deconf-ui-toolkit

A UI Library for building decentralised conference platforms. Designed to provide a central homepage for virtual events happening on lots of other services and platforms like YouTube, Zoom, Vimeo or Twitch.

Deconf Plugin

Clients must implement a plugin to provide logic to components. It should implement DeconfPlugin and be mounted onto Vue.prototype.$deconf You could implement it like this:

import _Vue from 'vue';
import { DeconfPlugin } from '@openlab/deconf-ui-toolkit';

class BespokeDeconfPlugin implements DeconfPlugin {
  static install(Vue: typeof _Vue) {
    Vue.prototype.$deconf = new BespokeDeconfPlugin();
  }

  // Then implement DeconfPlugin methods
}

Component dependency viewer

There is a script to generate a HTML report of the components and their dependencies. It works by parsing the special comments at the top of each component files and parsing the components { ... } section of the default export.

# cd to/this/directory

# Generate a HTML report of each component and i18n, icons, sass variables and child components
node build/dependency-page.mjs > dependencies.html
open dependencies.html

# Generate JSON output
node build/dependency-page.mjs --json > output.json

Contents

Sass Styles

It should export a sass file which you can customise the variables of like:

$primary: rebeccapurple;
$secondary: green;
$family-sans-serif: Helvetica, Avenir;
// etc

@import '~@openlab/deconf-ui-toolkit/toolkit.scss';

I18n

You provide your own I18n module when importing the toolkit which has these strings set (they are all namespaced under deconf):

You can skip strings for sections you aren't using

key

• ^1 - 1 parameter (e.g. {0})
• ^2 - 2 parameters (e.g. {0} {1})
• ^3 - 3 parameters (e.g. {0} {1} {2})
• ^4 - 4 parameters (e.g. {0} {1} {2} {3})
• ^5 - 5 parameters (e.g. {0} {1} {2} {3} {5})
• ^c - count key (e.g. apples | apple | apples) to pluralise based on a count/number

WIP, for full keys used see .storybook/locale.json

General

• deconf.general.hours - Pluralise hours (^c)
• deconf.general.minutes - Pluralise minutes (^c)
• deconf.general.seconds - Pluralise seconds (^c)

Each component to use has a doc comment like this in it. It lets you know what i18n and FontAwesome icons are required, along with what sass variables can be customized.

//
// i18n
// - n/a
//
// icons
// - n/a
//
// sass
// - n/a
//

Routes

The routes that need to be implemented are defined by Routes in src/lib/constants.ts

Scss Variables

Some components expose variables to control how they are styled and coloured. See the vue component in question for more.

All of bulma's variables are also used, in particular:

• $text-strong - for heavy text
• $text-light - for light text
• $weight-bold - to make things bold
• $size-{n} - to size text
• $block-spacing - to space elements apart
• $background - to colour the background

WIP

components are writen in a specific way:

• MaintainableCss class naming #
• Global scss (no scoped)
  • global variables with !default for overrides
  • bulma variables where available
• only default exports from .vue files
• specific import filenames where not ts/js
• VSCode "story" snippet for setting up stories
• ../lib/module for common logic in components
• ../story-lib/module for common logic in stories
• prefer verbosity in stories so they are self-enclosed
• don't use Vue.extend because it ends up with a different global vue which has different routes.

how does the bundler work?

• rollup is used to compile vue components together into dist/deconf-ui.{esm}.{js,map}
  • scss
    • it currently ignores scss output right now
    • as of rollup-plugin-vue@5 vue processes the sass internally which we can't hook into
    • build/sass-plugin
      • was originally for taking sass requests for rollup and combining into a single file. This works with rollup-plugin-vue@6 but not @5
      • it is now responsible for handling rollup sass requests and completely ignoring everything
  • types
    • I couldn't find a way to get this to output TypeScript types either
• tsc is used to generate type definitions into dist/types, not bundled
• build/pull-theme is used to read in vue files, extract the scss contents into dist/theme.scss and combine into a single file
  • this relies on having no scoped vue styles + MaintainableCss class names
  • it also allows scss variables to be exposed

other notes

• we're using vue2 which storybookjs supports (02/02/2021)
