Changelog

1.5.1

  • 🐛 Updated getDerivedState Flow annotations to address a warning in a newer version of Flow.

1.5.0

  • 🎉 Added advanced memoization helpers methods areEqual and shouldComponentUpdate for item renderers. - #114

1.4.0

  • 🎉 List and Grid components now "overscan" (pre-render) in both directions when scrolling is not active. When scrolling is in progress, cells are only pre-rendered in the direction being scrolled. This change has been made in an effort to reduce visible flicker when scrolling starts without adding additional overhead during scroll (which is the most performance sensitive time).
  • 🎉 Grid components now support separate overscanColumnsCount and overscanRowsCount props. Legacy overscanCount prop will continue to work, but with a deprecation warning in DEV mode.
  • 🐛 Replaced setTimeout with requestAnimationFrame based timer, to avoid starvation issue for isScrolling reset. - #106
  • 🎉 Renamed List and Grid innerTagName and outerTagName props to innerElementType and outerElementType to formalize support for attaching arbitrary props (e.g. test ids) to List and Grid inner and outer DOM elements. Legacy innerTagName and outerTagName props will continue to work, but with a deprecation warning in DEV mode.
  • 🐛 List re-renders items if direction prop changes. - #104

1.3.1

  • 🎉 Pass itemData value to custom itemKey callbacks when present - #90)

1.3.0

  • (Skipped)

1.2.4

  • 🐛 Added Flow annotations to memoized methods to avoid a Flow warning for newer versions of Flow

1.2.3

  • 🐛 Relaxed children validation checks. They were too strict and didn't support new React APIs like memo.

1.2.2

  • 🐛 Improved Flow types for class component item renderers - (nicholas-l - #77)

1.2.1

  • 🎉 Improved Flow types to include optional itemData parameter. (TrySound - #66)
  • 🐛 VariableSizeList and VariableSizeGrid no longer call size getter functions with invalid index when item count is zero.

1.2.0

  • 🎉 Flow types added to NPM package. (TrySound - #40)
  • 🎉 Relaxed grid scrollTo method to make scrollLeft and scrollTop params optional (so you can only update one axis if desired). - #63)
  • 🐛 Fixed invalid this pointer in VariableSizeGrid that broke the resetAfter* methods - #58)
  • Upgraded to babel 7 and used shared runtime helpers to reduce package size slightly. (TrySound - #48)
  • Remove overflow:hidden from inner container (souporserious - #56)

1.1.2

  • 🐛 Fixed edge case scrollToItem bug that caused lists/grids with very few items to have negative scroll offsets.

1.1.1

  • 🐛 FixedSizeGrid and FixedSizeList automatically clear style cache when item size props change.

1.1.0

  • 🎉 Use explicit constructor and super to generate cleaner component code. (Andarist - #26)
  • 🎉 Add optional shouldForceUpdate param reset-index methods to specify forceUpdate behavior. (nihgwu - #32)

1.0.3

  • 🐛 Avoid unnecessary scrollbars for lists (e.g. no horizontal scrollbar for a vertical list) unless content requires them.

1.0.2

  • 🎉 Enable Babel annotate-pure-calls option so that classes compiled by "transform-es2015-classes" are annotated with #__PURE__. This enables UglifyJS to remove them if they are not referenced, improving dead code elimination in application code. (Andarist - #20)
  • 🎉 Update "rollup-plugin-peer-deps-external" and use new includeDependencies flag so that the "memoize-one" dependency does not get inlined into the Rollup bundle. (Andarist - #19)
  • 🎉 Enable Babel "loose" mode to reduce package size (-8%). (Andarist - #18)

1.0.1

Updated README.md file to remove @alpha tag from NPM installation instructions.

1.0.0

Initial release of library. Includes the following components:

  • FixedSizeGrid
  • FixedSizeList
  • VariableSizeGrid
  • VariableSizeList
