A plugin for Gatsby.js that adds the necessary Stripe Checkout JavaScript files, to bring e-commerce functionality to a Gatsby static site. This, and the other plugins I've created for Gatsby, are my ongoing foray into contributing to open-source projects. These projects have helped familiarize myself with what it takes to maintain an open source NPM package that others rely on: answering and resolving issues, keeping dependencies up to date, and updating the plugin as both Gatsby and Stripe evolve.
