What is lowdb?

Lowdb is a small local JSON database for Node, Electron, and the browser. It's a simple and lightweight way to store data locally using a JSON file. It is ideal for small projects, quick prototypes, and applications that do not require a full-fledged database.

What are lowdb's main functionalities?

Create and Read Data

This feature allows you to create and read data from a JSON file. The code initializes a lowdb instance, sets default values, adds a new post, and retrieves it.

const low = require('lowdb');
const FileSync = require('lowdb/adapters/FileSync');

const adapter = new FileSync('db.json');
const db = low(adapter);

db.defaults({ posts: [] }).write();

db.get('posts').push({ id: 1, title: 'lowdb is awesome' }).write();

const post = db.get('posts').find({ id: 1 }).value();
console.log(post);

Update Data

This feature allows you to update existing data in the JSON file. The code updates the title of the post with id 1 and retrieves the updated post.

db.get('posts').find({ id: 1 }).assign({ title: 'lowdb is super awesome' }).write();
const updatedPost = db.get('posts').find({ id: 1 }).value();
console.log(updatedPost);

Delete Data

This feature allows you to delete data from the JSON file. The code removes the post with id 1 and retrieves the remaining posts.

db.get('posts').remove({ id: 1 }).write();
const posts = db.get('posts').value();
console.log(posts);
