nlbridge
is a Node.js library that provides utilities, middleware, and a development server for building APIs
powered by large language models.
This package @nlbridge/express
provides an Express.js middleware for nlbridge
. It can be used to build custom APIs
that connect to large language models, and expose them as HTTP endpoints. It's designed to easily integrate with
nlux
(the conversational UI React and JS library), but it can also be used independently with any
other client.
To use the nlbridge
middleware in your own Express.js server, install the @nlbridge/express
package:
npm install @nlbridge/express
Then, use the middleware in your Express.js server:
import {middleware} from '@nlbridge/express';
const app = express();
app.use(middleware(
// The AI backend to use (e.g. 'openai'). Only OpenAI is supported at the moment.
'openai',
// Configuration object. Ref below for details.
actions,
));
Config is an object with the following type:
type MiddlewareConfig = {
apiKey?: string;
chatModel?: string;
chatMode?: 'stream' | 'block';
};
nlbridge
is designed to work seamlessly with nlux
, the conversational UI library for any large language model.
