NodeJS Backend Server

Configure Project

First install the npm library in your project.

npm i @dapi-co/dapi-node

Import Dapi's library in your code.

import DapiApp from '@dapi-co/dapi-node'

const DapiApp = require('@dapi-co/dapi-node')

Create a Dapi app with your App Secret

import DapiApp from '@dapi-co/dapi-node'

const dapi = new DapiApp({
  appSecret: 'YOUR_APP_SECRET',
})

const DapiApp = require('@dapi-co/dapi-node')

const dapi = new DapiApp.default({
  appSecret: 'YOUR_APP_SECRET',
})

Configure SDK Server

Follow the steps in Configure Project first in order to obtain and import the library.
Now inside your endpoint, our code will basically use the request and result variables. We will assume you named them req and res

try {

  const dapiResponse = dapi.handleSDKDapiRequests(req.body, req.headers)
  res.send(dapiResponse)

} catch (error) {

  //Handle Network Errors
  console.dir(error)

}

That's it. You can now test Dapi in action

Complete SDK Server Example

Here is a complete example of how it will look like in a node express app. You can see an example for both ways of importing JavaScript modules.

var express = require('express')
const DapiApp = require('@dapi-co/dapi-node')
var cors = require('cors')

const app = express()
const port = 8060 // default port to listen
app.use(cors())
app.use(express.json())

const dapi = new DapiApp.default({
  appSecret: 'YOUR_APP_SECRET',
})

// define a route handler for the sdk
app.post('/dapi', async (req, res) => {

  try {
    
    const dapiResponse = await dapi.handleSDKDapiRequests(req.body, req.headers)
    res.send(dapiResponse)

  } catch (error) {

    //Handle Network Errors
    console.dir(error)
  }
})

// start the Express server
app.listen(port, () => {
  console.log(`server started at http://localhost:${port}`)
})

import * as express from 'express'
import DapiApp from '@dapi-co/dapi-node'

const app = express()
const port = 8060 // default port to listen
app.use(express.json())

const dapi = new DapiApp({
  appSecret: 'YOUR_APP_SECRET',
})

// define a route handler for the sdk
app.post('/dapi', async (req, res) => {

  try {

    const dapiResponse = await dapi.handleSDKDapiRequests(req.body, req.headers)
    res.send(dapiResponse)

  } catch (error) {

    //Handle Network Errors
    console.dir(error)
  }
})

// start the Express server
app.listen(port, () => {
  console.log(`server started at http://localhost:${port}`)
})
