Wisp Example: Working with other formats#

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

This example shows how to read and return formats that do not have special support in Wisp. In this case we'll use CSV, but the same techniques can be used for any format.

This example is based off of the "Hello, World!" example, and uses concepts from the routing example so read those first. The additions are detailed here and commented in the code.

gleam.toml file#

The gsv CSV package has been added as a dependency.

app/router module#

The handle_request function has been updated to read a string from the request body, decode it using the gsv library, and return some CSV data back to the client.

app_test module#

Tests have been added that send requests with CSV bodies and check that the expected response is returned.
