JavaScript SDK

The JS SDK provides an intuitive interface for the Directus API from within a JavaScript-powered project (browsers and Node.js). The default implementation uses Axios for transport and localStorage for storing state. Advanced customizations are available.

Installation

bash
npm install @directus/sdk

Basic Usage

This is the starting point to use the JS SDK. After you've created the Directus instance, you can start invoking methods from it to access your project and data.

js
import { Directus } from '@directus/sdk';

const directus = new Directus('http://directus.example.com');

You can always access data available to the public role.

js
async function publicData() {
	// GET DATA

	// We don't need to authenticate if the public role has access to some_public_collection.
	const publicData = await directus.items('some_public_collection').readByQuery({ sort: ['id'] });

	console.log(publicData.data);
}

Basic Authentication

To access anything that is not available to the public role, you must be authenticated.

js
async function start() {
	// AUTHENTICATION

	let authenticated = false;

	// Try to authenticate with token if exists
	await directus.auth
		.refresh()
		.then(() => {
			authenticated = true;
		})
		.catch(() => {});

	// Let's login in case we don't have token or it is invalid / expired
	while (!authenticated) {
		const email = window.prompt('Email:');
		const password = window.prompt('Password:');

		await directus.auth
			.login({ email, password })
			.then(() => {
				authenticated = true;
			})
			.catch(() => {
				window.alert('Invalid credentials');
			});
	}

	// GET DATA

	// After authentication, we can fetch data from any collections that the user has permissions to.
	const privateData = await directus.items('some_private_collection').readByQuery({ sort: ['id'] });

	console.log(publicData.data);
}

start();

Custom Configuration

The previous section covered basic installation and usage of the JS SDK with default configurations for init. But sometimes you may need to customize these defaults.

Constructor

js
import { Directus } from '@directus/sdk';

const directus = new Directus(url, init);

Parameters


url required

  • TypeString
  • Description — A string that points to your Directus instance. E.g., https://example.directus.io
  • Default — N/A

init optional

  • TypeObject
  • Description — Defines authentication, storage and transport settings.
  • Default — The following shows the default values for init.
js
// This is the default init object
const config = {
	auth: {
		mode: 'cookie', // 'json' in Node.js
		autoRefresh: true,
		msRefreshBeforeExpires: 30000,
		staticToken: '',
	},
	storage: {
		prefix: '',
		mode: 'LocalStorage', // 'MemoryStorage' in Node.js
	},
	transport: {
		params: {},
		headers: {},
		onUploadProgress: (ProgressEvent) => {},
		maxBodyLength: null,
		maxContentLength: null,
	},
};

Customize auth

Defines how authentication is handled by the SDK. By default, Directus creates an instance of auth which handles refresh tokens automatically.

js
const auth = {
	mode: 'cookie', // 'json' in Node.js
	autoRefresh: true,
	msRefreshBeforeExpires: 30000,
	staticToken: '',
};

Options


mode

  • TypeString
  • Description — Defines the mode you want to use for authentication. It can be 'cookie' for cookies or 'json' for JWT.
  • Default — Defaults to 'cookie' on browsers and 'json' otherwise.

TIP

We recommend using cookies when possible to prevent any kind of attacks, mostly XSS.

autoRefresh

  • TypeBoolean
  • Description — Determines whether SDK handles refresh tokens automatically.
  • Default — Defaults to true.

msRefreshBeforeExpires

  • TypeNumber
  • Description — When autoRefresh is enabled, this tells how many milliseconds before the refresh token expires and needs to be refreshed.
  • Default — Defaults to 30000.

staticToken

  • TypeString
  • Description - Defines the static token to use. It is not compatible with the options above since it does not refresh.
  • Default — Defaults to '' (no static token).

Extend auth

It is possible to provide a custom implementation by extending IAuth. While this could be useful in certain advanced situations, it is not needed for most use-cases.

js
import { IAuth, Directus } from '@directus/sdk';

class MyAuth extends IAuth {
	async login() {
		return { access_token: '', expires: 0 };
	}
	async logout() {}
	async refresh() {
		return { access_token: '', expires: 0 };
	}
	async static() {
		return true;
	}
}

const directus = new Directus('https://example.directus.app', {
	auth: new MyAuth(),
});

Customize storage

The storage is used to load and save token information. By default, Directus creates an instance of storage which handles store information automatically.

js
const storage = {
	prefix: '',
	mode: 'LocalStorage', // 'MemoryStorage' in Node.js
};

Multiple Instances

If you want to use multiple instances of the SDK you should set a different prefix for each one.

