#Few Line of Hack Code Make React-Native Run on Windows

While React-Native just add support of Android,yet officeally they just only support on OSX.

After a few hours of debugging, I find a simple way of let React-Native run on Windows.

Make sure all requirements were all setup following this:

Then initilize the project following this:

The react-native run-android should deploy the app into you phone or AVD

While using 'react-native start' to run the dev server you may get some error couse it runs a bash file, goto /node_modules/react-native/local-cli/run-package.js,and change it to

'use strict';

var path = require('path');
var child_process = require('child_process');

module.exports = function(newWindow) {
  if (newWindow) {
    child_process.spawnSync('open', [
      path.resolve(__dirname, '..', 'packager', 'launchPackager.command')
    ]);
  } else {
    child_process.spawn('node', [
        path.resolve(__dirname, '..', 'packager', 'packager.js'),
        '--projectRoots',
        process.cwd(),
      ], {stdio: 'inherit'});
  }
};

Skip the bash and run the nodejs script instead.

Then the problem shows, fix it, already make a pull request facebook/react-native#2787

Finally get A blank Activity,try adb logcat fetch the error log find out that, while the app load js from

ip:8081/index.android.bundle?platform=android Then get moudle load error.

Because some the moudle path be resolve as "path\\path\\package",and while the were define where "path\path\package".

Goto project\node_modules\react-native\packager\react-packager\src\DependencyResolver\index.js

function defineModuleCode({moduleName, code, deps}) {
  deps = deps.replace(/\\\\/g,'\\');
  return [
    `__d(`,
    `'${moduleName}',`,
    `${deps},`,
    'function(global, require, module, exports) {',
    `  ${code}`,
    '\n});',
  ].join('');
}

Since the moudle system were a litte bit complicate, this may not be the best solution, and neet more test before a pull request,but I think it will get you play around.
