As Head of Product Strategy at BigCommerce, I often get to work with developers that are looking to quickly extend what our platform can do and enable a UI for merchants to interface with the new functionality they create. Something I’ve been wanting to offer those developers is a way to fast-track their concepts into a functional app on our platform — a boilerplate app using a popular BE and FE framework that is easily accessible.

While waiting for that problem to be magically solved, I had been prototyping a concept on my own time using some of our new Widget APIs, and realized out of necessity I had already created the foundation for a simple Laravel & React based app in the process.

This tutorial will walk you through the steps to get a functional application using Laravel on the backend and React on the front end up and running. Its purpose is to fast-track your understanding of what it takes to quickly build a BigCommerce application using approachable, modern frameworks.

In the end, you will have a basic two-screen application with routing. You can run it locally, or install it on your BigCommerce store. Run API requests, display the results, and make actions.

And yes, the link to GitHub with the final code is at the bottom.

Prerequisites

Before jumping in, you’ll want to make sure you have installed the following dependencies on your dev machine:

To ease PHP development and enable the app you develop to be easily shared, you’ll want to use either Valet or Homestead, depending on your OS:

We’ll be using Valet for some of the steps below, but the functionality to host and share sites is similar across both Valet and Homestead. What’s more important in this tutorial is how to configure Laravel to use React and connect with BigCommerce.

Let’s get started!

Step 1: Getting Laravel and React Running Together

This is where we will create a baseline for future development: a simple application that loads at a specific URL in your browser and loads a React component instead of the default Laravel screen.

Create a new Laravel codebase

You can either use the Laravel command that creates the initial boilerplate for an app in the ~/Sites directory or use Composer:

composer global require laravel/installer
laravel new laravel-react-bigcommerce-app

or

composer create-project laravel/laravel 
laravel-react-bigcommerce-app

You should see the command run its course, like this:

Visit the app address to make sure it’s live locally

After the command above completes, we will need to set up the directory so Valet can serve the app securely.

cd laravel-react-bigcommerce-app
valet link
valet secure

You should now be able to visit the following URL in your browser and see the default Laravel welcome screen:

https://laravel-react-bigcommerce-app.test

Set up React as the JS framework using Breeze and Inertia

Larvel Breeze provides a minimal and simple starting point for building a Laravel application, with authentication features. It’s powered by Blade and Tailwind but can be configured as an SPA using Inertia. In this example, we will power our front end with react.

First, let’s install Breeze:

composer require laravel/breeze --dev

Then we install the react scaffolding:

php artisan breeze:install react

Note: this last command executed npm install so no need to run this command.

Lastly, get the application running:

npm run dev

A Local URL should now be available in your console to visit your react application: http://127.0.0.1:5173/

Step 2: Set up a Basic App

Now that you are set up for React development with a Laravel back-end, you are ready to implement routes, pages, and navigation within the app.

Routes

Open up /routes/web.php and edit the file to reflect the following routes:

Route::get('/', function () {
return Inertia::render('Home');
});

Route::get('/list', function () {
return Inertia::render('List');
});

Note: Breeze installs scaffolding for authentication routes to be used with your React app. You’ll have to modify them if you intend to use these routes in the future, or replace them with above routes

Pages

Create /resources/js/Pages/Home.jsx

import Navigation from '@/Components/Navigation';

import { Head } from '@inertiajs/react';
import React from 'react';

export default class Home extends React.Component {
render() {
return (
<>
<Head title="Home" />
<Navigation />

<div className="container mx-auto p-5">
<div className="grid grid-cols-4 gap-4">
<div className="content col-span-3 grid-col-3 rounded bg-gray-100 shadow-lg p-4">
<h2 className="text-xl font-bold mb-6">This is the Home Page.</h2>
</div>
<div className="sidebar rounded bg-gray-100 shadow-lg p-4">
<h2 className="text-xl font-bold mb-6">This is a Side Bar.</h2>
</div>
</div>
</div>
</>
);
}
}

Create /resources/js/Pages/List.jsx

import Navigation from '@/Components/Navigation';

import { Head } from '@inertiajs/react';
import React from 'react';

export default class List extends React.Component {
render() {
return (
<>
<Head title="Order List" />
<Navigation />

<div className="container mx-auto p-5">
<div className="content col-span-3 grid-col-3 rounded bg-gray-100 shadow-lg p-4">
<h2 className="text-xl font-bold mb-6">List of Orders</h2>
</div>
</div>
</>
);
}
}

Navigation Component

When creating the two pages above you may have noticed we imported a navigation component. Let’s create it!

