SignalDB

SignalDB is a client-side database optimized for modern web applications. It provides an optimistic UI for creating responsive and dynamic interfaces, a MongoDB-like interface for familiarity, and robust TypeScript support to ensure type safety and accelerate development. SignalDB enables versatile local data persistence with support for various storage providers and facilitates real-time updates by gathering and synchronizing data from multiple sources. Its framework-agnostic design makes it suitable for projects of any scale, offering instant data access with minimal latency, which is ideal for applications requiring fast data handling and real-time interactions. Adapters are available for popular reactive libraries, including Angular, React, Solid, Svelte and Vue.js.

Installation

  $ npm install @signaldb/core

Usage

import { Collection } from '@signaldb/core'

const Posts = new Collection()
const postId = Posts.insert({ title: 'Foo', text: 'Lorem ipsum …' })

Posts.updateOne({ id: postId }, { // updates the post
  $set: {
    title: 'New title',
  }
})

Posts.removeOne({ id: postId }) // removes the post

const cursor = collection.find({})

// returns an array with all documents in the collection
// reruns automatically in a reactive context
console.log(cursor.fetch())
