Easy to learn

Dexie was written to be straightforward and easy to learn. If you've ever had to work with native IndexedDB then you'll certainly appreciate Dexie's concise API.

Easy to sync

With only a few lines of extra code, you can build a consistent, authenticated and access controlled local-first app!

Basic examples


	/*
	|----------------------------|
	| Declare your database      |
	|----------------------------|
	*/

	const db = new Dexie('MyDatabase');

	// Declare tables, IDs and indexes
	db.version(1).stores({
		friends: '++id, name, age'
	});






					

	/*
	|-----------------------|
	| Then run some queries |
	|-----------------------|
	*/

	// Find some old friends
	const oldFriends = await db.friends
		.where('age').above(75)
		.toArray();

	// or make a new one
	await db.friends.add({
		name: 'Camilla',
		age: 25,
		street: 'East 13:th Street',
		picture: await getBlob('camilla.png')
	});

Live Queries

  import { useLiveQuery } from "dexie-react-hooks";
  import { db } from "./db";

  export function FriendList () {
    const friends = useLiveQuery(async () => {
      //
      // Query the DB using our promise based API.
      // The end result will magically become
      // observable.
      //
      return await db.friends
        .where("age")
        .between(18, 65)
        .toArray();
    });

    return <>
      <h2>Friends</h2>
      <ul>
        {
          friends?.map(friend =>
            <li key={friend.id}>
              {friend.name}, {friend.age}
            </li>
          )
        }
      </ul>

Sync

Turn on sync with a few simple steps:


1. Create your database in the cloud

1. Create your db in the cloud

npx dexie-cloud create

2. Whitelist your app origin(s)

npx dexie-cloud whitelist http://localhost:3000

3. Upgrade dexie + install dexie-cloud-addon

npm install dexie@latest
npm install dexie-cloud-addon

4. Update your DB declaration

  import Dexie from "dexie";
  import dexieCloud from "dexie-cloud-addon";

  const db = new Dexie('MySyncedDB', {addons: [dexieCloud]});

  db.version(1).stores({
    friends: '++id, name, age' // '++' = auto-incremented ID
    friends: '@id, name, age' // '@' = auto-generated global ID
  });

  db.cloud.configure({
    databaseUrl: "https://<yourdatabase>.dexie.cloud",
    requireAuth: true // (optional. Block DB until authenticated)
  });
