find files by extension, *.html under a folder in nodejs

Question

I\'d like to find all *.html files in src folder and all its sub folders using nodejs. What is the best way to do it?

var folder = \'/project1/src\';
var ex         


        

Answer 1

Can't add a comment because of reputation, but notice the following:

Using fs.readdir or node-glob to find a wildcard set of files in a folder of 500,000 files took ~2s. Using exec with DIR took ~0.05s (non recursive) or ~0.45s (recursive). (I was looking for ~14 files matching my pattern in a single directory).

So far, I have failed to find any nodejs implementation which uses low level OS wildcard searching for efficiency. But the above DIR/ls based code works wonderfully in windows in terms of efficiency. linux find, however, will likely be very slow for large directories.

What, hang on?! ... Okay ya, maybe this makes more sense to someones else too.

[nodejs 7 mind you]

fs = import('fs');
let dirCont = fs.readdirSync( dir );
let files = dirCont.filter( function( elm ) {return elm.match(/.*\.(htm?html)/ig);});

Do whatever with regex make it an argument you set in the function with a default etc.
