Hooks
State
-
use_toggle
- tracks state of counterparts. -
use_bool_toggle
- tracks state of a boolean. -
use_counter
- tracks state of a number. -
use_latest
- returns the latest immutable ref to state or props. -
use_mut_latest
- returns the latest mutable ref to state or props. -
use_previous
- returns the previous immutable ref to state or props. -
use_list
- tracks state of a list. -
use_map
- tracks state of a hash map. -
use_set
- tracks state of a hash set. -
use_queue
- tracks state of a queue. -
use_raf_state
- createsset
method which only updates afterrequestAnimationFrame
. -
use_state_ptr_eq
- similar touse_state_eq
, but checks if the twoRc
s of values point to the same allocation. -
use_renders_count
- counts component renders. -
use_default
- returns the default value when state is None. -
use_debounce_state
- debounces state. -
use_throttle_state
- throttles state.
Side-effects
-
use_async
- resolves anasync
future, e.g. fetching REST api. -
use_websocket
- communicates withWebSocket
. -
use_title
- sets title of the page. -

. -
use_session_storage
- manages a value insessionStorage
. -
use_before_unload
- shows browser alert when user try to reload or close the page. -
use_debounce
- debounces a function. -
use_debounce_effect

use_throttle
- throttles a function. -
use_throttle_effect
- throttles an effect. -
use_clipboard
- reads from or writes to clipboard for text/bytes.
Lifecycles
-
use_effect_once
- a modified use_effect hook that only runs once. -
use_effect_update
- runs an effect only on updates. -
use_mount
- calls mount callbacks. -
use_unmount
- calls unmount callbacks. -
use_is_first_mount
- checks if current render is first. -
use_is_mounted
- tracks if component is mounted. -
use_event
- subscribes to events. -
use_logger
- logs in console as component goes through life cycles.
Animations
-
use_timeout
- schedules a timeout to invoke callback. -
use_interval
- schedules an interval to invoke callback. -
use_update
- returns a callback, which re-renders component when called. -
use_raf
- re-renders component on eachrequestAnimationFrame
.
Sensors
-
use_window_size
- tracks Window dimensions. -
use_window_scroll
- tracks Window scroll position. -
use_scroll
- tracks an HTML element's scroll position. -
use_scrolling
- tracks whether HTML element is scrolling. -
use_infinite_scroll

use_hash
- tracks brower's location hash value. -
use_search_param
- tracks brower's location search param value. -

API. -

hook. -
use_drop
- tracks file, link and copy-paste drops. -
use_media
