You may be using fetch with async/await wrong...

I only catch errors so I can throw them myself.

[KirkWaiblinger]

The cause field is intended to be used for rethrowing exceptions. It is the corrolary to an innerException in other languages. This is not a standard usage of the cause field.

The perfection is hard in this industry

This JavaScript videos that YouTube suggest always remind me of how helpful are static types and type-safety when developing reliable software.

[fueledbycoffee]

i even go further and i pass all my requests thro request handling async functions to abstract out the error handling to a single function so i can just worry about fetching/posting/puting data

[rafaelmramblas]

Or you can use Axios and its interceptors, which you can do it globally on your app. Using interceptors, you can focus on creating async services as atomically as possible.

[darekcybulski]

Yeah, though for the sake of type safety you might want to create your custom error class, as the native one accepts only one parameter and it's a string message.

[Dev-Siri]

this is the best solution actually. I used to use Axios, but now I prefer creating my own fetch wrappers. more control + smaller footprint = smaller bundle size

Started playing with wretch recently. Nice addi tion over fetch

[FalconTheFries]

This is why I call database directly from frontend, which itself is a Sqlite that's deployed along with HTML and Javascript

You also forgot to parse/validate the user object into a known object structure!

[AndrewFloatrx]

also we can use validators like `yup`... also we can use global handler for all rejections `addEventListener("unhandledrejection", (event) => {});`

[josemarin]

use monads and functional async without even know these concepts. love "plan" in js-awe library.

[ofeenee]

And if the response was text and not json?

[nowayicommented]

You still need to check if user is an object and if the properties exist before accessing them

[Kim-trop]

that looks like acid to write and read

[fromant]

Handling errors is a very important thing. My parents handled me for 20 years and I'm getting better

[reinhard_silaen]

Great video. How did you make the subtitle like that?

[shivamjhaa]

Great video. Btw I mostly used axios for real user apps mainly due to middlewares

How can you do middleware request like axios using fetch (autonatically adding auth headers and trying max 3 times if request fails) ?

Can you doa video on same?

[anuradhaamarasinghe]

can't you just check res.status directly ?? Sorry the noob question
