proper-url-join

NPM version Downloads Build Status Coverage Status Dependency status Dev Dependency status

Like path.join but for a URL.

Installation

$ npm install proper-url-join

This library expects the host environment to be up-to-date or polyfilled with core-js or similar.

This library is written in ES9 and is using ES modules. You must compile the source code to support older browsers.

Motivation

There are a lot of packages that attempt to provide this functionality but they all have issues.
This package exists with the hope to do it right:

  • Consistent behavior
  • Support adding/removing leading and trailing slashes
  • Supports absolute URLs, e.g.: http//google.com
  • Supports protocol relative URLs, e.g.: //google.com
  • Supports query strings

Usage

import urlJoin from 'proper-url-join';
 
urlJoin('foo', 'bar'); // /foo/bar
urlJoin('/foo/', '/bar/'); // /foo/bar
urlJoin('foo', '', 'bar'); // /foo/bar
urlJoin('foo', undefined, 'bar'); // /foo/bar
urlJoin('foo', null, 'bar'); // /foo/bar
 
// With leading & trailing slash options
urlJoin('foo', 'bar', { leadingSlash: false }); // foo/bar
urlJoin('foo', 'bar', { trailingSlash: true }); // /foo/bar/
urlJoin('foo', 'bar', { leadingSlash: false, trailingSlash: true }); // foo/bar/
 
// Absolute URLs
urlJoin('http://google.com', 'foo'); // http://google.com/foo
 
// Protocol relative URLs
urlJoin('//google.com', 'foo', { protocolRelative: true }); // //google.com/foo
 
// With query string as an url part
urlJoin('foo', 'bar?queryString'); // /foo/bar?queryString
urlJoin('foo', 'bar?queryString', { trailingSlash: true }); // /foo/bar/?queryString
 
// With query string as an object
urlJoin('foo', { query: { biz: 'buz', foo: 'bar' } }); // /foo?biz=buz&foo=bar
 
// With both query string as an url part and an object
urlJoin('foo', 'bar?queryString', { query: { biz: 'buz', foo: 'bar' } }); // /foo/bar?biz=buz&foo=bar&queryString
