Etat

Etat means "state" in french

Experimental global store for Solid focused on size and extensibility. This is essentially a global and safe way to have Solid's stores via Context API. If you want a more thorough solution, check out solid-pebble.

Installation

$ npm install @amoutonbrady/etat
$ pnpm install @amoutonbrady/etat
$ yarn install @amoutonbrady/etat

Getting started

1. Add the global EtatProvider

   // index.tsx
   
   import { render } from 'solid-js/web'
   import { EtatProvider } from '@amoutonbrady/etat';
   
   import { App } from './app';
   
   render(
     () => (
       <EtatProvider>
         <App />
       </EtatProvider>
     ), 
     document.getElementById('root'),
   );

2. Define your stores globally

   // store.tsx
   
   import { createEtat } from '@amoutonbrady/etat`;
   
   export const useAuth = createEtat('auth', {
     token: '',
     get isAuthenticated() {
       return this.token.length > 0;
     },
   });

3. Use them as you please accross the whole app

   // login.tsx
   
   import { useAuth } from './store.tsx';
   
   export function Login() {
     const [_, setAuth] = useAuth();
   
     function login() {
       return setAuth('token', 'abcde');
     }
   
     return <button type="button" onClick={login}>Login!</button>
   }
   
   // app.tsx
   
   import { Show } from 'solid-js';
   import { Login } from './login.tsx';
   import { useAuth } from './store.tsx';
   
   export function App() {
     const [auth] = useAuth();
   
     return (
       <Show
         when={!auth.isAuthenticated}
         fallback={<p>Your are logged in with the token {auth.token}</p>}
       >
         <Login />
       </Show>
     );
   }
   

API

• createEtat<T>(id: string, initialValue: T): () => [Store<T>, StoreSetterFunction<T>]
  • id : This is a unique name that's being used to store the store value.
  • initialValue : This is the initial value of the store. It should ba an object. This will become a parameter of a createStore function.
• EtatProvider : this is the global provider. Without this, the stores won't work. I didn't add any check for this.
