I'm working on creating a static node.js server - node.js

Question

I am working on creating a static node.js server that just serves up the plain html, css, and javascript that is in the specified directory. I am trying to get the server to read every subdirectory and route the url to the file it specifies. However it only reads the root directory.
var fs = require('fs');
var array = fs.readdirSync(__dirname);
function getAllSub(array){
for (i = 0; i < array.length; i++){
if (array[i].indexOf(".") == (-1))
{
array = array.concat(array[i] + "/" + fs.readdirSync(__dirname + "/" + array[i]));
}
if (array[i].indexOf("/") != (-1)){
var foldcon = array[i].substr(array[i].indexOf("/") + 1);
var folder = array[i].substr(0, array[i].indexOf("/"));
foldcon = foldcon.split(",");
for (n = 0; n < foldcon.length; n++){
foldcon[n] = folder + "/" + foldcon[n]
if (foldcon[n].indexOf(".") == (-1)){
console.log([foldcon[n]]);
foldcon[n] = getAllSub([foldcon[n]]);
}
}
array.splice(i, 1, foldcon);
}
}
return array;
}
array = getAllSub(array);
console.log(array);
Right now this code reads the directory and it recognizes if an item in the array of files is a folder, however it doesn't add the files from the subdirectories into the array properly. Right now it kinda goes all infinite recursion, and I can't really figure out how to stop it.
This isn't meant to be something I am actually going to use, I just thought it would be a good project to work on to introduce myself to the basics of node.js

Answer 1

I know it's late, but this is the right answer for a recursive solution to reading file paths in sub-folders:
var fs = require("fs");
/**
* Recurse through a directory and populate an array with all the file paths beneath
* #param {string} path The path to start searching
* #param {array} allFiles Modified to contain all the file paths
*/
function readdirSyncRecursive(path, allFiles) {
var stats = fs.statSync(path);
if (stats.isFile()) {
// base case
allFiles.push(path);
} else if (stats.isDirectory()) {
// induction step
fs.readdirSync(path).forEach(function(fileName) {
readdirSyncRecursive(path + "/" + fileName, allFiles);
});
}
}
var allFiles = [];
readdirSyncRecursive("/path/to/search", allFiles);
console.info(allFiles);

var fs = require('fs');
var array = fs.readdirSync(__dirname);
for (i = 0; i < array.length; i++){
if (array[i].indexOf(".") == (-1))
{
// you need to use the return value from concat
array = array.concat(array[i] + "/" + fs.readdirSync(__dirname + "/" + array[i]));
console.log('if executed');
}
}
console.log(array);
