@solid-primitives/media

@solid-primitives/media

Collection of reactive primitives to deal with media queries.

• makeMediaQueryListener - Listen for changes to provided Media Query.
• createMediaQuery - Creates a very simple and straightforward media query monitor.
• createBreakpoints - Creates a multi-breakpoint monitor to make responsive components easily.
• createPrefersDark - Provides a signal indicating if the user has requested dark color theme.

Installation

npm install @solid-primitives/media
# or
yarn add @solid-primitives/media

makeMediaQueryListener

Attaches a MediaQuery listener to window, listeneing to changes to provided query

import { makeMediaQueryListener } from "@solid-primitives/media";

const clear = makeMediaQueryListener("(max-width: 767px)", e => {
  console.log(e.matches);
});
// remove listeners (will happen also on cleanup)
clear();

createMediaQuery

Creates a very simple and straightforward media query monitor.

import { createMediaQuery } from "@solid-primitives/media";

const isSmall = createMediaQuery("(max-width: 767px)");
console.log(isSmall());

Server fallback

createMediaQuery accepts a serverFallback argument — value that should be returned on the server — defaults to false.

const isSmall = createMediaQuery("(max-width: 767px)", true);

// will return true on the server and during hydration on the client
console.log(isSmall());

Working Demo

createBreakpoints

Creates a multi-breakpoint monitor to make responsive components easily.

import { createBreakpoints } from "@solid-primitives/media";

const breakpoints = {
  sm: "640px",
  lg: "1024px",
  xl: "1280px",
};

const Example: Component = () => {
  const matches = createBreakpoints(breakpoints);

  createEffect(() => {
    console.log(matches.sm); // true when screen width >= 640px
    console.log(matches.lg); // true when screen width >= 1024px
    console.log(matches.xl); // true when screen width >= 1280px
  });

  return (
    <div
      classList={{
        "text-tiny flex flex-column": true, // tiny text with flex column layout
        "text-small": matches.sm, // small text with flex column layout
        "text-base flex-row": matches.lg, // base text with flex row layout
        "text-huge": matches.xl, // huge text with flex row layout
      }}
    >
      <Switch fallback={<div>Smallest</div>}>
        <Match when={matches.xl}>Extra Large</Match>
        <Match when={matches.lg}>Large</Match>
        <Match when={matches.sm}>Small</Match>
        {/* 
          Instead of fallback, you can also use `!matches.sm`
          <Match when={!matches.sm}>Smallest</Match>
         */}
      </Switch>
    </div>
  );
};

Working Demo

createPrefersDark

Provides a signal indicating if the user has requested dark color theme. The setting is being watched with a Media Query.

How to use it

import { createPrefersDark } from "@solid-primitives/media";

const prefersDark = createPrefersDark();
createEffect(() => {
  prefersDark(); // => boolean
});

Server fallback

createPrefersDark accepts a serverFallback argument — value that should be returned on the server — defaults to false.

const prefersDark = createPrefersDark(true);
// will return true on the server and during hydration on the client
prefersDark();

usePrefersDark

This primitive provides a shared root variant that will reuse the same signal and media query across the whole application.

import { usePrefersDark } from "@solid-primitives/media";

const prefersDark = usePrefersDark();
createEffect(() => {
  prefersDark(); // => boolean
});

Note: usePrefersDark will deopt to createPrefersDark if used during hydration. (see issue #310)
