url-loader
Original address:https://webpack.js.org/loaders/url-loader/
webpack version: 2.2.1
Converting image files to base64 encoding and loading into the browser can reduce the number of http requests, but increases the size of the js or html files. If the image is more reusable in the project, each reference will generate a base64 encoding, resulting in The redundancy of the code. Files loaded into the browser via http request can be cached locally. When the reusability of the image in the project is high, the convenience of caching is increased for the access of the image, and the next access is faster. Therefore, we must balance considerations.
Install
cnpm install --save-dev url-loader
Usage
The url loader works similarly to the file loader, but if the file is smaller than the byte limit, it can return Data Url.
You need to specify the limit with a query parameter. The default is no limit.
If the file is larger than limit (in bytes), webpack will use file-loader to process the file, and all query parameters will be passed to file-loader.
note：
- You do not need to install file-loader when using url-loader.
- The query parameter in the file-loader is also valid in the url-loader setting.
require("url-loader?limit=10000!./file.png");
// => DataUrl if "file.png" is smaller than 10kb
require("url-loader?mimetype=image/png!./file.png");
// => Specify mimetype for the file (Otherwise it's inferred from extension.)
require("url-loader?prefix=img/!./file.png");
// => Parameters for the file-loader are valid too
// They are passed to the file-loader if used.
