在Node 0.12中，现在可以同步执行此操作了:

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

// Buffer mydata
var BUFFER = bufferFile('../public/mydata.png');

function bufferFile(relPath) {
    return fs.readFileSync(path.join(__dirname, relPath)); // zzzz....
}

Fs是文件系统。readFileSync()返回一个Buffer，如果你要求，也可以返回字符串。

Fs正确地假设相对路径是一个安全问题。路径是一种变通方法。

要以字符串形式加载，请指定编码:

return fs.readFileSync(path,{ encoding: 'utf8' });

运行这段代码，它将从文件中获取数据并显示在控制台

function fileread(filename)
{            
   var contents= fs.readFileSync(filename);
   return contents;
}        
var fs =require("fs");  // file system        
var data= fileread("abc.txt");
//module.exports.say =say;
//data.say();
console.log(data.toString());

如果您想知道如何读取目录中的文件，并对其进行操作，请参阅这里。这也向您展示了如何通过power shell运行命令。这是在TypeScript中!我在这方面遇到了麻烦，所以我希望有一天这能帮助到别人。这为我做的是webpack我所有的.ts文件在我的每个目录在一个特定的文件夹，为部署做好准备。希望你能派上用场!

使用路径。加入(__dirname ' / start.html ');

var fs = require('fs'),
    path = require('path'),    
    filePath = path.join(__dirname, 'start.html');

fs.readFile(filePath, {encoding: 'utf-8'}, function(err,data){
    if (!err) {
        console.log('received data: ' + data);
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.write(data);
        response.end();
    } else {
        console.log(err);
    }
});
