Introduction

Stayte is a library that helps you to create persistent state in your application by using every possible peristent storage (cookies, query, local storage or session storage) in natural way.

tired to re-invent the wheel at every new project, Stayte is here to help you to save time and effort.

It's inspired by the concept of signal and it's a great fit for React applications, but it can be used in any JavaScript application.

Stayte could also be used in the server side by applying a simple patch (only next.js is supported for now).

Features

• 🔌 Signal-like
• 💾 Persistent state
• 🔍 Type-Safe
• 📡 SSR Friendly
• 🧪 Fully tested
• 📦 Zod validation

Inspiration

The name stayte is the concatenation of the words "stay" and "state".

Stayte is inspired by multiple libraries, here is a list of them:

• Nuqs
• Preact signal
• Jotai

Concept

What is a "persistent state" ?

A persistent state is a state that is stored in a place that is not destroyed when the application is closed, like a page reload or a tab close.

There is many different area that is used to store a peristent state

• Local storage (client)
• Session storage (client)
• Cookies (SSR)
• Query string (SSR)

In many project, as a developer, you will need to interact with a peristent state by using the native browser API or by using a library

Problem, there is no library that regroup all peristent state in one place, with a unified API.

Stayte is here to help you to save time and effort.

What is a "gluon" ?

A gluon is the smallest unit of stayte, it's a class used to interact with every peristent state.

He's able to subscribe to changes, set a value and get the value.

It's look like a signal from preact

Also a gluon can be composed of other gluons and make a chain of reaction.

:::info The name "gluon" is inspired by the physical gluon, it's a quantum particle that is responsible of the link between the quarks. :::

Basic usage

Declare a gluon

The first way to use staye is to use it in vanilla javascript code.

You declare a gluon by calling the gluon funcition and passing the name of the gluon and the source where the gluon will be persisted or not (memory source)

import { gluon } from "stayte";

const nameGluon = gluon('name', {
  from: <source>
})

allowed source are:

• query: The query string of the url
• cookies: The cookies of the browser
• localStorage: The local storage of the browser
• sessionStorage: The session storage of the browser
• memory: The memory of the browser
