Hello I am trying to find first file with given filename ( piece of filename ).
It works fine but it take a while to take result
There is code
const fs = require("fs");
const dirCheckIn =
"\\\\192.168.2.4\\Photos";
exports.checkUploadedFiles = (req, res) => {
let fileName = req.params.filename;
const getAllFiles = function (dirPath, arrayOfFiles) {
files = fs.readdirSync(dirPath);
arrayOfFiles = arrayOfFiles || [];
files.forEach(function (file) {
if (fs.statSync(dirPath + "/" + file).isDirectory()) {
arrayOfFiles = getAllFiles(dirPath + "/" + file, arrayOfFiles);
} else {
arrayOfFiles.push(file);
}
});
return arrayOfFiles;
};
const uploadedFiles = getAllFiles(inventDirCheckIn);
console.log(uploadedFiles)
let result = uploadedFiles.find(
(result) => result.startsWith(fileName));
if (!result) {
res.send('nothing found')
} else if (result) {
res.send(result)
}
}
It works fine but for example if I have over 7000 photos it takes about 5 sec to get result. Maybe there is smarter solution?
How can I make it in better way? I want to check if file is uploaded into dir Photos.
I got simple api route /api/getUploadedFiles/:filename
Also I want use startsWith because sometimes I do not know full name of file
/**
*
* @param filePath path to file which is to be checked if it exists.
*/
private checkFileExistsSync(filePath: string) {
let flag = true;
try {
fs.accessSync(filePath, fs.constants.F_OK);
} catch (e) {
flag = false;
}
return flag;
}
// Example usage
// path to the file
const dirCheckIn =
"\\\\192.168.2.4\\Photos";
if (checkFileExistsSync(dirCheckIn)) {
// if the file exists do something...
}
if (!checkFileExistsSync(dirCheckIn)) {
// if the file doesn't exists do something...
}
