Next, you’ll need to expose the port the server is running on, which in our case is port 3000. In this step, you are going to use Ngrok to expose your localhost server to the internet.įirst, get the Express server up and running. In the next step, you will expose the server to the internet with Ngrok. Next, start up the server by running node index.js.įinally, opening should return the same data found in the movies.json file, as expected.Ĭongratulations!!! You have managed to build and locally serve a Node.js REST API built with Express! Next, you will write a simple “Hello World” app.Ĭreate an index.js file and add the code below to it.Ĭonst port = 3000 const fs = require( 'fs')Īpp. In this step, you will write up an Express server with Node.js and run it locally.Īfter the setup you should have one directory node_modules and two files package.json & package-lock.json. Step 1 - Build and Run an Express Server with Node.js

Prerequisitesīefore you begin this guide you’ll need the following: A RESTful web service usually defines a URI which provides resource representation such as JSON and set of HTTP Methods.

These web services use HTTP methods to implement the concept of REST architecture. Web services based on REST Architecture are known as RESTful web services.

In this guide, you will build a Node.js REST API with the Express Framework, expose it to the internet with Ngrok and make test requests to it on Postman.