TIP

The axios instance can be used for custom requests by calling:

ts
await directus.transport.<method>('/path/to/endpoint', {
	/* body, params, ... */
});

Options


prefix

  • TypeString
  • Description — Defines the tokens prefix tokens that are saved. This should be fulfilled with different values when using multiple instances of SDK.
  • Default — Defaults to '' (no prefix).

mode

  • TypeString
  • Description — Defines the storage location to be used to save tokens. Allowed values are LocalStorage and MemoryStorage. The mode LocalStorage is not compatible with Node.js. MemoryStorage is not persistent, so once you leave the tab or quit the process, you will need to authenticate again.
  • Default — Defaults to LocalStorage on browsers and MemoryStorage on Node.js.

Extend storage

It is possible to provide a custom implementation by extending BaseStorage. While this could be useful in certain advanced situations, it is not needed for most use-cases.

js
import { BaseStorage, Directus } from '@directus/sdk';

class SessionStorage extends BaseStorage {
	get(key) {
		return sessionStorage.getItem(key);
	}
	set(key, value) {
		return sessionStorage.setItem(key, value);
	}
	delete(key) {
		return sessionStorage.removeItem(key);
	}
}

const directus = new Directus('https://example.directus.app', {
	storage: new SessionStorage(),
});

Customize transport

Defines settings you want to customize regarding Transport.

By default, Directus creates an instance of Transport which handles requests automatically. It uses axios so it is compatible in both browsers and Node.js. With axios, it is also possible to handle upload progress (a downside of fetch).

The configurations within init.transport are passed to axios. For more details, see Request Config in the axios documentation.

js
export default {
	params: {},
	headers: {},
	onUploadProgress: (ProgressEvent) => {},
	maxBodyLength: null,
	maxContentLength: null,
};

Options


params

  • TypeObject
  • Description — Defines an object with keys and values to be passed as additional query string.
  • Default — N/A

headers

  • TypeObject
  • Description - Defines an object with keys and values to be passed as additional headers.
  • Default — N/A

onUploadProgress

  • TypeFunction
  • Description — Defines a callback function to indicate the upload progress.
  • Default — N/A

ProgressEvent Please see the MDN documentation to learn more about the

ProgressEvent.


maxBodyLength

  • TypeNumber
  • Description — The maximum body length in bytes. Set Infinity for no limit.
  • Default — N/A

maxContentLength

  • TypeNumber
  • Description — The maximum content length in bytes. Set Infinity for no limit.
  • Default — N/A

Extend Transport

It is possible to provide a custom implementation by extending ITransport. For example, you can customize it to use different HTTP libraries. While this could be useful in certain advanced situations, it is not needed for most use-cases.

js
import { ITransport, Directus } from '@directus/sdk';

class MyTransport extends ITransport {
	buildResponse() {
		return {
			raw: '',
			data: {},
			status: 0,
			headers: {},
		};
	}

	async get(path, options) {
		return this.buildResponse();
	}
	async head(path, options) {
		return this.buildResponse();
	}
	async options(path, options) {
		return this.buildResponse();
	}
	async delete(path, data, options) {
		return this.buildResponse();
	}
	async post(path, data, options) {
		return this.buildResponse();
	}
	async put(path, data, options) {
		return this.buildResponse();
	}
	async patch(path, data, options) {
		return this.buildResponse();
	}
}

const directus = new Directus('https://example.directus.app', {
	transport: new MyTransport(),
});

TypeScript

Version >= 4.1

Although it's not required, it is recommended to use TypeScript to have an easy development experience. This allows more detailed IDE suggestions for return types, sorting, filtering, etc.

