After downloading/cloning the repository, run the following commands to get started:
# Install dependencies
npm install
# Build the extension for the default target browser for local development
# See table below for supported targets
npm run build
Once the extension has been built, you can load the unpacked extension (found in dist/
) in your browser.

The state files hold the details about the current build. These files are managed by bin/prebuild.js
.
.build.json
- Active build state file that is referenced when building/packaging/releasing
- Gets replaced by the dev or release build files outlined below
.build.dev.json
- Holds the development build details and allows the developer to omit the target from commands such as
npm run build
to rebuild the project for the target specified in the file - Overwrites

Adding support for a new language can be done by creating a new locale folder (locales/{lang}
) with a file for each namespace. To update an existing translation, modify the existing file in the same location.
Translations will automatically be compiled at build time (part of the prebuild
script), but can be run manually as well with npm run build:translations
. The compiled translations are stored in src/script/translations.js
.
To use the translations, use the Translation
class (src/script/translation.ts
). When creating a new instance, pass in the desired namespace(s) (you should almost always include the 'common'
namespace). Once you have the translation instance you can simply call translation.t()
with the desired key, such as common:app.name
.
