Awesome metadata emitter for TypeScript. Injects fake decorators in every class with additional information, to be accessed by other libraries and utilities.

• TSON: This library makes automatic serialization and deseralization possible, like GSON for Java.
• ts-mongoose-metadata Generates mongoose schemas automatically from class metadata.
• ts-express-validator Middleware for express that automatically deserializes the body of a request, and checks if the data is valid.

The goal of this project is to offer metadata for all elements in TypeScript, being as simple as possible.

• Class body schema metadata atm:body
  • Visibility (private, protected, public, none) BROKEN IN THIS BRANCH
  • Optionality (question mark token) BROKEN IN THIS BRANCH
  • Primitive members serialization
  • Union types serialization
  • Type alias serialization
  • Array of generic types
  • Type literal serialization
  • Interface type serialization
• Configuration based metadata emit
  • Needs discussion.
• Interface body schema metadata
  • Needs discussion.
• Variable and function metadata
  • Needs discussion.

We use it this way:

In package.json:

{
  "scripts": {
    "compile": "atm"
  }
}

Then instead of compiling using tsc, you compile using

npm run compile
# or
atm

You can get an schema of a class using:

Reflect.getMetadata("atm:body", AnyClass);
