Understanding Atom/RSS Feed Generation in Hugo and Blogdown

Introduction

When creating a blog or website with Hugo and Blogdown, generating an Atom or RSS feed is often overlooked until validation errors arise. In this article, we’ll delve into the world of Atom and RSS feeds, exploring how to control their generation, particularly when it comes to relative links.

Setting Up Your Project

To start working with Atom and RSS feeds in Hugo, you need a few essential components set up:

Hugo: A fast and flexible static site generator.
Blogdown: An extension for Hugo that enables building blogs.
config.toml: The configuration file used to customize your blog.

Here’s an example of what the config.toml file might look like:

[[output.on]]
  baseURL = "https://taraskaduk.com"

In this example, we’re setting the baseURL to https://taraskaduk.com. This is crucial for generating relative links in your feed.

Understanding Relative Links

When it comes to Atom and RSS feeds, relative links can be a challenge. By default, Hugo will include relative URLs in these feeds, which might cause issues during validation.

Full Links vs. Relative URLs

In the context of Atom and RSS feeds, there are two types of URLs:

Full Links: Complete URLs that start with http:// or https://.
Relative URLs: URLs that don’t include a protocol (e.g., /post/2018-01-shiny-rate/shiny_rate/).

In Atom and RSS feeds, relative URLs are often used to represent the structure of your blog. However, these feeds need to be validated against schema.org, which requires full links.

Control Index.xml for Atom/RSS

So, how do you control the generation of index.xml and ensure that it includes full links? The answer lies in understanding the roles of different configuration parameters:

baseURL: This parameter determines the base URL for your entire site. When set correctly, it ensures that relative URLs are transformed into full links.
config.toml:

[[output.on]] baseURL = “https://taraskaduk.com”


    The `baseURL` parameter is set to `https://taraskaduk.com`, which tells Hugo that the base URL for your site is this value. When generating Atom and RSS feeds, Hugo uses this base URL to create relative URLs.

### Publish Your Website via Github and Netlify

To get accurate validation results, we recommend publishing your website on platforms like GitHub and Netlify. These services offer a more robust build process that ensures correct formatting of your feed.

Here's an example of how you can configure your `config.toml` file to use these services:

```toml
[[output.on]]
baseURL = "https://taraskaduk.com"
publish = ["/public"]

By setting the `publish` parameter, we're telling Hugo to build our site on GitHub and Netlify.

Avoid Local Builds

When building locally on your computer, be sure to run the following command before publishing:

blogdown::hugo_build()

This ensures that the correct formatting is applied to your feed during local builds.

Conclusion

Generating accurate Atom and RSS feeds with Hugo and Blogdown can seem daunting at first. However, by understanding the roles of different configuration parameters and optimizing your build process, you can ensure that your feed is validated correctly.

Appendix D.3: Full Links in Atom/RSS Feeds

When validating your Atom or RSS feed, make sure to include full links in your feed’s structure. This ensures that schema.org validation works accurately, and your feed receives positive validation scores.

To achieve this, use the baseURL parameter correctly and ensure that relative URLs are transformed into full links during the build process.

Common Issues with Relative Links

Here are some common issues you might encounter when working with relative links in Atom and RSS feeds:

Relative URLs don’t include a protocol: These can be fixed by using the baseURL parameter to create full links.
Incorrect index.xml generation: This often occurs when using local builds or incorrect configuration. Ensure that your build process is correctly configured and that you’re publishing on a platform like GitHub or Netlify.

By understanding these common issues and optimizing your build process, you can ensure that your Atom and RSS feeds are validated correctly and receive positive validation scores.
