Page-based routing can now be configured within a site
configuration to add so-called "route enhancers" which
allow to add more placeholders to a route for a page.

There are three Enhancers that TYPO3 now ships with:
- SimpleEnhancer
- PluginEnhancer
- ExtbasePluginEnhancer

It is also possible to add custom enhancers by third-
party extensions.

Each placeholder within an enhancer can receive a
so-called "Aspect", usually used for mapping speaking
values instead of IDs, or month-names in an archive
link, and "modifiers" to modify a placeholder.

The simple enhancer transfers a link parameter,
previously maybe used to add a `&product=123`,
which will now result into `/product/123` for a
page. PluginEnhancer adds a namespace, common
for simple plugins or Pi-Based plugins, and
the ExtbasePluginEnhancer adds logic for multiple
route variants to be added, depending on the
controller/action combinations.

Aspects are processors / modifiers / mappers to
transfer a placeholder value back & forth to
make each placeholder value more "speaking".

TYPO3 Core ships with the following aspects:
* LocaleModifier (for localized path segments)
* StaticValueMapper (for path segments with a static list)
* StaticRangeMapper (for pagination)
* PersistedAliasMapper (for slug fields)
* PersistedPatternMapper (for database records without slug fields)

Routing now returns a so-called "PageArguments" object
which is then used for evaluating site-based URL
handling and the cHash calculation.

It is highly discouraged to access _GET or _POST
variables within any kind of code now, instead
the PSR-7 request object should be used as much
as possible.

