Git staging area

As explained in Build Python Web Apps with Streamlit

A Git staging area is an intermediate snapshot area where selected file changes are prepared before being committed.

The staging area is a temporary holding place where selected changes are assembled into an exact snapshot before committing them to a local Git repository. section 5.2.2

Use the staging area in this deployment workflow:

  • Initialize the project directory as a local Git repository with git init. section 5.2.2
  • Run git add . to place the current project files into the staging area. section 5.2.2
  • Run git commit with a descriptive message to save the staged snapshot locally. section 5.2.2

Preparing a to-do app

For a project containing todo_list.py and task.py, git add . prepares both files for one commit, such as git commit -m "Commit Streamlit to-do list app". The resulting snapshot can then be pushed to GitHub. section 5.2.2

git add .

How Build Python Web Apps with Streamlit covers it

How deep it goes
Defines the staging area and demonstrates its command-line workflow, but does not explain Git’s internal data structures.
Examples
Uses a Streamlit to-do list containing todo_list.py and task.py, staged with git add . before committing.
What you can do after
Operate/configure a Git workflow that stages project files, commits a snapshot, and prepares code for GitHub.
How it connects
Connects the staging area to Git repositories, commits, and remote repositories on GitHub.
