tiny-uri

tiny-uri is yet another Javascript library for working with URLs. It offers a fluent interface, method chaining, and sensible means of manipulating Url parts and a file size of less than 5K, gzipped.

Installation

npm install https://github.com/robhicks/tiny-uri.git

# or

yarn add https://github.com/robhicks/tiny-uri.git

Use

You can use the library in the browser or on NodeJs.

In the browser you can load dist/tiny-uri.iife.js in a script tag, or if you are using an es6 aware bundler like RollupJs, you can import it into your entry file.

In NodeJs, require it as usual.

Examples

Getting URL parts

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

console.log('scheme', uri.scheme()); // 'http'
console.log('host', uri.host()); // 'example.org'
console.log('path', uri.path.toString()); // /path/to/foo/index.html
console.log('query', uri.query.toString()); // hello=world

Manipulating URL parts

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

uri
  .scheme('https')
  .host('example.com')
  .authority('user:[e-mail]')
  .path.set('path/to/bar/index.html')
  .query.merge({q, 'foo'});

console.log('scheme', uri.scheme()); // 'https'
console.log('host', uri.host()); // 'example.com'
console.log('authority', uri.authority()) // 'user:[e-mail]'
console.log('path', uri.path.toString()); // /path/to/bar/index.html
console.log('query', uri.query.toString()); // hello=world

Manipulating paths

// remove the last segment of a path

const url = 'https://user:[e-mail]/path/to/file.xml';
const uri = new TinyUri(url);

expect(uri.path.delete().path.toString()).to.be.equal('to/file.xml');

// remove a specific segment of the the path

const url = 'https://user:[e-mail]/path/to/file.xml';
const uri = new TinyUri(url);

expect(uri.path.delete(0).path.toString()).to.be.equal('to/file.xml');

// should remove several segments of the the path
// delete accepts an array of segment locations. segment locations must be
// in ascending order and within the range of path segments

const url = 'https://user:[e-mail]/really/long/path/to/file.xml';
const uri = new TinyUri(url);

expect(uri.path.delete([0, 1, 2, 3]).path.toString()).to.be.equal('file.xml');

Manipulating query strings

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

console.log('query', uri.query.toString()); // hello=world

Setting the query string

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

uri.query.set({goodby: 'world'});

console.log('query', uri.query.toString()); // goodby=world

Clearing the query string

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

uri.query.clear();

console.log('query', uri.query.toString()); //

Adding to the query string

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

uri.query.add({goodby: 'world'});

console.log('query', uri.query.toString()); // hello=world&goodby=world

Merging the query string

import TinyUri from 'tiny-uri';

const uri = new TinyUri('http://example.org/path/to/foo/index.html?hello=world');

uri.
  query.add({goodby: 'world'})
  query.merge({hello: 'universe'})

console.log('query', uri.query.toString()); // hello=universe&goodby=world

Getting a specific query string parameter

Let's say you want to get the value of a context query string parameter

const url = 'https://user:[e-mail]/path/to/file.xml?context=foo&credentials=bar';
const uri = new TinyUri(url);
const credentials = uri.query.get('credentials');
const context = uri.query.get('context');
const hot = uri.query.get('hot');

console.log(credentials === 'bar') // true
console.log(context === 'foo') // true
console.log(hot === null) // true

Chaining Methods

You can chain Uri, Path and Query methods.

expect(uri.scheme().toString()).toBe('https');
expect(uri.host().toString()).toBe('big.example.com');
expect(uri.port().toString()).toBe('');
expect(Array.isArray(uri.path.get())).toEqual(true);
expect(uri.path.toString()).toEqual('path/to/file.xml');
expect(uri.query).toEqual(jasmine.any(Object));
expect(uri.query.add({foo: 'bar'}).query.toString()).toEqual('context=foo&credentials=bar&foo=bar');
expect(uri.query.add({foo: 'bar'}).query.merge({foo: 'bars'}).query.toString()).toEqual('context=foo&credentials=bar&foo=bars');
expect(uri.query.clear().query.add({foo: 'bar'}).query.merge({foo: 'bars'}).query.toString()).toEqual('foo=bars');
expect(uri.query.clear().query.add({foo: 'bar'}).query.merge({foo: 'bars'}).query.toString(true)).toEqual('https://user:[e-mail]/path/to/file.xml?foo=bars');

Changes

• 9.0.0 - the library hasn't changed but the build system has. This library only supports modern browsers and Node JS. Importing the library in the browser, pulls in an minified esm build. If you want to import the esm source directly, use import TinyUri from 'tiny-uri/src/TinyUri.js'. In node, you can use the default cjs or if you are using esm import TinyUri from 'tiny-uri/index.mjs'.
