Reading and Writing Data Using the NeverBounce API

Hey there, fellow JavaScript wizards! Ready to level up your email validation game? Let's dive into the world of NeverBounce API and see how we can seamlessly integrate it into our user-facing applications. Buckle up!

Setting Up the NeverBounce API

First things first, let's get our hands dirty with some setup. Installing the NeverBounce SDK is a breeze:

npm install neverbounce

Now, let's authenticate and get that API key working:

const NeverBounce = require('neverbounce');

const client = new NeverBounce({ apiKey: 'your_api_key_here' });

Pro tip: Keep that API key safe and sound in your environment variables. No one likes a leaked key, right?

Reading Data from NeverBounce API

Time to put on our detective hats and start investigating those emails. Here's how you can verify a single email:

async function verifySingleEmail(email) {
  try {
    const result = await client.single.check(email);
    console.log(result.outcome);
    return result;
  } catch (error) {
    console.error('Oops!', error);
  }
}

Need to verify a bunch of emails? No sweat! Here's how you can handle bulk verification:

async function verifyBulkEmails(emails) {
  try {
    const job = await client.jobs.create(emails);
    const results = await client.jobs.download(job.job_id);
    return results;
  } catch (error) {
    console.error('Houston, we have a problem:', error);
  }
}

Writing Data to NeverBounce API

Now that we've got reading down, let's flip the script and write some data. Here's how you can submit emails for verification:

async function submitEmails(emails) {
  try {
    const job = await client.jobs.create(emails);
    console.log('Job created:', job.job_id);
    return job;
  } catch (error) {
    console.error('Submission failed:', error);
  }
}

Syncing Data for User-Facing Integration

Real-time verification is where the magic happens. Check this out:

async function realTimeVerification(email) {
  try {
    const result = await client.single.check(email);
    updateUserData(email, result.outcome);
    return result;
  } catch (error) {
    console.error('Verification failed:', error);
  }
}

function updateUserData(email, outcome) {
  // Update your user database with the verification outcome
  console.log(`Updating ${email} with outcome: ${outcome}`);
}

Best Practices for API Usage

Remember, with great power comes great responsibility. Keep an eye on those rate limits and handle errors like a pro:

async function safeApiCall(apiFunction, ...args) {
  const maxRetries = 3;
  let retries = 0;

  while (retries < maxRetries) {
    try {
      return await apiFunction(...args);
    } catch (error) {
      if (error.status === 429) { // Too Many Requests
        await new Promise(resolve => setTimeout(resolve, 1000 * (retries + 1)));
        retries++;
      } else {
        throw error;
      }
    }
  }

  throw new Error('Max retries reached');
}

Performance Optimization

Want to kick things up a notch? Try this optimized bulk verification:

async function optimizedBulkVerification(emails) {
  const batchSize = 1000;
  const results = [];

  for (let i = 0; i < emails.length; i += batchSize) {
    const batch = emails.slice(i, i + batchSize);
    const batchResults = await safeApiCall(verifyBulkEmails, batch);
    results.push(...batchResults);
  }

  return results;
}

Security Considerations

Last but not least, always sanitize that user input:

function sanitizeEmail(email) {
  return email.trim().toLowerCase();
}

And there you have it, folks! You're now armed with the knowledge to read and write data like a pro using the NeverBounce API. Remember, practice makes perfect, so get out there and start validating those emails!

Happy coding, and may your bounce rates be ever in your favor! 🚀
