Huma Demo

This is a demo of the Huma framework. Huma is a Go library for building web APIs with OpenAPI 3 that are easy to use, easy to understand, and easy to maintain.

The purpose of this demo is to show a simple API, so you won't see a real, complex project with all the bells & whistles and code organization you would expect in a real project. Instead, you'll see a simple API with a few endpoints and some basic functionality, but more than a "hello world" so that we can show off some of the more interesting features built-in to Huma.

Getting Started

Just check out the project and then you can run it:

# Run the server.
$ go run .

Alternatively you can run via Air for hot reloading.

You should see the docs at http://localhost:8888/docs. Use them to create a test channel!

Then you can use Restish or curl to call the API:

# One-time setup
$ brew install danielgtaylor/restish/restish
$ restish api configure demo http://localhost:8888

# List available commands
$ restish demo --help

# List channels (via operation ID or URL)
$ restish demo list-channels
$ restish demo/channels

# Edit the channel you created via your editor. VSCode provides linting &
# completion as you type.
$ restish edit -i demo/channels/my-test-channel

Unit Testing

You can run the unit tests for the API, which are in the main_test.go file:

# Run tests with coverage info
$ go test -cover

SDK Generation

You can also generate an SDK for the API (note the API must be running in another tab):

# One-time setup
$ go install github.com/deepmap/oapi-codegen/v2/cmd/oapi-codegen@latest

# Generate the SDK
$ cd sdk
$ ./generate.sh

Then you can run the demo project using the generated SDK:

# Run the demo project
$ go run ./example

Performance Testing

You can do a quick perfomance test using wrk:

# One-time setup
$ brew install wrk

# Ensure the API is running & you have a channel called `test`, then run:
$ wrk -c 20 -d 10s -t 10 http://localhost:8888/channels/test

During the test you can run htop and use F4 to filter to go run .. Note that you may also want to disable printing requests in the middleware for the perf test.

Things to Demo

Things that could be added to the demo as an exercise:

More formats (e.g. CBOR)
Auto PATCH
Server Sent Events
CLI commands & arguments
