Creating a Beer Library with React and BreweryDB
I’ve been learning and working with React for about six months now and I never posted my first React project outside of a tutorial. It’s certainly not the prettiest code I’ve written, but I learned A LOT just by getting started and putting something out there.
Some Things I Learned
- To start, React! This project helped me learn some basic React concepts
- How to create server proxy with Express
- HTTP requests
- Setting server environment variables
- Continuous deployment to a Node server (Heroku)
How I Got Started
After taking several React tutorials, I felt I had a good understanding of the fundamentals to get started on my project. I searched the web for free APIs – being sure to look for something that interested me. After searching the web, I discovered BreweryDB. I thought “Beer? React?” what a fun combination to learn something with.
I set out to make a searchable beer library using the available data from the BreweryDB API. I signed up for a free sandbox developer account and got started. Shortly after configuring my create-react-app boilerplate, I began testing HTTP request methods to BreweryDB in Postman to make sure my API key was working.
After some successful requests, I returned to the BreweryDB documentation for my next steps. I discovered in the documentation that the API did not support requests from front-end clients and that I needed to proxy all requests from a backend technology. Fortunately for me, I recently took a course on Node.js and how to build RESTful APIs.
Since it’s best practice to host your API and your application separately, I created a separate project locally for my API proxy and configured the routes. Since the functionality of my application was going to be read-only, I configured my routes to handle GET requests to:
- GET all beers
- GET a random beer
- GET categories
- GET a search term
After my routes were completed, I configured the React application to use the new API proxy. After I finished building the React components, I signed up for a free account on Heroku. I created my applications (projects) on Heroku, one to host the API and one to host the React application. I connected both Heroku applications to my Github repositories and set them to automatically deploy when a commit is made to the production branches. Voila, my app was live!
