I'm somewhat new applications with ionic and very new to the subject of the repositories, when I do a commit endless files are uploaded that I find it very difficult to identify what are the changes in the project, that's why I wanted ask for help here, if I can guide you ignore files, if a file exists by default to occupy and where, since most of the work is done in the www folder. Sorry if the question is very basic but I would serve far solve this problem.
The problem here is that if you already add all those files, once you put the .gitignore it will not work as you want. You need to put the .gitignore at the very beginning of your project.
So, my advise: make another project in Git, just upload your project again and create the .gitignore file. I am telling you this based on my own experience.
The basics of what you should put in that .gitignore
node_modules
.tmp
.sass-cache
**/bower_components or sometimes it is lib/**
platforms
plugins
*.swp
*.swo
*.log
*.DS_Store
in order to create this file, you can do it from Git, or from your terminal:
$ touch .gitignore to create a .gitignore file.You can use this gitignore
node_modules/
temp/
*.DS_Store
*.log
*.swp
