ctx.meta(key, value?)

A per-request key/value store for page metadata (title, description). Set with two arguments, read with one. In templates it's also available as meta.

<!-- a page -->
<% meta('title', data.product.getString('name')) %>
<% meta('description', data.product.getString('summary')) %>

<!-- +layout.ejs -->
<title><%= meta('title') || 'My shop' %></title>
<meta name="description" content="<%= meta('description') %>">

Layouts render after the page, so they see what the page set.

Front matter

In a .md page, each top-level key of the YAML front matter is passed to ctx.meta(key, value):

---
title: About us
description: Who we are
---