+===============================================
+Feature: #86365 - Routing Enhancers and Aspects
+===============================================
+
+See :issue:`86365`
+
+Description
+===========
+
+Page-based routing is now flexible by adding enhancers to Routes that are generated or resolved with parameters, which
+were previously appended as GET parameters.
+
+An enhancer creates variants of a specific page-base route for a specific purpose (e.g. one plugin, one Extbase plugin)
+and enhance the existing route path which can contain flexible values, so-called "placeholders".
+
+On top, aspects can be registered to a specific enhancer to modify a specific placeholder, like static speaking names
+within the route path, or dynamically generated.
+
+To give you an overview of what the distinction are, we take a regular page which is available under
+
+`https://www.example.com/path-to/my-page`
+
+to access the Page with ID 13.
+
+Enhancers are ways to extend this route with placeholders on top of this specific route to a page.
+
+`https://www.example.com/path-to/my-page/products/{product-name}`
+
+The suffix `/products/{product-name}` to the base route of the page is added by an enhancer. The placeholder variable
+which is added by the curly braces can then be statically or dynamically resolved or built by an Aspect or more
+commonly known a Mapper.
+
+Enhancers and aspects are activated and configured in a site configuration, currently possible by modifying the
+site's `config.yml` and adding the `routeEnhancers` section manually, as there is no UI for doing this. See
+examples below.
+
+It is possible to use the same enhancers multiple times with different configurations, however, be aware that
+it is not possible to combine multiple variants / enhancers that match multiple configurations. @todo: How to describe this the best?
+
+However, custom enhancers can be built to overcome special use cases where e.g. two plugins with multiple parameters
+each could be configured. Otherwise, the first variant that matches the URL parameters is used for generation and
+resolving.
+
+Enhancers
+^^^^^^^^^
+
+TYPO3 comes with the following enhancers out of the box:
+
+- Simple Enhancer (enhancer type "Simple")
+- Plugin Enhancer (enhancer type "Plugin")
+- Extbase Plugin Enhancer (enhancer type "Extbase")
+
+Custom enhancers can be registered by adding an entry to an extensions` :php:`ext_localconf.php`.
+
+:php:`$GLOBALS['TYPO3_CONF_VARS']['SYS']['routing']['CustomPlugin'] = \MyVendor\MyPackage\Routing\CustomEnhancer::class;`
+
+Within a configuration, an enhancer always evaluates the following properties:
+- `type` - the short name of the enhancer as registered within `$TYPO3_CONF_VARS`. This is mandatory.
+- `limitToPages` - an array of page IDs where this enhancer should be called. This is optional. This property (array)
+  evaluates to only trigger an enhancers for specific pages. In case of special plugin pages it is
+  useful to only enhance pages with IDs, to speed up performance for building page routes of all other pages.
+
+Simple Enhancer
+---------------
+
+The Simple Enhancer works with various route arguments to map them to a argument to be used later-on.
+
+   `index.php?id=13&category=241&tag=Benni`
+
+
+`https://www.example.com/path-to/my-page/241/Benni`
+
+The configuration looks like this:
+
+:yaml:
+    routeEnhancers:
+      # Unique name for the enhancers, used internally for referencing
+      CategoryListing:
+        type: Simple
+        limitToPages: [13]
+        routePath: '/show-by-category/{category_id}/{tag}'
+        defaults:
+          tag: ''
+          requirements:
+            category_id: '[0-9]{1..3}'
+            tag: '^[a-zA-Z0-9].*$'
+          _arguments:
+            category_id: 'category'
+
+The configuration option `routePath` defines the static keyword (previously known to some as "postVarSets" keyword for
+some TYPO3 folks), and the available placeholders.
+
+The `requirements` section exactly specifies what kind of parameter should be added to that route as regular expression.
+This way, it is configurable to only allow integer values for e.g. pagination. If the requirements are too loose, a
+URL signature parameter ("cHash") is added to the end of the URL which cannot be removed.
+
+The `defaults` section defines which URL parameters are optional. If the parameters are omitted on generation, they
+can receive a default value, and do not need a placeholder - it is also possible to add them at the very end of the
+`routePath`.
+
+The `_arguments` section defines what Route Parameters should be available to the system. In this example, the
+placeholder is called `category_id` but the URL generation receives the argument `category`, so this is mapped to
+this very name.
+
+An enhancer is only there to replace a set of placeholders and fill in URL parameter or resolve them properly
+later-on, but not to substitute the values with aliases, this can be achieved by Aspects.
+
+
+Plugin Enhancer
+---------------
+
+The Plugin Enhancer works with plugins on a page that are commonly known as `Pi-Based Plugins`, where previously
+the following GET/POST variables were used:
+
+   `index.php?id=13&tx_felogin_pi1[forgot]=1&&tx_felogin_pi1[user]=82&tx_felogin_pi1[hash]=ABCDEFGHIJKLMNOPQRSTUVWXYZ012345`
+
+The base for the plugin enhancer is to configure a so-called "namespace", in this case `tx_felogin_pi1` - the plugin's
+namespace.
+
+The Plugin Enhancer explicitly sets exactly one additional variant for a specific use-case. In case of Frontend Login,
+we would need to set up multiple configurations of Plugin Enhancer for forgot and recover passwords.
+
+:yaml:
+
+   routeEnhancers:
+     ForgotPassword:
+       type: Plugin
+       limitToPages: [13]
+       routePath: '/forgot-password/{user}/{hash}'
+       namespace: 'tx_felogin_pi1'
+       defaults:
+         forgot: "1"
+       requirements:
+         user: '[0-9]{1..3}'
