Updating tree after deleting or creating a file? about node-directory-tree HOT 4 CLOSED

I my have a solution. I remember an application that I built a year ago where I read files from a directory outside the node servers root. I had no problems whatsoever to read new files without restarting node.js. I will do a couple of tests...

from node-directory-tree.

I did a little test by changing to a directory outside the server root. But that did not work, then I built a little function based on my own code and it works! The file list gets updated. Tested with Postman.

// test read file list!
app.get('/filelist' , function(req, res){
  var fileList = [];
  //List all files and build an array of it.
    fs.realpath(repodir + '/', function(err, path) {
      if (err) {
        console.log(err);
        return;
      }
      //console.log('Path is : ' + path);
    });
    fs.readdir(repodir + '/', function(err, files) {
      if (err) return;
    for( i in files ){
      //console.log("test" + files[i]);
      fileList.push({'name': files[i]});
    }
    // send
    res.send(JSON.stringify(fileList));
  });
});

Looks as if I have to build my own directory-tree traversal solution. I have no idea why one works and the other is not...

SOLVED!
My bad, my implementation of your modul was a bit wrong, I declared to many variables. So it would hold the the listing forever I guess.

var dirTree = require('directory-tree');
var repotree = dirTree.directoryTree(repodir); <--- this will hold the value forever...

Now I tested this:

res.json(dirTree.directoryTree(repodir));

And of course it worked.

I'm glad you figured it out! Cheers!
