Overview of Shopify App Development with NodeJS

The main use of Node Js is the creation of scalable mobile and online application space. It is a free and open-source runtime framework for JavaScript that provides a V8 engine for code execution from the web browser. It provides an efficient environment for programs that do not require a browser. Node Js compatibility can be achieved more easily with a better compiler and user-friendly interface compared to older code formats.

There is a complete deadlock when using NodeJS for Shopify app development. The process comes to a halt as NodeJS cannot execute any I/O functions directly. Thus, if the I/O operates in sync with the NodeJS library then it presents different options.

Because there will be no blockage in the way of building a scalable system. Moreover, the best option is NodeJS development for better speed. And design Shopify applications easily in less time.

Overview of Shopify and Its Ecosystem

If you are an online retailer, you must be aware of Shopify and how it facilitates company operations for businesses. Since every company is different, its needs for success are also different. With extended web apps, NodeJS app development for Shopify is coming to enhance your online visibility. It also makes it easier for businesses to modify their applications. Additional ways to incorporate Shopify into your application are as follows:

Make the most of your existing program by adding the latest POS features.
To enable the app to read and write product information, connect the admin to the Shopify API.
To attract users, you can improve how information is presented.

Shopify App Development with Node Js

Install Node Js

Installing the latest Node Js version on your system is the first step to creating a customized Shopify app. Installation of Node Js is the most important thing while creating a new improved and customized Shopify app. If you don’t already have Node Js installed, you can get the current updated version from their official website.

If you already have the Node Js version but not the required version, you can update the Node Js framework before proceeding.

Create A Project Folder

The next most important step is to prepare the system for the development of Shopify different. So, here is the list of essential node packages that you should have on your system.

MySQL
Crypto
Cookie
Body-parser
Shopify node API
Dotenv
Nonce

To install the above-listed elements, We have to run the next command.

Install Ngrok to create a tunnel from the online internet to your local machine

Let's start with the definition of Ngrok.

A cross-platform tool called Ngrok enables designers to easily make a local development server available online. This software removes the need for a public IP address or domain name on the local system by making your locally hosted web server hosted on a subdomain of ngrok.com.

Ngrok tunnel

The second step is to get Ngrok from its official website. It has a config file that will support the installation and setup of another app. And afterward, run the ngrok.exe file and enter the command Ngrok.

You need to allow API calls to the app you want to build. This is necessary because whenever the app requires SSL to make calls, you will need to use Ngrok for that. You can use Ngrok to highlight SSL URLs directly from the localhost.

Hash-based message authentication code (HMAC ) generation and validation

Shopify apps confirm that a request began on the Shopify platform by using HMAC verification. Using a secret key, Shopify creates an HMAC of the request body, which it submits along with the request.

Index.js cod

const crypto = require(‘crypto’);

const nonce = require(‘nonce’)();

const request = require(‘request-promise’);

const querystring = require(‘querystring’);

const cookie = require(‘cookie’);

const express = require(‘express’);

const dotenv = require(‘dotenv’);

dotenv.config();

const {SHOPIFY_API_KEY,SHOPIFY_API_SECRET} = process.env;

const app = express();

const apiKey = SHOPIFY_API_KEY;

const apisecret = SHOPIFY_API_SECRET;

const scopes = “read_themes,write_themes”;

const forwardingaddress =”URL“;

app.get(‘/shopify’, (req, res) => {

// Shop Name

const shop = req.query.shop;

if (shop) {

const state = nonce();

// redirect

const redirectURL = forwardingaddress + ‘/shopify/callback’;

// Install

const shopifyURL = ‘https://’ + shop +

‘/admin/oauth/authorize?client_id=’ + apiKey +

‘&scope=’ + scopes+

‘&state=’ + state +

‘&redirect_uri=’ + redirectURL;

res.cookie(‘state’, state);

res.redirect(shopifyURL);

} else {

return res.status(400).send(‘Missing “Shop Name” parameter!! please add’);

}

});

app.get(‘/shopify/callback’, (req, res)=>{

const{shop, hmac , code , shopState} = req.query;

const stateCookie = cookie.parse (req.headers.cookie).shopState;

if (shopState !== stateCookie)

{

return res.status(400).send(“request origin cannot be found”)

}

if(shop && hmac && code)

{

const Map = Object.assign({}, req.query);

delete Map[‘hmac’];

const message = querystring.stringify(Map);

const generatehmac = crypto

.createHmac(‘sha256’, apisecret)

.update(message)

.digest(‘hex’)

console.log(generatehmac)

if (generatehmac !== hmac ){

return res.status(403).send(“validation failed”)

}

const accessTokenRequestUrl = ‘https://’ + shop + ‘/admin/oauth/access_token’;

const accessTokenPayload = {

client_id: apiKey,

client_secret: apisecret,

code,

};

request.post(accessTokenRequestUrl, {json: accessTokenPayload})

.then((accessTokenResponse) => {

const accessToken = accessTokenResponse.access_token;

const apiRequestURL = ‘https://’ + shop + ‘/admin/shop.json’;

const apiRequestHeaders =

{

‘X-Shopify-Access-Token’: accessToken

};

request.get(apiRequestURL, {headers: apiRequestHeaders})

.then((apiResponse) =>{

res.end(apiResponse);

})

.catch((error) => {

res.status(error.statusCode).send(error.error.error_description);

});

})

.catch((error) => {

res.status(error.statusCode).send(error.error.error_description);

});

}

else{

return res.status(400).send(“required parameter missing”) } });

app.listen(6379, () => console.log(‘App is running on port 6379’));

Now login to your Shopify Developer admin and start creating an app

After logging into your Shopify Developer admin, click on Create App and a popup will come up where you will enter the app name and the Ngrok URL (https://) that was obtained in the previous step.

Buy a secret key to authenticate an app

After the app is built, we will get the Shopify API key, Shopify secret key and Shopify access token from the Shopify developer page. You can also update it and save it to another location. In index.js, you can change the Shopify key and secret key.

Place Ngrok URL with (https://) in-app URL and maintain the same with the /Shopify/callback in whitelisted redirection URL(s).

Use the same credentials in the .env file to set the common constants where we need to update the Shopify API key and secret key which we will use in the code of the index.js file.

As per the above screenshot SHOPIFY_API_KEY and SHOPIFY_API_SECRET will be the API keys.

Use Ngrok URL with your shop name

After that, use the Ngrok URL with your node shop name as shown below;

It was finally installed in the App Store!

Bottom-line

The steps given above will help you develop a scalable and profitable app on Shopify using Node Js. It will meet all your criteria and also provide a great UX and UI to your customers. You can use this information to create the best Shopify application that will guide you in showcasing your business to your customers effortlessly.
