Example 1 — first question

This example will guide you through how to send your first question to the API. Create a new file medisearch_client.js.

Paste the following code into medisearch_client.js. This is just to generate an id for your conversation with MediSearch.

function generateID() {
  var id = '';
  var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';

  for (var i = 0; i < 32; i++) {
    id += characters.charAt(Math.floor(Math.random() * characters.length));
  }

  return id;
}

conversation_id = generateID();

Use the above code to generate a new id for each new conversation, but not for each new question. Now create a userConversation object and paste it into medisearch_client.js as follows.

const userConversation = {
	event: "user_message",
  conversation: ["Is cancer transmissible?"],
  key: "your-api-key",
	id: conversation_id,
	settings: {
		language: "English"
	}
}

In the above, don’t forget to

• replace 'your-api-key' with your api key (which you obtain by emailing [email protected]).
• replace 'Is cancer transmissible?' with your question

The last step is to paste the following code into medisearch_client.js. This piece of code sends the request to our server and receives a response.

const WebSocket = require('ws');

const ws = new WebSocket('wss://public.backend.medisearch.io:443/ws/medichat/api');

// Prepare for receiving the request
ws.on('message', function incoming(data) {
  const strData = data.toString('utf8');
  const jsonData = JSON.parse(strData);
	
	if (jsonData.event === "articles") {
      console.log("Got articles");
  } else if (jsonData.event === "llm_response") {
      console.log("Got llm response");
  } else if (jsonData.event === "error") {
      console.log("Got error");
  }
  console.log(jsonData);
});

// WebSocket is open, time to send a request.
ws.on('open', function open() {
  ws.send(JSON.stringify(userConversation));
});

Finally, to run this code, open your terminal and run node medisearch_client.js.
