Seam HTTP client.

JavaScript HTTP client for the Seam API written in TypeScript.

Description

Seam makes it easy to integrate IoT devices with your applications. This is an official SDK for the Seam API. Please refer to the official Seam Docs to get started.

Parts of this SDK are generated from always up-to-date type information provided by @seamapi/types. This ensures all API methods, request shapes, and response shapes are accurate and fully typed.

The SDK contains minimal dependencies, is fully tree-shakeable, and optimized for use in both client and server applications. The underlying HTTP client is Axios.

Installation

Add this as a dependency to your project using npm with

$ npm install @seamapi/http
Copy

Usage

import { SeamHttp } from '@seamapi/http/connect'

const seam = new SeamHttp('your-api-key')
const devices = await seam.devices.list()
Copy

Authentication Methods

The SDK supports several authentication mechanisms. Authentication may be configured by passing the corresponding options directly to the SeamHttp constructor, or with the more ergonomic static factory methods.

Publishable Key authentication is not supported by the constructor and must be configured using SeamHttp.fromPublishableKey.

API Key

An API key is scoped to a single workspace and should only be used on the server. Obtain one from the Seam Console.

// Set the `SEAM_API_KEY` environment variable
const seam = new SeamHttp()

// Pass as the first argument to the constructor
const seam = new SeamHttp('your-api-key')

// Pass as an option the constructor
const seam = new SeamHttp({ apiKey: 'your-api-key' })

// Use the factory method
const seam = SeamHttp.fromApiKey('your-api-key')
Copy

Client Session Token

A Client Session Token is scoped to a client session and should only be used on the client.

// Pass as an option the constructor
const seam = new SeamHttp({ clientSessionToken: 'some-client-session-token' })

// Use the factory method
const seam = SeamHttp.fromClientSessionToken('some-client-session-token')
Copy

Publishable Key

A Publishable Key is used by the client to acquire Client Session Token for a workspace. Obtain one from the Seam Console.

Use the async factory method to return a client authenticated with a client session token:

const seam = await SeamHttp.fromPublishableKey(
  'your-publishable-key',
  'some-user-identifier-key',
)
Copy

This will get an existing client session matching the user identifier key, or create a new empty client session.

Personal Access Token

A Personal Access Token is scoped to a Seam Console user. Obtain one from the Seam Console. A workspace id must be provided when using this method and all requests will be scoped to that workspace.

// Pass as an option the constructor

const seam = new SeamHttp({
  personalAccessToken: 'your-personal-access-token',
  workspaceId: 'your-workspace-id',
})

// Use the factory method
const seam = SeamHttp.fromPersonalAccessToken(
  'some-console-session-token',
  'your-workspace-id',
)
Copy

Console Session Token

A Console Session Token is used by the Seam Console. This authentication method is only used by internal Seam applications. A workspace id must be provided when using this method and all requests will be scoped to that workspace.

// Pass as an option the constructor
const seam = new SeamHttp({
  consoleSessionToken: 'some-console-session-token',
  workspaceId: 'your-workspace-id',
})

// Use the factory method
const seam = SeamHttp.fromConsoleSessionToken(
  'some-console-session-token',
  'your-workspace-id',
)
Copy

Action Attempts

Some asynchronous operations, e.g., unlocking a door, return an action attempt. Seam tracks the progress of requested operation and updates the action attempt.

To make working with action attempts more convenient for applications, this library provides the resolveActionAttempt function:

• Polls the action attempt up to the timeout at the pollingInterval (both in milliseconds).
• Resolves with a fresh copy of the successful action attempt.
• Rejects with a SeamActionAttemptFailedError if the action attempt is unsuccessful.
• Rejects with a SeamActionAttemptTimeoutError if the action attempt is still pending when the timeout is reached.
• Both errors expose an actionAttempt property.

import {
  SeamHttp,
  resolveActionAttempt,
  isSeamActionAttemptFailedError,
  isSeamActionAttemptTimeoutError,
} from '@seamapi/http/connect'

const seam = new SeamHttp('your-api-key')

const [lock] = await seam.locks.list()

if (lock == null) throw new Error('No locks in this workspace')

const actionAttempt = await seam.locks.unlockDoor({
  device_id: lock.device_id,
})

try {
  await resolveActionAttempt(actionAttempt, seam)
} catch (err: unknown) {
  if (isSeamActionAttemptFailedError(err)) {
    console.log('Could not unlock the door')
    return
  }

  if (isSeamActionAttemptTimeoutError(err)) {
    console.log('Door took too long to unlock')
    return
  }

  throw err
}
Copy

Advanced Usage

In addition the various authentication options, the constructor takes some additional options that affect behavior.

const seam = new SeamHttp({
  apiKey: 'your-api-key',
  endpoint: 'https://example.com',
  axiosOptions: {},
  axiosRetryOptions: {},
})
Copy

When using the static factory methods, these options may be passed in as the last argument.

const seam = SeamHttp.fromApiKey('some-api-key', {
  endpoint: 'https://example.com',
  axiosOptions: {},
  axiosRetryOptions: {},
})
Copy

Setting the endpoint

Some contexts may need to override the API endpoint, e.g., testing or proxy setups. This option corresponds to the Axios baseURL setting.

Either pass the endpoint option, or set the SEAM_ENDPOINT environment variable.

Configuring the Axios Client

The Axios client and retry behavior may be configured with custom initiation options via [axiosOptions] and axiosRetryOptions. Options are deep merged with the default options.

Using the Axios Client

The Axios client is exposed and may be used or configured directly:

import { SeamHttp, DevicesListResponse } from '@seamapi/http/connect'

const seam = new SeamHttp()

seam.client.interceptors.response.use((response) => {
  console.log(response)
  return response
})

const devices = await seam.client.get<DevicesListResponse>('/devices/list')
Copy

Overriding the Client

An Axios compatible client may be provided to create a SeamHttp instance. This API is used internally and is not directly supported.

Development and Testing

Quickstart

$ git clone https://github.com/seamapi/javascript-http.git
$ cd javascript-http
$ nvm install
$ npm install
$ npm run test:watch
Copy

Primary development tasks are defined under scripts in package.json and available via npm run. View them with

$ npm run
Copy

Source code

The source code is hosted on GitHub. Clone the project with

$ git clone git@github.com:seamapi/javascript-http.git
Copy

Requirements

You will need Node.js with npm and a Node.js debugging client.

Be sure that all commands run under the correct Node version, e.g., if using nvm, install the correct version with

$ nvm install
Copy

Set the active version for each shell session with

$ nvm use
Copy

Install the development dependencies with

$ npm install
Copy

Publishing

Automatic

New versions are released automatically with semantic-release as long as commits follow the Angular Commit Message Conventions.

Manual

Publish a new version by triggering a version workflow_dispatch on GitHub Actions. The version input will be passed as the first argument to npm-version.

This may be done on the web or using the GitHub CLI with

$ gh workflow run version.yml --raw-field version=<version>
Copy

GitHub Actions

GitHub Actions should already be configured: this section is for reference only.

The following repository secrets must be set on GitHub Actions:

• NPM_TOKEN: npm token for installing and publishing packages.
• GH_TOKEN: A personal access token for the bot user with packages:write and contents:write permission.
• GIT_USER_NAME: The GitHub bot user's real name.
• GIT_USER_EMAIL: The GitHub bot user's email.
• GPG_PRIVATE_KEY: The GitHub bot user's GPG private key.
• GPG_PASSPHRASE: The GitHub bot user's GPG passphrase.
