passport-strategy

What is passport-strategy?

The passport-strategy package provides an interface for implementing authentication strategies in Node.js applications using the Passport authentication middleware. It is designed to be subclassed by specific strategy implementations, which define how authentication is performed.

What are passport-strategy's main functionalities?

Strategy Interface Creation

This code demonstrates how to create a custom authentication strategy by extending the base Strategy class provided by passport-strategy. Developers can implement their own authenticate method to define the authentication process.

const passport = require('passport-strategy');

class CustomStrategy extends passport.Strategy {
  constructor(verify) {
    super();
    this.name = 'custom';
    this._verify = verify;
  }

  authenticate(req, options) {
    // Custom authentication logic here
  }
}

Other packages similar to passport-strategy

passport-local

Implements a local authentication strategy using a username and password. It is more specific compared to passport-strategy, which is a generic interface for any type of authentication.

passport-oauth2

Implements an OAuth 2.0 authentication strategy, providing mechanisms to authenticate with third-party services. It contrasts with passport-strategy by focusing specifically on OAuth 2.0 protocol.

passport-http

Provides strategies for authenticating with HTTP mechanisms such as Basic and Digest authentication. Unlike passport-strategy, which is a framework, passport-http offers concrete implementations for these HTTP authentication methods.

README

passport-strategy

An abstract class implementing Passport's strategy API.

Install

$ npm install passport-strategy

Usage

This module exports an abstract Strategy class that is intended to be subclassed when implementing concrete authentication strategies. Once implemented, such strategies can be used by applications that utilize Passport middleware for authentication.

Subclass Strategy

Create a new CustomStrategy constructor which inherits from Strategy:

var util = require('util')
  , Strategy = require('passport-strategy');

function CustomStrategy(...) {
  Strategy.call(this);
}

util.inherits(CustomStrategy, Strategy);

Implement Authentication

Implement autheticate(), performing the necessary operations required by the authentication scheme or protocol being implemented.

CustomStrategy.prototype.authenticate = function(req, options) {
  // TODO: authenticate request
}

Tests

$ npm install
$ npm test
