Wisp Example: Hello, world!#

gleam run   # Run the server
gleam test  # Run the tests

This example shows a minimal Wisp application, it does nothing but respond with a greeting to any request.

The project has this structure:

├─ src
│  ├─ app
│  │  ├─ router.gleam
│  │  └─ web.gleam
│  └─ app.gleam
└─ test
   └── app_test.gleam

In your project app would be replaced by the name of your application.

app module#

The entrypoint to the application. It performs initialisation and starts the web server.

app/web module#

This module contains the application's middleware stack and any custom types, middleware, and other functions that are used by the request handlers.

app/router module#

This module contains the application's request handlers. Or "handler" in this case, as there's only one!

app_test module#

The tests for the application.
