|
||||
|
||||
### Added
|
||||
|
||||
- feat: Add new `IdentifierRequiredError` class for missing identifiers.
|
||||
- feat: Add the option to use the decorators without passing the identifier: In this case, the identifier will be the class name (register) or the property name (inject).
|
||||
- Add pre release building to release workflow on dev/* branches an version changes.
|
||||
|
||||
|
||||
### Deprecated
|
||||
|
||||
|
||||
### Removed
|
||||
|
||||
- feat!: Disable `experimentalDecorators` and `emitDecoratorMetadata` in the `tsconfig.json` file to reflect the change to the stable decorators api.
|
||||
|
||||
### Fixed
|
||||
|
||||
- feat!: Update `Register`, `RegisterInstance` and `Inject` decorators to reflect the change to the stable decorators api.
|
||||
- feat!: Update `Inject` Decorator typing to reflect the correct property type.
