Examples

Runnable examples for learning Wyrly DI.

The Wyrly repository includes runnable examples. Each example is one scenario and one learning goal.

Recommended learning order

1. Start with core examples.
2. Learn graph inspection and validation.
3. Move to the adapter that matches your framework.

Core examples

Folder	Topic	Run
examples/basic-ddd	tokens, @Injectable, scoped lifetimes, disposal	deno task example:basic-ddd
examples/explicit-deps	explicit register({ deps }) without decorators	deno task example:explicit-deps
examples/provider-patterns	useValue, useFactory, useExisting	deno task example:provider-patterns
examples/dependency-graph	inspect() and validate()	deno task example:dependency-graph

Run all core examples:

Use examples as composition-root references

The examples are intentionally small. Use them to see where provider registration belongs, how request scopes are created, and how framework code should hand off to application use cases.
