Building for use
Dark Reader build script requires a JavaScript runtime, either NodeJS or Deno. We recommend using NodeJS, Deno support is experimental.
Building with NodeJS
You can install the extension from a file. Install Node.js (we recommend LTS or higher, but any version at or above 15 will work). Download the source code (or check out from git). Open the terminal in the root folder and run:
npm installnpm run buildornpm run build [-- flags]
This will create a build/release/darkreader-chrome.zip file for use in a Chromium-based browser and a build/release/darkreader-firefox.xpi file for use in Firefox.
You can customize build process by passing flags to build script. To see all flags, run npm run build -- --help.
Building with Deno
You can build Dark Reader with alternative runtime called Deno. For this run deno:bootstrap script (e.g., via npm run deno:bootstrap or manually copy the command from package.json). Then run the same commands described above.
Please note that if you encounter error Too many open files (os error 24), then you should use the newer version of Deno (preferably built from source or canary).
Bundling with official Firefox store signatures (Experimental)
Prior to publication, extension stores provide digital signatures for extensions. These digital signatures certify the integrity of the archive (that extension bundle did not get corrupted or bit-rotted) and that extension store preformed very basic extension validation.
Dark Reader repository contains these digital signatures and you can add them to the extension bundle. The following will build Dark Reader for Firefox version 4.9.63:
npm run build -- --firefox --version=4.9.63Please note that only Firefox Add-ons store signatures are present in the repositiry right now. Also, due to NodeJS and TypeScript version compatibility, one might have to first check out the old revision (commit), then build the extension files, then check out the recent commit and create the bundle (by running only signature and zip steps).
Using Dark Reader for a website
You can use Dark Reader to enable dark mode on your website!
- Install the package from NPM (
npm install darkreader) - or build from the source code (
npm run api) - or include the script via a CDN such as unpkg or jsDelivr
Then you can use the following code to control Dark Reader's API:
DarkReader.enable({
brightness: 100,
contrast: 90,
sepia: 10
});
DarkReader.disable();
// Enable when the system color scheme is dark.
DarkReader.auto({
brightness: 100,
contrast: 90,
sepia: 10
});
// Stop watching for the system color scheme.
DarkReader.auto(false);
// Get the generated CSS of Dark Reader returned as a string.
const CSS = await DarkReader.exportGeneratedCSS();
// Check if Dark Reader is enabled.
const isEnabled = DarkReader.isEnabled();... or if you are using ES modules:
import {
enable as enableDarkMode,
disable as disableDarkMode,
auto as followSystemColorScheme,
exportGeneratedCSS as collectCSS,
isEnabled as isDarkReaderEnabled
} from 'darkreader';
enableDarkMode({
brightness: 100,
contrast: 90,
sepia: 10,
});
disableDarkMode();
followSystemColorScheme();
const CSS = await collectCSS();
const isEnabled = isDarkReaderEnabled();Be aware that Dark Reader will add the chrome object onto the window object. These are to stub certain functions that the code will use. They originate from the webextension-api.
Site fixes
Automatically syncing the site fixes to every Dark Reader user was disabled because the GitHub team does not allow using GitHub as a CDN. The storage of these files would be expensive, and making requests to other resources would look suspicious. Each new release of Dark Reader will include these changes.
However, this can be enabled using the following steps:
- Click on the Dark Reader icon.
- Click on the Dev tools button (in the bottom-right corner).
- Click on the Preview new design button.
- Enable the
Synchronize site fixessetting underSettings -> Manage Settings.
To force a synchronization of the sites fixes (when the corresponding setting is enabled), perform the following steps:
- Click on the Dark Reader icon.
- Click on the Dev tools button (in the bottom-right corner).
- Click on the Reset button. This will remove any custom site fixes you may have.
