Global settings ‚Äč

Editable content or settings used across your app can be managed through the global doc. You can use this for many things, including configuring:

  • company information or navigation in the website footer
  • a special ID for a third-party service, such as Google Analytics
  • social media account URLs

The global doc is a special piece: it is created automatically and there can only be one. It is configured through the @apostrophecms/global piece type module.

To demonstrate, we may want to display an organizational Github URL in the website footer and a "Contact" page. We can add that to the global doc as we would on any other piece type.

// modules/@apostrophecms/global/index.js
module.exports = {
  fields: {
    add: {
      githubUrl: {
        type: 'url',
        label: 'Github organization url'
    group: {
      basics: {
        label: 'Basics',
        fields: ['githubUrl']

Once the global doc is configured with fields, it will be added to the admin bar for editing.

Templates always have direct access to the global doc as The Github URL field could be used in a template as a property of that doc:

{% extends data.outerLayout %}

{% block afterMain %}
    {% if %}
      <a href="{{ }}">Our Github organization</a>
    {% endif %}
{% endblock %}


Since the global doc is available in every template it can be tempting to add all kinds of data to it. This can eventually lead to performance problems since the whole global doc is fetched for templates on every page request. If it contains a lot of content areas and has relationships with other docs, that one request can get very large.

A basic guideline is that things should only be added to the global doc if they are used in at least 50% of pages.
