Having Python 3.8 or above installed.
To build debug copy for both Chrome and Firefox, simply run the following command:
python build.py
This will create a dist directory in the project root directory, in which you will find firefox and chrome directories for debugging purposes. If you use the -p argument, each debugging directory will have an additional xpi/crc archive for production usage.
For development convenience, build.py also supports listening to changes so files are quickly updated.
For that, you need to install python's watchdog in your machine:
python -m pip install watchdog
Then you can run build.py command with the -w option so your changes immediately apply:
python build.py -w
or
./build.py -w
npm install uglify-js -g
python build.py -p
Note: The watchdog option -w is also supported here: (python build.py -pw)
Minified code for production can be found in the .zip files in the corresponding browser directory. The zip files can be used for final testing/debugging before sending them to the webstores.
