Issue

License checking output is quite verbose atm, for example:

https://github.com/fastify/fastify-helmet/runs/7727727775?check_suite_focus=true

The output is:

├─ @fastify/helmet@9.1.0
│  ├─ licenses: MIT
│  ├─ repository: https://github.com/fastify/fastify-helmet
│  ├─ publisher: Matteo Collina
│  ├─ email: hello@matteocollina.com
│  ├─ path: /home/runner/work/fastify-helmet/fastify-helmet
│  └─ licenseFile: /home/runner/work/fastify-helmet/fastify-helmet/LICENSE
├─ fastify-plugin@4.1.0
│  ├─ licenses: MIT
│  ├─ repository: https://github.com/fastify/fastify-plugin

│  └─ licenseFile: /home/runner/work/fastify-helmet/fastify-helmet/node_modules/fastify-plugin/LICENSE
└─ helmet@5.1.1
   ├─ licenses: MIT
   ├─ repository: https://github.com/helmetjs/helmet
   ├─ publisher: Adam Baldwin
   ├─ email: adam@npmjs.com
   ├─ url: https://evilpacket.net/
   ├─ path: /home/runner/work/fastify-helmet/fastify-helmet/node_modules/helmet
   └─ licenseFile: /home/runner/work/fastify-helmet/fastify-helmet/node_modules/helmet/LICENSE

Obviously @fastify/helmet is one of the smaller plugins, this is a lot longer for something like @fastify/swagger or @fastify/static.

If we add the --summary option to license-checker then it'd cut it down to:

└─ MIT: 2

It still throws errors even with this option enabled, so we'll still catch unacceptable licenses, we just won't have to scroll through the long output to get to it.

Can you show the result of error when --summary is used?

Can you show the result of error when --summary is used?

Sure, it's the same as if not using --summary, as an example from fastify-nextjs:

Package "caniuse-lite@1.0.30001373" is licensed under "CC-BY-4.0" which is not permitted by the --onlyAllow flag. Exiting.

Yes, use the less verbose one.
