Get all files recursively in directories NodejS

I have a little problem with my function. I would like to get all files in many directories. Currently, I can retrieve the files in the file passed in parameters. I would like to retrieve the html files of each folder in the folder passed as a parameter. I will explain if I put in parameter "test" I retrieve the files in "test" but I would like to retrieve "test / 1 / *. Html", "test / 2 / . /.html ":

var srcpath2 = path.join('.', 'diapo', result);
function getDirectories(srcpath2) {
                return fs.readdirSync(srcpath2).filter(function (file) {
                    return fs.statSync(path.join(srcpath2, file)).isDirectory();
                });
            }

The result : [1,2,3]

thanks !

It looks like the glob npm package would help you. Here is an example of how to use it:

File hierarchy:

test
├── one.html
└── test-nested
    └── two.html

JS code:

const glob = require("glob");

var getDirectories = function (src, callback) {
  glob(src + '/**/*', callback);
};
getDirectories('test', function (err, res) {
  if (err) {
    console.log('Error', err);
  } else {
    console.log(res);
  }
});

which displays:

[ 'test/one.html',
  'test/test-nested',
  'test/test-nested/two.html' ]

I've seen many very long answers, and it's kinda a waste of memory space. Some also use packages like glob, but if you don't want to depend on any package, here's my solution.

const Path = require("path");
const FS   = require("fs");
let Files  = [];

function ThroughDirectory(Directory) {
    FS.readdirSync(Directory).forEach(File => {
        const Absolute = Path.join(Directory, File);
        if (FS.statSync(Absolute).isDirectory()) return ThroughDirectory(Absolute);
        else return Files.push(Absolute);
    });
}

ThroughDirectory("./input/directory/");

It's pretty self-explanatory. There's an input directory, and it iterates through that. If one of the items is also a directory, go through that and so on. If it's a file, add the absolute path to the array.

Hope this helped :]

Using ES6 yield

const fs = require('fs');
const path = require('path');

function *walkSync(dir) {
  const files = fs.readdirSync(dir, { withFileTypes: true });
  for (const file of files) {
    if (file.isDirectory()) {
      yield* walkSync(path.join(dir, file.name));
    } else {
      yield path.join(dir, file.name);
    }
  }
}

for (const filePath of walkSync(__dirname)) {
  console.log(filePath);
}

Here's mine. Like all good answers it's hard to understand:

const isDirectory = path => statSync(path).isDirectory();
const getDirectories = path =>
    readdirSync(path).map(name => join(path, name)).filter(isDirectory);

const isFile = path => statSync(path).isFile();  
const getFiles = path =>
    readdirSync(path).map(name => join(path, name)).filter(isFile);

const getFilesRecursively = (path) => {
    let dirs = getDirectories(path);
    let files = dirs
        .map(dir => getFilesRecursively(dir)) // go through each directory
        .reduce((a,b) => a.concat(b), []);    // map returns a 2d array (array of file arrays) so flatten
    return files.concat(getFiles(path));
};
