var settings = 
    JSON.parse(
        require('fs').readFileSync(
            require('path').resolve(
                __dirname, 
                'settings.json'),
            'utf8'));

你可以使用process.env.PWD来获取当前应用程序的文件夹路径。

var settings = 
    JSON.parse(
        require('fs').readFileSync(
            require('path').resolve(
                __dirname, 
                'settings.json'),
            'utf8'));

Index.js中包含要导出的模块的任何文件夹

const entries = {};
for (const aFile of require('fs').readdirSync(__dirname, { withFileTypes: true }).filter(ent => ent.isFile() && ent.name !== 'index.js')) {
  const [ name, suffix ] = aFile.name.split('.');
  entries[name] = require(`./${aFile.name}`);
}

module.exports = entries;

这将找到当前目录的根目录下的所有文件，要求并导出与文件名干相同的导出名称的每个文件。

Node.js 10支持ECMAScript模块，其中__dirname和__filename不再可用。

然后，要获得当前ES模块的路径，必须使用:

import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url);

对于包含当前模块的目录:

import { dirname } from 'path';
import { fileURLToPath } from 'url';

const __dirname = dirname(fileURLToPath(import.meta.url));

如果你使用pkg来打包你的应用，你会发现这个表达式很有用:

appDirectory = require('path').dirname(process.pkg ? process.execPath : (require.main ? require.main.filename : process.argv[0]));

process.pkg tells if the app has been packaged by pkg. process.execPath holds the full path of the executable, which is /usr/bin/node or similar for direct invocations of scripts (node test.js), or the packaged app. require.main.filename holds the full path of the main script, but it's empty when Node runs in interactive mode. __dirname holds the full path of the current script, so I'm not using it (although it may be what OP asks; then better use appDirectory = process.pkg ? require('path').dirname(process.execPath) : (__dirname || require('path').dirname(process.argv[0])); noting that in interactive mode __dirname is empty. For interactive mode, use either process.argv[0] to get the path to the Node executable or process.cwd() to get the current directory.
