404 error on heatmap.min.js when ui path is /

[maditnerd]

Got a 404 error on heatmap.min.js

settings.js

ui: { path: "/" }

Change this line to make a quick (but dirty fix)

RED.httpNode.get('/heatmap/js/*', function(req, res){
        var options = {
            root: __dirname + '/lib/',
            dotfiles: 'deny'
        };

I'll try to find a better way to make it works, when I understand a bit more how node-red works.

Hi Rémy,

Sorry for the delay!

When I was developing this node, we had a discussion about this kind of issues on the Node-RED forum.

Normally this line is in comment in the settings.js file:

// If you installed the optional node-red-dashboard you can set it's path
// relative to httpRoot
//ui: { path: "ui" },

But users can uncomment it, and change the path (which I need to use in my node!). Since you have uncommented it and set it to /, it indeed won't work (since I end up with 3 slashes in sequence ///heatmap/js/*)

Just out of curiosity: is there any reason why your path contains only / ?

I will try to create a fix this week. Would be nice if you could test it ...

Kind regards,
Bart

Hi Rémy (@maditnerd),

I have fixed this on Github.
You can install this version from Github directly (in your Node-RED folder):

npm install bartbutenaers/node-red-contrib-ui-heatmap

Would be nice if you could test whether it works now.
If it is OK, I will publish it on NPM.

Thanks!
Bart
