Overview

A lightweight opinionated router to bridge function call and http api. It helps to standardize the way to define input and output of a service.

Features

• Auto generate openapi doc from code reflection
• Use function signature to define input and output
• Type safe without struct tags

Usage

Hello world example: main.go.

RPC style example: main.go.

Check the examples folder.

Read the tests for details.

Benchmark

Without any optimization, goapi is about 7% slower than echo for the simplest usage. This benchmark is only for avoiding drastic performance changes, the real performance depends on the complexity of the service.
