serviceberry-basic-auth

Basic HTTP Authentication plugin for Serviceberry.

Install

npm install serviceberry-basic-auth

Usage

This plugin exports an abstract class BasicAuth for extending by your authorization class that know how to fetch your password hashes. To use this plugin extend BasicAuth and implement at least getHash(username). The resulting hash is expected to be a bcrypt hash. getHash can be an async function explicitly or it can return promise or synchronously return the hash.

const BasicAuth = require("serviceberry-basic-auth");

class Auth extends BasicAuth {
	getHash (username) {
		return data.getHash(username); // can also return a promise or use async/await
	}
}

trunk.use(new Auth("Secret Realm"));

BasicAuth

Abstract class

constructor(realm[, charset])

• realm string

  Identifies the protection space to the client when the server asks for credentials. Sets this.realm. Realm can contain curly brackets which delimit placeholder names which correlate to path parameters. For example {tenant}'s realm would result in bob's realm when the value of the value of the path parameter tenant is bob.

  From RFC 7617

  ...a free-form string that can only be compared for equality with other realms on that server.

• charset

  The character set that the server expects the client to use when sending the credentials. Defaults to UTF-8. Sets this.charset.
