Directus JavaScript SDK

Features

TypeScript first: The SDK provides a robust and type-safe development experience.
Modular architecture: The SDK is split into separate modules, giving you granular control over which features to include and which can be pruned at build-time.
Lightweight and dependency-free: It does not require external libraries, ensuring a lighter bundle and streamlined experience.

Composable Client

The client is split up in separate features you can mix and match to compose a client with only the features you need or want.

const client = createDirectus<Schema>('https://api.directus.io');

const client = createDirectus<Schema>('https://api.directus.io');

This client is currently an empty wrapper without any functionality. Before you can do anything with it you'll need to add some features. The following composables are available/in progress:

rest() REST request functions
- adds .request(...) on the client
graphql() GraphQL request functions
- adds .query(...) on the client
staticToken() authentication functions
- adds .getToken() and .setToken() on the client
authenticate() authentication functions
- adds .login({ email, password }), .logout(), .refresh() on the client
- adds .getToken() and .setToken() on the client
realtime() websocket connectivity
- adds .subscribe(...), .sendMessage(...), .onWebsocket('message', (message) => {}) on the client

For this example we'll build a client including rest and graphql:

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(graphql());

// do a REST request
const restResult = await client.request(readItems('articles'));

// do a GraphQL request
const gqlResult = await client.query<OutputType>(`
    query {
        articles {
            id
            title
            author {
                first_name
            }
        }
    }
`);

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(graphql());

// do a REST request
const restResult = await client.request(readItems('articles'));

// do a GraphQL request
const gqlResult = await client.query<OutputType>(`
    query {
        articles {
            id
            title
            author {
                first_name
            }
        }
    }
`);

Authentication

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(authentication('json'));

await client.login('admin@example.com', 'd1r3ctu5');

// do authenticated requests

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(authentication('json'));

await client.login('admin@example.com', 'd1r3ctu5');

// do authenticated requests

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(staticToken('super-secure-token'));

// do authenticated requests

const client = createDirectus<Schema>('https://api.directus.io').with(rest()).with(staticToken('super-secure-token'));

// do authenticated requests

Real-Time

The realtime() extension allows you to work with a Directus REST WebSocket.

Subscribing to updates:

const client = createDirectus<Schema>('https://api.directus.io').with(
	realtime({
		authMode: 'public',
	}),
);

const { subscription, unsubscribe } = await client.subscribe('test', {
	query: { fields: ['*'] },
});

for await (const item of subscription) {
	console.log('subscription', { item });
}

// unsubscribe()

const client = createDirectus<Schema>('https://api.directus.io').with(
	realtime({
		authMode: 'public',
	}),
);

const { subscription, unsubscribe } = await client.subscribe('test', {
	query: { fields: ['*'] },
});

for await (const item of subscription) {
	console.log('subscription', { item });
}

// unsubscribe()

Receive/Send messages:

const client = createDirectus<Schema>('https://api.directus.io').with(
	realtime({
		authMode: 'public',
	}),
);

const stop = client.onWebSocket('message', (message) => {
	if ('type' in message && message['type'] === 'pong') {
		console.log('PONG received');
		stop();
	}
});

client.sendMessage({ type: 'ping' });

const client = createDirectus<Schema>('https://api.directus.io').with(
	realtime({
		authMode: 'public',
	}),
);

const stop = client.onWebSocket('message', (message) => {
	if ('type' in message && message['type'] === 'pong') {
		console.log('PONG received');
		stop();
	}
});

client.sendMessage({ type: 'ping' });

Build Your Schema

// The main schema type containing all collections available
interface MySchema {
	collection_a: CollectionA[]; // regular collections are array types
	collection_b: CollectionB[];
	collection_c: CollectionC; // this is a singleton
	// junction collections are collections too
	collection_a_b_m2m: CollectionAB_Many[];
	collection_a_b_m2a: CollectionAB_Any[];
}

// collection A
interface CollectionA {
	id: number;
	status: string;
	// relations
	m2o: number | CollectionB;
	o2m: number[] | CollectionB[];
	m2m: number[] | CollectionAB_Many[];
	m2a: number[] | CollectionAB_Any[];
}

// Many-to-Many junction table
interface CollectionAB_Many {
	id: number;
	collection_a_id: CollectionA;
	collection_b_id: CollectionB;
}

// Many-to-Any junction table
interface CollectionAB_Any {
	id: number;
	collection_a_id: CollectionA;
	collection: 'collection_b' | 'collection_c';
	item: string | CollectionB | CollectionC;
}

// collection B
interface CollectionB {
	id: number;
	value: string;
}

// singleton collection
interface CollectionC {
	id: number;
	app_settings: string;
	something: string;
}

// The main schema type containing all collections available
interface MySchema {
	collection_a: CollectionA[]; // regular collections are array types

}

// Many-to-Many junction table
