Better NPM Audit

The goal of this project is to help to reshape npm audit into the way the community would like, by the community itself. Giving another option for everyone and encourage more people to do security audits.

Supports both NPM version 6 and 7

NPM has upgraded to version 7 in late 2020 and has breaking changes on the npm audit. The output of npm audit has significantly changed both in the human-readable and --json output styles. We have added handling so it works properly in both npm versions.

Installation

$ npm install --save better-npm-audit

or

$ npm install -g better-npm-audit

Usage

Run global

better-npm-audit audit

Run with exceptions

Unhandled or newly reported vulnerabilities will be highlighted:

Unused exceptions will be notified:

Add into package scripts

{
  "scripts": {
    "prepush": "npm run test && npm run audit",
    "audit": "better-npm-audit audit"
  }
}

Now you can run locally or in your CI pipeline:

npm run audit

Options

Flag	Short	Description
--exclude	-x	Exceptions or the vulnerabilities ID(s) to exclude
--level	-l	The minimum audit level to validate; Same as the original --audit-level flag
--production	-p	Skip checking the devDependencies
--registry	-r	The npm registry url to use

Environment Variables

Variable	Description
NPM_CONFIG_AUDIT_LEVEL	Used in setting the audit level. Note: this will be disregard if the audit level flag is passed onto the command.

Using .nsprc file to manage exceptions

You may add a file .nsprc to your project root directory to manage the exceptions. For example:

{
  "1337": {
    "active": true,
    "notes": "Ignored since we don't use xxx method",
    "expiry": 1615462134681
  },
  "4501": {
    "active": false,
    "notes": "Ignored since we don't use xxx method"
  },
  "980": "Ignored since we don't use xxx method",
  "Note": "Any non number key will not be accepted"
}

Fields

Attribute	Type	Description	Default	Examples
active	Boolean	If the tool should use it for exception	true	true
expiry	String | Number	Human-readable date, or milliseconds since the UNIX Epoch		- '2020-01-31' - '2020/01/31' - '01/31/2021, 11:03:58' - '1 March 2016 15:00' - '1 March 2016 3:00 pm' - '2012-01-26T13:51:50.417-07:00' - 'Sun, 11 Jul 2021 03:03:13 GMT' - 'Thu Jan 26 2017 11:00:00 GMT+1100 (Australian Eastern Daylight Time)' - 327611110417
notes	String	Notes related to the vulnerability.

When using a .nsprc file, a report will be displayed when it starts running:

Note: the expiry date will be styled in yellow and red color if it is detected more than one or five years ago.
