[![npm version][npm-image]][npm-url] [![Build Status][ci-image]][ci-url]

A [Gatsby][gatsby] plugin to prevent a flash of default styles when using the [use-dark-mode][udm]
hook if the user is not using the default theme. Specifically, this plugin handles the injection of
the [noflash.js][udm-noflash] logic.

Install

``sh
npm install gatsby-plugin-use-dark-mode use-dark-mode
`

Usage

Add the plugin to your gatsby-config.js.


`js
module.exports = {
plugins: [
'gatsby-plugin-use-dark-mode',
],
};
`

Follow the [use-dark-mode][udm] documentation for further instructions.

$3

If you would like to change the class names that are applied, specify the storage key, or skip the
script minification process, you may do so through plugin options:

`js
// gatsby-config.js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-use-dark-mode',
options: {
classNameDark: 'dark-mode',
classNameLight: 'light-mode',
storageKey: 'darkMode',
minify: true,
},
},
],
};
`

> Note: You will also need to pass the corresponding [options to useDarkMode][udm-parameters].

Limitations

[useDarkMode][udm] can be [configured][udm-parameters] to specify which DOM element receives the
class and to use an alternate storage provider if desired. This plugin does not currently support
those options, so it will only work if you are using the defaults (document.body and
localStorage`).
