$ npm i @nodesecure/licenses-conformance
# or
$ yarn add @nodesecure/licenses-conformance
```

## Usage example

```js
import { licenseIdConformance } from "@nodesecure/licenses-conformance";

const result = licenseIdConformance("MIT");
if (result.ok) {
  console.log(result.value);
}
/*  
  {
    uniqueLicenseIds: ["MIT"],
    spdxLicenseLinks: ["https://spdx.org/licenses/MIT.html#licenseText"],
    spdx: {
      osi: true,
      fsf: true,
      fsfAndOsi: true,
      includesDeprecated: false
    }
  }
*/
```

## API

```ts
interface spdxLicenseConformance {
  uniqueLicenseIds: string[];
  spdxLicenseLinks: string[];
  spdx?: {
    osi: boolean;
    fsf: boolean;
    fsfAndOsi: boolean;
    includesDeprecated: boolean;
  };
}

function licenseIdConformance(
  licenseID: string
): { ok: true, value: spdxLicenseConformance } | { ok: false, value: Error };

function searchSpdxLicenseId(contentStr: string): string | null;
```

## Updating SPDX licenses

To update the `src/spdx.json` file just run the following npm script:

```bash
$ npm run spdx:refresh
```

It will fetch SPDX licenses [here](https://github.com/spdx/license-list-data/blob/main/json/licenses.json).
