Node.js to realize bulk removal of BOM file header _node.js

Previous colleagues wrote a tool, but there is a bug, is the original file after the replacement file format into a utf8 BOM, this with the BOM XML under the Mac may not read out, so you need to write a tool to deal with.

In fact, the idea is relatively simple, first traverse the directory, and then read the directory, the first three bytes of the file to remove, and then save the file in utf-8 format, directly on the code bar:)

Copy Code code as follows:

var fs = require (' FS ');


var path = "Target path ...";

function Readdirectory (Dirpath) {
if (Fs.existssync (Dirpath)) {
var files = Fs.readdirsync (Dirpath);

Files.foreach (function (file) {
var FilePath = Dirpath + "/" + file;
var stats = Fs.statsync (FilePath);

            if (stats.isdirectory ()) {
                 console.log (' \ n ' read directory: \ n ', FilePath , "\ n");
                Readdirectory ( FilePath);
           } else if (Stats.isfile ()) {
                 var buff = Fs.readfilesync (filePath );
                if (buff[0). ToString. toLowerCase () = = "EF" && buff[1].tostring. toLowerCase () = = "BB" && buff[2].tostring ( toLowerCase () = = "BF") {
                    //ef BB BF 239 187 191
  &Nbsp;                 Console.log (' \ Discovery BOM file: ', FilePath, ' \ n ');

Buff = Buff.slice (3);
Fs.writefile (FilePath, buff.tostring (), "UTF8");
}
}
});

} else {
Console.log (' Not Found Path: ', Dirpath);
}
}

Readdirectory (path);
