Tutorial: 07 - Conclusion

Congratulations! You’ve completed the Picodi tutorial.

What You’ve Learned

Through these steps, you’ve gained a practical understanding of Picodi’s core features:

• Defining Dependencies: How simple Python functions (sync and async) act as dependency providers. (Step 1)

• Injection: Using inject() and Provide() to automatically supply dependencies to functions. (Step 1)

• Yield Dependencies: Managing dependency setup and teardown using yield for resources requiring cleanup. (Step 2, Step 4)

• Scopes: Controlling dependency instance lifecycle and caching using NullScope and SingletonScope. (Step 3)

• Async Support: Defining and injecting asynchronous dependencies seamlessly. (Step 4)

• Overrides: Replacing dependency implementations at runtime using picodi.Registry.override(), crucial for testing and configuration. (Step 5)

• Testing: Leveraging overrides and the pytest plugin for effective testing. (Step 6)
