Creating a modal

Creating a modal-widget is pretty similar to creating a flat-widget. The model should act as the detailed view of a flat-widget and can also fit the purpose of user interaction.

There are multiple implementations of modals at the creation time of this page, but the one thats considered best practice is the unit-testable version.

Creating a Line

Lets take a look at one example.

public static generateView(
    config: EdgeConfig, role: Role, translate: TranslateService)
    :OeFormlyView {

    // Total
      type: 'channel-line',
      name: translate.instant('General.TOTAL'),
      channel: '_sum/ConsumptionActivePower',

    return {
      title: translate.instant('General.grid'),
      lines: lines

Predefined fields in OeFormlyField can be used here.

For this line we use the type 'channel-line'. This represents a line, where a channel has to be subscribed. You also need to specify the converter, that uses the data coming from this channel and mutates it. A filter, which has to return a boolean, decides if the line will be shown or not.

Lines should always present one line of data visualisation. It could be consisting of a identifier and a value or just a value. The value or channel will be shown at the end of the line, the name, if provided, at the start.

This line will be looking like this:
