In this project, I did the following steps: 1- Build a front-end web page with Angular and go to https://data.taipei/ to retrieve "今日氣象資訊" data, and organize and display the data to users by: ● Using a Table to display the original data. ● Adding filter, search, sort features for the Table. 2- Build a back-end system with Node.js, Express.js, MongoDB and go to the same link https://data.taipei/ to retrieve "今日氣象資訊" data, and store it in a database. This back-end system also provides a public API interface, so that other parties can read the contents of the database through the API. Update the data in the database every hour. 3- When the original API link is not available, use the data in the database as a backup for the Table.
