Create a .gitignore file in the git repository if it does not contain one
touch .gitignore
-- Open up the .gitignore and add the following line to the file
.gitignore
node_modules
-- Remove the node_modules folder from the git repository
git rm -r --cached node_modules
-- Commit the git repository without the node modules folder
git commit -m "Removed node_module folder"
-- Push the repository to github
git push origin master
Thanks!
