Bump reselect from 4.1.8 to 5.0.1

[dependabot]

Bumps reselect from 4.1.8 to 5.0.1.

Release notes

Sourced from reselect's releases.

v5.0.0

This major release:

• Switches createSelector to use a new weakMapMemoize method as the default memoizer
• Renames the existing defaultMemoize method to lruMemoize
• Adds new configuration options to createSelector
• Adds new development mode checks
• Updates the packaging for better ESM/CJS compatibility and modernizes the build output
• Makes significant updates to the TS types.

This release has breaking changes. (note: this points to v5.0.1, which contains a hotfix that was released prior to the announcement.)

This release is part of a wave of major versions of all the Redux packages: Redux Toolkit 2.0, Redux core 5.0, React-Redux 9.0, Reselect 5.0, and Redux Thunk 3.0.

For full details on all of the breaking changes and other significant changes to all of those packages, see the "Migrating to RTK 2.0 and Redux 5.0" migration guide in the Redux docs.

We have a new docs site! The Reselect docs are now at https://reselect.js.org.

[!NOTE] The Redux core, Reselect, and Redux Thunk packages are included as part of Redux Toolkit, and RTK users do not need to manually upgrade them - you'll get them as part of the upgrade to RTK 2.0. (If you're not using Redux Toolkit yet, please start migrating your existing legacy Redux code to use Redux Toolkit today!)

# RTK
npm install @reduxjs/toolkit
yarn add @reduxjs/toolkit
Standalone
npm install reselect
yarn add reselect

Changelog

createSelector Uses weakMapMemoize By Default

Reselect's createSelector originally only had one memoization function, which has originally called defaultMemoize (and per below, is now renamed to lruMemoize). It's always used a customizable comparison method to compare each argument. Over time, we added more functionality, particularly in v4.1.0 where lruMemoize gained options for {memoize, maxSize, resultEqualityCheck}.

However, lruMemoize has limitations. The biggest one is that the default cache size is 1. This makes selector instances hard to reuse in scenarios like list items, which might call selectSomeValue(state, props.id), and thus never actually memoize due to changing arguments. There are workarounds, but they're cumbersome - using createSelectorCreator to create a customized createSelector function with a different memoization implementation, creating unique selector instances per component, or setting a fixed maxSize.

For 5.0, we added a new weakMapMemoize memoization function, which takes a different approach (as originally implemented in the React codebase). It uses an internal tree of cache nodes rather than a single value or a list of values. This gives weakMapMemoize an effectively infinite cache size!

We've done a fair amount of testing, and weakMapMemoize both performs faster and has more frequent cache hits than lruMemoize.

Given that, we've made the switch so that createSelector uses weakMapMemoize by default! This should result in better performance for Redux and React apps that use Reselect.

This is hopefully a mostly non-breaking change at the code level, and an overall improvement at the behavior level.

This is a breaking change. weakMapMemoize does not have an equalityCheck option or allow customizing the comparison behavior - it's entirely based on reference comparisons, since it uses WeakMap/Map internally. It also does not have a maxSize option, but does have resultEqualityCheck.

If you need to customize the overall equality comparison behavior, import and pass lruMemoize as the memoize and argsMemoize option!