+         hash: '^[a-zA-Z0-9]{32}$'
+
+
+If a URL is generated with the given parameters to link to a page, the result will look like this:
+
+   `https://www.example.com/path-to/my-page/forgot-password/82/ABCDEFGHIJKLMNOPQRSTUVWXYZ012345`
+
+If the input given to generate the URL does not meet the requirements, the route enhancer does not offer the
+variant and the parameters are added to the URL as regular query parameters. If e.g. the user parameter would be more
+than three characters, or non-numeric, this enhancer would not match anymore.
+
+As you see, the Plugin Enhancer is used to specify placeholders and requirements, with a given namespace.
+
+If you want to replace the user ID (in this example "82") with the username, you would need an aspect that can be
+registered within any enhancer, but see below for details on Aspects.
+
+
+Extbase Plugin Enhancer
+-----------------------
+
+When creating extbase plugins, it is very common to have multiple controller/action combinations. The Extbase Plugin
+Enhancer is therefore an extension to the regular Plugin Enhancer, except for the functionality that multiple variants
+are generated, typically built on the amount of controller/action pairs.
+
+The `namespace` option is omitted, as this is built with `extension` and `plugin` name.
+
+The Extbase Plugin enhancer with the configuration below would now apply to the following URLs:
+
+   `index.php?id=13&tx_news_pi1[controller]=News&tx_news_pi1[action]=list`
+   `index.php?id=13&tx_news_pi1[controller]=News&tx_news_pi1[action]=list&tx_news_pi1[page]=5`
+   `index.php?id=13&tx_news_pi1[controller]=News&tx_news_pi1[action]=detail&tx_news_pi1[news]=13`
+   `index.php?id=13&tx_news_pi1[controller]=News&tx_news_pi1[action]=archive&tx_news_pi1[year]=2018&&tx_news_pi1[month]=8`
+
+And generate the following URLs
+
+   `https://www.example.com/path-to/my-page/list/`
+   `https://www.example.com/path-to/my-page/list/5`
+   `https://www.example.com/path-to/my-page/detail/13`
+   `https://www.example.com/path-to/my-page/archive/2018/8`
+
+:yaml:
+
+    routeEnhancers:
+      NewsPlugin:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/list/{page}', _controller: 'News::list', _arguments: {'page': '@widget_0/currentPage'} }
+          - { routePath: '/tag/{tag_name}', '_controller': 'News::list', '_arguments': {'tag_name': 'overwriteDemand/tags'}}
+          - { routePath: '/blog/{news_title}', _controller: 'News::detail', _arguments: {'news_title': 'news'} }
+          - { routePath: '/archive/{year}/{month}', _controller: 'News::archive' }
+        defaultController: 'News::list'
+        defaults:
+          page: '0'
+        requirements:
+          page: '\d+'
+
+
+In this example, you also see that the `_arguments` parameter can be used to bring them into sub properties of an array,
+which is typically the case within demand objects for filtering functionality.
+
+Aspects
+^^^^^^^
+
+Now that we've looked into ways on how to extend a route to a page with arguments, and to put them into the URL
+path as segments, the detailed logic within one placeholder is in an aspect. The most common practice of an aspect
+is a so-called mapper. Map `{news_title}` which is a UID within TYPO3 to the actual news title, which is a field
+within the database table.
+
+An aspect can be a way to modify, beautify or map an argument from the URL generation into a placeholder. That's why
+the terms "Mapper" and "Modifier" will pop up, depending on the different cases.
+
+Aspects are registered within one single enhancer configuration with the option `aspects` and can be used with any
+enhancer.
+
+Let's start with some simpler examples first:
+
+
+StaticValueMapper
+-----------------
+
+The StaticValueMapper replaces values simply on a 1:1 mapping list of an argument into a speaking segment, useful
+for a checkout process to define the steps into "cart", "shipping", "billing", "overview" and "finish", or in a
+simpler example to create speaking segments for all available months.
+
+The configuration could look like this:
+
+:yaml:
+
+    routeEnhancers:
+      NewsArchive:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/{year}/{month}', _controller: 'News::archive' }
+        defaultController: 'News::list'
+        defaults:
+          month: ''
+        aspects:
+          month:
+            type: StaticValueMapper
+            map:
+              january: 1
+              february: 2
+              march: 3
+              april: 4
+              may: 5
+              june: 6
+              july: 7
+              august: 8
+              september: 9
+              october: 10
+              november: 11
+              december: 12
+
+
+You'll see the placeholder "month" where the aspect replaces the value to a speaking segment.
+
+It is possible to add an optional `localeMap` to that aspect to use the locale of a value to use in multi-language
+setups.
+
+
+:yaml:
+
+    routeEnhancers:
+      NewsArchive:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/{year}/{month}', _controller: 'News::archive' }
+        defaultController: 'News::list'
+        defaults:
+          month: ''
+        aspects:
+          month:
+            type: StaticValueMapper
+            map:
+              january: 1
+              february: 2
+              march: 3
+              april: 4
+              may: 5
+              june: 6
+              july: 7
+              august: 8
+              september: 9
+              october: 10
+              november: 11
+              december: 12
+          localeMap:
+            - locale: 'de_.*'
+              map:
+                januar: 1
+                februar: 2
+                maerz: 3
+                april: 4
+                mai: 5
+                juni: 6
+                juli: 7
+                august: 8
+                september: 9
+                oktober: 10
+                november: 11
+                dezember: 12
+
+
+LocaleModifier
+--------------
+