Create /resources/js/Components/Navigation.jsx

import { Link } from '@inertiajs/react';

export default function Navigation() {
return (
<nav className="flex items-center justify-between flex-wrap bg-gray-500 p-6">
<div className="flex items-center flex-shrink-0 text-white mr-6">
<ul className="flex">
<li className="mr-6">
<Link className="text-white hover:text-blue-800" href="/">Home</Link>
</li>
<li className="mr-6">
<Link className="text-white hover:text-blue-800" href="/list">List</Link>
</li>
</ul>
</div>
</nav>
);
};

Summary

You should now have a working application with React, Routes, Pages, and Components. Navigate to https://laravel-react-bigcommerce-app.test and you’ll now see a functional layout for an app, including navigation, appear!

Step 3: Connect the App with BigCommerce

Alright, it’s time to start connecting the app to real data inside a BigCommerce store.

Create app in the BigCommerce dev tools area

Head to devtools.bigcommerce.com and log in with your BigCommerce store account. Create an app and go to the ‘Technical’ step in the modal.

To start, you want at least the auth and load callback URLs to be set, since those are what BigCommerce will use to initiate the install process and enable the app to load within the BigCommerce control panel.

After setting the callback URLs, you need to select which scopes your app will need. Keep track of this because your app will need to check the proper scopes have been granted when installed. If you were making a real app, you would only select what the app actually needs here, as BigCommerce will work to ensure you don’t have too many permissions.

Save your app’s client ID and secret

The client ID and Secret are used to verify that your app requests are valid. Save these into environment variables within your app. In the sample Laravel app, we’re saving these in the .env file along with the scopes so each piece of app info is able to be set in one place.

Update your .env file (in the root app directory) to have the APP_URL set as https://laravel-react-bigcommerce-app.test and add new env variables at the bottom of the file for your BigCommerce App IDs and test API credentials for local dev.

# Existing env variable. Make sure it matches the base URL of your app
APP_URL=https://laravel-react-bigcommerce-app.test

[ ... other existing variables ... ]

# New env variables for BigCommerce app and a test API credentials for local dev
# The Client ID and Secret can be found at https://devtools.bigcommerce.com/my/apps by selecting 'View Client ID'
BC_APP_CLIENT_ID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
BC_APP_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# These local credentials can be created by creating an API Account within your BigCommerce store (Advanced Settings > Store Level API Account)
BC_LOCAL_CLIENT_ID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
BC_LOCAL_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
BC_LOCAL_ACCESS_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
BC_LOCAL_STORE_HASH=stores/xxxxxxxxxxx

Set up the install, load and BigCommerce API proxy routes

When the app is installed, it will look at the callbacks that are defined in the dev tools area.

Add the web routes below & use App\Http\Controllers\MainController; to web.php found in laravel-react-sample-app/routes/web.php, so Laravel knows to route to the specific controller methods for each callback. We are implementing install and load here, to get the baseline experience working, however, there are stubbed routes for future functionality like uninstall and remove-user.

use App\Http\Controllers\MainController; //add this to the top of the page

Route::get('/{url?}', function () {
return view('app');
})->where('', 'list');

Route::group(['prefix' => 'auth'], function () {
Route::get('install', 'MainController@install');

Route::get('load', 'MainController@load');

Route::get('uninstall', function () {
echo 'uninstall';
return app()->version();
});

Route::get('remove-user', function () {
echo 'remove-user';
return app()->version();
});
});

Route::any('/bc-api/{endpoint}', 'MainController@proxyBigCommerceAPIRequest')
->where('endpoint', 'v2\/.*|v3\/.*');

Create a controller to handle app install and load requests, proxy BigCommerce API

You can see above that there are references to ‘MainController’. That is where we’ll put the logic that handles the OAuth handshake and stores the credentials generated for the store. Remember that this uses session-based storage, so when the browser session expires, the app will stop working.

