Voiceflow Runtime Client

The Voiceflow Runtime Client is an SDK for running Voiceflow apps in JavaScript.

First, you build a fully-functioning conversational app on Voiceflow. Then, you integrate that app into a JavaScript project using the SDK. This allows you to quickly add any kind of voice interface, such as a chatbot, to your project, without the hassle of implementing the conversational flow using code.

The Runtime Client can be used with jQuery, React, and any other JavaScript library or framework.

Getting Started

Minimal Working Integration

The minimum code to start using the SDK is shown below:

const { default: RuntimeClientFactory } = require('@voiceflow/runtime-client-js');
// alternatively for ESM/ES6
// import RuntimeClientFactory from '@voiceflow/runtime-client-js'

// Construct a chatbot instance
const factory = new RuntimeClientFactory({
  versionID: 'your-version-id-here', 	// ADD YOUR VERSION ID HERE
  apiKey: 'your-api-key-here', // ADD YOUR API KEY HERE
});
const client = factory.createClient();

// When the chatbot responds with text, output it
client.onSpeak((trace) => console.log(trace.payload.message));

// (Optional) explicitly begin a conversation session
client.start();

// Call this function from any input source
const interact = (input) => client.sendText(input);

// e.g. interact('can I have fries with that');

Pass in user input with the client.sendText(input) function, and any of your client.on... handlers will trigger during the response.
