// or, import all modules into a local namespace
import * as hibp from 'hibp';

The following modules are available:

• breach
• breachedAccount
• breachedDomain
• breaches
• dataClasses
• latestBreach
• pasteAccount
• pwnedPassword
• pwnedPasswordRange
• search
• stealerLogsByEmail
• stealerLogsByEmailDomain
• stealerLogsByWebsiteDomain
• subscribedDomains
• subscriptionStatus

Please see the API reference for more detailed usage information and examples.

Quick-Start Example

import { search } from 'hibp';

async function main() {
  try {
    const data = await search('someAccountOrEmail', { apiKey: 'my-api-key' });
    if (data.breaches || data.pastes) {
      // Bummer...
      console.log(data);
    } else {
      // Phew! We're clear.
      console.log('Good news — no pwnage found!');
    }
  } catch (err) {
    // Something went wrong.
    console.log(err.message);
  }
}

void main();

Rate Limiting

The haveibeenpwned.com API rate limits requests to prevent abuse. In the event you get rate limited, the module will throw a custom RateLimitError which will include a retryAfterSeconds property so you know when you can try the call again (as a number, unless the remote API did not provide one, in which case it will be undefined - but that should never happen).

Using in the browser

You have a couple of options for using this library in a browser environment:

• Bundled

  The most efficient and recommended method is to bundle it with client-side code using a module bundler, most likely dictated by your web application framework of choice.

• ESM for Browsers

  Alternatively, you can also import the library directly in your HTML via <script type="module"> tags in modern browsers. The pre-bundled module is available through the unpkg CDN, but you must specify the full path (including the file extension). It's also strongly recommended to include the exact version number as well, otherwise the latest tag will be used, which could be dangerous if/when there are breaking changes made to the API. See unpkg for details and advanced version specification, but you will probably want to do the following (replacing x.y.z with the version you want):

  <script type="module">
    // Replace x.y.z with the desired hibp version      ↓ ↓ ↓
    import { dataClasses } from 'https://unpkg.com/hibp@x.y.z/dist/browser/hibp.module.js';
  
    const logDataClasses = async () => {
      console.table(await dataClasses());
    };
  
    logDataClasses();
  </script>
