Quasar App Extension qogimage

The QOGImage App Extension allows you to seamlessly add the QOGImage component into your Quasar application. It manages the boot file file and all other configuration for you.

Currently this component converts any template to svg. Work is being done to replicate the same functionality of Nuxt-ogimage component in quasar.

Install

quasar ext add @tyrsolutions/qogimage

Quasar CLI will retrieve it from NPM and install the extension.

Uninstall

quasar ext remove qogimage

Info

The app extension will add a component QOGImage and a directive v-q-og-image to the quasar app globally. Both do the same thing, generate a dynamic svg from a vue template, but work in different ways. The component is just that, a component, while the directive allows you to specify an html tag to apply the image to.

Component QOGImage

The component uses satori and satori-html to generate an svg image of a vue component file. By adding the component to your template with QOGImage and providing attributes

:template="{imported temlate goes here}"

along with

:templateProps="{template props object}"

and

:config="{satori configuration object}"

the template provided will recieve the props, then be converted to html string. This string is then applied to a vue render function returned by the component.

Directive v-q-og-image

Similar to above, though the three component element attributes are wrapped into an object and directive can be added to most html tags with an object

{
    template: ogTemplate,
    templateProps: tempProps,
    config: config,
}

provided to it.

Usage

Quasar CLI project

Install the App Extension.

OR:

Create and register a boot file:

import Vue from 'vue'
import Plugin from '@tyrsolutions/quasar-ui-qogimage'

Vue.use(Plugin)

OR:

<template>
<QOGImage :template="{imported temlate goes here}" :templateProps="{template props object}" :config="{satori configuration object}" />
<div v-q-og-image="{ template: {imported temlate goes here}, templateProps: {template props object}, config: {satori configuration object}, }"></div>
</template>

<script>
import { Component as QOGImage, Directive } from '@tyrsolutions/quasar-ui-qogimage'
imp

export default {

  components: {
    QOGImage
  },


  directives: {
    Directive
  }

}
</script>

Vue CLI project

import Vue from 'vue'
import Plugin from '@tyrsolutions/quasar-ui-qogimage'

Vue.use(Plugin)

OR:

<template>
<QOGImage :template="{imported temlate goes here}" :templateProps="{template props object}" config: config />
<div v-q-og-image="{ template: ogTemplate, templateProps: tempProps, config: config }"></div>
</template>

<script>
import { Component as QOGImage, Directive } from '@tyrsolutions/quasar-ui-qogimage'

export default {

  components: {
    QOGImage
  },


  directives: {
    Directive
  }

}
</script>

Component & Directive inputs

Both component and directive expect 3 seperate objects:

Template

The template object, is a vue component import. Simply import the template and add it to the directive or component.

Template props

The props object expects an object of key / value pairs that will match your template props. These props then get passed to the template when rendered, before the template is converted to svg.

Config

The config requires a modified satori configuraiton object. As of right now, the only difference is the fonts attribute of the config object. Normally satori expects an array buffer of a font file, which satori requires, for generating the svg file and is part of teh svg calculations. As of right now, the data attribute of the font declaration is removed and url attribute added. The object looks something like:

{
  height: 628,
  width: 1200,
  fonts: [
    {
      name: 'Roboto',
      url: 'https://cdn.jsdelivr.net/fontsource/fonts/roboto@latest/latin-400-normal.ttf',
      weight: 400,
      style: 'normal',
    },
  ],
}

The url field will be used to fetch the font file, create an array buffer of it, and pass it to satori as a data attribute. Multiple font declarations may be used in the fonts array and each one will be converted for satori.
