Readme
Webpack 4 plugin to generate PHP constants from SVG sprite symbol IDs based on svg-sprite-loader output.
Package contents
- webpack plugin
- runtime generator for svg-sprite-loader
- loader to de-colorize each SVG with
fill="currentColor"
Installation
Use Yarn
yarn add --dev @wavevision/sprites-constants-generator-plugin
or npm
npm install --save-dev @wavevision/sprites-constants-generator-plugin
Note: It is highly recommended to install and include svgxuse in your bundle.
Usage
Assuming your sprites are loaded from <entry>/images/<spriteName>/<image>.svg
and emitted into your build directory as <outputPath>/images/<spriteName>.svg
, your webpack config can be:
import { basename, dirname, resolve } from 'path';
import SpritesConstantsGeneratorPlugin from '@wavevision/sprites-constants-generator-plugin';
import SVGSpriteLoaderPlugin from 'svg-sprite-loader/plugin';
const images = 'images';
const sprites = ['icons', 'pictograms'];
export default {
// configure entries and output
// ...
module: {
rules: [
{
test: /\.svg$/,
include: sprites.map(s => resolve(__dirname, 'src', images, s)),
use: [
{
loader: 'svg-sprite-loader',
options: {
extract: true,
runtimeGenerator:
SpritesConstantsGeneratorPlugin.runtimeGenerator,
spriteFilename: pathname =>
`${images}/${basename(dirname(pathname))}.svg`,
symbolId: '[folder]-[name]',
},
},
SpritesConstantsGeneratorPlugin.loader,
],
},
],
},
plugins: [
new SVGSpriteLoaderPlugin({ plainSprite: true }),
new SpritesConstantsGeneratorPlugin({
namespace: 'App\\UI\\Sprites',
output: resolve(__dirname, 'src', 'App', 'UI', 'Sprites'),
replace: sprite => [`${sprite}-`, ''],
sprites: sprites.map(s => `${images}/${s}.svg`),
}),
],
};
This will output to src/App/UI/Sprites
:
Sprites.php
containing constants with each sprite name- for every sprite a
<SpriteName>.php
containing constants with eachsymbolId
as configured insvg-sprite-loader
Plugin options
ignoreErrors?: boolean
Run generator even if there are errors in webpack compilation. This option is disabled by default.
namespace: string
PHP namespace in which the generated classes will reside.
output: string
Absolute path to directory in which the generated classes will be put.
replace?: (sprite: string) => [RegExp | string, string]
Optional sprite name replacer function. Return a tuple in which:
- the first element is a search value
- the second element is a replacement
Replaces custom parts of sprite name before it is used in generated constants.
Example
You can see in our webpack config we set symbolId: '[folder]-[name]'
and spriteFilename
to use images directory name as sprite name. For images in icons
folder, that will output icons.svg
sprite in which each symbol will have icons-<image>
ID. When generating the constants class this will result in duplicate ICONS
prefix so you will use the constant as Icons::ICONS_<image>
. If you want to omit that duplicate, use the function as shown in the example, so the result will be Icons::<image>
.
sprites: string[]
List of sprite paths relative to webpack output path.
useStaticClass?: boolean
If true
, the generated classes will use Nette\StaticClass
trait. This option is enabled by default.
useStrictTypes?: boolean
If true
, the generated classes will have strict types declared. This option is enabled by default.
