⚡ Quickstart

This Quickstart guide will help you get started with WSO2 Thunder quickly. It walks you through downloading and running the product, trying out the sample app, and exploring registering a user, logging in, and using the Client Credentials flow.

Download and Run WSO2 Thunder

You can run WSO2 Thunder either by downloading the release artifact or using the official Docker image.

Option 1: Run from Release Artifact

Follow these steps to download the latest release of WSO2 Thunder and run it locally.

1. Download the distribution from the latest release

   Download thunder-<version>-<os>-<arch>.zip from the latest release for your operating system and architecture.

   For example, if you are using a MacOS machine with a Apple Silicon (ARM64) processor, you would download thunder-<version>-macos-arm64.zip.

2. Unzip the product

   Unzip the downloaded file using the following command:

   unzip thunder-<version>-<os>-<arch>.zip
   

   Navigate to the unzipped directory:

   cd thunder-<version>-<os>-<arch>/
   

3. Setup the product

   You need to setup the server with the initial configurations and data before starting the server for the first time.

   If you are using a Linux or macOS machine:

   ./setup.sh
   

   If you are using a Windows machine:

   .\setup.ps1
   

   Note the id of the sample app indicated with the log line [INFO] Sample App ID: <id>. You'll need it for the sample app configuration.

4. Start the product

   If you are using a Linux or macOS machine:

   ./start.sh
   

   If you are using a Windows machine:

   .\start.ps1
   

   The product will start on https://localhost:8090.

Option 2: Run with Docker Compose

Follow these steps to run WSO2 Thunder using Docker Compose.

1. Download the Docker Compose file

   Download the docker-compose.yml file using the following command:

   curl -o docker-compose.yml https://raw.githubusercontent.com/asgardeo/thunder/v0.33.0/install/quick-start/docker-compose.yml
   

2. Start Thunder

   Run the following command in the directory where you downloaded the docker-compose.yml file:

   docker compose up
   

   This will automatically:

   • Initialize the database
   • Run the setup process
   • Start the Thunder server

   Note the id of the sample app indicated with the log line [INFO] Sample App ID: <id> in the setup logs. You'll need it for the sample app configuration.

   The product will start on https://localhost:8090.

Try Out the Product

Try out the Thunder Console

Follow these steps to access the Thunder Console:

1. Open your browser and navigate to https://localhost:8090/console.

2. Log in using the admin credentials created during the initial data setup (admin / admin).

Try Out with the Sample App

Thunder provides two sample applications to help you get started quickly:

• React Vanilla Sample — Sample React application demonstrating direct API integration without external SDKs. Supports Native Flow API or Standard OAuth/OIDC.
• React SDK Sample — Sample React application demonstrating SDK-based integration using @asgardeo/react for OAuth 2.0/OIDC authentication.

React Vanilla Sample

1. Download the sample

   Download sample-app-react-vanilla-<version>-<os>-<arch>.zip from the latest release.

2. Unzip and navigate to the sample app directory

   unzip sample-app-react-vanilla-<version>-<os>-<arch>.zip
   cd sample-app-react-vanilla-<version>-<os>-<arch>/
   

3. Configure the sample

   Open app/runtime.json and set the applicationID to the sample app ID generated during "Setup the product":

   {
       "applicationID": "{your-application-id}"
   }
   

4. Start the sample

   ./start.sh
   

   Open your browser and navigate to https://localhost:3000 to access the sample app.

   📖 Refer to the README.md inside the extracted sample app for detailed configuration options including OAuth redirect-based login.

React SDK Sample

1. Download the sample

   Download sample-app-react-sdk-<version>-<os>-<arch>.zip from the latest release.

2. Unzip and navigate to the sample app directory

   unzip sample-app-react-sdk-<version>-<os>-<arch>.zip
   cd sample-app-react-sdk-<version>-<os>-<arch>/
   

3. Start the sample

   ./start.sh
   

   Open your browser and navigate to https://localhost:3000 to access the sample app.

   📖 Refer to the README.md inside the extracted sample app for detailed configuration and troubleshooting.

Self Register and Login (React Vanilla Sample)

The React Vanilla sample supports user self-registration and login:

1. Open https://localhost:3000 and click "Sign up" to register a new user.

2. After registration, use the same credentials to "Sign In".

   <p align="left"> <img src="resources/images/sample-app-login.png" alt="Login to Sample App" width="400"> </p>

3. Upon successful login, you'll see the home page with your access token.

Obtain System API Token

To access the system APIs of Thunder, you need a token with system permissions. Follow the steps below to obtain a system API token.

1. Run the following command, replacing <application_id> with the sample app ID generated during "Setup the product."

curl -k -X POST 'https://localhost:8090/flow/execute' \
  -d '{"applicationId":"<application_id>","flowType":"AUTHENTICATION"}'

2. Extract the executionId value from the response.

{"executionId":"<execution_id>","flowStatus":"INCOMPLETE", ...}

3. Run the following command, replacing <execution_id> with the executionId value you extracted above.

curl -k -X POST 'https://localhost:8090/flow/execute' \
  -d '{"executionId":"<execution_id>", "inputs":{"username":"admin","password":"admin", "requested_permissions":"system"},"action": "action_001"}'

4. Obtain the system API token by extracting the assertion value from the response.

{"executionId":"<execution_id>","flowStatus":"COMPLETE","data":{},"assertion":"<assertion>"}

Try Out Client Credentials Flow

The Client Credentials flow is used to obtain an access token for machine-to-machine communication. This flow does not require user interaction and is typically used for server-to-server communication.

To try out the Client Credentials flow, follow these steps:

1. Create a Client Application

   Application creation is secured functionality, so you first need to obtain a system API token as mentioned in the "Obtain System API Token" section above.

   Run the following command, replacing <assertion> with the assertion value obtained from the previous step.

   curl -kL -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' https://localhost:8090/applications \
   -H 'Authorization: Bearer <assertion>' \
   -d '{
