formik VS MobX

I use Formik in an app of mine, but I wouldn't pick formik for a new React project.

If you've looked into form validation with React, you'll likely have heard of Formik. My first run-in with Formik was at a large company I worked; it was already established as the go-to form library for our projects, and I immediately fell in love with it.

First things first, we'll need to update Supabase to the latest version (v2), and install Formik (+ related dependencies) and the Next.js Auth Helpers:

Also, FastField doesn't work if you're using the useField hook to create composable fields. The useField hook was set to become more performant in Formik v3, but I'm not sure if v3 will release, and it's open-source software, so no one owes that update to us Formik library consumers.

Here's 8 days ago, there's dozens of these if you do a search

I wonder if any of you used react-hook-form or formik and if you did, what where the struggles that you had? I'm interested in particular scenarios that you encountered. Components that did not really click. Stories where you had to throw everything out and start from scratch, that sort of thing.

Firstly thank you for all your help on other issues through countless forum/github comments! Secondly, this worked a treat - turns out it was an issue with Formik (PR) using a legacy version of deepmerge .

States can also be organized in some central places (aka. stores). You can use Tini Store (very simple, ~50 lines) or other state management solutions such as MobX, TinyX, ...

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

MobX

Mutable-based: leverages proxy to create mutable data sources which can be directly written to or reactively read from. Candidates in this group are MobX and Valtio.

Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/

Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity".

Observables otoh say "fuck it, I'm mutating everything, do what you want with it".

MobX Documentation

There's also others libraries like https://github.com/mobxjs/mobx which aren't specific to RN but can be used in any JS environment.

Valtio is like simplified MobX
