babel-plugin-syntax-typescript

npm install --save-dev @babel/plugin-syntax-typescript

Usage

.babelrc

{
  "plugins": ["@babel/plugin-syntax-typescript"]
}

babel --plugins @babel/plugin-syntax-typescript script.js

require("@babel/core").transform("code", {
  plugins: ["@babel/plugin-syntax-typescript"]
});

boolean, defaults to false.

Forcibly enables jsx parsing. Otherwise angle brackets will be treated as typescript's legacy type assertion var foo = <string>bar;
