NodeJS - fs.exists() throws error but file is there?

}

I try to check if a file (a css-file for example) is existing on the server:



// parse url and extract URL path
var pathname = url.parse(req.url).pathname;


fs.exists(pathname, function (exist) {

// if the file is not found, return 404
if(!exist) {
console.log('NOT EXISTING: '+pathname);
res.statusCode = 404;
res.end(`File ${pathname} not found!`);
return;
}

..... blah blah
}


the file is there but the output is:
NOT EXISTING: /assets/css/bootstrap.min.css



what am I doing wrong?

  • @cenkebret .. yes the executed-js-file is in the root where also the assets-folder is

  • Is 'pathname' the full path or a relative path to the root? If its the later then it will fail as the fs.exists expects the full path.

Try adding __dirname infront of you path:



var pathname = url.parse(req.url).pathname;



fs.exists(__dirname + pathname, function (exist) {

// if the file is not found, return 404
if(!exist) {
console.log('NOT EXISTING: '+pathname);
res.statusCode = 404;
res.end(`File ${pathname} not found!`);
return;
}

..... blah blah
}


When the path starts with / NodeJS will look for a file, starting from the root of your OS. By providing __dirname you are telling NodeJS to search from your current directory.
