From dfc9997c26ae803213d0267fe981d6cde45d644e Mon Sep 17 00:00:00 2001 From: Matthew Phillips Date: Wed, 5 Sep 2018 22:46:00 -0400 Subject: [PATCH 1/2] Adds an ES module This adds an ES module, page.mjs that exports the `page` object as the default export. Can be used like so: ```js import page from '//unpkg.com/page/page.mjs'; page('/', show); ``` Eventually we might want to change the README to show this as the primary usage.
