Adding js-spice as a git submodule to a host app

Adding the js-spice module to a host application using Git submodules involves a series of steps. Here's a guide to help you through the process:

1 Initialize the Host Application Repository (If Not Already Done):

• If your host application isn't already a Git repository, initialize it with git init.

2 Add the Module as a Submodule:

• Navigate to the root directory of your host application.
• Use the command git submodule add https://github.com/gamergenic/js-spice.git to add your module as a submodule.

3 Specify the Path for the Submodule:

• While adding the submodule, you can also specify a path where you want the submodule to be placed. For instance: git submodule add https://github.com/gamergenic/js-spice.git <desired path>.
• If you don't specify a path, the submodule will be placed in a directory with the same name as the repository by default.

4 Initialize and Update the Submodule:

• Run git submodule init to initialize your submodule.
• Then, run git submodule update to fetch all the data from the submodule project and check out the specified commit in your submodule.

5 Commit the Changes in the Host Application:

• After adding the submodule, you will see changes in your host application's repository. These changes include the addition of the .gitmodules file and the submodule's directory.
• Commit these changes with git add . and git commit -m "Add js-spice as a submodule".

6 Clone the Host Application Along with Submodules:

• If you need to clone the host application repository along with its submodules, use the command git clone --recurse-submodules <repository URL of host application>.

7 Update the Submodule:

• To update the js-spice module to the latest commit available in its repository, navigate to the submodule's directory and run git pull origin master (or the branch you wish to pull from).
• Then, go back to your host application's root directory and commit the changes.

8 Push the Changes to the Host Application Repository:

• After committing the changes, push them to the host application repository with git push. Remember, each submodule is essentially a separate Git repository, so you need to commit and push changes within each submodule separately, as well as in the host repository.

9 Updating the js-spice module to latest from your host app:

cd modules/js-spice
git pull origin main
npm install
