  1. CORE
    2. 

  2. ====
    3. 

  3. core  | use_hook              | Store a value between renders. The foundational hook for all other hooks.
    4. 

  4. 

  5. LIFECYCLE
    6. 

  6. =========
    7. 

  7. hooks | use_effect            | Run closure after the component has finished rendering.
    8. 

  8. core  | use_drop              | Creates a callback that will be run before the component
    9. 

  9. hooks | use_on_unmount        | DEPRECATED. Alias for use_drop.
    10. 

  10. core  | use_hook_with_cleanup | Like `use_hook` and `use_drop` combined
    11. 

  11. core  | use_before_render     | Safely handle "early returns"
    12. 

  12. core  | use_after_render      | Safely handle "early returns" HOW DOES THIS DIFFER FROM `before_render`?
    13. 

  13. 

  14. LOCAL STATE
    15. 

  15. ===========
    16. 

  16. hooks | use_signal            | Creates a new Signal (state with automatic dependency tracking)
    17. 

  17. hooks | use_memo              | Creates a new Memo. Eefficiently compute derived data from signals.
    18. 

  18. 

  19. Advanced:
    20. 

  20. hooks | use_signal_sync       | Creates a new Signal that is `Send + Sync`
    21. 

  21. hooks | use_set_compare       | Creates a new SetCompare which efficiently tracks when a value changes to check if it is equal to a set of values.
    22. 

  22. hooks | use_set_compare_equal | A hook that returns true if the value is equal to the value in the set compare.
    23. 

  23. 

  24. CALLBACK (closed over state)
    25. 

  25. ========
    26. 

  26. hooks | use_callback          | Create a callback that’s always up to date. Whenever this hook is called the inner callback will be replaced with the new callback but the handle will remain.
    27. 

  27. 

  28. NON-LOCAL STATE
    29. 

  29. ===============
    30. 

  30. hooks | use_context_provider  | Provide some context via the tree and return a reference to it
    31. 

  31. hooks | use_context           | Consume some context in the tree, providing a sharable handle to the value
    32. 

  32. hooks | try_use_context       | Consume some context in the tree, providing a sharable handle to the value
    33. 

  33. hooks | use_root_context      | Try to get a value from the root of the virtual dom, if it doesn’t exist, create a new one with the closure provided.
    34. 

  34. 

  35. ASYNC
    36. 

  36. =====
    37. 

  37. hooks | use_resource          | Derive a value using an future / async closure (re-run each time derived values change).
    38. 

  38. 

  39. Advanced:
    40. 

  40. hooks | use_future            | A hook that allows you to spawn a future the first time you render a component.
    41. 

  41. hooks | use_coroutine         | Maintain a handle over a future that can be paused, resumed, and canceled.
    42. 

  42. hooks | use_coroutine_handle  | Get a handle to a coroutine higher in the tree
    43. 

  43. 

  44. NOT SURE
    45. 

  45. ========
    46. 

  46. hooks | use_reactive          | Takes non-reactive data, and a closure and subscribes to that non-reactive data as if it were reactive.
    47. 

  47. hooks | use_hook_did_run      | A hook that uses before/after lifecycle hooks to determine if the hook was run
    48.
