## Features
- Computes the 64-bit AVRO fingerprint for a given AVRO schema string

## Installation

npm install avro-crc64
```

## Documentation
- [API](docs/API.md)

## Examples

```js
const { fingerprint64AvroSchema } = require('avro-crc64');

const avroSchemaExample = {
  type: 'record',
  name: 'Example',
  doc: 'Simple example avro schema',
  fields: [
    {
      name: 'foobar',
      type: 'string',
      doc: 'foobar is all about barbazz',
    },
  ],
};

fingerprint64AvroSchema(JSON.stringify(avroSchemaExample))
  .then((uint8) => {
    const hexFingerprint = Buffer.from(uint8.buffer).toString('hex');

    return console.log(hexFingerprint); // logs "b75d6f7da238cf70"
  })
;```
