This is a small, fast, and light sale system built with no heavy backend modules. I designed a framework that could complete the crud functions of production and also with a nice show list interface. I use Google Excel to store the goods items data, you can check the example here. The 'publish' function could let us access our table online so that we can get the content/data via filtering the HTML file. Then I store the pictures of goods on GitHub.com and use the cdn like fastened by jsDelivr. Finally, with the data and image URLs, we can build our front-end interface. I used the simple style to list the items and hosted the pages on the public service platform called Glitch.com.
If you'd like to build up your online shop, you can read the description of the system and make it by yourself immediately.
