A smaller Universal WHATWG
URL
, for Browserify/etc.
The universal-url package bundles to 392kB (99kB gzipped). This package exists to compile the same to a smaller file size via custom optimizations.
This package is not meant to be required/imported directly. It should be added to your browser build process as an alias.
Node.js >= 6
is required. To install, type this at the command line:
npm install universal-url-lite
Usage:
"browser": {
"universal-url": "universal-url-lite"
}
File size optimizations have been made, particularly the near-complete exclusion of the TR46 implementation. Functionality is essentially the same as the universal-url
package, with the exception of IDNA validation and normalization. If a URL contains a hostname with any of the ~4500 Unicode characters requiring a specific casefold, comparison will produce false negatives. Consider this example:
const url1 = new URL('http://ㅼㅼㅼ/');
const url2 = new URL('http://ᄯᄯᄯ/');
console.log(url1.hostname === url2.hostname);
//-> false -- which is incorrect
With invalid IDNAs passing through without error, you will instead need to rely on errors produced by XMLHttpRequest
/fetch
to know that such URLs are unreachable.
Note: You will need to exclude this browser shim from bundle parsing since it has already been compiled. Browserify has the --noparse
CLI option and Webpack has the noParse
package.json key.
browserify in.js --outfile=out.js --noparse='/project/node_modules/universal-url-lite/lite.js'
This actually includes no shim at all for browser builds. Only the latest browsers will be supported.
Usage:
"browser": {
"universal-url": "universal-url-lite/native"
}
