npm install without sudo

Install npm packages globally without sudo on macOS and Linux

npm installs packages locally within your projects by default. You can also install packages globally (e.g. npm install -g <package>) (useful for command-line apps). However the downside of this is that you need to be root (or use sudo) to be able to install globally.

Here is a way to install packages globally for a given user.

1. Create a directory for global packages
mkdir "$HOME/.npm-packages"
2. Indicate to npm where to store globally installed packages. In your ~/.npmrc file add:
prefix=$HOME/.npm-packages
3. Ensure npm will find installed binaries and man pages. Add the following to your .bashrc/.zshrc:
PATH="$PATH:$HOME/.npm-packages/bin"
