Writing JSON REST APIs in Go (Go from A to Z — Zürich Gophers Meetup)

Klaus Post

Learn how to build robust JSON REST APIs in Go using the standard library, including encoding and decoding, middleware, context, goroutines, error handling, and more.

Key takeaways

Writing JSON REST APIs in Go is straightforward with the standard library.
The encoding/json package is used for encoding and decoding JSON.
Struct tags are used to map JSON fields to Go struct fields.
Middleware is a key concept in Go’s standard library, allowing for easy implementation of features like authentication and error handling.
The net/http package provides a robust HTTP client and server.
Context is a crucial concept in Go, allowing for easy cancellation of requests and timeouts.
Goroutines and channels are used to handle concurrency and asynchronous requests.
Error handling is crucial in Go, and the error type is used to represent errors.
JSON Web Token middleware is available for authentication and authorization.
Go’s standard library provides a robust set of tools for building web applications.
JSON APIs can be built using the standard library, without the need for external frameworks.
Middleware can be used to implement features like authentication, error handling, and logging.
Context can be used to manage request timeouts and cancellation.
Goroutines and channels can be used to handle concurrent requests and asynchronous processing.
Error handling is critical in Go, and the error type is used to represent errors.
Go’s standard library provides a robust set of tools for building web applications, making it easy to get started with building JSON REST APIs.