To feed the SDK with your current schema, you need to pass it on the constructor.

ts
type BlogPost = {
	id: ID;
	title: string;
};

type BlogSettings = {
	display_promotions: boolean;
};

type MyCollections = {
	posts: BlogPost;
	settings: BlogSettings;
};

// This is how you feed custom type information to Directus.
const directus = new Directus<MyCollections>('https://example.directus.app');

// ...

const post = await directus.items('posts').readOne(1);
// typeof(post) is a partial BlogPost object

const settings = await posts.singleton('settings').read();
// typeof(settings) is a partial BlogSettings object

You can also extend the Directus system type information by providing type information for system collections as well.

ts
import { Directus } from '@directus/sdk';

// Custom fields added to Directus user collection.
type UserType = {
	level: number;
	experience: number;
};

type CustomTypes = {
	/*
	This type will be merged with Directus user type.
	It's important that the naming matches a directus
	collection name exactly. Typos won't get caught here
	since SDK will assume it's a custom user collection.
	*/
	directus_users: UserType;
};

const directus = new Directus<CustomTypes>('https://example.directus.app');

await directus.auth.login({
	email: 'admin@example.com',
	password: 'password',
});

const me = await directus.users.me.read();
// typeof me = partial DirectusUser & UserType;

// OK
me.level = 42;

// Error TS2322: Type "string" is not assignable to type "number".
me.experience = 'high';

Authentication

Get current token

ts
const token = await directus.auth.token;

Async

Reading the token is an asynchronous getter. This makes sure that any currently active refresh calls are being awaited before the current token is returned.

Login

With credentials

js
await directus.auth.login({
	email: 'admin@example.com',
	password: 'd1r3ctu5',
});

With static tokens

js
await directus.auth.static('static_token');

Refresh Auth Token

By default, Directus will handle token refreshes. Although, you can handle this behavior manually by setting autoRefresh to false.

js
await directus.auth.refresh();

Developing Locally

If you're developing locally, you might not be able to refresh your auth token automatically in all browsers. This is because the default auth configuration requires secure cookies to be set, and not all browsers allow this for localhost. You can use a browser which does support this such as Firefox, or disable secure cookies.

Logout

js
await directus.auth.logout();

Request a Password Reset

By default, the address defined in PUBLIC_URL on .env file is used for the link to the reset password page sent in the email:

js
await directus.auth.password.request('admin@example.com');

But a custom address can be passed as second argument:

js
await directus.auth.password.request(
	'admin@example.com',
	'https://myapp.com' // In this case, the link will be https://myapp.com?token=FEE0A...
);

Note: To use a custom address you need to configure the PASSWORD_RESET_URL_ALLOW_LIST environment variable to enable this feature.

Reset a Password

js
await directus.auth.password.reset('abc.def.ghi', 'n3w-p455w0rd');

Note: The token passed in the first parameter is sent in an email to the user when using request()

Items

You can get an instance of the item handler by providing the collection (and type, in the case of TypeScript) to the items function. The following examples will use the Article type.

JavaScript

js
// import { Directus, ID } from '@directus/sdk';
const { Directus } = require('@directus/sdk');

const directus = new Directus('https://example.directus.app');

const articles = directus.items('articles');

TypeScript

ts
import { Directus, ID } from '@directus/sdk';

// Map your collection structure based on its fields.
type Article = {
	id: ID;
	title: string;
	body: string;
	published: boolean;
};

// Map your collections to its respective types. The SDK will
// infer its types based on usage later.
type MyBlog = {
	// [collection_name]: typescript_type
	articles: Article;

	// You can also extend Directus collection. The naming has
	// to match a Directus system collection and it will be merged
	// into the system spec.
	directus_users: {
		bio: string;
	};
};

// Let the SDK know about your collection types.
const directus = new Directus<MyBlog>('https://example.directus.app');

// typeof(article) is a partial "Article"
const article = await directus.items('articles').readOne(10);

// Error TS2322: "hello" is not assignable to type "boolean".
// post.published = 'hello';

Create Single Item

js
await articles.createOne({
	title: 'My New Article',
});

Create Multiple Items

js
await articles.createMany([
	{
		title: 'My First Article',
	},
	{
		title: 'My Second Article',
	},
]);

js
await articles.readByQuery({
	search: 'Directus',
	filter: {
		date_published: {
			_gte: '$NOW',
		},
	},
});

Read All

js
await articles.readByQuery({
	// By default API limits results to 100.
	// With -1, it will return all results, but it may lead to performance degradation
	// for large result sets.
	limit: -1,
});

