nodejs batch modify file encoding format_node.js

Summary:
Recently, when I was making a manual, I encountered a problem of "garbled documents". After checking the files, I found that the file encoding was wrong. There were more than 100 files in total. If you use an editor to save them as utf8, it would be tragic. So I wrote a program to modify the file encoding format in batches.

Code:

Copy code The code is as follows:

/**
* Modify the file encoding format, for example: GBK to UTF8
* Support multi-level directories
* @param {String} [root_path] [File path that needs to be transcoded]
* @param {Array} [file_type] [File format that needs to be transcoded, such as html file]
* @param {String} [from_code] [File encoding]
* @param {String} [to_code] [Target encoding of the file]
​*/
//Introduce package
var fs = require('fs'),
iconv = require('iconv-lite');
//Global variables
var root_path = './html',
File_type = ['html', 'htm'],
From_code = 'GBK',
to_code = 'UTF8';
/**
* Determine whether the element is in the array
* @date 2015-01-13
* @param {[String]} elem [the element to be found]
* @return {[bool]} [description]
​*/
Array.prototype.inarray = function(elem) {
"use strict";
var l = this.length;
while (l--) {
If (this[l] === elem) {
       return true;
}
}
return false;
};
/**
* Transcoding function
* @date 2015-01-13
* @param {[String]} root [encoding file directory]
* @return {[type]} [description]
​*/
function encodeFiles(root) {
"use strict";
var files = fs.readdirSync(root);
files.forEach(function(file) {
var pathname = root '/' file,
​​ stat = fs.lstatSync(pathname);
If (!stat.isDirectory()) {
var name = file.toString();
If (!file_type.inarray(name.substring(name.lastIndexOf('.') 1))) {
         return;
}
            fs.writeFile(pathname, iconv.decode(fs.readFileSync(pathname), from_code), {
encoding: to_code
}, function(err) {
If (err) {
            throw err;
}
});
} else {
encodeFiles(pathname);
}
});
}
encodeFiles(root_path);

Summary:
The above program supports multi-level directories, and the same file cannot be operated multiple times, otherwise garbled characters will appear.
