Huly Platform API Client

A TypeScript client library for interacting with the Huly Platform API.

Installation

In order to be able to install required packages, you will need to obtain GitHub access token. You can create a token by following the instructions here.

npm install @hcengineering/api-client

WebSocket Client vs REST Client

The api client package provides two main client variants: a WebSocket client and a REST client. The WebSocket client holds persistent connection to the Huly Platform API. The REST client uses standard HTTP requests to perform operations.

WebSocket Client

import { connect } from '@hcengineering/api-client'

// Connect to Huly
const client = await connect('https://huly.app', {
  email: '[email protected]',
  password: 'password',
  workspace: 'my-workspace',
})

// Use the client to perform operations
...

// Close the client when done
await client.close()

REST Client

import { connectRest } from '@hcengineering/api-client'

// Connect to Huly
const client = await connectRest('https://huly.app', {
  email: '[email protected]',
  password: 'password',
  workspace: 'my-workspace'
})

// Use the client to perform operations
...

Authentication

The client supports two authentication methods: using email and password, or using a token. When authenticated, the client will have access to the same resources as the user.

Note: The examples below use the WebSocket client (connect). To use the REST client instead, import and call connectRest with the same options.

Parameters:

• url: URL of the Huly instance, for Huly Cloud use https://huly.app
• options: Connection options
  • workspace: Name of the workspace to connect to, the workspace name can be found in the URL of the workspace: https://huly.app/workbench/<workspace-name>
  • token: Optional authentication token
  • email: Optional user email
  • password: Optional user password

Using Email and Password

import { connect } from '@hcengineering/api-client'

const client = await connect('https://huly.app', {
  email: '[email protected]',
  password: 'password',
  workspace: 'my-workspace'
})

...

await client.close()

Using Token

import { connect } from '@hcengineering/api-client'

const client = await connect('https://huly.app', {
  token: '...',
  workspace: 'my-workspace'
})

...

await client.close()

Client API

The client provides a set of methods for interacting with the Huly Platform API. This section describes the main methods available in the client.

Fetch API

The client provides two main methods for retrieving documents: findOne and findAll.

findOne

Retrieves a single document matching the query criteria.

Parameters:

• _class: Class of the object to find, results will include all subclasses of the target class
• query: Query criteria
• options: Find options
  • limit: Limit the number of results returned
  • sort: Sorting criteria
  • lookup: Lookup criteria
  • projection: Projection criteria
  • total: If specified total will be returned

Example:

import contact from '@hcengineering/contact'

...

const person = await client.findOne(
  contact.class.Person,
  {
    _id: 'person-id'
  }
)

findAll

Retrieves multiple document matching the query criteria.

Parameters:

• _class: Class of the object to find, results will include all subclasses of the target class
• query: Query criteria
• options: Find options
  • limit: Limit the number of results returned

  • projection: Projection criteria
  • total: If specified total will be returned

Example:

import { SortingOrder } from '@hcengineering/core'

    limit: 10,
    sort: {
      name: SortingOrder.Ascending

..

const personId = await client.createDoc(
  contact.class.Person,
  contact.space.Contacts,
  {
    name: 'Doe,John',
    city: 'New York',
    avatarType: AvatarType.COLOR
  }
)

  {
    city: 'New York',
  }
)
