Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including detect-external-link. Try it out:
const detectExternalLink = require('detect-external-link').default;
const link = 'http://test.example2.com/test/abc/';
const linkOptions = {
'hosts': [
'http://example.com',
'http://test.example.com'
]
};
console.log(detectExternalLink(link, linkOptions));