The last route is a proxy through to the BigCommerce v2 and v3 APIs. We’ll use that to enable a bc-api endpoint we can hit on the front end, which helps us bypass CORS issues.

Create /app/Http/Controllers/MainController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;
use Illuminate\Http\Request;
use Illuminate\Http\RedirectResponse;
use Illuminate\Support\Facades\Redirect;

use GuzzleHttp\Exception\RequestException;

use GuzzleHttp\Client;

class MainController extends BaseController
{
protected $baseURL;

public function __construct()
{
$this->baseURL = env('APP_URL');
}

public function getAppClientId()
{
if (env('APP_ENV') === 'local') {
return env('BC_LOCAL_CLIENT_ID');
} else {
return env('BC_APP_CLIENT_ID');
}
}

public function getAppSecret(Request $request)
{
if (env('APP_ENV') === 'local') {
return env('BC_LOCAL_SECRET');
} else {
return env('BC_APP_SECRET');
}
}

public function getAccessToken(Request $request)
{
if (env('APP_ENV') === 'local') {
return env('BC_LOCAL_ACCESS_TOKEN');
} else {
return $request->session()->get('access_token');
}
}

public function getStoreHash(Request $request)
{
if (env('APP_ENV') === 'local') {
return env('BC_LOCAL_STORE_HASH');
} else {
return $request->session()->get('store_hash');
}
}

public function install(Request $request): RedirectResponse
{
// Make sure all required query params have been passed
if (!$request->has('code') || !$request->has('scope') || !$request->has('context')) {
return redirect()->action([MainController::class, 'error'], ['error_message' => 'Not enough information was passed to install this app.']);
}

try {
$client = new Client();
$result = $client->request('POST', 'https://login.bigcommerce.com/oauth2/token', [
'json' => [
'client_id' => $this->getAppClientId(),
'client_secret' => $this->getAppSecret($request),
'redirect_uri' => $this->baseURL . '/auth/install',
'grant_type' => 'authorization_code',
'code' => $request->input('code'),
'scope' => $request->input('scope'),
'context' => $request->input('context'),
]
]);

$statusCode = $result->getStatusCode();
$data = json_decode($result->getBody(), true);

if ($statusCode == 200) {
$request->session()->put('store_hash', $data['context']);
$request->session()->put('access_token', $data['access_token']);
$request->session()->put('user_id', $data['user']['id']);
$request->session()->put('user_email', $data['user']['email']);

// If the merchant installed the app via an external link, redirect back to the

if ($request->has('external_install')) {
return Redirect::to('https://login.bigcommerce.com/app/' . $this->getAppClientId() . '/install/succeeded');
}
}

return Redirect::to('/');
} catch (RequestException $e) {
$statusCode = $e->getResponse()->getStatusCode();
$errorMessage = "An error occurred.";

if ($e->hasResponse()) {
if ($statusCode != 500) {
$errorMessage = $e->getResponse();
}
}

// If the merchant installed the app via an external link, redirect back to the
// BC installation failure page for this app
if ($request->has('external_install')) {
return Redirect::to('https://login.bigcommerce.com/app/' . $this->getAppClientId() . '/install/failed');
} else {
return redirect()->action([MainController::class, 'error'], ['error_message' => $errorMessage]);
}
}
}

public function load(Request $request): RedirectResponse
{
$signedPayload = $request->input('signed_payload');
if (!empty($signedPayload)) {
$verifiedSignedRequestData = $this->verifySignedRequest($signedPayload, $request);
if ($verifiedSignedRequestData !== null) {
$request->session()->put('user_id', $verifiedSignedRequestData['user']['id']);
$request->session()->put('user_email', $verifiedSignedRequestData['user']['email']);
$request->session()->put('owner_id', $verifiedSignedRequestData['owner']['id']);
$request->session()->put('owner_email', $verifiedSignedRequestData['owner']['email']);
$request->session()->put('store_hash', $verifiedSignedRequestData['context']);

