Widget

Learn the specifics of developing a Device plugin.

Create the file structure

Set up a directory structure with the following files

├── src
│   ├── static                    
│   │   ├── widget.css      
│   │   ├── widget.html 
│   │   ├── widget.js             
│   ├── view.xml
│   ├── view_widget.xml
│   ├── control.py
│   ├── function.py
│   ├── user_code.py  
├── LICENSE
├── README.md
├── manifest.toml

widget.html, widget.css and widget.js scripts

Fill those files with the content that you require and according to the table below, then save them.

File	Purpose
widget.html	Define the Widget's components layout
widget.css	Define the Widget's components style
widget.js	Define the Widget's logic as well as dynamically modification of the Widget's style.

The runtime with which widget.js runs is NodeJS 20 independently of the selected runtime. Runtime selection only affects the control, function and user_code scripts.

view.xml

For the moment given, this file is not fully implemented for Widget plugin, so it is not relevant at all for this plugin type, however it should contain dummy, albeit valid data so the plugin can be deployed, for this reason, you can use this view.xml file on your Widget plugin development as dummy file:

<form name="formName">
    <group name="ubidotsInformation">
        <group name="fieldToken">
            <label name="labelToken">Ubidots Token</label>
            <token name="token" placeholder="Select Token"/>
        </group>
    </group>
</form>

view_widget.xml

Fill this file with the contents that you require to be displayed when the user is creating the widget in the dashboard.

LICENSE and README.md

Write the contents of the README.md and LICENSE files.

manifest.toml

Fill the contents of this file. According to the widget section within the Private Plugins page, the manifest.toml should look like:

manifest_version = 2.0

[settings]
version = "1.1.1"
plugin_type = "widget_webhook"
license_name = "MIT license"
runtime = "python:3.11"
infrastructure = "aws"

[settings.webhook]
default_http_method = "POST"
allowed_http_methods =  ["POST"]

[settings.widget]
name = "Send data to device widget"

js_thirdparty_libraries = [
  "https://code.jquery.com/jquery-3.6.0.min.js",
  "https://code.jquery.com/moment-3.6.0.min.js"
]
css_thirdparty_libraries = [
  "https://code.jquery.com/jquery-3.6.0.min.css",
  "https://code.jquery.com/moment-3.6.0.min.css"
]
enable_lazy_load = true

Compressing the files

Compress the files in zip format from the root of the file structure, not the parent folder.
