cuadrante-codemods

Code modifiers using jscodeshift

Thanks to Node v6 now we don't need babel to run ES2015 in our servers. In that case, if you don't trading off the nice ES2015 modules for good old commonJS, you can run this script to liberate your server from a build process.

Requirements

• Node v6+
• npm install -g jscodeshift

Usage

• cd into your project directory
• npm install cuadrante-codemods
• jscodeshift -t <codemod-script> <path>

Example

Using find to loop through al the javascript files

• find . -name '*.js' -print | xargs jscodeshift -t node_modules/cuadrante-codemods/lib/es2015modules-to-commonjs.js

Will do the following

-import fs from 'fs'
+const fs = require('fs');

-import {getWhatever, findWhatever} from 'library'
+const {getWhatever, findWhatever} = require('library');

-import settings from './settings';
+const settings = require('./settings');

-import homeRoute from './routes/home';
+const homeRoute = require('./routes/home');

-import App from './routes/App';
+const App = require('./routes/App');

-import stockOptionsGameRoute from './routes/stock-options-game';
+const stockOptionsGameRoute = require('./routes/stock-options-game');

-export function wawa() { return 0;  }
+exports.wawa = function wawa() {
+  return 0;
+};

-export default (req, res) => { return true }
+module.exports = (req, res) => {
+  return true
+};

-export const MARKER_REMOVED_OUT = 'MARKER_REMOVED_OUT';
+exports.MARKER_REMOVED_OUT = 'MARKER_REMOVED_OUT';
