How to convert HostBuffer to String?

[albham]

Hello,

I want to modify a webpage content, loaded as a Resource, to change some word
(in HandleBars style).

So I'm trying to convert the HostBuffer returned by Resource to String so I can do: replace('{{ssid}}', ssid).

Is this possible? Is there any other better way?

Thanks, Alberto.

A HostBuffer can generally be used like an ArrayBuffer. You can convert it to a string using the TextDecoder API:

import TextDecoder from "text/decoder";

let decoder = new TextDecoder;
let text = decoder.decode(resource);

To use TextDecoder you will need to add its manifest, $MODDABLE/modules/data/text/decoder/manifest.json, to your project's manifest.json.

A lightweight solution is to use the XS API String.fromArrayBuffer:

let text = String.fromArrayBuffer(resource);

You mention "HandleBars style." It is possible to run Mustache.js in the Moddable SDK. See the Template node implementation of Node-RED MCU Edition for an example of that.
