vue-lumino

An example project showing one way to integrate Vue.js and Lumino (née PhosphorJS).

Lumino “is a library for building interactive web applications”. It is used by JupyterLab to create the top menu bar, widgets with close/maximize buttons, and other components that allow users to create web applications.

Based on work done for Cylc UI.

Installation

# npm
npm install @tupilabs/vue-lumino

# yarn
yarn add @tupilabs/vue-lumino

Usage

You will have to import the Lumino component, and its stylesheet (or have a look at it and choose how to better customize it).

vue-lumino will install JupyterLab Lumino for you, if that's not in your dependency tree already. But you will still need to import the Lumino stylesheet as well in your component or sass or similar code.

The diff below is probably the easiest way to show how to use the component. It was created using vue create to create a new project using its default values. Then a version of the library was installed locally, and with the diff applied the component is ready to be used.

Custom tab title

By default, the component uses the Vue Component name as the tab title. So if the component is defined as below.

export default {
  name: 'VueComponentName'
}

It means that the tab title of the component will use the title "VueComponentName".

Alternatively, it is possible to define a prop in the Lumino component to be used for the tab title. The default value of that prop is "name".

<Lumino
  ref="lumino"
  v-on:lumino:deleted="onWidgetDeletedEvent"
  v-on:lumino:activated="onWidgetActivatedEvent"
  tab-title-prop="displayName"
>
</Lumino>

The prop MAY be present in each component rendered by the Lumino component. If the component does not define the prop, then the Lumino component will use the default value, i.e. the component name.

<Lumino
  ref="lumino"
  v-on:lumino:deleted="onWidgetDeletedEvent"
  v-on:lumino:activated="onWidgetActivatedEvent"
  tab-title-prop="displayName"
>
  <!-- HelloWorld tab titles will display TAB-HW-${id} -->
  <HelloWorld
    v-for="id of this.helloWorldWidgets"
    :key="id"
    :id="id"
    :ref="id"
    :display-name="`TAB-HW-${id}`"
  ></HelloWorld>
  <!-- ColoredCircle tab titles will display ${ColoredCircle.name}, IOW, `ColoredCircle` -->
  <ColoredCircle
    v-for="id of this.coloredCircleWidgets"
    :key="id"
    :id="id"
    :ref="id"
    :color="'red'"
  ></ColoredCircle>
</Lumino>

This is specially useful if you want to display a component is wrapped by another component. A common example of this use case, is using a loader component such as Vuetify Skeleton Loader.
