Minify collected javascript files
|
||
|
|
|
||
|
|
This would ideally be moved into either the frontend building pipeline (gulp
|
||
|
|
et al.) or integrated into the building process (collectstatic or another
|
||
|
|
management command).
|
||
|
|
|
||
|
|
To minify your collected javascript files, add the following command at the
|
||
|
|
end of the Dockerfile for your project (after the `</DOCKER_BUILD>` tag):
|
||
|
|
|
||
|
|
# minify collected javascript files
|
||
|
|
# ---------------------------------
|
||
|
|
RUN python tools/minify.py
