The best way to embed SVG images into your Ember application

Features

  • a visual workflow to find and use your assets the fastest way possible
  • automatic SVG optimization (it can cut file size by half or more)
  • work out of the box (no configuration needed)
  • an easy to use helper {{svg-jar "asset-name"}}
  • support for both inline and symbol embedding methods

Why does this matter?

I know why. Just show me how to get started.

Switching from Font Awesome to SVG will save you 80 Kb or even more:

  • original Font Awesome is about 149 KB as TTF and 88.3 KB as WOFF
  • it includes 634 icons and you need just some of them usually
  • 20 Font Awesome icons in SVGJar will be about 4.3 KB (you save 84 KB or 145 KB as TTF)
  • 50 Font Awesome icons in SVGJar will be about 9 KB

You can get Font Awesome icons as individual SVG files from font-awesome-svg:

git clone git@github.com:ivanvotti/font-awesome-svg.git

SVG vs icon fonts

If you can go IE 9+ and Android 3+, SVG is a better solution than icon fonts. Also if your images are multi-coloured or involved in animation, you actually have to use SVG.

Installation

$ ember install ember-svg-jar

Start in 4 easy steps

  • Put some SVG files to any place in your project's public directory (e.g. get some from font-awesome-svg)
  • Run the development server and open this link with Chrome: http://localhost:4200/ember-svg-jar/index.html
  • Select any SVG there and press Enter to copy it to the clipboard.
  • Paste it into any template and see it rendered in your browser.

Usage

Drag and drop SVG images to your project's public directory and copy & paste them from the assets viewer to your templates.

The viewer is available at: http://localhost:4200/ember-svg-jar/index.html

Assets from Node modules

By default ember-svg-jar looks for SVGs in the public directory. To get SVGs from node_modules packages or any other directory you will need to add them to ember-cli-build.js like this:

  var app = new EmberApp(defaults, {
    svgJar: {
      sourceDirs: [
        'node_modules/material-design-icons/file/svg/design',
        'node_modules/material-design-icons/action/svg/design',
        'public/images/icons'
      ]
    }
  });

Helper

Use the svg-jar helper to embed SVG images to your application's templates:

{{svg-jar "my-cool-icon" class="icon" width="24px"}}

The helper takes an asset ID and optional attributes that will be added to the created SVG element. The example above will create an SVG like this:

<svg class="icon" width="24px">...</svg>

Configuration

Note: Ember SVGJar should be useful without any configuration. But it wants to be very configurable when it's time to adjust it for your needs.

Compatibility

The addon is compatible with Ember 1.10.1 and beyond.

FAQ

Q: Will the asset viewer affect my production build size?
A: No, it won't at all. The asset viewer is included in development mode only.

Q: Can it find SVG icons outside of the public directory, e.g. from node_modules?
A: Yes, it can import SVGs from any directory defined in the sourceDirs array.
