Simple and efficient way to add vocabulary to Anki through AnkiConnect (using dmenu for input)

anki-english-vocabulary.sh

#!/usr/bin/sh 

# CONSTANTS
deck_name="deck name"
card_type_name="card type name"
anki_server="http://localhost:8765/"

front_part=$(dmenu -p "Word: " < /dev/null)
front_part_escaped=$(printf '%s\n' "$front_part" | sed 's/"/\\"/g')
# if either of them is empty, exit 
if [ -z "$front_part_escaped" ]; then
    exit 0
fi

back_part=$(dmenu -p "Definition: " < /dev/null)
back_part_escaped=$(printf '%s\n' "$back_part" | sed 's/"/\\"/g')
# if either of them is empty, exit 
if [ -z "$back_part_escaped" ]; then
    exit 0
fi

curl $anki_server -X POST -H 'Content-Type: application/json' \
     -d '{
