Javascript

The @propelauth/javascript library is designed for any frontend application. While you should prefer a more specific framework, like React, whenever possible, this library has been used in applications with Svelte, Angular, Vue, and more.

Installation and Usage

npm install @propelauth/javascript

and then you can import it:

import { createClient } from "@propelauth/javascript";

Alternatively, you can use a CDN:

<script 
    src="https://www.unpkg.com/@propelauth/javascript@2.0.11/dist/javascript.min.js" 
    integrity="sha384-FENNH2f7QuQvkZJBL7jebLr0OtYKgTA2iq+C5g3VXXX7SBwWmeMMoc+pBBtcn76G" 
    crossorigin="anonymous"></script>

then a global PropelAuth object will be created, and you can call createClient from it:

<script>
  PropelAuth.createClient({...});
</script>

Using the Javascript library

You'll create a client using the createClient function, and then you can use the client to get information about the current user.

You can also enabled background token refresh, which will automatically refresh the user's information periodically and on key events (e.g. user switches tabs, reconnects to the internet, etc).

createClient

Creates an authentication client which manages your user's access token, fetches user information, and provides other useful authentication functions.

The client also refreshes auth information when a user switches focus to your tab or reconnects (if they were offline).

const authClient = createClient({
  // The base URL where your authentication pages are hosted.
  // You can find this under the Frontend Integration section for your project.
  authUrl: "https://auth.yourdomain.com",

  // If true, periodically refresh the access token in the background.
  // This helps ensure you always have a valid token ready to go. Default true.
  enableBackgroundTokenRefresh: true,
});

getAuthenticationInfoOrNull

If the user is logged in, this method returns an AuthenticationInfo object with information about the user. Otherwise, this method returns null.

The promise will generally resolve immediately, unless our current information is stale in which case it will make an API request.

Arguments

Name
forceRefresh
Type
boolean
Description
If true, the client will make an API request to get the latest information. Otherwise, it will use the cached information if it is still valid.

import {createClient} from "@propelauth/javascript"
const authClient = createClient({...})

const authInfo = await authClient.getAuthenticationInfoOrNull()
if (authInfo) {
    console.log("User is logged in as", authInfo.user.email)
} else {
    console.log("User is not logged in")
}
