使用带有咕噜声的babel递归地将ES6转换为ES5

Question

My grunt file is as follows :

module.exports = function(grunt) {
require('load-grunt-tasks')(grunt);
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
clean: {
  js: ['src/*.min.js']
},
babel: {
   files: {
       expand: true,
       src: ['src/*.js','src/*/*.js','src/*/*/*.js'],
       ext: '-modified.js'
   },
   options: {
       sourceMap: false,
       presets: ['babel-preset-es2015']
   }
},
 watch: {
  tasks: ['babel']
}

});
grunt.registerTask('default', ['clean','babel']);
};

Is there a better way to configure "src" this so that it would recursively find out the js file within src folder and subfolders and transpile those file:

 src: ['src/*.js','src/*/*.js','src/*/*/*.js']

Answer 1

Those three globbing patterns:

src: ['src/*.js','src/*/*.js','src/*/*/*.js']

...can be replaced with one:

src: ['src/**/*.js']

See the text that reads:

All most people need to know is that foo/*.js will match all files ending with .js in the foo/ subdirectory, but foo/**/*.js will match all files ending with .js in the foo/ subdirectory and all of its subdirectories.

... in the Globbing patterns of the grunt documentation.
