Best Practices about TypoScript

Emerging Best Practices about TypoScript
Why TypoScript?
http://www.sxc.hu/browse.phtml?f=view&id=956017 TypoScript as View Coordinator
Extensibility Planned Extensibility Unplanned Extensibility Supported during updates Own Risk
Planned Extensibility prototype(TYPO3.Neos:ContentCase) < prototype(TYPO3.TypoScript:Case) { default { @position =
'end' condition = TRUE type = ${q(node).property('_nodeType.name')} } }
Unplanned Extensibility # custom TypoScript prototype(TYPO3.Neos.NodeTypes:Image)
[email protected]
= false
# custom TypoScript prototype(TYPO3.Neos.NodeTypes:Image)
[email protected]
= false # Default definition of
Image TS Object prototype(TYPO3.Neos.NodeTypes:Image) { ...
[email protected]
= TYPO3.Neos:ConvertUris { forceConversion = true } } Dependency Ordering crucial!
Dependency Ordering crucial! TYPO3.Neos.NodeTypes My.Site # composer.json { "require": {
"typo3/neos-nodetypes": "*" } }
cat Configuration/PackageStates.php | grep composerName
None
Files and Folder Structure
• one TypoScript object per file • subfolders according to
your domain
Embrace TypoScript Prototypes
prototype(Acme:Slideshow) < prototype(TYPO3.Neos:Content) { .... } # Instantiation mySlideshow =
Acme:Slideshow
class Slideshow extends Content { } $mySlideshow = new Slideshow();
Explicit Names!
TypoScript prototypes for page objects page = Page { ....
} Old # COPY (bad!) specialPage < page { .... } root.special { condition = ${....} renderPath = '/specialPage' } prototype(Site:MyObject) < prototype(Page) { .... } page = Site:MyObject Recommended prototype(Site:Special) < prototype(Site:MyObject) { .... } root.special { condition = ${....} type = 'Site:Special' }
Composition vs Inheritance
MyTextWithImage MySpecialText Inheritance MyImage MyText
MyTextWithImage Composition MyImage MyText
Try to use composition!
How? prototype(MyTextWithImage) < prototype(TYPO3.Neos:Content) { image = MyImage { image
= ${q(node).property('image')} } ... same for text element }
One Content, Multiple Output Formats
prototype(TYPO3.Neos:ContentCase) < prototype(TYPO3.TypoScript:Case) { default { @position = 'end' condition
= TRUE type = ${q(node).property('_nodeType.name')} } }
prototype(Flowpack.SearchPlugin:SingleResult) < prototype(TYPO3.TypoScript:Case) { default { condition = Flowpack.SearchPlugin:CanRender {
type = ${node.nodeType.name + 'SearchResult'} } type = ${node.nodeType.name + 'SearchResult'} } fallback { condition = TRUE type = 'TYPO3.Neos:DocumentSearchResult' } } Product Product ProductSearchResult
Fluid vs TypoScript
TypoScript Fluid rendering controller extensible declarative no loops simple templates
imperative
<f:for each="{items}" as="item"> <li{ts:render(path:'{item.state}.attributes', context: {item: item}) -> f:format.raw()}> <neos:link.node
node="{item.node}">{item.label}</neos:link.node> <f:if condition="{item.subItems}"> <ul> <f:render section="itemsList" arguments="{items: item.subItems}" /> </ul> </f:if> </li> </f:for> Fine to use e.g. for menus!

The Content Cache

prototype(Page) { @cache { mode = 'cached' } }

Page Menu ContentCollection Text Plugin Image cached embed embed embed

Page Menu ContentCollection Text Plugin Image cached embed embed embed
uncached embed always rendered dynamically What is currently being rendered? What is in the (TypoScript) context?
What is currently being rendered? What is in the (TypoScript)
context? prototype(Page) { @cache { mode = 'uncached' context { 1 = 'node' 2 = 'documentNode' } } }
cached embedded part of outer cached element store in cache
uncached render dynamically
Basic Idea of caching Calculate Cache Entry Identifier Does Entry
Identifier Exist In Cache? expensive calculation (such as rendering a page) Page Cache Record store in cache e.g. URL
Configuring the Entry Identifier prototype(Page) { @cache { mode =
'cached' entryIdentifier { // parts of the entry identifier node = ${node} editPreviewMode = ${node.context.currentRenderingMode.name} } } }
Configuring the Entry Identifier prototype(Page) { @cache { mode =
'cached' entryIdentifier { // parts of the entry identifier fixedIdentifier = 'Hello World' } } }
Done!
There are only two hard things in Computer Science: cache
invalidation and naming things. -- Phil Karlton
Not Quite!
Core Question When should the cache be flushed?
When should the cache be flushed? Page Cache Record Everything
Node_A.B Everything Node_A.B DescendantOf_A NodeType_X
Confused?
Neos has sane defaults!
