relative path for static content (windows)

[DoNcK]

Hi there,

I have one machine running Node-RED on Windows. When it starts up, it displays the following :

15 Nov 14:21:56 - [info] Node-RED version: v0.17.5
15 Nov 14:21:56 - [info] Node.js  version: v4.4.2
15 Nov 14:21:56 - [info] Windows_NT 10.0.15063 x64 LE
...
15 Nov 14:21:58 - [info] User directory : \Users\donck\.node-red

So I thought I could create a "static" directory under "\Users\donck\.node-red" and edit my settings.js to serve static files

At first I used:

httpStatic: 'C:\\Users\\donck\\.node-red\\static',

That worked, but I didnt like that it was dependent from my OS and username so I wanted to use a relative path:

httpStatic: 'static',
or
httpStatic: './static',

But that does NOT work


I ended up using:

var path = require("path"); // <--- prepend this line to settings.js
httpStatic: path.join(process.env.HOMEPATH,".node-red","static"),

(path.join returns "\Users\donck\.node-red\static")


Is there a simpler way to use a relative path for static stuff that would also work on Windows machines ?


Best regards

The only alternative is, if you want it relative to the settings file without making any assumptions about where the settings file is, you can do:

   httpStatic: path.join(__dirname,"static")

Exactly what I needed, thanks Nick !

if you are wanting to get easy access to msg's from/to Node-RED to go with your static served files, you can also use node-red-contrib-uibuilder. Adding a uibuilder node creates a folder for you and gives you access to a websocket connection specific for that folder and any sub-folders.
