Ignoring a folder to commit in git

Question

I have an application which I am making

The App as usual have two parts

-> The frontend 
-> The Backend 

Both frontend and Backend are inside parent a folder which I initialised using git init.

ParentFolder 
--> Frontend 
--> Backend
// Git Initialisation is done on Parent folder

Now whenever I add module for frontend and backend and do git add, git commit, it is also committing the node module inside the frontend and backend.

[Question:] So i want git to ignore node modules folder in frontend and backend, So how can I achieve this?

Answer 1

Create a .gitignore file at the root of your project and target any node_modules folder.

.gitignore documentation

A gitignore file specifies intentionally untracked files that Git should ignore. Files already tracked by Git are not affected

---

Structure

Parent folder
   Frontend   (folder)
   Backend    (folder)
  .git        (folder)
  .gitignore  (file)

.gitignore file content

node_modules/

Answer 2

Using a .gitignore file will help you do this.

Considering you have the following structure:

->ParentFolder 
|-->Frontend 
|     |-->node modules
|
|---> Backend
|     |-->node modules

You can use the following lines in the .gitignore file created at the root of your project.

*/node_modules/
