使用这个函数，你可以要求一个完整的目录。

const GetAllModules = ( dirname ) => {
    if ( dirname ) {
        let dirItems = require( "fs" ).readdirSync( dirname );
        return dirItems.reduce( ( acc, value, index ) => {
            if ( PATH.extname( value ) == ".js" && value.toLowerCase() != "index.js" ) {
                let moduleName = value.replace( /.js/g, '' );
                acc[ moduleName ] = require( `${dirname}/${moduleName}` );
            }
            return acc;
        }, {} );
    }
}

// calling this function.

let dirModules = GetAllModules(__dirname);

要求所选文件只有名称或全部文件。 不需要绝对路径。 易于理解和使用。

我有一个文件夹/字段的文件与单个类每个，例如:

fields/Text.js -> Test class
fields/Checkbox.js -> Checkbox class

把它放到fields/index.js中，导出每个类:

var collectExports, fs, path,
  __hasProp = {}.hasOwnProperty;

fs = require('fs');    
path = require('path');

collectExports = function(file) {
  var func, include, _results;

  if (path.extname(file) === '.js' && file !== 'index.js') {
    include = require('./' + file);
    _results = [];
    for (func in include) {
      if (!__hasProp.call(include, func)) continue;
      _results.push(exports[func] = include[func]);
    }
    return _results;
  }
};

fs.readdirSync('./fields/').forEach(collectExports);

这使得模块的行为更像在Python中:

var text = new Fields.Text()
var checkbox = new Fields.Checkbox()

在这个glob解决方案上展开。如果你想将所有模块从一个目录导入到index.js中，然后将该index.js导入到应用程序的另一部分，那么就这样做。注意，stackoverflow使用的高亮显示引擎不支持模板文字，因此这里的代码可能看起来很奇怪。

const glob = require("glob");

let allOfThem = {};
glob.sync(`${__dirname}/*.js`).forEach((file) => {
  /* see note about this in example below */
  allOfThem = { ...allOfThem, ...require(file) };
});
module.exports = allOfThem;

完整的示例

目录结构

globExample/example.js
globExample/foobars/index.js
globExample/foobars/unexpected.js
globExample/foobars/barit.js
globExample/foobars/fooit.js

globExample - js操作。

const { foo, bar, keepit } = require('./foobars/index');
const longStyle = require('./foobars/index');

console.log(foo()); // foo ran
console.log(bar()); // bar ran
console.log(keepit()); // keepit ran unexpected

console.log(longStyle.foo()); // foo ran
console.log(longStyle.bar()); // bar ran
console.log(longStyle.keepit()); // keepit ran unexpected

globExample foobars / index . js

const glob = require("glob");
/*
Note the following style also works with multiple exports per file (barit.js example)
but will overwrite if you have 2 exports with the same
name (unexpected.js and barit.js have a keepit function) in the files being imported. As a result, this method is best used when
your exporting one module per file and use the filename to easily identify what is in it.

Also Note: This ignores itself (index.js) by default to prevent infinite loop.
*/

let allOfThem = {};
glob.sync(`${__dirname}/*.js`).forEach((file) => {
  allOfThem = { ...allOfThem, ...require(file) };
});

module.exports = allOfThem;

globExample foobars /无法js。

exports.keepit = () => 'keepit ran unexpected';

globExample foobars / barit js。

exports.bar = () => 'bar run';

exports.keepit = () => 'keepit ran';

globExample foobars / fooit js。

exports.foo = () => 'foo ran';

在安装了glob的项目中，运行node example.js

$ node example.js
foo ran
bar run
keepit ran unexpected
foo ran
bar run
keepit ran unexpected

使用这个函数，你可以要求一个完整的目录。

const GetAllModules = ( dirname ) => {
    if ( dirname ) {
        let dirItems = require( "fs" ).readdirSync( dirname );
        return dirItems.reduce( ( acc, value, index ) => {
            if ( PATH.extname( value ) == ".js" && value.toLowerCase() != "index.js" ) {
                let moduleName = value.replace( /.js/g, '' );
                acc[ moduleName ] = require( `${dirname}/${moduleName}` );
            }
            return acc;
        }, {} );
    }
}

// calling this function.

let dirModules = GetAllModules(__dirname);

我使用节点模块复制到模块来创建一个文件，以需要我们基于nodejs的系统中的所有文件。

我们的实用程序文件的代码是这样的:

/**
 * Module dependencies.
 */

var copy = require('copy-to');
copy(require('./module1'))
.and(require('./module2'))
.and(require('./module3'))
.to(module.exports);

在所有的文件中，大多数函数都被写成export，如下所示:

exports.function1 = function () { // function contents };
exports.function2 = function () { // function contents };
exports.function3 = function () { // function contents };

所以，然后使用文件中的任何函数，你只需要调用:

var utility = require('./utility');

var response = utility.function2(); // or whatever the name of the function is
