Installation

• NPM

npm install emblem-generator-vue

• Yarn

yarn add emblem-generator-vue

Usage

Import EmblemGenerator component from node_modules and one of the following themes:

• light-theme.css
• dark-theme.css

Or you can create your own custom theme.

<template>
  <div>
    <EmblemGenerator
      :assets="assets"
      :emblemData="emblemData"
    />
  </div>
</template>  
 
<script>
import { EmblemGenerator } from 'emblem-generator-vue'
import '../node_modules/emblem-generator-vue/src/css/light-theme.css';
 
export default {
  name: 'my-component',
  components: {
    EmblemGenerator
  },
  data() {
    return {
      assets: {
        // See assets section below
      },
      emblemData: {
        // See emblemData section below
      },
    }
  }
}
 
</script>

Assets

Assets are SVGs definitions that will be used by the EmblemGenerator to generate emblems.

Its a javascript object that looks like that:

const assets = {
  defs: {}, // foregrounds
  bg_defs: {}, // backgrounds
}

You can take a look at src/customAssets.js to see how they are defined.

To use these default assets, for example, you can do this:

<script>
...
 
import assets from '../node_modules/emblem-generator-vue/src/customAssets';
 
...
 
data() {
  return {
    assets: {
      defs: assets.defs,
      bg_defs: assets.bg_defs,
    }   
  }
}
 
// Or shorthand syntaxe
data() {
  return {
    assets 
  }
}
...

Foregrounds and Backgrounds

To use custom foregrounds and backgrounds, you will need to use the AssetGenerator provided by emblem-generator module.

Add the SVG files you want to use in some-folder/backgrounds and some-folder/emblem respectively.

NOTE: Check the specifications for the SVG files in the README of emblem-generator module

Then generate the assets with this command:

node node_modules/emblem-generator/util/AssetGenerator.js some-folder some-output-folder

You'll find the generated assets in the some-output-folder directory.

EmblemData

EmblemData is an object that contains the options to generate an emblem. It contains the IDs of the selected foregrounds and backgrounds, colors definitions and flip flags.

example:

<script>
...
 
data() {
  return {
    emblemData: {
      background_id: 1,
      foreground_id: 2,
      flags: [],
      background_color: '#ff0ff0',
      foreground_primary_color: 'rgb(0, 125, 75)',
      foreground_secondary_color: 'hsl(45,100,50)',
    }   
  }
}
 
...

The foreground and background IDs are defined in the assets file.

If you pass an empty object, it will generate a random emblem.

Options

You can pass some props to EmblemGenerator to customize the usage.

Most of the props are to override the default texts:

Example:

<EmblemGenerator
  :assets="assets"
  :emblemData="emblemData"
  :size=512
  backgroundTxt="My custom text"
  foregroundTxt="My custom text"
  primaryColorTxt="My custom text"
  secondaryColorTxt="My custom text"
  flipVerticallyTxt="My custom text"
  flipHorizontallyT="My custom text"
  randomizeTxt="My custom text"
  generatingTxt="My custom text"
  :useBackground="false"
  :displayFlip="false"
  :displayGeneratingLoader="false"
/>

Events

The update-emblem-data event is triggered by EmblemGenerator when the emblem is updated with the emblemData object as payload.

Usage example:

<EmblemGenerator
  :assets="assets"
  :emblemData="emblemData"
  :size=512
  @update-emblem-data="update"
/>
 
...
 
<script>
export default {
  ...
  methods: {
    update(emblemData) {
      // do stuff
    }
  }
}
</script>

EmblemDisplayer

As we pass the emblemData object to the EmblemGenerator component, when generating the emblem, the parent will get the data of the corresponding emblem into this object.

You can then do whatever you want with this data, for example store it in a database.

Then if you want to display your emblem from this data, you can use the EmblemDisplayer component:

<template>
  <div>
    <EmblemDisplayer
      :assets="assets"
      :emblemData="emblemData"
    />
  </div>
</template>  
 
<script>
import { EmblemDisplayer } from 'emblem-generator-vue'
 
export default {
  name: 'my-component',
  components: {
    EmblemDisplayer
  },
  data() {
    return {
      assets: {
        // See assets section above
      },
      emblemData: {
        // See emblemData section above
      },
    }
  }
}
 
</script>

You can pass a size props to define the size of the displayed emblem (the emblem is a square).

To be able to display different emblems in the same page, the divs where the emblems are generate must have a different id. To achieve this, a random id is generate for the containing divs. But if you need to have a specific id (for CSS purpose or something else) you can pass a divId props.

Example:

<EmblemDisplayer
  :assets="assets"
  :emblemData="emblemData"
  :size="512"
  divId="customId" // The generated id will be "emblem-displayer-customId"
/>
