How I set up my new Next.js projects with a handy bash script
If you’ve watched my live streams on Twitch, you’ll have seen me speed-build and YOLO-deploy quite a few websites with Next.js.
After I bootstrap a new Next.js application with npx create-next-app, there are several things I do to prepare the app for development, including:
delete the vercel.svg file
delete the Home.module.css file
add my own CSS reset rules to globals.css
add a custom pages/_document.js file to add a lang attribute to the HTML tag to improve accessibility
delete lots of code from pages/index.js
open the new project in VSCode
I’m a big fan of automation, and so I wrote a bash script to take care of these tasks for me — and to remind me to have a nice day 😎.
If you’d like to do the same, run the script below with —lang, —appname and —dir flags — and have a nice day! You can also bookmark the gist on GitHub.
# Input flags
LANG=""
APP_NAME=""
# The directory path must be relative to where the script lives
DIR=""
# Loop through arguments and process them
for arg in "$@"
do
case $arg in
-h|--help)
echo "⚡️ Example script usage ⚡️"
echo "./reset-next.sh --lang=en --appname=\"my cool app\" --dir=this-test"
shift
exit;

LANG="${arg#*=}"
shift
;;
-a=*|--appname=*)
APP_NAME="${arg#*=}"

-d=*|--dir=*)
