Tailwind CSS plugin to generate shorthands for light mode and dark mode colour classes.
Deployment: https://tailwind-dark-aware.vercel.app
Source: https://github.com/joulev/tailwind-dark-aware/tree/main/demo
npm install -D tailwind-dark-aware
Then add the plugin in your tailwind.config.js
file:
module.exports = {
theme: {
// ...
},
plugins: [
require("tailwind-dark-aware"),
// or if you want to call with options:
require("tailwind-dark-aware")({
// your options here
}),
// ...
],
};
This plugin generates classes such as text-daw-red-700
and border-x-daw-emerald-200
that sets the colour dynamically in light mode and dark mode. The light mode version is the one you specify, while the dark mode is the opposite one in the same palette. Essentially, text-daw-red-700
is equivalent to text-red-700 dark:text-red-300
and border-x-daw-emerald-200
is equivalent to border-x-emerald-200 dark:border-x-emerald-800
.
Now you know how to use it: simply add daw
(short for "dark aware") before the colour part of any Tailwind colour utility you use.
// = bg-stone-100 dark:bg-stone-900 text-stone-900 dark:text-stone-100
() => <body className="bg-daw-stone-100 text-daw-stone-900">Hello world</body>;
A couple of things to note:
-
If you provide colour labeled with
DEFAULT
, by default your colour is kept intact (i.e. same colour in dark mode as in light mode). You can change this behaviour.// tailwind.config.js { theme: { extend: { colors: { red: { DEFAULT: "#ff0000", }, }, }, } } // Component.jsx () => <div className="text-daw-red" /> // = text-red dark:text-red
-
If you provide a custom value (using the bracket notation), by default your colour is inverted with
(h, s, l) => (h, s, 100 - l)
. You can choose to keep it intact instead.() => <div className="text-daw-[#123456]" />; // = text-[#123456] dark:text-[#a9cbed]
First of all, you need to call the plugin the way that Tailwind will expect options.
module.exports = {
theme: {
// ...
},
plugins: [
require("tailwind-dark-aware")({
// your options here
}),
// ...
],
};
TypeScript type: string
Default: daw
This sets the suffix added to all colour utilities.
require("tailwind-dark-aware")({ suffix: "my-suffix" })
() => <div className="text-my-suffix-red-300" /> // = text-red-300 dark:text-red-700
TypeScript type: string[]
Default: []
The "shades" to be ignored.
To find the dark mode variant of a colour, tailwind-dark-aware
sorts the palette by luminosity, then get the colour placed opposite to the colour in question.
With the default configuration ([]
), this would mean [50, 950]
, [100, 900]
, [200, 800]
, [300, 700]
and so on. However, if you change it to (say) ["50"]
, the pairing would become [100, 950]
, [200, 900]
, [300, 800]
, etc. Therefore, you would probably not want to use this option.
require("tailwind-dark-aware")({ ignoredKeys: ["400", "700"] })
// 50, 100, 200, 300, 500, 600, 800, 900, 950
() => <div className="text-daw-red-300" /> // = text-red-300 dark:text-red-600
Note: The colour schemes of Tailwind is updated with the 950 shade in Tailwind v3.3.0. If you use an earlier Tailwind version, while the package would still work, since shade 950 is not available you should configure
ignoredKeys
to be["50"]
, otherwise the pairing would be[50, 900]
,[100, 800]
, etc. which is likely not what you want.
TypeScript type: boolean
Default: true
Whether to invert custom colours (provided by the bracket notation) or not. If set to true
, the colour is inverted by "inverting" the luminosity while keeping the hue and saturation.
require("tailwind-dark-aware")({ invertCustomColours: true })
() => <div className="text-daw-[#123456]" /> // = text-[#123456] dark:text-[#a9cbed]
require("tailwind-dark-aware")({ invertCustomColours: false })
() => <div className="text-daw-[#123456]" /> // = text-[#123456] dark:text-[#123456]
TypeScript type: boolean
Default: false
Whether to invert colour defined with DEFAULT
key in tailwind.config.js
. If set to true
, the colour is inverted by "inverting" the luminosity while keeping the hue and saturation.
// tailwind.config.js
{
theme: {
extend: {
colors: {
primary: {
DEFAULT: "#123456",
},
},
},
}
}
require("tailwind-dark-aware")({ invertDefaultColours: true })
() => <div className="text-daw-primary" /> // = text-primary dark:text-[#a9cbed]
require("tailwind-dark-aware")({ invertDefaultColours: false })
() => <div className="text-daw-primary" /> // = text-primary dark:text-primary
TypeScript type: "same-dark" | "no-dark"
Default: "same-dark"
Specify what happens if a colour, either a DEFAULT
colour or a custom colour, is not inverted.
same-dark
means the declaration is also made for dark mode.
require("tailwind-dark-aware")({ nonInvertBehaviour: "same-dark" })
() => <div className="text-daw-primary" /> // = text-primary dark:text-primary
no-dark
does not declare for dark mode.
require("tailwind-dark-aware")({ nonInvertBehaviour: "no-dark" })
() => <div className="text-daw-primary" /> // = text-primary
