# TypeScript client SCRAM authentication library

This library is used by clients wanting to authenticate with servers that use SCRAM (Salted Challenge Response Authentication Mechanism).

For more information on SCRAM, please see the [specification](https://datatracker.ietf.org/doc/html/rfc5802#page-8).

## Installation

    npm install @j2inn/scram

## Use

    import authenticate from '@j2inn/scram'

    ...

    async function onAuthenticate(username: string, password: string): void {
      await authenticate({
        username,
        password,
        uri: new URL('/auth', window.location.href)
      })
    }

An alternative `fetch` parameter can be specified if this library is used in a NodeJS environment...

    import fetch from 'node-fetch'
    import authenticate from '@j2inn/scram'

    ...

    async function onAuthenticate(username: string, password: string, uri: string): void {
      await authenticate({
        username,
        password,
        fetch,
        uri
      })
    }
