codepen-cli

The live editor of CodePen is not stable for me most of the time due to the network (in China...), so I always write demos on my local machine first, then open CodePen afterwards and copy/paste into the editor.

This tool is for saving this process by doing the following steps:

1. Extract external or embedded scripts and styles from a local HTML file.
2. Open a new CodePen editor with default browser.
3. Prefill each html/js/css section and external depencencies in the editor automatically.

The rest is to click the SAVE button.

Installation

$ npm install -g @yuanchuan/codepen-cli

Example

$ codepen index.html

It can be used to preview a markdown file quickly on CodePen:

$ codepen README.md

Edit a JS file on CodePen:

$ codepen example.js

Using npx which is a package runner bundled in npm:

$ npx @yuanchuan/codepen-cli index.html

Options

keep-embedded

By default all the embedded script/style in HTML will be put into js/css sections seperatly, but they can stay with the HTML using keep-embedded option.

$ codepen index.html --keep-embedded
