从 Github 文件夹下载最新文件

Question

how would I download the latest file that is uploaded to some Github repo in a particular folder? I am using Node.js with cron job to download the file, but I need to get the fresh file every day.

This is the repo if anyone is interested: https://github.com/CSSEGISandData/COVID-19

Previous day's reports are published every day, so get the latest file using the date.

 function getDate() { const yesterday = new Date(); yesterday.setDate(yesterday.getDate() - 1); let dd = yesterday.getDate(); let mm = yesterday.getMonth() + 1; const yyyy = yesterday.getFullYear(); if (dd < 10) { dd = '0' + dd; } if (mm < 10) { mm = '0' + mm; } return `${mm}-${dd}-${yyyy}` } const baseUrl = 'https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/'; function getLatestDownloadUrl() { return `${baseUrl}${getDate()}.csv`; } console.log(getLatestDownloadUrl());
