It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.
Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.

SWR for react, and to use useReducer.
Ppl, you need to know the main reason to use useReducer: it has NO dependencies!!!
Can you imagine to use your state changing functions without to worry with dependencies? It's awesome.
Not entirely dev-related, but I found out that AP exams are essentially useless in later life.
Now please excuse me while I go study for the APUSH, AP Calc, and AP English exams my school has forced upon me.
I also learned that using
create-react-appsets up a PWA manifest for you, and makes offline service workers easy to add as a feature...I learned how elegant component libraries and frameworks can be when you're not entirely fluent in CSS. I love frontend but hate writing CSS, so using a component library like ChakraUI or even using something like Tailwind makes the process of creating websites so friendly. 🤷♂️
How In-App-Purchases work and how to build them into a mobile application. It's been kind of a headache these past few weeks, but it always feels great to make it to the other side with 2 more gray hairs and a happy disposition.
Learned how to better parse markdown server-side using remark and rehype.
Learned a bit more about META tags. Didn't know there was a meta tag property for crawlers not to follow the website.
Also learning more about Remix (the React meta-framework) everyday.
That's awesome! 🔥
Ðat JavaScript REALLY needs a way to load local files client-side.
I'm assuming you mean JavaScript in a web browser and not Node.js.
You can read local files using browser file APIs if a file is added via an <input type="file" /> on a page.
That's pretty much what you're restricted to for security reasons.
Yes.
I do mean in ðe browser.
I don't want to use
<input>because ðen ðe user's gonna be like "What the hell do they mean find the "main file"??" and be why ðe app doesn't start working right away.I just don't understand how ðere could be security issues reading local files, especially if ðey were bundled wiþ ðe HTML.
This week I learned about account management and security concepts in Snowflake to help prepare for certification.
I learned about networking, DNS service discovery and Traefic. Seemingly just scratched the surface, but it's a technology I'm curious to learn more about.
Nice!
Awesome!
Docker compose and Mysql.
Let's go!
