Import image files with rollup. Let you import images just like what you do with webpack in your React code!
yarn add --dev rollup-plugin-img
or
npm install -D rollup-plugin-img
In the rollup.config.js:
import image from 'rollup-plugin-img';
export default {
entry: 'src/index.js',
dest: 'dist/bundle.js',
plugins: [
image({
limit: 10000
})
]
};and in your React code:
import img from 'path/image.png';
...
render() {
return <img src={ img } />;
}
...You can pass an option to the image() just like above, and there are some options:
- exclude & include: Optional. like other rollup plugins. Details
- output: Required. the dest path of output image files. The first directory of dest will be handled as the base output directory(where the html file will be, usually).
- extensions: Optional. a regular expression for the extensions of image files.
- limit: Optional. the limit(byte) of the file size. A file will be transformed into base64 string when it doesn't exceeded the limit, otherwise, it will be copyed to the dest path.
- hash: Optional. a boolean value to indicate wheather to generate a hash string in file name(default false).
demo:
...
image({
output: `${distPath}/images`, // default the root
extensions: /\.(png|jpg|jpeg|gif|svg)$/, // support png|jpg|jpeg|gif|svg, and it's alse the default value
limit: 8192, // default 8192(8k)
exclude: 'node_modules/**'
})
