Use Cases

Below are the use cases address by this Layout library. The current implementation provides features/solutions for all listed user cases.

Layout elements in rows
Layout elements in columns
Nested containers should have isolated layout constraints
Adjust container children sizes (flex) based on static percentages
Adjust container children sizes (flex) based on static pixel values
Adjust container children sizes (flex) based on expressions
Adjust alignment of container children based on static/dynamic values
Adjust offset of container children based on static/dynamic values
Adjust ordering of container children based on static/dynamic values
Container children resizing (flex) is dependent upon container layout directions (layout)
Changes in Layout directives will update nested Flex children

Change Detection: ngOnChanges due to Layout attribute expressions only trigger for defined activated breakpoints or used as fallback
- Input changes are filtered so the default input key is used if the activation key is not defined
- Input changes are filtered so only the current activated input change will trigger an update
Activations: when the mediaQuery becomes active
- mq Activation only uses expressions for the activated breakpoint
- mq Activation fallback to use to non-responsive expressions (fallback) if no breakpoint defined
Subscription notifications: using MatchMedia and MediaMonitor
- ResponsiveActivation internally uses MediaMonitor to subscribe to mediaQuery activation changes
- MediaChange will contain the current activation information
Querying: for imperative or template logic
- Components can dependency-inject the MatchMediaObservable and subscribe to all activations. See Demo Example
Breakpoint Customization:
- Custom set of breakpoints can be defined as a Provider
- Custom breakpoints will override ALL default breakpoints (no merging)
