@cadolabs/auther-client ·

A frontend client for working with the Auther gem.

Getting Started

Installation

npm i @cadolabs/auther-client

or

yarn add @cadolabs/auther-client

Configure

Create an AutherClient instance before initializing your application.

import { AutherClient } from "@cadolabs/auther-client"

const auth = AutherClient.init({
  autherUrl: "<AUTHER_DOMAIN>",
  redirectUri: "<CALLBACK_URL>",
  appcode: "<APP_CODE>", // your app unique id
})

Usage

Logging In

To redirect to the auther login

auth.login()

And after that you redirect to the callback route <CALLBACK_URL> with query string authorization_code="12345".

Get tokens

//async/await
try {
  const authorizationCode = "12345"

  const response = await auth.fetchTokens(authorizationCode) // return Promise
  const tokens = response.json()

  const { accessToken, refreshToken } = tokens
  ...
} catch (error) {
  throw Error(error.message) // invalid.authorization_code
}

Update tokens

const refreshToken = "refresh_token"

//async/await
try {
  const response = await auth.updateTokens(refreshToken) // return Promise
  const tokens = response.json()

  const { accessToken, refreshToken } = tokens
} catch (error) {
  throw Error(error.message) // invalid.access_token
}

Loggout In

To make a request to revoke tokens

const accessToken = "access_token"

//async/await
try {
  await auth.logout(accessToken)
  ...
} catch (error) {
  throw Error(error.message) // invalid.access_token
}

Authentication

Authentication method for verifying access and refresh tokens and scheduling tokens refreshing.

const getTokens = () => {
  const accessToken = localStorage.getItem("accessToken")
  const refreshToken = localStorage.getItem("refreshToken")

  return { accessToken, refreshToken }
}

const saveTokens = ({ accessToken, refreshToken }) => {
  localStorage.setItem("accessToken", accessToken)
  localStorage.setItem("refreshToken", refreshToken)
}

//async/await
try {
  await auth.authentication({ getTokens, saveTokens })
  ...
} catch (error) {
  throw Error(error.message) // token.not_found
}

Additional usage

Decode token

To decode the token

import { decode } from "@cadolabs/auther-client"

const testToken = "eyJhbGc*.NHVaY*.i8ZJd8_-RU8V" // headers.payload.signature

const decodedToken = decode(testToken)

console.log(decodedToken)

/* console prints:
 * {
 *   header: {
 *     alg: "RS256",
 *     typ: "JWT"
 *   },
 *   payload: {
 *     sub: "1234567890",
 *     name: "John Doe",
 *     iat: 1516239022,
 *     exp: 1516239022,
 * },
 *   signature: "i8ZJd8_-RU8V",
 * }
*/

Return the decoded object with parameters

Verify token

Checks the token for errors or expired time. If there are no problems, return it back

import { verify } from "@cadolabs/auther-client"

const testToken = "eyJhbGc*.NHVaY*.i8ZJd8_-RU8V" // headers.payload.signature

try {
  const verifiedToken = verify(testToken)

  console.log(verifiedToken)

  /* console prints if no problems:
  * "eyJhbGc*.NHVaY*.i8ZJd8_-RU8V"
  */
} catch (error) {
  console.log(error.message)
  /* console prints if token is expired:
  * "token.expired"
  */
}
