How to include multiple file extensions with 'glob.sync' in NodeJS?

Question

Can anyone please suggest how to add multiple file extensions with the glob.sync method.

Something like:

const glob = require('glob');
let files = glob.sync(path + '**/*.(html|xhtml)');

Thank you :)

You can use this (which most shells support as well):

glob.sync(path + '**/*.{html,xhtml}')

Or this one:

glob.sync(path + '**/*.@(html|xhtml)')

EDIT: I initially also suggested this pattern:

glob.sync(path + '**/*.+(html|xhtml)')

However, this will also match files that have .htmlhtml as extension (plus any other combination of html and xhtml, in single or multiple occurrences), which is incorrect.

What is the difference between the both? – Murial

@JaiSaravanan @(PATTERN) matches files that have PATTERN in their name exactly once, +(PATTERN) matches files that have PATTERN in their name at least once (so my example of *.+(html|xhtml) also matches files that end with .htmlhtml, which is incorrect). – Worcester
