@babel/plugin-syntax-decorators

Syntax only

It's unlikely you want to use this plugin directly as it only enables Babel to parse this syntax. Instead, use plugin-proposal-decorators to both parse and transform this syntax.

Installation

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

Usage

Via `.babelrc` (Recommended)

.babelrc

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

Via CLI

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

Via Node API

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

Options

`legacy`

boolean, defaults to false.

Use the legacy (stage 1) decorators syntax.

`decoratorsBeforeExport`

boolean, defaults to false.

// decoratorsBeforeExport: true
@decorator
export class Foo {}

// decoratorsBeforeExport: false
export @decorator class Bar {}

This option was added to help tc39 collect feedback from the community by allowing experimentation with both possible syntaxes.
