dirflat is a very basic function to recursively fetch all files in a directory, including sub-directories.
File structure:
.
+-- foo.txt
+-- bar.js
+-- index.js
+-- _test
| +-- foo.js
| +-- bar.txt
index.js
const dirFlat = require("dirflat");
dirFlat("./").then(console.log);
// ouputs ["./foo.txt", "./bar.js", "./index.js", "./test/foo.js", "./test/bar.txt"]
