🗂️ Stoxy

Stoxy is a state management API equipped with Web Components.

Stoxy allows you to easily handle, persist and update data in your DOM without the weight of a framework.

❓ How

Stoxy utilizes the browser's tooling with respect to your computer's memory.

Stoxy stores the data in a in-browser Database called IndexedDB, only keeping the latest 5 accessed objects in-memory for faster access.

Stoxy utilizes a promise-based use flow making it really easy to asynchronously read and write from the storage.

If your browser doesn't support IndexedDB, there's no need to worry. Stoxy recognizes these cases automatically, and opts out of using it and utilizes a in-memory system only.

❓ Why

Motivation

The motivation behind Stoxy as to provide a simpler solution for cross-app state management.

With Stoxy you are up and running after writing just one line of code. After setting your first state object, you have a functional state system ready to be used.

import { write } from "@stoxy/core";

write("users", userList);

Simplicity

All of Stoxy's commands are 1-2 parameters long, and can be executed as "one-liners".

They are however extremely extendable due to the nature of the state management system of Stoxy. Some of the Stoxy core functions like update and remove even take delegates or predicates as a parameter to give the developer more control over their state management.

Ecosystem

Stoxy ships with a small set of Web Components, which are framework agnostic components ready for use in any project.

The components are built to as reactive pieces of an application, updating their contents according to state change without the developer having to do any work.

When writing websites with dynamic content, the markdown can easily become a spaghetti of plain text and Javascript escaped variables inside a template literal. like:

<h1>Hello, ${user.name}</h1>
<p>Your profile has accumulated ${user.viewCount} views</p>
<p>Top 3 visitors on your page:</p>
<ul>
    ${
        user.topVisitors.map(vis => `<li>${vis}</li>`);
    }
</ul>

With Stoxy, the same markdown could be created without being in the same context as the data with:

<stoxy-object key="user" prefix="u.">
    <h1>Hello, u.name</h1>
    <p>Your profile has accumulated u.viewCount views</p>
    <p>Top 3 visitors on your page:</p>
    <ul>
        <stoxy-repeat key="user.topVisitors" id="vis">
            <li>vis</li>
        </stoxy-repeat>
    </ul>
</stoxy-object>

⚠️ Dynamic content inside Stoxy Elements updates when the data does. Update once, DOM updates everywhere.

Persistence

Stoxy comes shipped with persistence out of the box. There are many cases in which it is beneficial to persist the state data through page reloads and navigation. Wether it be stale-while-revalidate patterns, or just static information fetched from the API.

The Persistence in Stoxy is opt-in, meaning that you control exactly what information gets persisted.

Use them how you want to

The whole core set of Stoxy is built from smaller modules, which can be attached at will.

This means that you can use Stoxy only for managing state, and then handle all the events through subscribers, or you can go all in on Stoxy and deploy a whole application built with stoxy elements using barely any Javascript

🔔 Reactivity

Stoxy is a reactive state management system, meaning that when you update the data in Stoxy with the write command, all of the elements using that object will automatically update their content in the DOM.

No more need for flowing data around the whole system.

write('user', newData);

// Triggers update in the element below

<stoxy-object key="user" prefix="u.">
    <p>Hello, u.name</p>
</stoxy-object>;

Stoxy will not update any element which's data didn't change, enhancing the performance greatly.

_ Only the DOM elements which had their data changed will be updated _

🧰 Installation

To install the full stoxy suite, run

npm install @stoxy/stoxy

You can also install packages from the stoxy suite as standalone modules.

npm install @stoxy/core @stoxy/string @stoxy/repeat @stoxy/form @stoxy/object

Usage

Stoxy can be used currently in 3 ways, which interoperate between each other:

1. With just the @stoxy/core and the function below
2. With Stoxy Elements
3. With Stoxy Element Mixin

You can freely mix and match these implementations too!

Write

import { write } from '@stoxy/core';

write("counter", 0);

---

import { write } from '@stoxy/core';


write("Shoppingcart", [{id: 123, name: "Free gift"}]);

Read

import { read } from '@stoxy/core';

read('shoppingcart').then(shoppingCartItems => {
    shoppingCartItems.map(item => console.log(item));
});

---

import { read } from '@stoxy/core';

async function getItems() {
    const items = await read('shoppingcart');
    return items;
}

Sub

import { sub } from '@stoxy/core';

sub("shoppingcart", updateItemCount);

function updateItemCount(e) {
    write("itemcount", e.data.length);
}

Clear

import { clear } from '@stoxy/core';

clear('shoppingcart');

Update

import { write, update } from '@stoxy/core';

write("counter", 0);

// Update counter every second
setInterval(() => {
    update("counter", counter => counter += 1);
}, 1000);

Remove

import { remove } from '@stoxy/core';

// Removes product with the id 1
remove("shoppingcart", product => product.id === 1);

---

import { remove } from '@stoxy/core';

// Remove all products with a price over 5
remove("shoppingcart", product => product.price > 5);

---

import { remove } from '@stoxy/core';

// Remove all meat
remove("shoppingcart", removeMeat);

function removeMeat(product) {
    if (product.type === "Meat" || product.type === "Chicken") {
        return true;
    }
    return false;
}

Persist key

import { persistKey } from '@stoxy/core';

persistKey('shoppingcart');

// with multiple keys
persistKey('shoppingcart', 'history', 'address');
