README

GoWorkshop

GoWorkshop is a RESTful service that exposes a couple of related resources:

  • courses represent a specific workshop course with start and end times and a location.
  • registrations represent a registration to a course with details about the attendee.

The service implementation makes use of the HashiCorp memdb package to store data in memory.

Security

The APIs are secured with JWT, the session resource exposes a Login action that can be used to retrieve tokens in exchange for email and password. The flow is:

  1. Client makes request to /token using basic auth
  2. Client reads content of Authorization response header
  3. Client sets Authorization header of requests to courses and registrations resources

The database fixtures include a user with email email and password password.

Swagger

The public resource serves the Swagger definition of the service at /swagger.json. It also defines a CORS policy which lets browsers from any origin retrieve the corresponding JSON file.

This makes it possible to load the Swagger spec in Swagger UI on a development laptop for example.

Usage

Start the Service

Build and run the service:

go generate
go build -o gow
./gow

This should print something like:

Use the Generated Client

Use the client to make requests:

cd ./tool/goworkshop-cli
go build -o gowc
./gowc --help

Login with:

gowc --user=email --password=password login session -v

Note the value of the Authorization header, use it with:

gowc --token=$token list courses

See the tool contextual help for calling other APIs, for example:

gowc list --help
Read the Docs

Open a browser and point it at http://localhost:8080/swagger/. This will serve the swagger specification of the API.
