I have a function which get me all the files in folder recursively but i want to sort them by only few specific extension , I know i can use glob but how do i do that using fs in node
const fs = require('fs');
function getFiles (dir, files_){
files_ = files_ || [];
var files = fs.readdirSync(dir);
for (var i in files){
var name = dir + '/' + files[i];
if (fs.statSync(name).isDirectory()){
getFiles(name, files_);
} else {
files_.push(name);
}
}
return files_;
}
console.log(getFiles('D:/sample'))
You could add conditional logic before pushing the files into files_ array, and then using string methods to check the last 4 elements of files[i] if it matches a certain extension, and if it does, proceed to push that file into files_.
const fs = require('fs');
function getFiles (dir, files_) {
files_ = files_ || [];
var files = fs.readdirSync(dir);
var parseThese = [".txt", ".pdf", ".csv"];
for (var i in files) {
var name = dir + '/' + files[i];
var extension = "";
if (fs.statSync(name).isDirectory()) {
return getFiles(name, files_);
}
extension = files[i].slice(-4);
if (parseThese.includes(extension)) {
return files_.push(name);
}
}
return files_;
}
console.log(getFiles('D:/sample'))
It's not using the FS module, but perhaps this could work.