} else {
return redirect()->action([MainController::class, 'error'], ['error_message' => 'The signed request from BigCommerce could not be validated.']);
}
} else {
return redirect()->action([MainController::class, 'error'], ['error_message' => 'The signed request from BigCommerce was empty.']);
}

$request->session()->regenerate();

return Redirect::to('/');
}

public function error(Request $request)
{
$errorMessage = "Internal Application Error";

if ($request->session()->has('error_message')) {
$errorMessage = $request->session()->get('error_message');
}

echo '<h4>An issue has occurred:</h4> <p>' . $errorMessage . '</p> <a href="' . $this->baseURL . '">Go back to home</a>';
}

private function verifySignedRequest($signedRequest, $appRequest)
{
list($encodedData, $encodedSignature) = explode('.', $signedRequest, 2);

// decode the data
$signature = base64_decode($encodedSignature);
$jsonStr = base64_decode($encodedData);
$data = json_decode($jsonStr, true);

// confirm the signature
$expectedSignature = hash_hmac('sha256', $jsonStr, $this->getAppSecret($appRequest), $raw = false);
if (!hash_equals($expectedSignature, $signature)) {
error_log('Bad signed request from BigCommerce!');
return null;
}
return $data;
}

public function makeBigCommerceAPIRequest(Request $request, $endpoint)
{
$requestConfig = [
'headers' => [
'X-Auth-Client' => $this->getAppClientId(),
'X-Auth-Token' => $this->getAccessToken($request),
'Content-Type' => 'application/json',
]
];

if ($request->method() === 'PUT') {
$requestConfig['body'] = $request->getContent();
}

$client = new Client();
$result = $client->request($request->method(), 'https://api.bigcommerce.com/' . $this->getStoreHash($request) .'/'. $endpoint, $requestConfig);

return $result;
}

public function proxyBigCommerceAPIRequest(Request $request, $endpoint)
{
if (strrpos($endpoint, 'v2') !== false) {
// For v2 endpoints, add a .json to the end of each endpoint, to normalize against the v3 API standards
$endpoint .= '.json';
}

$result = $this->makeBigCommerceAPIRequest($request, $endpoint);

return response($result->getBody(), $result->getStatusCode())->header('Content-Type', 'application/json');
}
}

Note: By default, your app is set to use your hardcoded API credentials in the .env file. When you install the app within BigCommerce, you want your app to use the credentials passed back during the OAuth token exchange. To do this, make sure your APP_ENV config value in your .env file is set to production, like so:

APP_ENV=production

Now, if you head to your BigCommerce store admin, to the Apps -> My Apps -> My Draft Apps section, you can install your app and see it successfully load inside the control panel.

Step 4. Create a front-end experience that surfaces data in BigCommerce

All the pieces are in place to create front-end components that actually do something, so I created a simple set of React components and screens that:

  • Load a brief catalog summary and store information
  • List the last 10 orders and enable the user to cancel them

To enable the front-end components to hit the API using the back-end BigCommerce API Proxy endpoints in MainController.php, add the following files to a new /resources/js/Services/ directory:

Create /resources/js/Services/ApiServices.js

export const ApiService = {
getOrders(params) {
params = Object.assign({
page: 1,
limit: 10,
}, params);

return axios({
method: 'get',
url: '/bc-api/v2/orders',
params,
});
},

updateOrder(orderId, data) {
return axios({
method: 'put',
url: `/bc-api/v2/orders/${orderId}`,
data,
});
},

deleteOrder(orderId) {
return axios({
method: 'delete',
url: `/bc-api/v2/orders/${orderId}`,
});
},

getResourceCollection(resource, params) {
params = Object.assign({
page: 1,
limit: 10,
}, params);

return axios({
method: 'get',
url: `/bc-api/${resource}`,
params,
});
},

getResourceEntry(resource, params) {
return axios({
method: 'get',
url: `/bc-api/${resource}`,
params,
});
},

updateResourceEntry(resource, data) {
return axios({
method: 'put',
url: `/bc-api/${resource}`,
data,
});
},

deleteResourceEntry(resource, data) {
return axios({
method: 'delete',
url: `/bc-api/${resource}`,
});
},
};

