How to fix ".gitignore not working" issue?

Sometimes git does not exclude files/folders added .gitignore especially if you had commited them before. Here is how to fix it. I am ignoring node_modules from Angular project as an example

1. Update .gitignore with the folder/file name you want to ignore. You can use anyone of the formats mentioned below (prefer format1)

### Format1  ###
node_modules/

Hiding Secret Keys for your NodeJS app with Bash

GitHub is a great place to pubslish your code; and it is often required to post code there when learning to code. If you are writing a NodeJS app and being required to publish code to GitHub you should be careful of pushing any code that contains secret API keys. These keys could be scraped and used to write apps with your keys.

tl;dr

Don't have time to read all the stuff below. I get it. Add:

export KEY=value
export ANOTHER_KEY=anothervalue
