di 1.0.0

Dependency Injection framework

1.0.0

Starting with this release DI is following semver.

Bug Fixes

• Key: fixed bugs caused by hashCode collisions, and docs cleanup (f673267d, #94)
• circular deps: Improve error messages (4ccdb1f0)

Performance Improvements

• Key: don't use Map.putIfAbsent -- too slow (0930b377)
• injector: use separate structures to allow compiler optimizations (f7b8af92)

0.0.40

Bug Fixes

• module: correctly handle null value binding (ada47b36, #93)

0.0.39

Bug Fixes

• transformer: Exception on parameterized types with implicit constructors (ed0a2b02)

Features

• module: new binding syntax (36357b5c, #90)

Breaking Changes

Module has a new API:

new Module()
    ..bind(Foo, toValue: new Foo())
    ..bind(Foo, toFactory: (i) => new Foo())
    ..bind(Foo, toImplementation: FooImpl);

Old methods type, value and factory were deprecated and will be removed in the next release.

0.0.38

Fixes

• key: made Key part of di.dart again (fe390ddf)

0.0.37

Combined with previous release (0.0.36) injector is on average 2x faster.

Bug Fixes

• warnings: refactored injector to fix analyzer warnings (7d374b19)

Performance Improvements

• injector:
  • Make resolving a linked-list stored with the frame (c588e662)
  • Do not closurize methods. (5f47cbd0)
  • Do not check the circular dependency until we are 30 deep. (1dedf6e3)
  • Track resolving keys with the frame. (17aeb4df)
• resolvedTypes: minor performance inmprovement in resolvedTypes (ba16bde5)

0.0.36

Performance Improvements

• injector:
  • skip _checkKeyConditions in dart2js (6763552a)
  • +29%. Use an array for type lookup instead of a map.