+The enhanced part of a route path could be `/archive/{year}/{month}` - however, in multi-language setups, it should be
+possible to rename `/archive/` depending on the language that is given for this page translation. This modifier is a
+good example where a route path is modified but is not affected by arguments.
+
+The configuration could look like this:
+
+:yaml:
+
+    routeEnhancers:
+      NewsArchive:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/{localized_archive}/{year}/{month}', _controller: 'News::archive' }
+        defaultController: 'News::list'
+        aspects:
+          localized_archive:
+            type: LocaleModifier
+            default: 'archive'
+            localeMap:
+              - locale: 'fr_FR.*|fr_CA.*'
+                value: 'archives'
+              - locale: 'de_DE.*'
+                 value: 'archiv'
+
+You'll see the placeholder "localized_archive" where the aspect replaces the localized archive based on the locale of
+the language of that page.
+
+
+StaticRangeMapper
+-----------------
+
+A static range mapper allows to avoid the `cHash` and narrow down the available possibilities for a placeholder,
+and to explicitly define a range for a value, which is recommended for all kinds of pagination functionalities.
+
+:yaml:
+
+    routeEnhancers:
+      NewsPlugin:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/list/{page}', _controller: 'News::list', _arguments: {'page': '@widget_0/currentPage'} }
+        defaultController: 'News::list'
+        defaults:
+          page: '0'
+        requirements:
+          page: '\d+'
+        aspects:
+          page:
+            type: StaticRangeMapper
+            start: 1
+            end: 100
+
+This limits down the pagination to max. 100 pages, if a user calls the news list with page 101, then the route enhancer
+does not match and would not apply the placeholder.
+
+PersistedAliasMapper
+--------------------
+
+If an extension ships with a slug field, or a different field used for the speaking URL path, this database field
+can be used to build the URL:
+
+:yaml:
+
+    routeEnhancers:
+      NewsPlugin:
+        type: Extbase
+        limitToPages: [13]
+        extension: News
+        plugin: Pi1
+        routes:
+          - { routePath: '/detail/{news_title}', _controller: 'News::detail', _arguments: {'news_title': 'news'} }
+        defaultController: 'News::detail'
+        aspects:
+          news_title:
+            type: PersistedAliasMapper
+            tableName: 'tx_news_domain_model_news'
+            routeFieldName: 'path_segment'
+            valueFieldName: 'uid'
+            routeValuePrefix: '/'
+
+The PersistedAliasMapper looks up (via a so-called delegate pattern under the hood) to map the given value to a
+a URL. The property `tableName` points to the database table, property `routeFieldName` is the field which will be
+used within the route path, and the `valueFieldName` is the argument that is used within the Extbase plugin for
+example.
+
+The special `routeValuePrefix` is used for TCA type `slug` fields where the prefix `/` is within all fields of the
+field names, which should be removed in the case above.
+
+If a field is used for `routeFieldName` that is not prepared to be put into the route path, e.g. the news title field,
+it still must be ensured that this is unique. On top, if there are special characters like spaces they will be
+URL-encoded, to ensure a definitive value, a slug TCA field is recommended.
+
+PersistedPatternMapper
+----------------------
+
+When a placeholder should be fetched from multiple fields of the database, the PersistedPatternMapper is for you.
+It allows to combine various fields into one variable, ensuring a unique value by e.g. adding the UID to the field
+without having the need of adding a custom slug field to the system.
+
+:yaml:
+
+    routeEnhancers:
+      Blog:
+        type: Extbase
+        limitToPages: [13]
+        extension: BlogExample
+        plugin: Pi1
+        routes:
+          - { routePath: '/blog/{blogpost}', _controller: 'Blog::detail', _arguments: {'blogpost': 'post'} }
+        defaultController: 'Blog::detail'
+        aspects:
+          blogpost:
+            type: PersistedPatternMapper
+            tableName: 'tx_blogexample_domain_model_post'
+            routeFieldPattern: '^(?P<title>.+)-(?P<uid>\d+)$'
+            routeFieldResult: '{title}-{uid}'
+
+The `routeFieldPattern` option builds the title and uid fields from the database, the `routeFieldResult` shows
+how the placeholder will be output.
+
+Impact
+======
+
+Some notes to the implementation:
+
+While accessing a page in TYPO3 in the Frontend, all arguments are currently built back into the global
+GET parameters, but also available as so-called `PageArguments` object, which is then used to be signed and verified
+that they are valid, when handing them to process a frontend request further.
+
+If there are dynamic parameters (= parameters which are not strictly limited), a verification GET parameter `cHash`
+is added, which can and should not be removed from the URL. The concept of manually activating or deactivating
+the generation of a `cHash` is not optional anymore, but strictly built-in to ensure proper URL handling. If you
+really have the requirement to never have a cHash argument, ensure that all placeholders are having strict definitions
+on what could be the result of the page segment (e.g. pagination), and feel free to build custom mappers.
+
+Setting the TypoScript option `typolink.useCacheHash` is not necessary anymore when running with a site configuration.
+
+Please note that Enhancers and Page-based routing is only available for pages that are built with a site configuration.
+
+All existing APIs like `typolink` or functionality evaluate the new Page Routing API directly and come with route
+enhancers.
+
+Please note that if you update the Site configuration with enhancers that you need to clear all caches.
