hibp

An unofficial TypeScript SDK for Troy Hunt’s Have I been pwned? service.

Installation

In Node.js:

npm install hibp

In Deno:

// Replace x.y.z with the desired hibp version
import * as hibp from 'npm:hibp@x.y.z';

See the browser section below for information on how to use it in the browser.

Features (🔑 = requires an API key)

Get a single breach event
Get all breaches for an account 🔑
Get all breach events in the system
Get all data classes
Get all pastes for an account 🔑
Securely check a password to see if it has been exposed in a data breach
Check a SHA-1 or NTLM prefix to see if it has been exposed in a data breach
Search for an account in both breaches and pastes at the same time 🔑
Get your subscription status 🔑
All queries return a Promise
Available server-side (Node.js) and client-side (browser)
Written in TypeScript, so all modules come fully typed

Usage

ECMAScript module syntax:

// import individual modules as needed
import { dataClasses, search } from 'hibp';
// or, import all modules into a local namespace
import * as hibp from 'hibp';

CommonJS module syntax:

// require individual modules as needed
const { dataClasses, search } = require('hibp');
// or, require all modules into a local namespace
const hibp = require('hibp');

The following modules are available:

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);
  }
}

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 several 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 like webpack or, more likely, whatever your framework of choice uses under the hood.
UMD

There is also a Universal Module Definition (UMD) build provided for usage in the browser. When using this build, an hibp object will be added to the browser’s window object.

The recommended way to include the UMD build (when using a <script> tag) is to use the unpkg CDN, specifying the exact version you want. If you don’t specify a version, 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 generally you will want to do the following (replacing x.y.z with the version you want):
```
<script src="https://unpkg.com/hibp@x.y.z"></script>
```
ESM for Browsers

Modern browsers now support importing ECMAScript modules via <script type="module"> tags. Like the UMD option above, this build is also available the unpkg CDN (and the same versioning rules apply), but you must specify the full path (including the file extension). For example:
```
<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>
```
