Studying Angular

Primary entry point exports Functions  -  style The "style" function in Angular Animation API is used to declare a key/value object containing CSS properties and styles. This object can then be utilized for defining an animation state, within an animation sequence, or as styling data for calls to animate() and keyframes() functions. This function provides flexibility in associating styles with animation states, and it supports various forms of input for defining CSS styles. Here is a detailed breakdown of the style function and its parameters: Parameters:      tokens ("*" | { [key: string]: string | number; } | ("*" | { [key: string]: string | number; })[]"):          - A set of CSS styles or HTML styles associated with an animation state.                    -  The value can be any of the following:               - A key-value style pair associating a CSS property with a value.               - An array of key-value style pairs.     

Primary entry point exports Functions - state The "state" function is part of the Angular Animation API and is used to declare an animation state within a trigger that is attached to an HTML element. This function allows you to define named states and associate them with specific styles. These states can then be used in conjunction with the "trigger" and "transition" functions to create animations in Angular applications. Here is a detailed breakdown of the "state" function and its parameters: Parameters:      name (string):          -  One or more names for the defined state , provided as a comma-separated string.                    -  Reserved state names can be used to define styles for specific use cases.                            - void: Used for styling when the element is detached from the application ( e.g. , when an ngIf evaluates to false).               -  * (asterisk): Indicates the default state . Styles associated w

Primary entry point exports Functions  -  stagger The "stagger" function in Angular animations is used within an animation query() call to introduce a timing gap after each queried item is animated. This is particularly useful when you want to create a stagger effect, where each item in a sequence starts its animation with a delay relative to the previous item. Stagger Function: The "stagger" function in Angular introduces a delay after each queried item's animation within an animation query() . It takes two parameters:     -  'timings': A delay value (string or number) that represents the timing gap.     - ' animation': One or more animation steps represented by AnimationMetadata or an array of AnimationMetadata . It returns an object of type AnimationStaggerMetadata that encapsulates the stagger data. Usage in Animation Trigger: In the animation trigger named 'listAnimation' , there is a transition defined for any change

Primary entry point exports Functions  -  sequence The "sequence" function is used to define a list of animation steps that will be executed sequentially, one after the other. It takes an array of animation step objects as its main parameter and an optional options object. Here's a breakdown of the key components: Function Signature:     - steps: An array of animation step objects. Each step can be created using the style() or animate() calls.     - options: An optional object containing parameters such as delay and developer-defined options. The default value is "null" . Example: In this example, a sequence is created with two steps. The first step sets the initial opacity to 0 using the style() call, and the second step animates the opacity to 1 over a duration of 1 second using the animate() call. Options: The "options" parameter allows you to provide an options object that can contain properties like delay and other developer-defined p

Primary entry point exports Functions  - query The "query" function in Angular Animation is used to find one or more inner elements within the current element being animated in a sequence. This function is particularly powerful when used with the animate() function. Here's a detailed explanation with a different example: Syntax: Parameters:     1.  selector (required): The element to query or a set of elements specified with Angular-specific tokens. Tokens include ":enter" , ":leave" , ":animating" , "@triggerName" , "@*", and ":self" .     2.  animation (required): One or more animation steps to apply to the queried element or elements. An array is treated as an animation sequence.     3.  options (optional): An options object, including the "limit" field to limit the total number of items to collect. Default is "null" . Example: Usage Explanation: In this example, the "que

Primary entry point exports Functions  -  keyframes The "keyframes" function in Angular Animation is utilized to define a sequence of animation styles, associating each style with an optional offset  value. This function is particularly powerful when used with the animate() call, providing a way to describe how each style entry is applied and at what point within the animation timeline. Here are the details of this function: Syntax: Parameters:     -  steps (required): An array of animation style objects. Each style object represents a set of CSS styles to be applied at a specific point in the animation sequence. The "offset" property is optional and represents the percentage of the total animation time at which the style is applied. Example: In this example, the "keyframes" function is used to define a sequence of background colors over a 5-second animation. The "offset" values determine when each background color is applied, creating

Primary entry point exports Functions - group The "group" function in Angular Animation is used to define a list of animation steps that will be executed in parallel. This is useful when you want to animate multiple properties simultaneously or when you need to run several animations at the same time. Here are the details of this function: Syntax: Parameters:     - steps (required): An array of animation step objects. Each step is defined using functions like style() or animate() .     -  options (optional): An options object containing delay and developer-defined parameters that provide styling defaults and can be overridden when invoking the animation. The default is "null" . Example: In this example, we have an animation that changes the background color to black in 1 second and the text color to white in 2 seconds. Both animations occur simultaneously due to the use of the "group" function. Usage Notes:     1.  Instant Execution: When st

Primary entry point exports Functions -  animation The "animation" function in Angular animations is a powerful tool that allows you to produce reusable animations. These animations can be invoked in other animations or sequences by calling the useAnimation function. Let's dive into the details with a more elaborate example: Function: Parameters: The "steps" property is one of the parameters of this animation function, and it refers to one or more animation objects that form a transformation from one state to another. These animation objects are typically created using the animate() or sequence() functions.     -  steps:    This parameter accepts either a single animation object ("AnimationMetadata") or an array of animation objects ("AnimationMetadata[]") . Each animation object represents a step or a specific transformation in the animation. The "options" property is one of the parameters of this "animation"

Primary entry point exports Functions -  animateChild The animateChild function in Angular animations is a powerful tool used to execute a queried inner animation element within an animation sequence. Let's delve into the details: Function: Parameters:     -  options (optional): An object of type AnimateChildOptions that can contain a delay value for the start of the animation and additional override values for developer-defined parameters. The default value is null. Returns:     -  An object of type AnimationAnimateChildMetadata that encapsulates the child animation data.      Usage Notes:         1.  Parent-Child Relationship:               -  Each time an animation is triggered in Angular , the parent animation takes priority, and any child animations are blocked by default.                              -  To enable a child animation to run, the parent animation must query each element containing child animations and execute them using the animateChild function.        

Primary entry point exports Functions  -  animate Introduction: The "animate" function in Angular animations is a fundamental building block within the animation DSL (Domain-Specific Language) . It plays a crucial role in defining animation steps, combining styling information with timing details. Typically employed within the "transition" and "trigger" functions, it provides developers with a robust mechanism for creating dynamic and visually appealing animations. Function Overview: Timing Parameter:     -  Specifies the duration of the animation and the timing function.     -  Can be a string representing a predefined timing function ( e.g ., "ease-in" , "ease-out" ) or a number representing the duration in milliseconds. Styles Parameter:     -  Defines the styles that the element should have at the end of the animation.     -  Can be a set of CSS styles, keyframes, or null to indicate no styles at the end.
