Vueuse Math Skilld

What it does

The Vueuse Math Skilld provides a collection of reactive math functions and utilities specifically designed for use within Vue.js applications. It simplifies complex calculations, allowing for dynamic data manipulation and improved performance. The skill includes features like calculating averages and sums reactively, creating numeric projections between domains, and providing reactive wrappers around common JavaScript Math methods.

When to use it

This skill is useful in scenarios such as:

• Creating interactive charts or graphs that require real-time scaling of data.
• Implementing input validation where values need to be clamped within a specific range.
• Performing ad-hoc calculations with multiple reactive variables, like calculating totals or averages.
• Dynamically adjusting numeric ranges based on user interaction or changing conditions.

Key capabilities

• useAverage: Reactively calculates the average of an array or variadic arguments.
• useSum: Reactively calculates the sum of an array or variadic arguments.
• createProjection and createGenericProjection: Creates reusable numeric projectors between domains, with custom mapping functions for arbitrary types.
• Reactive wrappers for common Math methods: useAbs, useCeil, useFloor, useRound, useTrunc.
• useMax and useMin: Reactively compares values in an array or using variadic arguments.
• logicAnd, logicOr, logicNot: Reactive boolean logic supporting multiple refs.
• Provides reactive access to standard Math methods via useMath.

Example prompts

While this is a skill for code, here are examples of what a developer might say when using it:

• "Create a reactive average calculation from these three numbers."
• "Clamp this value between 0 and 10."
• "Project the data range from 0 to 100 to a different scale for my chart."

Tips & gotchas

• Requires Vue 3.5 or later due to native useTemplateRef and MaybeRefOrGetter.
• CommonJS (CJS) support has been dropped; this skill uses ESM only.
• For clamping, use a mutable ref for automatic validation – the returned computed ref will clamp any assigned value.
