Tips

Update to the latest npm version

$ npm install --global npm

Command aliases

  • npm i → npm install
  • npm i -S → npm install --save
  • npm i -D → npm install --save-dev
  • npm t → npm test
  • npm it → npm install && npm test
  • npm r → npm uninstall

Shell aliases

Speed up your common npm tasks.
In your .zshrc/.bashrc:
alias ni='npm install'
alias nis='npm install --save'
alias nid='npm install --save-dev'
alias nig='npm install --global'
alias nt='npm test'
alias nit='npm install && npm test'
alias nk='npm link'
alias nr='npm run'
alias nf='npm cache clean && rm -rf node_modules && npm install'

Add to package.json when installing

You can have npm add packages to package.json when installing by specifying the --save/-S flag for dependenciesand --save-dev/-D for devDependencies:
$ npm install --save chalk

Run scripts

You can easily run scripts using npm by adding them to the "scripts" field in package.json and run them with npm run <script-name>. Run npm run to see available scripts. Binaries of locally install packages are made available in the PATH, so you can run them by name. npm run foo will also run prefoo and postfoo if defined.
{
    "name": "awesome-package",
    "scripts": {
        "cat": "cat-names"
    },
    "dependencies": {
        "cat-names": "^1.0.0"
    }
}
$ npm run cat
Max
All package.json properties are exposed as environment variables:
{
    "name": "awesome-package",
    "scripts": {
        "name": "echo $npm_package_name"
    }
}
$ npm run name
awesome-package

Link local packages

Sometimes it can be useful to have a local version of a package as a dependency. You can use npm link to link one local package into another. Run npm link in the package you want to use. This creates a global reference. Then go into your original package and run npm link <package-name> to link in the other package.
$ cd rainbow
$ npm link
$ cd ../unicorn
$ npm link rainbow
You can now use rainbow as a dependency in the unicorn package.

Install a package from GitHub

npm supports using a shorthand for installing a package directly from a GitHub repo:
$ npm install sindresorhus/chalk
Let's target a specific commit as master is a moving target:
$ npm install 'sindresorhus/chalk#51b8f32'
Specify either a commit SHA, branch, tag, or nothing.

Install a specific version of a package

$ npm install chalk@1.0.0

List top-level installed packages and their version

$ npm ls --depth=0

Command help

Get help docs for a command:
$ npm help <command>
Example:
$ npm help install

Standalone version of a package

Quickly get a standalone version of a package that is browserified and usable in the browser.
https://wzrd.in/standalone/<package-name>[@<version>]
Examples:
Great for prototyping, but download the file or use Browserify yourself for production.
