Making a new app #

Ruby on Rails is a fantastic back-end framework. As mentioned in my last blog I started learning it last year, and one of the main resource that helped me was the greatly written rails tutorial. But I still faced some issues while setting up a new app, so this is just a reminder for future me and maybe also to someone new to rails. I will also discuss containing gems locally.
To create a new Ruby on Rails app and run it

1. First of all run rails new name-of-the-app
2. To change active directory simply write cd name-of-the-app
3. Install all required gems bundle install
4. Run server with bin/rails server or bin/rails s

Now if you want to use webpacker instead of sprockets, what should you do?
Well, try using --webpack flag with rails new as mentioned in webpacker documentation.
And if you are like me and it did not work for you, just simply change your Gemfile to add it manually or simply write gem add webpacker. After that bin/rails webpacker:install will install webpacker.
You can also set bundle install to some local directory with bundle config path 'path/to/dir' --local to save space or handle gems without worrying about global gem versions.
