How to use

// In your gatsby-config.js
plugins: [
        resolve: `gatsby-theme-ghost-dark-mode`,
        options: {
            // Set to true if you want your theme to default to dark mode (default: false)
            // Note that this setting has an effect only, if
            //    1. The user has not changed the dark mode
            //    2. Dark mode is not reported from OS
            defaultModeDark: false,
            // If you want the defaultModeDark setting to take precedence
            // over the mode reported from OS, set this to true (default: false)
            // Note that user choice still takes precedence over this setting
            overrideOS: false,


This Gatsby theme plugin hooks into the gatsby-theme-try-ghost theme and adds a dark mode toggle in the top right navigation bar. User’s dark mode settings are persisted to localStore, so they should remain on page revisits. If the functionality is provided by the browser, dark mode setting is read from the OS and that setting is taken for first time use. The defaultModeDark setting is taken, if OS does not report dark mode or if the user has not chosen a theme preference in the OS. Finally, OS settings can be overruled with overrideOS.

This plugin also shows how to best customize gatsby-theme-try-ghost. The latent-component-shadowing approach used here is very general and is an amazing concept. This is useful if you plan on customizing gatsby-theme-try-ghost yourself.


If you use PrismJS your prism styles might be changed. Currently, the best option is to use a dark PrismJS style that looks great in both dark and light mode.
