This the code associated with the workshop for That Conference, WI 2023.
This contains the basic hello world code that verifies if the toolchain and the editor is setup correctly.
Lets write a module with a unit test and call it from the module that has the main function.
Add tokio and we discuss how the runtime is distinct from the language even
though the language has support for async await. We'll expand the tokio::main
macro to see how the task is setup.
We now add Axum and start a http server. We use path parameters and see how the Axum extractors work. We also see how we can test handlers independently and how to test handlers and the router.
Step 4 adds state and demonstrates how we can nest routers for API. We also
introduce debug_handler for better error messages during development.
Step 5 adds SQLX with migrations a single model and unit tests for testing DAOs. We see how we can use the State extractor to pass in a database connection pool to use it in our extractors.
Step 6 adds error handling to eliminate unwrap() calls from our handlers and
have our handlers be fallible.
We write a custom extractor to process the JWT token from the header and accessing it from the handler. We also setup logging with tracing_subscriber and how we can add a trace layer middleware.
