我如何要求在node.js文件夹中的所有文件?
需要像这样的东西:
files.forEach(function (v,k){
// require routes
require('./routes/'+v);
}};

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;

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
其他回答
如果你在example ("app/lib/*.js")目录中包含了*.js的所有文件:
在app/lib目录下
example.js:
module.exports = function (example) { }
示例- 2. - js:
module.exports = function (example2) { }
在目录app中创建index.js
index.js:
module.exports = require('./app/lib');

可以使用:https://www.npmjs.com/package/require-file-directory
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。
基于@tbranyen的解决方案,我创建了一个index.js文件,在当前文件夹下加载任意javascript作为导出的一部分。
// Load `*.js` under current directory as properties
// i.e., `User.js` will become `exports['User']` or `exports.User`
require('fs').readdirSync(__dirname + '/').forEach(function(file) {
if (file.match(/\.js$/) !== null && file !== 'index.js') {
var name = file.replace('.js', '');
exports[name] = require('./' + file);
}
});
然后,您可以从其他任何地方要求这个目录。
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()
