createClient

createClient(options) creates a new CloudAuthClient for the application with appId.

import { createClient } from '@featherscloud/auth'

const appId = '<your-app-id>'
const auth = createClient({ appId })

LoginRequiredError

This error is thrown when the client requires a user login and usually used to put together the URL for the login page:

import { LoginRequiredError } from '@featherscloud/auth'

try {
  const authorizationHeader = await auth.getHeader()
}
catch (error: unknown) {
  if (error instanceof LoginRequiredError) {
    // Redirect to the login page
    window.location.href = await auth.getLoginUrl(error)
  }
  else {
    throw error
  }
}

CloudAuthClient

options

appId - The application id
store (default: IndexedDb) - The storage for device information and access tokens.
loginExpiry (default: 15 minutes) - The time (in seconds) a login request expires. Can not be more than 15 minutes.
deviceId (optional) - Initialize with this device (instead of the default first one)

getAccessToken

auth.getAccessToken() returns the access token for the user. Will throw a LoginRequiredError if the user needs to log in for this device.

getHeader

auth.getHeaders() returns the Authorization header for the current user in the required form of Bearer <accessToken>.

getLoginUrl

auth.getLoginUrl(error) returns the URL for the login page when a LoginRequiredError happened.

logout

auth.logout() logs the user out but remembers their device so their information is pre-filled the next time they log in.

logoutAndForget

auth.logoutAndForget() logs the user out and deletes this device.

listDevices

auth.listDevices() lists all devices in the store. This can be used to handle account switching.

createDevice

auth.createDevice() creates a new devices and sets it as the currently used device. This will require a user to log in before they can make any requests.

getDevice

auth.getDevice() returns the information (like the device id and linked user) for the current device.

setDevice

auth.setDevice(deviceId) sets the currently used device (usually retrieved from auth.listDevices()).

createVerifier

createVerifier({ appId }) creates a verifier for the application id. It does not need any additional information, works offline and does not make any external requests.

import { createVerifier } from '@featherscloud/auth'

const appId = '<your-app-id>'
const verifier = createVerifier({ appId })
