我正在寻找完全相同的简单性，要求文件从任何级别，我发现模块-别名。

安装:

npm i --save module-alias

打开你的包裹。Json文件，在这里你可以为你的路径添加别名，例如。

"_moduleAliases": {
 "@root"      : ".", // Application's root
 "@deep"      : "src/some/very/deep/directory/or/file",
 "@my_module" : "lib/some-file.js",
 "something"  : "src/foo", // Or without @. Actually, it could be any string
}

使用你的别名只需:

require('module-alias/register')
const deep = require('@deep')
const module = require('something')

在Browserify手册中有一个非常有趣的章节:

avoiding ../../../../../../.. Not everything in an application properly belongs on the public npm and the overhead of setting up a private npm or git repo is still rather large in many cases. Here are some approaches for avoiding the ../../../../../../../ relative paths problem. node_modules People sometimes object to putting application-specific modules into node_modules because it is not obvious how to check in your internal modules without also checking in third-party modules from npm. The answer is quite simple! If you have a .gitignore file that ignores node_modules: node_modules You can just add an exception with ! for each of your internal application modules: node_modules/* !node_modules/foo !node_modules/bar Please note that you can't unignore a subdirectory, if the parent is already ignored. So instead of ignoring node_modules, you have to ignore every directory inside node_modules with the node_modules/* trick, and then you can add your exceptions. Now anywhere in your application you will be able to require('foo') or require('bar') without having a very large and fragile relative path. If you have a lot of modules and want to keep them more separate from the third-party modules installed by npm, you can just put them all under a directory in node_modules such as node_modules/app: node_modules/app/foo node_modules/app/bar Now you will be able to require('app/foo') or require('app/bar') from anywhere in your application. In your .gitignore, just add an exception for node_modules/app: node_modules/* !node_modules/app If your application had transforms configured in package.json, you'll need to create a separate package.json with its own transform field in your node_modules/foo or node_modules/app/foo component directory because transforms don't apply across module boundaries. This will make your modules more robust against configuration changes in your application and it will be easier to independently reuse the packages outside of your application. symlink Another handy trick if you are working on an application where you can make symlinks and don't need to support windows is to symlink a lib/ or app/ folder into node_modules. From the project root, do: ln -s ../lib node_modules/app and now from anywhere in your project you'll be able to require files in lib/ by doing require('app/foo.js') to get lib/foo.js. custom paths You might see some places talk about using the $NODE_PATH environment variable or opts.paths to add directories for node and browserify to look in to find modules. Unlike most other platforms, using a shell-style array of path directories with $NODE_PATH is not as favorable in node compared to making effective use of the node_modules directory. This is because your application is more tightly coupled to a runtime environment configuration so there are more moving parts and your application will only work when your environment is setup correctly. node and browserify both support but discourage the use of $NODE_PATH.

你可以在app.js中定义这样的东西:

requireFromRoot = (function(root) {
    return function(resource) {
        return require(root+"/"+resource);
    }
})(__dirname);

然后任何时候你想从根目录中要求一些东西，无论你在哪里，你只需要使用requireFromRoot而不是普通的require。到目前为止对我来说还不错。

在我看来，实现这一点最简单的方法是在应用程序启动时在node_modules/app(或任何你称之为它的地方)创建一个指向../app的符号链接。然后你可以调用require("app/my/module")。符号链接在所有主要平台上都可用。

然而，你仍然应该把你的东西分成更小的、可维护的模块，这些模块通过npm安装。你也可以通过git-url安装你的私有模块，所以没有理由有一个单一的应用程序目录。

我认为你不需要用你描述的方式来解决这个问题。如果您想在大量文件中更改相同的字符串，请使用sed。在你的例子中，

find . -name "*.js" -exec sed -i 's/\.\.\/\.\.\//\.\.\//g' {} +

/../变成了../

或者，您可以要求配置文件存储包含库路径的变量。如果您将以下文件存储为config.js在示例目录中

var config = {};
config.path = '../../';

在你的例子文件中

myConfiguration = require('./config');
express = require(config.path);

您将能够从一个文件控制每个示例的配置。

这只是个人喜好。

在您自己的项目中，您可以修改根目录中使用的任何.js文件，并将其路径添加到进程的属性中。env变量。例如:

// in index.js
process.env.root = __dirname;

之后，您可以在任何地方访问该属性:

// in app.js
express = require(process.env.root);
