Describe your issue

When attempting to use the resolveConfig helper in a typescript project you get a type error Could not find a declaration file for module 'tailwindcss/resolveConfig'.

[joshmossas]

For anyone that needs a quick work-around, create a .d.ts file (ex tailwind-resolve-config.d.ts) in your types/typings directory with the following

declare module 'tailwindcss/resolveConfig' {
    import type { Config } from 'tailwindcss';

    declare function resolveConfig(config: Config): Config;
    export = resolveConfig;
}

Hey, I merged in your PR. This will be in our insiders build until we tag a new release (likely tomorrow). Thanks again for the PR! 🎉

I am using some utils, would be nice if all of them had types. Here is what I've done to add some.

declare module "tailwindcss/src/util/normalizeScreens" {
  import {
    ResolvableTo,
    Screen,
    ScreensConfig,
  } from "tailwindcss/types/config";

  type ScreenDefinition = {
    name: string;
    values: Screen;
  };

  export function normalizeScreens(
    screens: ResolvableTo<ScreensConfig>
  ): ScreenDefinition[];
}

declare module "tailwindcss/src/util/buildMediaQuery" {
  import { ScreenDefinition } from "tailwindcss/src/util/normalizeScreens";

  function buildMediaQuery(screen: ScreenDefinition): string;

  export = buildMediaQuery;
}

@robclancy Those utils are not part of the Tailwind CSS public API so we are not likely to add types for them.

If it's not part of your public API, why is it on your public documentation?

@Sidnioulz No they're not. My comment was about normalizeScreens and buildMediaQuery from the comment above hence why I was replying to said comment. I was not talking about resolveConfig.

@thecrypticace aaaand I read too fast. My sincerest apologies! 😱

@Sidnioulz All good!
