Examples

Basic URL Detection

const { SharpApiDetectUrlsService } = require('@sharpapi/sharpapi-node-detect-urls');

const service = new SharpApiDetectUrlsService(process.env.SHARP_API_KEY);

const socialPost = `
Check out these awesome resources:
- https://docs.example.com
- www.github.com/username/project
- example.com/api/docs
`;

service.detectUrls(socialPost)
  .then(statusUrl => service.fetchResults(statusUrl))
  .then(result => {
    const urls = result.getResultJson();
    console.log(`Found ${urls.length} URLs:`);
    urls.forEach((url, index) => {
      console.log(`${index + 1}. ${url.url} (${url.protocol})`);
    });
  })
  .catch(error => console.error('Detection failed:', error));

Security-Focused URL Analysis

const service = new SharpApiDetectUrlsService(process.env.SHARP_API_KEY);

const userContent = `
Click here: http://suspicious-site.com
Or visit: https://secure-site.com
`;

const statusUrl = await service.detectUrls(userContent);
const result = await service.fetchResults(statusUrl);
const urls = result.getResultJson();

const insecureUrls = urls.filter(url => !url.is_secure);

if (insecureUrls.length > 0) {
  console.log('⚠️ Warning: Found insecure URLs:');
  insecureUrls.forEach(url => {
    console.log(`  - ${url.url} (${url.protocol})`);
  });
}

Link Extraction from Documents

const service = new SharpApiDetectUrlsService(process.env.SHARP_API_KEY);

const document = `
API Documentation: https://api.example.com/v2/docs
Support Portal: https://support.example.com
Community Forum: https://community.example.com/discussions
`;

const statusUrl = await service.detectUrls(document);
const result = await service.fetchResults(statusUrl);
const urls = result.getResultJson();

const linkDirectory = urls.map(url => ({
  domain: url.domain,
  full_url: url.url,
  secure: url.is_secure
}));

console.log('Extracted Links:', linkDirectory);
