Getting Started

You have to create a Luis Application following Microsoft Documentation.

Once your application created you will use the Luis Client as http.js

const superagent = require('superagent');
require('superagent-proxy')(superagent)
const agent = superagent.agent();

// set proxy on each request
agent.use((req) => {
    if (process.env.HTTP_PROXY) {
        req.proxy(process.env.HTTP_PROXY);
    }
    return req;
});


module.exports = agent ;

luis.js

const LUISClient = require('luis-client').default;
const agent = require('./http');

const client = new LUISClient({
    appId: '<your application id>',
    appKey: '<your application key>',
    authoringKey: '<your authoring key here>',
    verbose: '<true / false>',
    region: '<your region here>',
    version: '<the luis version>',
    versionId: '<your luis app version>'
}, agent);

    "type": "object",
    "properties": {
        "text": {
            "type": "string"
        },
