Framework Introduction

To simplify the integration to RELE.AI, RELE.AI (opens new window) provides a gRPC based framework to connect your internal services.

Installation

Assuming you've already installed Node.js (opens new window), create a directory to hold your application, and make that your working directory.

mkdir myapp
cd myapp

Use the npm init command to create a package.json file for your application.

npm init

This command prompts you for a number of things, such as the name and version of your application. For now, you can simply hit RETURN to accept the defaults.

Now install the rb-node-sdk in the myapp directory and save it in the dependencies list. For example:

npm install @releai/rb-node-sdk --save

Hello World

The following example starts a server on port 3000 for connections. The app responses with a protobuf.Struct (opens new window) message to RELE.AI.

// import the rb-server to the code
const { RBS } = require("@releai/rb-node-sdk")
const router = new RBS.Router()

// initiate the application
const rbs = new RBS({
    appId: process.env.APP_ID,
    appHash: process.env.APP_HASH
})

// register the hello_world operation
router.use("hello_world", (req, res) => {
    res.send(200, { message: "Hello World!" })
})

// use exported router
rbs.use(router)

// initiate the listener
rbs.listen(3000)

NOTE

To get your APP_ID and APP_HASH please use rb app:tokens command.
