Rendering A Page

This section shows how content is rendered on a page as a rough overview.

More precisely we show how to render a TYPO3.Neos:Document node, as everything which happens here works for all Document nodes, and not just for Page nodes.

First, the requested URL is resolved to a Node of type TYPO3.Neos:Document. This happens by translating the URL path to a node path, and finding the node with this path then.

The node is passed straight away to TypoScript, which is the rendering mechanism. TypoScript renders the node by traversing to sub-nodes and rendering them as well. The arguments which are passed to TypoScript are stored inside the so-called context, which contains all variables which are accessible by the TypoScript rendering engine.

Internally, TypoScript then asks Fluid to render certain snippets of the page, which can, in turn, ask TypoScript again. This can go back and forth multiple times, even recursively.

The Page TypoScript Object and -Template

The rendering of a page by default starts at a Case matcher at the TypoScript path root, which will usually select the TypoScript path page. The minimally needed TypoScript for rendering looks as follows:

page = Page
page.body.templatePath = 'resource://My.Package/Private/Templates/PageTemplate.html'

Here, the Page TypoScript object is assigned to the path page, telling the system that the TypoScript object Page is responsible for further rendering. Page expects one parameter to be set: The path of the Fluid template which is rendered inside the <body> of the resulting HTML page.

If this is an empty file, the output shows how minimal Neos impacts the generated markup:

<!DOCTYPE html>
<html version="HTML+RDFa 1.1"
    This website is powered by Neos, the next generation CMS, a free Open
    Source Enterprise Content Management System licensed under the GNU/GPL.

    Neos is based on Flow, a powerful PHP application framework licensed under the GNU/LGPL.

It becomes clear that Neos gives as much control over the markup as possible to the integrator: No body markup, no styles, only little Javascript to record the last visited page (to redirect back to it after logging in). Except for the charset meta tag nothing related to the content is output by default.

If the template is filled with the following content:


the body would contain a heading to output the title of the current page:

        <h1>My first page</h1>

Again, no added CSS classes, no wraps. Why {title} outputs the page title will be covered in detail later.

Of course the current template is still quite boring; it does not show any content or any menu. In order to change that, the Fluid template is adjusted as follows:

{namespace ts=TYPO3\TypoScript\ViewHelpers}
{ -> f:format.raw()}
{content.main -> f:format.raw()}

Placeholders for the menu and the content have been added. Because the and content.main refer to a rendered TypoScript path, the output needs to be passed through the f:format.raw() ViewHelper. The TypoScript needs to be adjusted as well:

page = Page
page.body {
        templatePath = 'resource://My.Package/Private/Templates/PageTemplate.html' = Menu
        content.main = PrimaryContent {
                nodePath = 'main'

In the above TypoScript, a TypoScript object at is defined to be of type Menu. It is exactly this TypoScript object which is rendered, by specifying its relative path inside { -> f:format.raw()}.

Furthermore, the PrimaryContent TypoScript object is used to render a TYPO3CR ContentCollection node. Through the nodePath property, the name of the TYPO3CR ContentCollection node to render is specified.

As a result, the web page now contains a menu and the contents of the main content collection.

The use of content and parts here is simply a convention, the names can be chosen freely. In the example content is used for anything that content is later placed in but parts is for anything that is not content in the sense that it will directly be edited in the content module of Neos.
