How to change node-red page title

How can I change node-red page title?

I have seen an issue on node-red's github page about this. But I could not understand which file I need to make changes.

Here is that issue on github.

Same thing on node-red web site configuration section.

Which file do need to change? Do I need to install a node for editing theme?

Solution

From the documentation you link to:

When run as a standalone application, these properties are read from the settings.js file. The location of this file is determined in the order:

set using the --settings|-s command-line argument

in the user directory if it was specified by the --userDir|-u command-line argument

in the default user directory: $HOME/.node-red/settings.js

in the node-red install directory

When you run node-red it logs the path to the exact settings file it is using, for example:

5 Feb 14:59:12 - [info] Settings file  : /Users/nol/.node-red/settings.js

Within that file you'll see the default set of settings within a block that starts:

module.exports = {


}

You need to add the editorTheme property within that block - remember to keep it a valid javascript statement, so you'll need a comma (,) between this and the previous setting.

For example:

module.exports = {
    ... all your existing settings ...

    editorTheme: {
        page: {
            title: "My own Node-RED title"
        }
    }
}

Once you've edited the file, restart Node-RED to pickup the changes.
