Your framework will provide a command line interface (CLI) that lets you create a new project with a single command. Now, let’s say you are developing a new project and you are using NPM to find and manage your packages. Unfortunately, it also introduced a number of challenges regarding versioning and dependency management. Since its release, Node Package Manager (NPM) has become the de facto standard for distributing most Javascript projects, from servers to frontend frameworks and overall, it has vastly simplified developers lives. Let's say we depend on lodash version ^3.9.2, and we have that version installed under node_modules/lodash.The challenge with NPM versioning When you run npm update, npm checks if there exist newer versions out there that satisfy specified semantic versioning ranges and installs them. Instead of npm install, you can use npm update to freshen already installed packages. ![]() ![]() After the initial install, re-running npm install does not update existing packages since npm already finds satisfying versions installed on the file system. When you run npm install on a fresh project, npm installs the latest versions satisfying the semantic versioning ranges defined in your package.json. Updating to close-by version with npm update ![]() Here's the correct way to update dependencies using only npm from the command line. Semantic versioning screws things just enough, so it's safer to manually edit package.json than to attempt npm acrobatics. It's hard to update a new version of a library.
