Frontmatter is a term used in Hugo, a popular open-source static site generator, to refer to the metadata associated with a page or post. It is defined in the configuration file and is used to store information such as page titles, authors, dates, and tags. The frontmatter type can be set to either YAML, TOML, or JSON. This determines how the data is structured and how it can be accessed. I would like to hear from others about their experiences with frontmatter type in Hugo and what tips they may have for using it effectively.
