A small bare-bones online shop. I wrote this to practice developing a Stripe integration and to explore some technologies that were new to me.
The project is split into distinct frontend and backend components. They communicate via a GraphQL api defined in the common folder.
The backend is written in Go. I use the Ent Framework as an ORM and gqlgen to generate GraphQL scaffolding code. Both of these tools use code generation in order to provide type-safe APIs, as strong type-safety was one of my goals while developing this project.
I was curious to see how well that could be achieved despite Go's simpler type system, and I found the tools a joy to work with. It seems that there is a greater ecosystem developing around code-generation for Go, and I much prefer this to solutions that depend on reflection, as you lose the benefits of strong static typing with reflection-based APIs, making refactoring more difficult, and requiring tests to be more comprehensive.
Use the command cd backend; go generate ./... to regenerate any auto-generated code.
I use the Stripe Go library to handle payments processing with Stripe.
The frontend is a create-react-app Typescript React webapp. I use graphql-codegen to generate well-typed React hooks for communicating with the backend, and React Stripe.js to handle transfering payment details.
Make a file .env in the root directory containing the following environment variables:
STRIPE_PUBLISHABLE_KEYSTRIPE_SECRET_KEY
Then it's just docker-compose up to start the application on localhost:3000.
