Install from the NPM repository using yarn or npm:
yarn add reselect-utils
npm install reselect-utils
Such projects as Reselect and Re-reselect try to solve the task of memoization. But there is no standard solutions for some applied problems. This library was created to try to systematically solve the following problems:
- Work with optional objects as a source for selection.
- Binding parametric selectors to specific property values.
- Adaptation of parametric selectors to the new parameter interface (useful for creating parametric structured selectors).
- Using selection results as parameters for a new selection.
- Calculating the aggregate value from a collection of selector results.
- Structuring of selection results (more proper typed version of structured selector and cached structured selector).
- Implementation of key selectors composition (useful for key selector creator usages).
Reselect Utils is inspired by projects such as Reselect, Re-reselect and ts-optchain. Also functional programming principles are used for design of this library. For example, Chain Selector was inspired by Monad Pattern.