Read Single Item

js
await articles.readOne(15);

Supports optional query:

js
await articles.readOne(15, {
	fields: ['title'],
});

Read Multiple Items

js
await articles.readMany([15, 16, 17]);

Supports optional query:

js
await articles.readMany([15, 16, 17], {
	fields: ['title'],
});

Update Single Item

js
await articles.updateOne(15, {
	title: 'This articles now has a different title',
});

Supports optional query:

js
await articles.updateOne(
	42,
	{
		title: 'This articles now has a similar title',
	},
	{
		fields: ['title'],
	}
);

Update Multiple Items

js
await articles.updateMany([15, 42], {
	title: 'Both articles now have the same title',
});

Supports optional query:

js
await articles.updateMany(
	[15, 42],
	{
		title: 'Both articles now have the same title',
	},
	{
		fields: ['title'],
	}
);

Delete

js
// One
await articles.deleteOne(15);

// Multiple
await articles.deleteMany([15, 42]);

Request Parameter Overrides

To override any of the axios request parameters, provide an additional parameter with a requestOptions object:

js
await articles.createOne(
	{ title: 'example' },
	{ fields: ['id'] },
	{
		requestOptions: {
			headers: {
				'X-My-Custom-Header': 'example',
			},
		},
	}
);

Activity

js
directus.activity;

Same methods as directus.items("directus_activity").

Comments

js
directus.comments;

Same methods as directus.items("directus_comments").

Collections

js
directus.collections;

Same methods as directus.items("directus_collections").

Fields

js
directus.fields;

Same methods as directus.items("directus_fields").

Files

js
directus.files;

Same methods as directus.items("directus_files").

Uploading a file

To upload a file you will need to send a multipart/form-data as body. On browser side you do so:

js
/* index.js */
import { Directus } from 'https://unpkg.com/@directus/sdk@latest/dist/sdk.esm.min.js';

const directus = new Directus('https://example.directus.app', {
	auth: {
		staticToken: 'STATIC_TOKEN', // If you want to use a static token, otherwise check below how you can use email and password.
	},
});

// await directus.auth.login({ email, password })
// If you want to use email and password, remove the staticToken above.

const form = document.querySelector('#upload-file');

if (form && form instanceof HTMLFormElement) {
	form.addEventListener('submit', async (event) => {
		event.preventDefault();

		const form = new FormData(event.target);
		await directus.files.createOne(form);
	});
}
html
<!-- index.html -->
<head></head>
<body>
	<form id="upload-file">
		<input type="text" name="title" />
		<input type="file" name="file" />
    	<button>Send</button>
	</form>
	<script src="/index.js" type="module"></script>
</body>
</html>

NodeJS usage

When uploading a file from a NodeJS environment, you'll have to override the headers to ensure the correct boundary is set:

js
import { Directus } from 'https://unpkg.com/@directus/sdk@latest/dist/sdk.esm.min.js';

const directus = new Directus('https://example.directus.app', {
	auth: {
		staticToken: 'STATIC_TOKEN', // If you want to use a static token, otherwise check below how you can use email and password.
	},
});

const form = new FormData();
form.append("file", fs.createReadStream("./to_upload.jpeg"));

const fileId = await directus.files.createOne(form, {}, {
  requestOptions: {
    headers: {
      ...form.getHeaders()
    }
  }
);

Importing a file

Example of importing a file from a URL:

js
await directus.files.import({
	url: 'http://www.example.com/example-image.jpg',
});

Example of importing file with custom data:

js
await directus.files.import({
	url: 'http://www.example.com/example-image.jpg',
	data: {
		title: 'My Custom File',
	},
});

The provided token is sent to the user's email

Enable Two-Factor Authentication

js
await directus.users.tfa.enable('my-password');

Disable Two-Factor Authentication

js
await directus.users.tfa.disable('691402');

Get the Current User

js
await directus.users.me.read();

Sort Items in a Collection

js
await directus.utils.sort('articles', 15, 42);

This will move item 15 to the position of item 42, and move everything in between one "slot" up.

Revert to a Previous Revision

js
await directus.utils.revert(451);

Note: The key passed is the primary key of the revision you'd like to apply.
