If you're looking to accept payments online for your business, you've probably heard of Stripe. Stripe is a popular payment gateway that offers a variety of tools and APIs for developers to easily integrate payments into their applications. In this tutorial, we'll be setting up Stripe with TypeScript to make it even easier to work with Stripe.

Before we begin, it's important to note that we assume you have a basic understanding of TypeScript and how to set up a TypeScript project. If you're not familiar with TypeScript, we recommend checking out the official documentation first.


Step 1: Install Stripe package

To get started, we'll need to install the Stripe package. Open up your terminal and navigate to your project directory. Then run the following command to install the Stripe package: 

npm install stripe


Step 2: Set up Stripe account

If you haven't already, you'll need to create a Stripe account. Go to the Stripe website and sign up for a free account. Once you're signed up, you'll need to obtain your API keys. Head to your dashboard and navigate to "Developers" > "API Keys" and copy both the "Publishable key" and "Secret key".


Step 3: Add Stripe configuration file

Create a new file in your project's root directory called stripe.config.ts. In this file, we'll add the following code:

export const STRIPE_PUBLISHABLE_KEY = 'your_publishable_key_here';
export const STRIPE_SECRET_KEY = 'your_secret_key_here';

Be sure to replace your_publishable_key_here and your_secret_key_here with your own Stripe API keys.


Step 4: Create a TypeScript module for Stripe

Create a new TypeScript module in your project called stripe.ts. This module will contain all of the code related to interacting with Stripe.

import Stripe from 'stripe';
import { STRIPE_SECRET_KEY } from './stripe.config';

const stripe = new Stripe(STRIPE_SECRET_KEY, {
  apiVersion: '2020-08-27',
});

export default stripe;


This module imports the Stripe package we installed earlier and your Stripe secret key from the stripe.config.ts file. It then creates a new instance of the Stripe class and exports it as the default export.


Step 5: Test the integration

To test that everything is working correctly, create a new TypeScript file called index.ts and add the following code:

import stripe from './stripe';

async function testStripe() {
  const paymentIntent = await stripe.paymentIntents.create({
    amount: 1099,
    currency: 'usd',
    payment_method_types: ['card'],
  });

  console.log(paymentIntent);
}

testStripe();

This code imports our stripe module and creates a new paymentIntent object with a total amount of $10.99. The console.log() statement prints the paymentIntent object to the console.

To run this code, open your terminal and navigate to your project directory. Then run the following command:

npx ts-node index.ts

If everything is set up correctly, you should see a response from Stripe with information about the payment intent.

And that's it! You've successfully set up Stripe with TypeScript. From here, you can explore the Stripe API documentation to learn more about the various features and options available to you.
