What is this?

This is compilation of random utilities for building React apps.

Should I use this?

Currently it's not to be considered stable.

Use at your own discretion and don't rely on anything staying backward compatible.

What utilities are included here?

• abortable

  A wrapper for effects that use an AbortSignal.

• asynced

  A wrapper for async effects.

• Nested

  A component that handles nesting multiple no args components.

• nonexistent

  A symbol/type to mark state as non-existent.

• noop

  An empty function. Useful when such a function is required and it being a stable value is preferable.

• onClickOutside

  A helper for setting up listener to clicks that happen outside an element.

• pending

  A symbol/type to mark state as pending.

• preventDefault

  A function that calls preventDefault on its first argument. Useful for some use cases with event handlers.

• pushState

  A function to push an url/state into navigation history. Also triggers the corresponding popstate event.

• useBoolean

  An useState alternative for boolean flags.

• useBooleanToggle

  Another useState alternative for boolean flags.

• useCursor

  A useState alternative for handling cursors over numerically indexed lists (e.g. pagination).

• useFunctionRef

  A mutable function reference. Useful when you need to keep a callback for later without keeping it as part of the component state.

• useLoadingFlag

  A hook for dynamically keeping track of one or more Promises and providing a flag that indicates whether there are pending Promises or not.

• useLocation

  Returns the current URL and causes the component to rerender when it changes. Useful to handle URL routing yourself.

• useMediaQuery

  Indicates whether the current viewport matches a media query and causes a rerender if the condition changes.

• useMutable

  A hook for handling a mutable value. Useful for keeping track of data during the component lifecycle that does not need to be part of the component state.

• useResizeDetect

  A flag which indicates when the viewport is view resized.

• useSharedState

  A way for components to share state and/or prevent unnecessary rerenders and coupling between parent and child components.

• useSingleton

  An alternative to React's useContext.

• useUnmountSignal

  An AbortSignal that triggers when the component unmounts. Useful for async callbacks that need to be aborted when the component unmounts.