Create /resources/js/Services/index.js

import { ApiServices } from './ApiServices';

export {
ApiService,
};

Let’s create two new components:

Create /resources/js/components/Table.jsx that will contain a basic Table component, like below:

import React from 'react';

export default class Table extends React.Component {
constructor(props) {
super(props);
}

getTableRow(data, index) {
return (
<tr key={index}>
{this.props.tableHeaders.map(function (header, index) {
let value = data;
if (header.index) {
value = data[header.index];
}

if (header.callback) {
value = header.callback(value);
}

return <td className="px-4 py-4 whitespace-nowrap" key={index}>{value}</td>;
})}
</tr>
);
}

render() {
return (
<table className="min-w-full divide-y divide-gray-200">
<thead className="bg-gray-200">
<tr>{this.props.tableHeaders.map(function (header, index) {
return <th className="py-3.5 px-4 text-left" key={index}>{header.label}</th>;
})}</tr>
</thead>
<tbody className="bg-white divide-y divide-gray-200">
{this.props.tableData.map(this.getTableRow.bind(this))}
</tbody>
</table>
);
}
}

Create /resources/js/components/Spinner.jsx that will contain a basic Spinner component

export default function Spinner() {
return (
<div className="text-center">
<div className="m-5" role="status">
<svg width="24" height="24" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path d="M12,1A11,11,0,1,0,23,12,11,11,0,0,0,12,1Zm0,19a8,8,0,1,1,8-8A8,8,0,0,1,12,20Z" opacity=".25" /><circle cx="12" cy="2.5" r="1.5"><animateTransform attributeName="transform" type="rotate" dur="0.75s" values="0 12 12;360 12 12" repeatCount="indefinite" /></circle></svg>
<span className="sr-only">Loading...</span>
</div>
</div>
);
}

Now, with the API service and components in place, the screens can be updated to produce something functional. To bring it all together, change the following files:

/resources/js/Pages/Home.jsx

import Navigation from '@/Components/Navigation';
import Spinner from '@/Components/Spinner';
import { ApiService } from '@/Services';

import { Head } from '@inertiajs/react';
import React from 'react';

export default class Home extends React.Component {
constructor(props) {
super(props);

this.state = {
isCatalogSummaryLoading: true,
isStoreInfoLoading: true,
catalogSummary: {},
storeInfo: {},
};
}

componentDidMount() {
ApiService.getResourceEntry('v2/store').then(this.handleStoreInfoResponse.bind(this));
ApiService.getResourceEntry('v3/catalog/summary').then(this.handleCatalogSummaryResponse.bind(this));
}

handleStoreInfoResponse(response) {
this.setState({
isStoreInfoLoading: false,
storeInfo: response.data,
});
}

handleCatalogSummaryResponse(response) {
this.setState({
isCatalogSummaryLoading: false,
catalogSummary: response.data.data,
});
}

render() {
const fieldsInSummary = [
{
label: "Variant Count",
index: "variant_count",
format: "number",
},
{
label: "Inventory Count",
index: "variant_count",
format: "number",
},
{

},
];
return (

{
this.state.isStoreInfoLoading

:

?
new Intl.NumberFormat(undefined, { style: 'currency', currency: this.state.storeInfo.currency }).format(this.state.catalogSummary[summaryItem.index])
:
this.state.catalogSummary[summaryItem.index]

}
</span>
}
</div>;
}.bind(this))}
</div>
</div>
<div className="sidebar rounded bg-gray-100 shadow-lg p-4">
<h2 className="text-xl font-bold mb-6">This is a Side Bar.</h2>
{

);
}
}

}

What’s next?

If you got this far, congrats! You have a great base to work on as you experiment with all the BigCommerce APIs.

To launch a real app, aside from hosting it on a server other than your dev box. You’ll still need to add some persistent storage for API credentials, storing the store and user info received from the OAuth token request during app installation so users can load the app after the initial session expires. Error handling, especially for failed requests to the API, should be handled and surfaced to the merchant. Adding tests once you get to a state you are reasonably happy with helps keep regressions at bay.
