Add .gitignore file #8

Closed github-learning-lab[bot] closed 3 years ago

github-learning-lab[bot] commented 3 years ago

Removing the previous .env file from the branch is great, but it's reactive. We need to ensure future contributions don't include sensitive files by mistake. We can do this by adding a .gitignore file to our repository.

Taking advantage of the .gitignore file

From time to time, there are files you don't want Git to check in to GitHub. You may want to ignore files that contain sensitive credentials or information which should not be pushed to your repository. There are a few ways to tell Git which files to ignore.

Ignoring files

Git uses a file called .gitignore to decide which files and directories to ignore when committing. Keep files containing sensitive data, like configuration or .env files, out of your repositories. This is one way to promote security best practices.

The .gitignore file can, and should, be committed into your repository. By sharing this file and making it part of your code, future contributors to the repository will avoid committing sensitive data. There are many examples of .gitignore files available for you to use in your own repositories. You can find them in the gitignore repository.

Step 10: Add a .gitignore file

In this pull request, I'm adding a .gitignore file. Files ending with .env commonly include sensitive data. This helps you keep files with sensitive data secure and private. Let's add those files to the .gitignore.

:keyboard: Activity: Updating the .gitignore file

  1. Within this pull request, go to Files changed.
  2. Click the ellipsis (...) in the right upper corner and click Edit file to edit the .gitignore file.
  3. Edit the file by adding .env to line 1.

  4. Scroll down, and commit your change.

    Note: Even after adding a file to the .gitignore, the previous commits that have edited that file still exist. If you accidentally committed sensitive data, first change any tokens or passwords. Then, contact GitHub Support for help correcting your history.

This looks great @k-ellen-k, thanks for adding a .env file to the .gitignore. Feel free to add any other file or potential sensitive data to the .gitignore file.

Nice work, @k-ellen-k! Go ahead and delete the branch.

We have one more thing to take care of. Let's go to your next issue here.
