Urigami

A tiny library providing parsing and joining urls

Installation

npm install urigami

Usage

const {urlJoin, urlParse} = require('urigami')

console.log(urlJoin('http://a.com/some/url', 'aaa/ccc', 'bbb/ddd'))
// output: http://a.com/some/url/aaa/ccc/bbb/ddd/
console.log(urlJoin('http://a.com/some/url', '../../ccc'))
// output: http://a.com/ccc/
console.log(urlJoin('http://a.com', 'aaa/ccc', '/bbb/ddd'))
// output: http://a.com/bbb/ddd/ (because /bbb/ddd is absolute)

urlParse('https://some-url.com:8122/some/internal/location?lorem=ipsum&foo=bar#page-fragment')
/* returns
{
    schema: 'https',
    host: 'some-url.com',
    port: 8122,
    path: '/some/internal/location',
    params: {
        lorem: 'ipsum',
        foo: 'bar',
    },
    fragment: 'page-fragment'
}
*/

Important info about joining urls

• incoming relative url is joined to current path

urlJoin('http://a.com/some/url', 'aaa/ccc')
// returns 'http://a.com/some/url/aaa/ccc/'

• incoming absolute path rewrites current

urlJoin('http://a.com', 'aaa/ccc', '/bbb/ddd')
// returns: 'http://a.com/bbb/ddd/'

• query params are always merging

urlJoin('http://a.com/some_url?a=b', 'internal?c=d')
// returns: 'http://a.com/some_url/internal/?a=b&c=d'

• every incoming fragment rewrites current fragment

urlJoin('http://a.com/some_url?a=b#existing-fragment', 'internal_path#new-fragment')
// returns: 'http://a.com/some_url/internal_path/?a=b#new-fragment'
