# TypeScript Decorator metadata collector The `.d.ts` format does not preserve information about the Decorators applied to symbols. Some tools, such as Angular 2 template compiler, need access to statically analyzable information about Decorators, so this library allows programs to produce a `foo.metadata.json` to accompany a `foo.d.ts` file, and preserves the information that was lost in the declaration emit. ## Releasing ``` $ gulp build.tools $ cp tools/metadata/package.json dist/tools/metadata/ $ npm login [angularcore] $ npm publish dist/tools/metadata ```
