Tutorial

This tutorial provides a hands-on introduction to Picodi. We’ll build a simple application step-by-step, demonstrating the core features of the library.

By the end of this tutorial, you will understand:

• How to define basic dependencies.

• How to inject dependencies into your functions using inject() and Provide().

• How to work with dependencies that require setup and teardown (yield dependencies).

• How to use different scopes to manage dependency lifecycles.

• How to handle asynchronous dependencies.

• How to override dependencies for testing or different configurations.
