Is there a way to set the html <title> tag for dynamic routes?

[brianmercer]

Dynamic routes in Vitepress are amazing and I'm using them with csv and yaml data and they're working great.

My only problem is being unable to set the html <title>.

I can use $params in the md file content or script, but I can't use them in frontmatter. Is it possible to change page data from within the md? Can I use some code in the transformHead of the config.js?

Thanks.

OK, this seems to work after adding a title param.

// config.js

async transformPageData(pageData, { siteConfig }) {
    if (!pageData.title && pageData.params.title) {
      pageData.title = pageData.params.title
    }
},
