plugin-babel-jsx

SystemJS plugin that uses Babel for jsx transformation. Includes hot reload for React components.

Notes

This plugin is really straightforward. It will attempt to use whatever babelOptions you've configured for systemjs and fallback to some defaults, {stage: 0, optional: ['runtime']}, when calling babel.transform for the translation. It has only one dependency, babel-plugin-react-hot, added to babel.transform's options.plugins, which of course exists to support hot reloading of React components by default. You can use systemjs-reload to reload modules and babel-plugin-react-hot will handle the React hot reloading portion of it for you.

Builds/bundles have not yet been tested with all of this, but in development, all of this seems to handle everything thrown at it. Some logic also needs to be added to babel-plugin-react-hot to exclude the hot reload code from production builds. Tests will probably also eventually be added to everything, but so far it's all pretty straightforward. Maybe we'll find out that people have some interesting edge cases that require tests sooner rather than later.

Installation

jspm install jsx=github:loggur/plugin-babel-jsx

or

jspm install jsx=npm:plugin-babel-jsx

Usage

import someComponent from 'some-component.jsx!';

Or if you want to import from some-component.jsx instead of some-component.jsx!, you can configure System along these lines:

System.config({
  "baseURL": "./",
  "defaultJSExtensions": true,
  "transpiler": "babel",
  "babelOptions": {
    "stage": 0,
    "optional": [
      "runtime"
    ]
  },
  "paths": {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*"
  },
  "packages": {
    ".": {
      "defaultExtension": "js",
      "main": "src/main",
      "meta": {
        "*.jsx": {
          "loader": "jsx"
        }
      }
    }
  }
});
