Web Payments Quickstart

LICENSE CI

Quickstart for using Square's Web Payments SDK

Getting Started

Start by cloning this repository.

git clone https://github.com/square/web-payments-quickstart
cd web-payments-quickstart

Install Node.js which will include npm. This repository contains an .nvmrc file if you use nvm to manage your node versions.

Then, to install dependencies run:

npm install

Run the development server.

npm run dev

Finally, open http://localhost:3000.

Credentials

Before you can take a payment, you'll need to configure your developer credentials which can be found in the Developer Dashboard.

Copy .env.exampleto .env.sandbox

cp .env.example .env.sandbox

Define SQUARE_ACCESS_TOKEN with your Sandbox Access Token from the Developer Dashboard.

SQUARE_ACCESS_TOKEN=eX@mpl3_t0k3n

Restart your server to use this new value.

Remember: Do not add your access tokens to git!

Development

Setup

When contributing to this project, you'll want to use the version of Node as defined by .nvmrc. You can use nvm to install the correct version:

nvm install $(cat .nvmrc)

Follow the "Getting Started" instructions above to install dependencies and verify your local server starts properly.

Testing

You can run all linters, tests, and builds like CI with npm test.

Linting

You can run all linters with npm run lint.

ESLint

ESLint analyzes the code to find and fix problems. We use eslint-plugin-square for out-of-the-box configuration.

npm run lint:eslint
Fixing warnings and errors automatically

ESLint can sometimes fix warnings and errors automatically for you with its --fix option.

npm run lint:eslint --fix

Prettier

Prettier is an opinionated code formatter. We use @square/prettier-config for those opinions.

npm run lint:prettier
Fixing code style issues

If after running npm run lint:prettier you get a warning like, "Code style issues found in the above file(s). Forgot to run Prettier?", you can have Prettier fix them.

npm run lint:prettier:fix

Continuous Integration

GitHub Actions is used for our CI/CD workflows. See .github/workflows for details.
