# ember-inline-svg

[![CI](https://github.com/minutebase/ember-inline-svg/actions/workflows/ci.yml/badge.svg)](https://github.com/minutebase/ember-inline-svg/actions/workflows/ci.yml)

Displays SVG images inline.

## Compatibility

* Ember.js v3.20 or above
* Ember CLI v3.20 or above
* Node.js v12 or above

## Installation

```bash
ember install ember-inline-svg
```

## Usage

```handlebars
{{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:

```handlebars
{{inline-svg "my-svg" class="foo"}}
```

Also, you can add/update `` by doing:

```handlebars
{{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:

```javascript
var app = new EmberApp({
svg: {
paths: [
'public/images',
'app/svgs'
]
}
});
```

### Optimizing

SVGs are optimized by [svgo](https://github.com/svg/svgo) by default.

You can configure this by setting the `svg.optimize` options:

```javascript
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:

```javascript
var app = new EmberApp({
svg: {
optimize: false
}
});
```

### Custom Plugins

SVGO [now supports](https://github.com/svg/svgo/commit/1ec50c4a13ecea4c50619cdb3bab4926f6aa53e1) custom plugins.

See [SVGO's plugins](https://github.com/svg/svgo/tree/master/plugins) for examples on what you can do.

Eg, here's how you could strip IDs from all elements:

```javascript
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](#svg-paths) 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](#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](https://github.com/minutebase/ember-inline-svg/issues/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.

1. Check the spelling.
2. Make sure that your path is without a leading slash, e.g. `foo/bar/baz.svg` vs. `/foo/bar/baz.svg`.
3. The path is always absolute and not relative to the current URL.
4. `public` is not part of the path. So use `foo.svg` instead of `/public/foo.svg`.
5. If you fiddled around with the [`svg.paths` option](#svg-paths), check the following:
- The `.svg` file you're trying to inline is a direct or indirect child of any of the directories listed in `svg.paths`.
- If the filename is something like `/public/images/foo/bar.svg` and your `svg.paths` option is set to something like `['public/images']`, you have to address the image with `foo/bar.svg`, instead of the default `images/foo/bar.svg`.
