spdx-license-list

> List of SPDX licenses

The lists of licenses are just JSON files and can be used anywhere.

- spdx.json contains just license metadata
- spdx-full.json includes the license text too
- spdx-simple.json only contains the license IDs

Using SPDX License List version 3.27.0 (2025-07-01)

Install

``sh
npm install spdx-license-list
`

Usage

`js
const spdxLicenseList = require('spdx-license-list');

console.log(spdxLicenseList.MIT);
/*
{
name: 'MIT License',
url: 'http://www.opensource.org/licenses/MIT',
osiApproved: true
}
*/
`

`js
const mitLicense = require('spdx-license-list/licenses/MIT');

console.log(mitLicense.licenseText);
//=> 'MIT License\r\n\r\nCopyright (c) …'
`

You can also get a version with the licence text included:

`js
const spdxLicenseList = require('spdx-license-list/full');

console.log(spdxLicenseList.MIT);
/*
{

`
