babel-plugin-transform-typescript
Transform TypeScript into ES.next.
Does not type-check its input. For that, you will need to install and set up TypeScript.
Does not support namespaces or const enums because those require type information to transpile.
Also does not support export = and import =, because those cannot be transpiled to ES.next.
Example
In
const x: number = 0;
Out
const x = 0;
Installation
npm install --save-dev babel-plugin-transform-typescript

{
"plugins": ["transform-typescript"]
}
Via CLI
babel --plugins transform-typescript script.js
