Hi, is it possible to load a mustache template from file with a read node and then inject data in it by a function node? Thanks in advance! ---

Yes but it is far easier to use the template node than a function for mustache. Read the built in help for the template node. ---

I tried to do it with a template node already, but that did not work for me... unless you create a flow for every different page that is requested, but that is not what I prefer, I like 1 flow. I would like to read the requested html page containing Mustache placeholders with the read node, then put it in a template and then inject the data that is pulled out of the SQLite database by JS. Could not find any example how to do that. ---

Did you read the template node help? You can inject the mustache template in `msg.template` So load file --\> move file string to msg.template --\> move mustache data to msg.payload --\> template node --\> done ---

Yes of course I read the node help 🙂 and of course I googled a lot , Can you please have a look, because I think it not works as you suggest or I make a mistake.

Your flow is usable In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````) ````auto ``` code goes here ``` ```` You can edit and correct your post by clicking the pencil ✏ icon.
