# CRDT Continuous Sequence

## Install

```

npm i -s crdt-continuous-sequence

```

## Usage with plain array

```js

import { ContinuousSequence } from 'crdt-continuous-sequence'

const cs = new ContinuousSequence();

const todos = [

    {

        id: 1

        name: "Groceries"

    },

    {

        id: 2,

        name: "Cleaning"

    },

    {

        id: 3,

        name: "Admin"

    }

]

// move 'Admin' between 'Groceries' and 'Cleaning'

cs.move(todos[2], todos[0], todos[1]);

cs.sort(todos);

console.log(todos);

```

## Usage with GUN

```js

import Gun from 'gun/gun'

import { GunContinuousSequence } from 'crdt-continuous-sequence'

const gun = Gun();

cs = new GunContinuousSequence(gun);

// Initialize sequence

gun.get('todos')

    .set({ name: "Groceries" })

    .set({ name: "Cleaning"})

    .set({ name: "Admin" })

// Load items

const todos = [];

gun.get('todos').map().on(todo => {

    let index

    if ((index = todos.findIndex(todo['_']['#'])) > -1) {

        todos[index] = {...todos[index], todo}

    } else {

        todos.push(todo)

    }

    cs.sort(todos);

})

// Later

// move 'Admin' between 'Groceries' and 'Cleaning'

cs.move(todos[3], todos[0], todos[1])

```
