What it does
The universal createImplementation DI pattern and all injectable services. Use this skill when the developer is writing any Webiny extension and needs to understand dependency injection, constructor injection, how to access Logger/BuildParams/IdentityContext, how to inject CMS use-cases (list/get/create/update/delete entries), or how the dependencies array works. This is the connective tissue across all extension types -- API, Admin, CLI, and Infrastructure.
Dependency Injection Patterns
TL;DR
Every Webiny extension type uses the same DI pattern: define a class implementing *.Interface, declare dependencies in the constructor, and export via *.createImplementation({ implementation, dependencies }). The DI container automatically provides the required services, ensures type safety, and validates at compile time. This pattern is the connective tissue across all extension types -- API, Admin, CLI, and Infrastructure.
Working Context
This skill applies to both extension developers (working in extensions/) and core developers (working in packages/). The DI pattern is universal, only the import paths differ.
Extensions (extensions/) | Core (packages/) | |
|---|---|---|
createAbstraction | from "webiny/api" or from "webiny/admin" | from "@webiny/feature/api" or from "@webiny/feature/admin" |
createFeature | from "webiny/api" or from "webiny/admin" | from "@webiny/feature/api" or from "@webiny/feature/admin" |
| Factory imports | from "webiny/api/graphql", from "webiny/api/cms/model", etc. | Direct package paths: from "@webiny/handler-graphql/...", from "@webiny/api-headless-cms/..." |
| Catalog paths | Use the Import: path | Use the Source: path |
