Examples

Data fetching and React

Next.js + Reatom

A close-to-real-life example of SSR (Server-Side Rendering) with API data hydration. The cool thing is that the code is almost isomorphic. You can check this commit to understand how simple it is to turn on SSR for an existing code with Reatom.

Migration from RTK

Search component

This example is close to real life and shows the complexity of interactive UI. It uses async package to handle classic search edge cases and made perfect UX.

Dynamic atom creation

This example shoes how to use atomization to improve editable fields performance, persists it to localStorage.

Data fetching and Svelte

Tree-like dependent reactive structure

Nested checkboxes with indeterminate states could be realy hard and unoptimal in reactive context. This example shows the complex optimized model for tree-like structure, check the model file

Managing notifications

This example perfectly illustrates the benefits of atomization and reusability within the Reatom ecosystem - reatom/timer.

  • Domain-Oriented Code: You don’t need to normalize data, store states in separate lists, select and modify them by IDs. Instead, you can describe the entire logic in one factory, making it safer to create instances of your models. This significantly reduces and simplifies the code. While you can use classes, I prefer factories.
  • Isolated States: Since states are highly isolated into atoms, they are also easy to use in the view layer. Take a look at App.tsx for an example.
  • Versatile Use: reatom/timer is not limited to Pomodoro demos, it can be used to manage the progress of just about anything. It comes with settings for update frequency and pause control out of the box.
  • A Nice Bonus: The essence of atomization lies in state isolation, which is more performance-optimized compared to managing elements by recreating lists in Redux and Effector.
