npminstall

Make npm install fast and handy.

Node.js and Python required

Node.js >= 14.x
Python >= 3.x

Use as Cli

Install

$ npm install npminstall -g

Usage

In cnpm

It is integrated in cnpm.

$ npm install cnpm -g
# will use npminstall
$ cnpm install

npminstall

Usage:

  npminstall
  npminstall <pkg>
  npminstall <pkg>@<tag>
  npminstall <pkg>@<version>
  npminstall <pkg>@<version range>
  npminstall <alias>@npm:<name>
  npminstall <folder>
  npminstall <tarball file>
  npminstall <tarball url>
  npminstall <git:// url>
  npminstall <github username>/<github project>

Can specify one or more: npm install ./foo.tgz bar@stable /some/folder
If no argument is supplied, installs dependencies from ./package.json.

Options:

  --production: won't install devDependencies
  --save, --save-dev, --save-optional: save installed dependencies into package.json
  -g, --global: install devDependencies to global directory which specified in `$ npm config get prefix`
  -r, --registry: specify custom registry
  -c, --china: specify in china, will automatically using chinese npm registry and other binary's mirrors
  -d, --detail: show detail log of installation
  --trace: show memory and cpu usages traces of installation
  --ignore-scripts: ignore all preinstall / install and postinstall scripts during the installation
  --no-optional: ignore optionalDependencies during the installation
  --forbidden-licenses: forbit install packages which used these licenses
  --engine-strict: refuse to install (or even consider installing) any package that claims to not be compatible with the current Node.js version.
  --flatten: flatten dependencies by matching ancestors dependencies
  --registry-only: make sure that all packages are installed from registry. Any package that is installed from remote(e.g.: git, remote url) will lead to a failure of installation.
  --cache-strict: use disk cache even on production env

npmuninstall

Usage:

  npmuninstall <pkg>
  npmuninstall <pkg>@<version>
  npmuninstall <pkg>@<version> [<pkg>@<version>]

Use as Lib

Install

$ npm install npminstall --save

Usage

const npminstall = require('npminstall');

(async () => {
  await npminstall({
    // install root dir
    root: process.cwd(),
    // optional packages need to install, default is package.json's dependencies and devDependencies
    // pkgs: [
    //   { name: 'foo', version: '~1.0.0' },
    // ],
    // install to specific directory, default to root
    // targetDir: '/home/admin/.global/lib',
    // link bin to specific directory (for global install)
    // binDir: '/home/admin/.global/bin',
    // registry, default is https://registry.npmjs.org
    // registry: 'https://registry.npmjs.org',
    // debug: false,
    // storeDir: root + 'node_modules',
    // ignoreScripts: true, // ignore pre/post install scripts, default is `false`
    // forbiddenLicenses: forbit install packages which used these licenses
  });
})().catch(err => {
  console.error(err);
});

Support Features

Different with NPM

This project is inspired by pnpm, and has a similar store structure like pnpm. You can read pnpm vs npm to see the different with npm.

Limitations

You can't install from shrinkwrap(and don't want to support for now).
Peer dependencies are a little trickier to deal with(see rule 1 below).
You can't publish npm modules with bundleDependencies managed by npminstall(because of rule 2 below).
npminstall will collect all postinstall scripts, and execute them until all dependencies installed.
If last install failed, better to cleanup node_modules directory before retry.

`node_modules` directory

Two rules:

The latest version of modules will link at options.storeDir's node_modules.
Module's dependencies will link at module's node_modules.

e.g.:

app: { "dependencies": { "debug": "2.2.0" } } (root)
[email protected]: { "dependencies": { "ms": "0.7.1" } }

app/
├── package.json
└── node_modules
    ├── [email protected]@debug
    │   ├── node_modules
    │   │   └── ms -> ../../[email protected]@ms
    ├── _ms0.7.1@ms
    ├── debug -> [email protected]@debug
    └── ms -> [email protected]@ms # for peerDependencies

flattened vs nested

npminstall will always try to install the maximal matched version of semver:

root/
  [email protected]
  mod/
    koa@~1.1.0
# will install two different version of koa when use npminstall.

you can enable flatten mode by --flatten flag, in this mod, npminstall will try to use ancestors' dependencies to minimize the dependence-tree.

root/
  [email protected]
  mod/
    koa@~1.1.0

root/
  [email protected]
  mod/
    koa@^1.1.0
# both the same version: 1.1.0

root/
  koa@~1.1.0
  mod/
    koa@^1.1.0
# both the same version: 1.1.2

root/
  mod/
    koa@^1.1.0
  moe/
    koa@~1.1.0
# two different versions

npminstall will always treat n.x and n.m.x as flattened

root/
  [email protected]
  mod/
    [email protected]
both the same version: 1.1.0

root/
  koa@~1.1.0
  mod/
    [email protected]
both the same version: 1.1.2

Resolutions

support selective version resolutions like yarn. which lets you define custom package versions inside your dependencies through the resolutions field in your package.json file.

resolutions also supports [npm alias)(https://docs.npmjs.com/cli/v7/commands/npm-install). It's a workaround feature to fix some archived/inactive/ package by uploading your own bug-fixed version to npm registry.

see use case at unittest package.json.
