Kent Dodds - Advanced hooks

Kent Dodds is a pretty famous (at least in React land) trainer, conference presenter and blogger. Has courses on egghead.io and more

Has a his own training workshop series on react: https://kentcdodds.com/workshops/

I saw he had an online training coming up and really wanted to participate and learn from him. I've worked with hooks such as useEffect and useCallback so I decided to step up to the Advanced Hooks course, more: https://kentcdodds.com/workshops/advanced-react-hooks


I'm leaning advanced hooks myself so my intent is not to teach you how to use these hooks. My intent is to share my experience and the materials to inspire and guide you to learn more yourself.

Do prepare in advance of the course: 

- setup zoom

- his KCD workshop prep

- pre-requisite material

- the coursework itself


Kent moves quickly in his online courses

His intent is not that you learn everything and get all exercises working in the training session. So you have to revisit later

Kent also drops a lot of extra cirricular material, blog posts, libraries etc. so you learn more than just the coursework. Checkout the following list:

This is a really cool video that both goes into a bit of how hooks work, and then how useful composition via hooks can be (the second half, with Michael Jackson).

  Q. would you have 1 single context for the app or multiples?

  A. Kent prefers to avoid single global context, he prefers to separate by domain

  such as modal context, other context etc. read more on:

react-router v6.4+ loaders, actions, forms and more

react-router  react-router is used for in app single page app navigation, we configure routes for pages in the app to map to components react-router has over 1bn downloads, its an industry standard (but there are others e.g. Nextjs router) many apps use react-router, many on v5.x the new react-router 6.4.x the newest major version of react router v6.4 is a significant enhancement which adds a lot of new features. react-router v6.4 offers new features to load data (loaders) and handle actions (actions).  It's done gone all Remix-y which makes sense because the same guys wrote both. eliminates a lot of boilerplate code to fetch data in useEffect() and set various loading states put your data load and update logic in react-route components instead of custom code unlike Remix, react-router v6.4 is still just all on the client (not server like Remix) paradigm shifts Lets start with a couple of high level ideas; "back to the future" so to speak OR "what's old is new ag
