An alternative package manager for Node.

• blazingly fast due to completely concurrent installation procedure and constant (micro) optimizations
• correctly resolves (circular) dependencies
• supports semver
• correctly handles devDependencies
• produces a flat node_modules directory
• verifies the integrity of downloaded packages
• fast caching
• interfaces with the npm registry
• has no global namespace for packages
• allows you to require multiple versions of the same package
• visually indicates progress via progress bar
• respects your global configuration
• can run arbitrary scripts defined in your package.json (e.g. test)
• supports the usual install flags, such as --save, --save-dev
• allows you to install arbitrary groups of packages, e.g. (ied install --only otherDeps, ied install --only prod)
• useful utilities, such as ping, config, ls
• allows you to easily start a new sub-shell that allows you to use the scripts exposed by your dependencies without installing them globally via ied sh
• supports private registries
• makes it impossible for you to accidentally require sub-dependencies, even though node_modules is completely flat
• completely atomic: node_modules is guaranteed to be consistent

The original idea was to implement npm's pre-v3 install algorithm in as few lines as possible. This goal was achieved in c4ba56f.

Currently the main goal of this project is to provide a more performant alternative to npm. I like npm, but it's just too slow.

The easiest way to install ied is using npm:

  npm i -g ied

Alternatively you can also "bootstrap" ied. After an initial installation via npm, ied will install its own dependencies:

  git clone https://github.com/alexanderGugel/ied ied && cd $_ && make install

  ied is a package manager for Node.

  Usage:

    ied command [arguments]

  The commands are:

    install     fetch packages and dependencies
    run         run a package.json script
    test        run the test-suite of the current package
    shell       enter a sub-shell with augmented PATH
    ping        check if the registry is up
    ls          print the dependency graph
    expose      make a sub-dependency `require`able
    config      print the used config
    init        initialize a new package

  Flags:
    -h, --help      show usage information
    -v, --version   print the current version
    -S, --save      update package.json dependencies
    -D, --save-dev  update package.json devDependencies
    -o, --only      install a subset of the dependencies
    -r, --registry  use a custom registry (default: http://registry.npmjs.org/)

  Example:
    ied install <pkg>
    ied install <pkg>@<version>
    ied install <pkg>@<version range>

    Can specify one or more: ied install semver@^5.0.1 tape
    If no argument is supplied, installs dependencies from package.json.
    Sub-commands can also be called via their shorthand aliases.

Some ideas and (upcoming) features of ied are heavily inspired by Nix, a purely functional package manager.

• What does ied stand for?

  Nothing in particular. It's just easy to type and mpm (the original name) was already taken.
