Node.js RESTful API Proxy

The Inworld Node.js RESTful API is available here.

Description​

This project is a Node.js based RESTful service of Inworld AI streaming SDK. The service allows for creation, management and closure of multiple AI character sessions. The service can handle multiple users as well as multiple servers automatically depending on how the Character session is created. The service can access characters from many scenes contained within a single Inworld Workspace.

npm start

Generating Documentation​

If you contribute to this OpenSource project use this to update the code documentation.

npm run docs

Documentation​

  • Route Documentation - Can be found on Postman here
  • Code Documentation - The TSDocs code documentation can be found in this project at docs/index.html

Use the route documentation to open a session and generate a Session ID. Use that Session ID to send a chat message to the character and then get the events to retrieve the response messages. It is important to close the session after the chat has been completed to prevent conflicts and duplicate sessions.

Basic Route Flow:1. Session Open - Opens a new chat session with a character 2. Session Send Chat Message - Sends a chat message to the character 3. Service Get All Events - Retrieves the response messages from the character 4. Session Close - End the chat session with the character

Included in this project is a Postman Collection file you can import and test the routes with. The file is located in this project at postman/Inworld RESTful API Routes.postman_collection.json. To change the default server host from http://localhost:3000, select the Inworld RESTful API Routes collection and click on the Variables tab. Update the {{HOST}} variable to reflect a new base url.

Note: The Postman Agent desktop application is needed to call the routes via `http://localhost:3000`.

PM2 Server Installation & Setup (Optional)​

PM2 can be used to run on a dedicated server in the background as a stable daemon that will restart on crashing and reboot. More documentation on PM2 can be found here

PM2 Terminal Installation Commands​

sudo npm install -g pm2
pm2 startup
pm2 start pm2.sh --name inworld
pm2 save
