How to generate an RSS feed for your blog with JavaScript and Netlify functions

The author built an RSS feed for their microblog using Node.js and Netlify functions, despite having no front-end frameworks, as part of their "no-frameworks" philosophy. They used Contentful's GraphQL API to fetch data, built an XML string, created an XML document, and sent it to the browser with a "text/xml" content-type. The author tested their function by pushing code to their repository, deploying to Netlify, and accessing the URL of their function in the browser or using the Netlify CLI. They also added auto-discovery metadata to their index.html file to enable readers to subscribe via RSS feeders. The author concludes that RSS is a valuable tool for enabling people to access content in whatever way they choose.
