Utility to transparentize Chakra UI color tokens
import { ThemeTypings } from '@chakra-ui/react'
/**
* Transparentize Chakra UI color tokens
* @param color - Chakra UI (semantic) token
* @param opacity - Opacity value 0 to 1.
*/
export const alpha = (color: ThemeTypings['colors'], value: number) => {
const key = color.replaceAll('.', '-')
return `color-mix(in srgb, var(--chakra-colors-${key}) ${Math.max(Math.min(value * 100, 100), 0)}%, transparent)`

Next.js SPA example with dynamic client-only routing and static hosting

Next.js client-only SPA example

Made this example to show how to use Next.js router for a 100% SPA (no JS server) app.

You use Next.js router like normally, but don't define getStaticProps and such. Instead you do client-only fetching with swr, react-query, or similar methods.

You can generate HTML fallback for the page if there's something meaningful to show before you "know" the params. (Remember, HTML is static, so it can't respond to dynamic query. But it can be different per route.)

Don't like Next? Here's how to do the same in Gatsby.

Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.
