I just found one of a dev tool called gitignore.io which as it's name suggests, helps generate a gitignore file for our project.

Web

1. Go to gitignore.io
2. Fill in the languages, IDE's, OS's you're using
3. Click Create
4. Copy Code and paste it into a .gitignore file in your project root

CLI

1. Go to this link
2. Follow instructions based on your os and terminal
3. Go to a project
4. List possibilities for gitignore

   gi list
   

This will list all the possibilities for your .gitignore file that you can choose from

1. Create a .gitignore file Say, I am choosing node, vscode, and macos as my options.

   gi node,vscode,macos >> .gitignore
   

   

And voilà, your .gitignore file has been created!
