Readme
this is an improved fork of html-webpack-inline-svg-plugin
.
yarn add webpack-html-plugin-svg-inline
The differences:
- webpack-html-plugin-svg-inline will transfer all the props, except inline and src to the inlined node.
- webpack-html-plugin-svg-inline will work with webpack-dev-server, ie during developement, as long the original plugin will work only for production builds.
Inline SVG extension for the HTML Webpack Plugin
Convert .svg files into inline SVG tags within the output html of templates parsed by html-webpack-plugin.
By inlining SVGs you can combine them with techniques such as: Icon System with SVG Sprites.
As of version 1.0.0 this plugin processes SVG files after all template and image files have been written to their corresponding output directory. This allows it to work alongside loaders, after webpack resolves all file locations.
Please note: to use aliases you will need to install loaders to resolve your svg paths and parse the templates html. More info is provided below: Getting to your SVGs.
The plugin relies on svgo to optimise SVGs. You can configure it's settings, check config for more details.
Installation
Install the plugin with npm:
$ npm install --save-dev webpack-html-plugin-svg-inline
or yarn:
$ yarn add webpack-html-plugin-svg-inline --dev
Usage
Require the plugin in your webpack config:
const HtmlWebpackInlineSVGPlugin = require('webpack-html-plugin-svg-inline');
Add the plugin to your webpack config as follows:
plugins: [
new HtmlWebpackPlugin(),
new HtmlWebpackInlineSVGPlugin()
]
Add img
tags with inline
attribute and .svg
file as src to your template/s that the html-webpack-plugin is processing (the default is index.html
).
<!-- Works: below img tag will be removed and replaced by the content of the svg in its src -->
<img inline src="images/icons.svg">
<!-- Ignored: this img will not be touched as it has no inline attribute -->
<img src="images/foo.svg">
<!-- Broken: the plugin will ignore this src as it is not an svg -->
<img inline src="images/i-will-be-ignored.png">
Getting to your SVGs
Breaking change: As of version 1.0.0 the plugin waits for webpack to resolve image locations and write them to disk. If you were using a version prior to 1.0.0 then it is likely you'll need to update the src paths to your inline SVGs to reflect this change. See below for more info.
There are two ways of working with your <img>
src attributes and this plugin.
- If you are not working with loaders to allow webpack to parse and resolve the
img
tagssrc
attributes within your html-webpack-plugin templates. Use paths that are relative to your svg images from the output location of the template that is referencing it. - Alternatively use loaders such as html-loader to parse the html templates, and file-loader or something similar, to resolve the paths of your
img
tagssrc
attributes. As the plugin works after webpack has emitted all its assets and html-webpack-plugin has output your templates, it will read the SVGs that webpack places in your output directory, and replace any inlined img tags with this content.
my-project
-- package.json
-- webpack-config.js
-- <node_modules>
-- <src>
---- index.html
---- <images>
------ icons.svg
------ foo.svg
With the above structure inlining icons.svg would look like: <img inline src="images/icons.svg">
If an alias was in place for the images directory, i.e.
'img': path.join(__dirname, 'src', 'images')
Then the svg can be inlined with: <img inline src="~img/icons.svg">
. This method would require the use of loaders on your templates as shown above in point 2.
Config
To configure SVGO (module used to optimise your SVGs), add an svgoConfig
object to your html-webpack-plugin
config:
plugins: [
new HtmlWebpackPlugin({
svgoConfig: {
removeTitle: false,
removeViewBox: true,
},
}),
new HtmlWebpackInlineSVGPlugin()
]
For a full list of the SVGO config (default) params we are using check out: svgo-config.js. The config you set is merged with our defaults, it does not replace it.
Features
- Optimises / minimizes the output SVG
- Allows for deep nested SVGs
- Supports webpack aliases for file locations
- Ignores broken tags - incase you are outputting templates for various parts of the page
- Performs no html decoding so supports language tags, i.e.
<?php echo 'foo bar'; ?>
Known Issues
- none currently
