Separation of rendering vs logics custom hooks Jun 24, 2022

Show notes

I recently joined a company where they use a lot of custom hooks for separating logics at the level of a component.

When to break up a component into multiple components

Imposter Syndrome and Working at FAANG Jun 24, 2022

Show notes

Hello Kent, my name is Joshua Osagie, I'm a software developer focusing mostly on front-end dev (https://www.joshx.dev my portfolio website).

I made this call because you've been a big inspiration and model in my React/JavaScript journey. I've taken some of your courses on egghead.io and recently I told my boss about your EpicReact course.

I really appreciate what you're doing in the React/JS ecosystem, and I do hope you receive this recording.

Thank you!

In a Startup only testing in the backend? May 19, 2022

Show notes

Startup says that we should be only testing on the backend, since the frontend is changing so fast, so no need to test the frontend, just a couple of integration tests.

Using GraphQL queries in Remix loader functions May 17, 2022

Show notes

Hey Kent! We've been using Hasura to generate CRUD APIs for our small team. Our existing web applications are all using Next.js, and consume the GraphQL API via Apollo Client and TypeScript hooks generated from the remote schema using graphql-code-generator. This workflow has saved us a lot of time, particularly in API development, and I love the generated type-safe hooks. After watching your new Remix content, we're very excited to try Remix as an alternative to Next, mostly to leverage the performance benefits and the effortless error boundaries within nested routes. Do you have some best practices for utilizing GraphQL queries in Remix loader functions? It would be great for us to continue to take advantage of code generation, if possible. Thank you so much!

Servers + Databases + Remix May 17, 2022

Show notes

I am trying to figure out my stack on the backend side of things for Remix, more specifically services that will allow my server side code to run at the edge be it the server itself or the database or both so that everyone everywhere can use my app at super fast speeds. There are not a lot of resources out there about the best services out there that do this and I am wondering if you have any suggestions where I can begin to look for such services

How can I incentivize users to not share accounts? May 17, 2022

Show notes

I would really prefer to use magic links for authentication rather than username/password. However, I'm running into an issue where several of our clients share a single account login which means many people logging in don't have access to the email inbox. We already don't charge per user, but have you come across this situation before? Any tips on how we can incentivize users to use individual accounts?

Could the useState be used without the setter? Dec 13, 2021

Show notes

I have a question... could the useState be used without using the setter? because a teammate use it in that way to get an item from sessionStorage

const [initialScrollPosition] = useState(() => Number.parseFloat(sessionStorage.getItem('offset') || 0));

and argues that this is so that the component is not unnecessarily rerendered and to read the sessionStorage only once! 🤔 but I think we can use useMemo for those cases but the useState is still used in this form in several components.

useState lazy initialization and function updates

Best way to reset a form Dec 07, 2021

Show notes

This is a question about: Improve the Performance of your React Forms

In the example, submitting the form successfully will still retain the current values of the fields.

I want the behavior such that"

when the server response says the form is NOT submitted successfully, then the form field will have the current values that has been inputted by the user
But when the server response says that the form is successfully submitted, then the form fields will be blank again.

What's do you think is the best and most performant (and readable) code to approach this in pure React? The approach which will reduce the amount of unnecessary rerenders of the fields?

Thank you!

How to decide among advanced react patterns? Dec 02, 2021

Show notes

So this short call is about when to use which advanced react pattern to create re-usable components. Like are there any indications or things that make you think about why one approach is better than the other.
