save action and also it replaces spaces for tabes. And the problem is that I can't find the point in extension settings where I can fix these behaviours...

@josephtucker9612 3 дня назад

I had an error that said main() did not exist in the package when it did. The problem was I had to save the file. I had saved it earlier after entering my imports but the imports disappeared due to it not being used. StackOverflow was not helpful on stupid mistakes.

Hello, which Go extension do you use? My json tags are not showing up.

@TheChemicalWorkshop 2 года назад

@pranavsharma7479 11 месяцев назад

There is no need to use json tags in the book struct as the IndentedJSON fucntion encodes the go structs into json itself.

@nitin_puranik 6 месяцев назад

Loved this tutorial, very helpful! Thanks, Tim. The only thing I didn't quite follow was why you used router.PATCH at 33:05 - didn't quite get the rationale behind when to use PATCH versus POST.

@madhavan_vj 6 месяцев назад

Post is not idempotent i.e will create duplicate resources instead of updating the existing one.

@jonathanlambrecht5642 9 месяцев назад

im just starting, few weeks watching some videos, mainly for deciding my route learning go (not falling for tut hell again as i did learning arduino/pic and it took a lot of time), and what i get from this video is that this is very simple, but i do not undestand what and why the framework is doing whatever it is doing (because i do no get it lol) so i think i need to learn without any framework, the same goes with gorm, yeah pretty straight forward, but i think im going to study postgres too, maybe im wrong or dumb for not getting how this works, idk...any thoughts?

@huntercoleman1347 6 месяцев назад

If anyone is having issues with the PATCH command not working, your curl may be aliased to Invoke-Webrequest. In the terminal, run Remove-item alias:curl and then run the patch command again to checkout a book. I was getting frustrated trying to figure this out, so hope this helps if anyone else is having the same issue.

@ezrablack5395 7 месяцев назад

Great video Tim! For anyone else running on MAC, if you get the error zsh: no matches found: localhost:8080/checkout?id=3 then run the curl command like this - curl -s -X PATCH 'localhost:8080/checkout?id=3'

@beaumontyun3872 2 года назад

Surprisingly I could not use curl to do a PATCH request, whereas it's possible for any other request. It was only available when I used Postman or Insomnia to do the PATCH request, so strange...

@gustocoder8900 7 дней назад

Unlike with with GET and POST requests, the '?' chartacter in the URL is being interpreted by the shell as a special character eg a wildcard, hence the request will not work as expected. To prevent this; you need to either escape the ? character or put the URL in quotes. So, do it like this: curl "localhost:8080/checkout?id=2" --request "PATCH" OR curl localhost:8080/checkout\?id=2 --request "PATCH"

Can anybody tell is gin framework a third party package or not ?

@ScottKFraley 2 года назад

Really curious about why you made the struct'd Id field a string vs. an int or other 'actual' numeric value? :)

@rssaiganesh Год назад

Late reply, not sure if you already have found the answer, but i believe it's because the id is being used in the GET method of bookById. Can anyone let me know if i am correct in this?

@YnjeviYhhei Год назад

in a real DB it would be an uuid which is a string

@Chips4Real1 Год назад

why would u need it to be a number, youre not gonna be adding or subtracting ids from each other

@ScottKFraley Год назад

@@YnjeviYhhei Not necessarily, but I get your point.

@ScottKFraley Год назад

@@Chips4Real1 Takes way less space that way, no? I've NEVER used a string as an ID unless it was in fact a GUID/UUID. I mean, I definitely would NOT store a phone number as an actual number because no reason. But I have had plenty of tables that used either an int, or a bigint (long in C#) and again, it's my understanding that numbers take way less space than a string does. (Depending on the length of course. But a short string won't be a good Id for a table unless it's a really small / lookup table or some such.)

@siyaram4237 Год назад

Great tutorial but, I was expecting you to test the API endpoints on applications like Postman. Apart from that I was hoping you would saperate things in folders like, Struct folders, Controller folders and Repository folders.

Has everything to be on a single file? Every tutorial I see everything is always on the same file. I want to structure my code, over multple files so, that go doesnt look like spaghetti code.

@jotunros 5 месяцев назад

Unfortunately most of his tutorials are like that. I treat it as nothing more than prototyping just so you can quickly "dip your toes in the water" so to speak. You need to actually look for some other resources on design. Most commercial applications will have tons of more work to be done when implementing a single rest service/microservice. I come from Java so a good point of reference is how the Spring Boot Api services are structured.

@esper4605 2 года назад

That's a question that I've mulled over for a long time! I feel like the more we become dependent on high level abstract tools, the less we need to know of the actual "rules" of writing software that performs specific tasks. At the end of the day, we're telling someone's tools that they wrote to tell someone's tools that they wrote to tell someone's tools (etc etc). I feel like we're hitting a point of fragility. It's VERY important to understand how to use lower level languages in case everything needs to be torn apart and redone from scratch. It's ALWAYS important. This is the "zombie apocalypse" of software development, but it is a true fear I have had for a long while.

@jessicadowning3170 Год назад

It was really helpful for me to see him make mistakes and then go back and explain why he made a mistake. I learned a lot from his video and I'm sure he did too. One of the best ways to solidify something you've learned is to teach it to someone else. If no one ever taught things they hadn't already mastered, there would be a lot less knowledge shared. Don't discourage people from sharing just because you're grumpy.
