Local Store

TSCord uses rxeta to store reactive data at runtime. This library was written especially for this project.

It uses rxjs and a dead simple get/set/update interface to manipulate data in a reactive and efficient way.

Initialization

First, you need to define the shape (interface/type) of the data you'll store in the Store service:

src/services/Store.ts

interface State {
    count: number
}

Then, define the initial state of your data when the bot starts:

src/services/Store.ts

interface State {
    count: number
}

const initialState: State = {
    count: 0
}

Usage

Now, you can use the Store service to get/set/update your data:

src/services/Store.ts

import { container } from 'tsyringe'
import { Store } from '@/services'

const store = container.resolve(Store)

//set
this.store.set('count', 1)

//update
this.store.update('count', (count) => count + 1)

//get
const count = this.store.get('count')
console.log(count) // -> 2

Subscriptions

The whole point of this store is that it is reactive. So you can subscribe to changes in the data (weither the full store or a particular state) and react to them.

src/services/Store.ts

import { container } from 'tsyringe'
import { Store } from '@/services'

const store = container.resolve(Store)

store.subscribe((state) => {
    console.log('The whole state has changed!')
    console.log('New state:', state)
})

store.select('count').subscribe((count) => {
    console.log('New count:', count)
})
