in my Nodejs project, i have a folder named input that contains green-1.png, green-2.png, green-3.png,red-1.png, red-2.png, red-3.png files
i want to read the input directory and grab only the all the green files.
i tried this code :
const { promisify } = require('util')
const readdir = promisify(fs.readdir)
const files = await readdir('../input')
it works fine but it gets me all green and red files from input folder.
how can i get only all the green ones?
fs.readdir will get all the contents of a folder. There is no way to filter the files in the function.
The best you can do is filter the files to those that are green
const filteredFiles = files.filter((f) => f.includes('green'));
