es6-url-template

An ES6 URI template implementation

This is a simple URI template implementation following the RFC 6570 URI Template specification. The implementation supports all levels defined in the specification and is extensively tested.

This is a fork of url-template changed to use ES6 classes and exported as a module.

Installation

$ yarn add es6-url-template

Example

import UriTemplate from 'es6-url-template';
 
const emailUrlTemplate = new UriTemplate('/{email}/{folder}/{id}');
const emailUrl = emailUrlTemplate.expand({
  email: 'user@domain',
  folder: 'test',
  id: 42
});
 
console.log(emailUrl);
// Returns '/user@domain/test/42'

A note on error handling and reporting

The RFC states that errors in the templates could optionally be handled and reported to the user. This implementation takes a slightly different approach in that it tries to do a best effort template expansion and leaves erroneous expressions in the returned URI instead of throwing errors. So for example, the incorrect expression {unclosed will return {unclosed as output. The leaves incorrect URLs to be handled by your URL library of choice.
