-### 1.7.1 -* 🐛 Fix SSR regression introduced in 1.7.0 - ([Betree](https://github.com/Betree) - [#185](https://github.com/bvaughn/react-window/pull/185)) - -### 1.7.0 -* 🎉 Grid `scrollToItem` supports optional `rowIndex` and `columnIndex` params ([jgoz](https://github.com/jgoz) - [#174](https://github.com/bvaughn/react-window/pull/174)) -* DEV mode checks for `WeakSet` support before using it to avoid requiring a polyfill for IE11 - ([jgoz](https://github.com/jgoz) - [#167](https://github.com/bvaughn/react-window/pull/167)) - -### 1.6.2 -* 🐛 Bugfix for RTL when scrolling back towards the beginning (right) of the list. - -### 1.6.1 -* 🐛 Bugfix to account for differences between Chrome and non-Chrome browsers with regard to RTL and "scroll" events. - -### 1.6.0 -* 🎉 RTL support added for lists and grids. Special thanks to [davidgarsan](https://github.com/davidgarsan) for his support. - [#156](https://github.com/bvaughn/react-window/pull/156) -* 🐛 Grid `scrollToItem` methods take scrollbar size into account when aligning items - [#153](https://github.com/bvaughn/react-window/issues/153) - -### 1.5.2 -* 🐛 Edge case bug fix for `VariableSizeList` and `VariableSizeGrid` when the number of items decreases while a scroll is in progress. - ([iamsolankiamit](https://github.com/iamsolankiamit) - [#138](https://github.com/bvaughn/react-window/pull/138)) - -### 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](https://github.com/bvaughn/react-window/issues/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](https://github.com/bvaughn/react-window/issues/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.

([TrySound](https://github.com/TrySound) - [#40](https://github.com/bvaughn/react-window/pull/40)) -* 🎉 Relaxed grid `scrollTo` method to make `scrollLeft` and `scrollTop` params _optional_ (so you can only update one axis if desired). - [#63](https://github.com/bvaughn/react-window/pull/63)) -* 🐛 Fixed invalid `this` pointer in `VariableSizeGrid` that broke the `resetAfter*` methods - [#58](https://github.com/bvaughn/react-window/pull/58)) -* Upgraded to babel 7 and used shared runtime helpers to reduce package size slightly. ([TrySound](https://github.com/TrySound) - [#48](https://github.com/bvaughn/react-window/pull/48)) -* Remove `overflow:hidden` from inner container ([souporserious](https://github.com/souporserious) - [#56](https://github.com/bvaughn/react-window/pull/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](https://github.com/Andarist) - [#26](https://github.com/bvaughn/react-window/pull/26)) -* 🎉 Add optional `shouldForceUpdate` param reset-index methods to specify `forceUpdate` behavior. ([nihgwu](https://github.com/nihgwu) - [#32](https://github.com/bvaughn/react-window/pull/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](https://github.com/mishoo/UglifyJS2/pull/1448), improving dead code elimination in application code. ([Andarist](https://github.com/Andarist) - [#20](https://github.com/bvaughn/react-window/pull/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](https://github.com/Andarist) - [#19](https://github.com/bvaughn/react-window/pull/19)) -* 🎉 Enable [Babel "loose" mode](https://babeljs.io/docs/en/babel-preset-env#loose) to reduce package size (-8%). ([Andarist](https://github.com/Andarist) - [#18](https://github.com/bvaughn/react-window/pull/18)) - -### 1.0.1 -Updated `README.md` file to remove `@alpha` tag from NPM installation instructions. - -# 1.0.0 -Initial release of library.

At the time, I was new to both React and the concept of windowing. Because of this, I made a few API decisions that I later came to regret. One of these was adding too many non-essential features and components. Once you add something to an open source project, removing it is pretty painful for users. - -`react-window` is a complete rewrite of `react-virtualized`. I didn't try to solve as many problems or support as many use cases. Instead I focused on making the package **smaller**1 and **faster**. I also put a lot of thought into making the API (and documentation) as beginner-friendly as possible (with the caveat that windowing is still kind of an advanced use case). - -If `react-window` provides the functionality your project needs, I would strongly recommend using it instead of `react-virtualized`. However if you need features that only `react-virtualized` provides, you have two options: - -1. Use `react-virtualized`. (It's still widely used by a lot of successful projects!) -2. Create a component that decorates one of the `react-window` primitives and adds the functionality you need. You may even want to release this component to NPM (as its own, standalone package)! 🙂 - -1 - Adding a `react-virtualized` list to a CRA project increases the (gzipped) build size by ~33.5 KB. Adding a `react-window` list to a CRA project increases the (gzipped) build size by <2 KB. - -### Can a list or a grid fill 100% the width or height of a page? - -Yes. I recommend using the [`react-virtualized-auto-sizer` package](https://npmjs.com/package/react-virtualized-auto-sizer): - -screen shot 2019-03-07 at 7 29 08 pm - -Here's a [Code Sandbox demo](https://codesandbox.io/s/3vnx878jk5). - -### Why is my list blank when I scroll? - -If your list looks something like this... - - - -...then you probably forgot to use the `style` parameter! Libraries like react-window work by absolutely positioning the list items (via an inline style), so don't forget to attach it to the DOM element you render! - -screen shot 2019-03-07 at 7 21 48 pm - -### Can I lazy load data for my list? - -Yes.
