Add all lines from a .env file to environment

zsh:

zsh ./configs/dev/dev.env|sed 's/#1.*$//g'|grep '^[^#]'|grep -v '^$'|sed 's/^/export /g'

1	zsh ./configs/dev/dev.env\|sed 's/#1.*$//g'\|grep '^[^#]'\|grep -v '^$'\|sed 's/^/export /g'

bash:

bash ./configs/dev/dev.env|sed 's/#1.*$//g'|grep '^[^#]'|grep -v '^$'|sed 's/^/export /g'

1	bash ./configs/dev/dev.env\|sed 's/#1.*$//g'\|grep '^[^#]'\|grep -v '^$'\|sed 's/^/export /g'

to output to stdout

cat ./configs/dev/dev.env|sed 's/#1.*$//g'|grep '^[^#]'|grep -v '^$'|sed 's/^/export /g'

1	cat ./configs/dev/dev.env\|sed 's/#1.*$//g'\|grep '^[^#]'\|grep -v '^$'\|sed 's/^/export /g'

prepend running a command (did not try it, but something similar):

env $(cat ./configs/dev/dev.env|sed 's/#.*$//g'|grep '^[^#]'|grep -v '^$'|xargs)

1	env $(cat ./configs/dev/dev.env\|sed 's/#.*$//g'\|grep '^[^#]'\|grep -v '^$'\|xargs)

And if you want to replace some legacy API with your new implementation without breaking backward compatibility, you need to fix it. There could be different ways …
