npm-sum

Show brief summary of package information registered on npm.

$ npm i -g npm-sum

Why and What

npm view (or show, info, v) outputs huge raw JSON which contains all information of the package, but, for a human, it's not easy to read and find what one wants to know.

$ npm view npm
{
  "name": "npm",
  "description": "a package manager for JavaScript",
  "dist-tags": {
    "latest": "4.0.2",
    "next": "4.0.3",
    "latest-2": "2.15.11",
    "v3.x-latest": "3.10.9",
    "3.x-latest": "3.10.9",
    "3.x-next": "3.10.10",
    "v3.x-next": "3.10.10",
    "next-2": "2.15.11",
    "latest-1": "1.4.29",
    "lts": "2.15.11",
    "latest-3": "3.10.10",
    "next-3": "3.10.10"
  },
  "versions": [
    "1.1.25",
    "1.1.70",
    "1.1.71",
    "1.2.19",
    "1.2.20",
    "1.2.21",
    ... (more than 1000 lines)
}

npm-sum outputs a summary of the information which includes only the most important ones (as I think).

$ npm-sum npm

How to use

Just like npm view.

$ npm-sum [options] [<@scope>/]<name>[@<version>]

It executes npm as a child process to fetch package information from the registry, and summarizes it into a human readable format.

Options

• --no-dependencies : do not show dependencies
• -h, --help: output help
• -v, --version: output version
