Need to Go REST?

Presentation:
Want to introduce the use of Go into your organization? Implementing some new REST services in Go is a great way to get started. This talk will show you how.

We’ll walk through the implementation of some services that perform CRUD operations on a relational database--PostgreSQL in this case. The services accept and return JSON data.

There are many Go libraries that support doing this. We’ll look at “Gin” for handing HTTP requests and “pq” for interacting with PostgreSQL databases.

One tricky part is enabling Cross-Origin Resource Sharing (CORS) so web apps at different domains from the REST server are allowed to send requests. We’ll see how to configure this.

We’ll test the REST services using Postman.

Finally, we’ll configure the ability to watch source files for changes and automatically rebuild and restart our server.
