Installation

  1. 1

    Install dependencies:

    npm i recharts
  2. 2

    Add useOnWindowResize.ts hook:

    Copy and paste the code into your project’s hooks or component directory.
    // Tremor Raw useOnWindowResize [v0.0.0]
    import * as React from "react"
    export const useOnWindowResize = (handler: { (): void }) => {  React.useEffect(() => {    const handleResize = () => {      handler()    }    handleResize()    window.addEventListener("resize", handleResize)
        return () => window.removeEventListener("resize", handleResize)  }, [handler])}
    
  3. 3

    Add component:

    Copy and paste the code into your project’s component directory. Do not forget to update the import paths. If you have not added the required chartUtils.ts, check out the add utilities and helpers section in installation.
