Checkout JS is a browser-based application providing a seamless UI for BigCommerce shoppers to complete their checkout. It is also known as Optimized One-Page Checkout, which is currently the recommended checkout option for all BigCommerce stores.

In order to build from the source code, you must have the following set up in your development environment.

• Node >= v16.
• NPM >= v8.
• Unix-based operating system. (WSL on Windows)

One of the simplest ways to install Node is using NVM. You can follow their instructions to set up your environment if it is not already set up.

Once you have cloned the repository and set up your environment, you can start developing with it.

First, you have to pull in the dependencies required for the application.

npm ci

After that, you can make changes to the source code and run the following command to build it.

npm run build

If you are developing the application locally and want to build the source code in watch mode, you can run the following command:

npm run dev

If you want to create a prerelease (i.e.: alpha) for testing in the integration environment, you can run the following command:

npm run release:alpha

After that, you need to push the prerelease tag to your fork so it can be referenced remotely.

Follow this guide for instructions on how to fork and install this app as a Custom Checkout in your store.

If you want to test your checkout implementation, you can run:

npm run dev:server

And enter the local URL for auto-loader-dev.js in Checkout Settings, e.g http://127.0.0.1:8080/auto-loader-dev.js

Everytime a PR is merged to the master branch, CircleCI will trigger a build automatically. However, it won't create a new Git release until it is approved by a person with write access to the repository. If you have write access, you can approve a release job by going to CircleCI and look for the job you wish to approve. You can also navigate directly to the release job by clicking on the yellow dot next to the merged commit.

We currently do not accept Pull Requests from external parties. However, if you are an external party and want to report a bug or provide your feedback, you are more than welcome to raise a GitHub Issue. We will attend to these issues as quickly as we can.
