A loader for webpack which transforms files into base64 URIs.
Getting Started
To begin, you'll need to install url-loader:
$ npm install url-loader --save-dev
url-loader works like
file-loader, but can return
a DataURL if the file is smaller than a byte limit.
import img from './image.png'
// webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.(png|jpg|gif)$/i,
use: [
{
loader: 'url-loader',
options: {
limit: 8192
}
}
]
}
]
}
}
And run webpack via your preferred method.
Options
fallback
Type: String
Default: 'file-loader'
Specifies an alternative loader to use when a target file's size exceeds the
limit set in the limit option.
// webpack.config.js
{
loader: 'url-loader',
options: {
fallback: 'responsive-loader'
}
}
The fallback loader will receive the same configuration options as url-loader.
For example, to set the quality option of a responsive-loader above use:
{
loader: 'url-loader',
options: {
fallback: 'responsive-loader',
quality: 85
}
}
limit
Type: Number
Default: undefined
A Number specifying the maximum size of a file in bytes. If the file is
greater than the limit,
file-loader is used by
default and all query parameters are passed to it. Using an alternative to
file-loader is enabled via the fallback option.
The limit can be specified via loader options and defaults to no limit.
// webpack.config.js
{
loader: 'url-loader',
options: {
limit: 8192
}
}
mimetype
Type: String
Default: (file extension)
Sets the MIME type for the file to be transformed. If unspecified the file extensions will be used to lookup the MIME type.
// webpack.config.js
{
loader: 'url-loader',
options: {
mimetype: 'image/png'
}
}
