When I create an Angular Project, npm download and install a lot of files and folders I end up with a sub-folder named: node_modules <- it is BIG 400+ MB I want to copy this project to another location or save my work off the Lab Machine on Friday I do this.... I delete the node_modules (saving 400+MB of space) copy the project folder somewhere then open a Command Prompt to the new locations and run: npm install it will download and create the folder/files for me -------------------------------------------------- I have the source code the sample projects from the Book to run these project, I open a Command Prompt to the folder and run: npm install followed by npm start ------------------------------------------------------ when it comes time to deploy my application the packge.json tells the deployer what is required to run vs. to develop
