StreamDeck EasyPI

This library is meant to simplify the communication between the Property Inspector and your plugin. By sticking to a few guidelines, the library will own setting and getting the various settings for your plugin.

• Core CSS (sdpi.css):

<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/barraider/streamdeck-easypi@latest/src/sdpi.css">

• Range Tooltips (see usage examples below):

<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/barraider/streamdeck-easypi@master/src/rangeTooltip.css">

Tutorial

Common Use-case

This section is relevant for the majority of controls. There are a few different controls (such as the CheckBox or FilePicker) that require additional steps, as indicated below.
Example1:

<input class="sdProperty" id="lastName" oninput="setSettings()">

Example2:

 <select class="sdProperty" id="refreshSeconds" oninput="setSettings()">
	<option value="1">1 Second</option>
	<option value="15">15 Seconds</option>
	<option value="30">30 Seconds</option>
</select>

There are three things needed for the library to work correctly (as demonstrated in the example above):

1. Each property must have an id field. The id must be identical to the name of the property in the payload. In the example above, the library will pass two settings, one named lastName and one named refreshSeconds. The library will also look for those names to populate the values when new data is received.

2. The property must also have a class called sdProperty. The control can have additional classes too, but this one must be there.

3. Add an oninput="setSettings()" section to the control, to ensure settings are saved as soon as a user changes input.

CheckBox

To get data to and from checkboxes add an additional class named sdCheckbox in addition to the sdProperty indicated above.

<input id="enterMode" type="checkbox" class="sdProperty sdCheckbox" oninput="setSettings()">

FilePicker

To support filepickers, as recommended in the SDK follow the following guidelines:

<input class="sdProperty sdFile" type="file" id="userImage" oninput="setSettings()">
<label class="sdpi-file-info " for="userImage1" id="userImageFilename">No file...</label>

1. On the input element, add an additional class named sdFile in addition to the sdProperty indicated above.
2. Add a label, as indicated above. Make sure the Id of the label has a Filename suffix (If the input is called userImage than the label is named userImageFilename)

Dropdown lists

EasyPI supports passing a dynamic list to be shown in a dropdown. In addition, you can choose the name of the field that will hold value selected by the user. To support dynamic dropdown lists, follow the following guidelines:

<select class="sdpi-item-value select sdProperty sdList" id="sounds" oninput="setSettings()" sdListTextProperty="soundName" sdListValueProperty="soundIndex" sdValueField="soundTitle"></select>

1. On the select element, add an additional class named sdList in addition to the sdProperty indicated above.
2. Add an attribute named sdListTextProperty which is the name of the property for each item in the list that holds the text you want to show in the dropdown
3. Add an attribute named sdListValueProperty which is the name of the property for each item in the list that holds the value you want to return when an item is selected
4. Add an attribute named sdValueField which is the name of a property in the payload which will be used to both retreive the selected value and store it back if the user chooses another option in the dropdown.

Example of how this would look on the backend side:

[JsonProperty(PropertyName = "sounds")]
public List<SoundData> Sounds { get; set; }

[JsonProperty(PropertyName = "soundTitle")]
public string SoundTitle { get; set; }

and SoundData would look like this:

class SoundData
    {
        [JsonProperty(PropertyName = "soundName")]
        public string SoundName { get; set; }

        [JsonProperty(PropertyName = "soundIndex")]
        public int SoundIndex { get; set; }
    }

HTML Elements

EasyPI supports passing HTML to be shown in the InnerHTML property of an element in the Property Inspector. To support HTML elements, follow the following guidelines:

<span class="sdHTML sdProperty sdpi-item-value" id="myHtmlElement"></span>

1. On the div/span element, add an additional class named sdHTML in addition to the sdProperty indicated above.

Events

The library currently sends out two events

websocketCreate

This event will be triggered as soon as a websocket is created with the StreamDeck. Subscribe by using:

document.addEventListener('websocketCreate', function () {
	console.log("Websocket created!");
	...
});

You can also subscribe to the websocket events as part of this event:

document.addEventListener('websocketCreate', function () {
	websocket.addEventListener('message', function (event) {
		console.log("Got message event!");
	});
});

settingsUpdated

This even will be triggered when a new payload of settings is sent from the PI to the Plugin itself. Subscribe by using:

document.addEventListener('settingsUpdated', function (event) {
    console.log("Got settingsUpdated event!");
});

Ranged Tooltip

The rangedTooltip.js library allows you to see a tooltip of the current value when modifying a range element. To use:

1. Add <script src="rangeTooltip.js"></script> and <link rel="stylesheet" href="rangeTooltip.css"> to the section
2. Create a div of type="range" and give it the sdShowTooltip class (as shown below). The example below will create a range of 1-200

<div type="range" class="sdpi-item sdShowTooltip" id="dvSpeed">
	<div class="sdpi-item-label" id="speedLabel">Speed</div>
	<div class="sdpi-item-value">
		<span class="clickable" value="1">1</span>
		<input type="range" min="1" max="200" value=100 list="numbers" data-suffix=" %" class="sdProperty" id="playSpeed" oninput="setSettings()">
		<span class="clickable" value="200">200</span>
		<datalist id="numbers">
			<option>100</option>
		</datalist>
		<label for="playSpeed" class="rangeLabel"></label>
	</div>
</div>

3. For the actual range add the class="sdProperty" and the data-suffix. You can use data-suffix to decide what to show after the number (such as %, 'ms', etc.)
4. Add the following line somewhere in your HTML file:

<div class="sdpi-info-label hidden" style="top: -1000;" value="">Tooltip</div>
