ember-inline-svg
Displays SVG images inline.
Compatibility
- Ember.js v3.4 or above
- Ember CLI v2.13 or above
- Node.js v8 or above
Installation
ember install ember-inline-svg
Usage
{{inline-svg "path/to/file"}}
This will display the SVG found at /public/path/to/file.svg
(see below on how to change this).
You can specify a class for the element like so:
{{inline-svg "my-svg" class="foo"}}
Also, you can add/update <title></title>
by doing:
{{inline-svg 'mySVG' title="myTitle"}}
{{inline-svg 'mySVG' class="myClass" title="myTitle"}}
Configuring
SVG Paths
By default the addon expects to find your SVG images at /public/
, but you can change this
by setting the svg.paths
option in your application's ember-cli-build.js like so:
var app = new EmberApp({
svg: {
paths: [
'public/images',
'app/svgs'
]
}
});
Optimizing
SVGs are optimized by svgo by default.
You can configure this by setting the svg.optimize
options:
var app = new EmberApp({
svg: {
optimize: {
plugins: [
{ removeDoctype: false },
{ removeTitle: true },
{ removeDesc: true }
]
}
}
});
Please bear in mind that but default we are stripping title
from any svg with removeTitle: true
, you can
disable it with removeTitle: false
or alternatively, you can disable every optimization by doing:
var app = new EmberApp({
svg: {
optimize: false
}
});
Custom Plugins
SVGO now supports custom plugins.
See SVGO's plugins for examples on what you can do.
Eg, here's how you could strip IDs from all elements:
var app = new EmberApp({
svg: {
optimize: {
plugins: [
{
myCustomPlugin: {
type: "perItem",
fn: function(item) {
item.eachAttr(function(attr) {
if (attr.name === 'id') {
item.removeAttr('id')
}
});
}
}
}
]
}
}
});
Troubleshooting
Atrociously slow build times >:[
Longer build times have two main causes:
- huge
.svg
files - lots of
.svg
files
You can easily run into this when using SVG fonts. By default ember-inline-svg
processes all .svg
files contained in the /public
directory. If your fonts live somewhere inside that directory, e.g. /public/fonts
, these files will be processed, although you will never use them (as inline SVGs).
A quick and easy fix is changing the svg.paths
option in the configuration. Just explicitly list all directories with images that you want processed by ember-inline-svg
.
If the longer build time is not caused by SVG fonts, but by actual SVG images that you actually need, you can turn off the optimization as a whole or individual plugins to remove or diminish another time-consuming build step.
Currently the caching does not work as expected. The bug is tracked in issue #15. We are positive, that fixing this bug will speed up the builds.
No SVG found / The Handlebars template is not rendered
If you switch to a route that contains an {{inline-svg}}
helper and nothing is displayed, like really nothing, then this is caused by a failed assertion. Open the Dev Tools and you will see something like this:
Error: Assertion Failed: No SVG found for foo/bar/baz.svg
This happens, when you try to inline a non-exisent or wrongly addressed .svg
file.
- Check the spelling.
- Make sure that your path is without a leading slash, e.g.
foo/bar/baz.svg
vs./foo/bar/baz.svg
. - The path is always absolute and not relative to the current URL.
public
is not part of the path. So usefoo.svg
instead of/public/foo.svg
.- If you fiddled around with the
svg.paths
option, check the following:
- The
.svg
file you're trying to inline is a direct or indirect child of any of the directories listed insvg.paths
. - If the filename is something like
/public/images/foo/bar.svg
and yoursvg.paths
option is set to something like['public/images']
, you have to address the image withfoo/bar.svg
, instead of the defaultimages/foo/bar.svg
.
