casdoor-js-sdk

This is Casdoor's SDK for js will allow you to easily connect your application to the Casdoor authentication system without having to implement it from scratch.

Casdoor SDK is very simple to use. We will show you the steps below.

Usage in NPM environment

Installation

# NPM
npm i casdoor-js-sdk


# Yarn
yarn add casdoor-js-sdk

Init SDK

Initialization requires 5 parameters, which are all string type:

Name (in order)	Must	Description
serverUrl	Yes	your Casdoor server URL
clientId	Yes	the Client ID of your Casdoor application
appName	Yes	the name of your Casdoor application
organizationName	Yes	the name of the Casdoor organization connected with your Casdoor application
redirectPath	No	the path of the redirect URL for your Casdoor application, will be /callback if not provided
signinPath	No	the path of the signin URL for your Casdoor application, will be /api/signin if not provided

import {SDK, SdkConfig} from 'casdoor-js-sdk'

const sdkConfig: SdkConfig = {
    serverUrl: "https://door.casbin.com",
    clientId: "014ae4bd048734ca2dea",
    appName: "app-casnode",
    organizationName: "casbin",
    redirectPath: "/callback",
    signinPath: "/api/signin",
}
const sdk = new SDK(sdkConfig)
// call sdk to handle

Usage in vanilla Javascript

Import and init SDK

Initialization parameters are consistent with the previous node.js section:

<!--init the SDK-->
<script type="module">
  //Import from cdn(you can choose the appropriate cdn source according to your needs), or just from the local(download the casdoor-js-sdk first)
  import SDK from 'https://unpkg.com/casdoor-js-sdk@latest/lib/esm/sdk.js'
  const sdkConfig = {
    serverUrl: "https://door.casbin.com",
    clientId: "014ae4bd048734ca2dea",
    appName: "app-casnode",
    organizationName: "casbin",
    redirectPath: "/callback",
    signinPath: "/api/signin",
  }
  window.sdk = new SDK(sdkConfig)
</script>

Call functions in SDK

<script type="text/javascript">
  function gotoSignUpPage() {
    window.location.href = sdk.getSigninUrl()
  }
</script>

API reference interface

Get sign up url

getSignupUrl(enablePassword)

Return the casdoor url that navigates to the registration screen

Get sign in url

getSigninUrl()

Return the casdoor url that navigates to the login screen

Get user profile page url

getUserProfileUrl(userName, account)

Return the url to navigate to a specific user's casdoor personal page

Get my profile page url

getMyProfileUrl(account)

Sign in

signin(serverUrl, signinPath)

Handle the callback url from casdoor, call the back-end api to complete the login process

Determine whether silent sign-in is being used

isSilentSigninRequested()

We usually use this method to determine if silent login is being used. By default, if the silentSignin parameter is included in the URL and equals one, this method will return true. Of course, you can also use any method you prefer.

silentSignin

silentSignin(onSuccess, onFailure)

First, let's explain the two parameters of this method, which are the callback methods for successful and failed login. Next, I will describe the execution process of this method. We will create a hidden "iframe" element to redirect to the login page for authentication, thereby achieving the effect of silent sign-in.
