Passport VS fastify

Next, use something like https://www.npmjs.com/package/passport, this is authentication middleware, and it works similarly for different authentication providers. Carefully read the documentation. OAuth is complicated, but that's because it solves a complicated problem

Passport is outdated and the project has been more or less on a stand-still for years now. As of currently, there are more than 320 open issues and very few have been resolved within the last months. I'd highly advice you not to use Passport for your applications in 2023. You've received some great alternatives by others in the comments here.

lib: The lib folder, short for "library", is mostly used to store the actual source code of the package, but it can also be used to store third-party code, utilities and helpers. Example from passport.

Research - there's github and stackoverflow documentation saying this is part of passport.js 0.6.0 that can be resolved by turning logout into a callback function (I was not the first person to encounter this error).

passport for authentication

I went down the rabbithole of using next-auth (now authjs) for a recent project. Having used Passport.js [1] for Oauth2 the last time I was doing node.js ~3 years ago, I found this library to have many footguns as comments/answers on SO and Github.

Seems like many people are trying to shoehorn their codebase [2] (!!) to make it work with the way the library manages sign-in flow, redirects, cookies, logout, etc. [3]

These were solved problems in the MEAN stack era with middlewares, but now that Next.js/react is the trend, people are doing everything they can to make it work - from relaxing security configs, to stashing things in the JWT just so some callback can get an additional piece of data.

Checkout using NestJS that uses Passport or just checkout Passport

For example, Fastify removed the instanceof operatorfrom its codebase because it was causing problems for those developers that rely on jest as a testing framework.

Both are frameworks but NextJs is for Forntend (web app in browser that use ReactJs under the hood) and NestJs is for Backend (server app running on a server witch use Express or Fastify). The only thing similar between them is the typed language in which they were written.

Restify & Fastify Hapi

Let's create a sample Node API project we can work with throughout to build a new docker image. We will leverage Fastify to create an API that we configure via the fastify-cli.

Fastify

In setting out to build this service, we wanted to use gRPC for its APIs. We’ve been reaching for REST when building APIs so far, primarily out of necessity, i.e., our public APIs needed auto-generated client SDKs and docs for developers working with them. We built those APIs with Fastify and Typebox but felt burned by a code-first approach to generating an OpenAPI spec. I’ll spare you the details and save that experience/learning for another article. Suffice it to say we love gRPC’s schema-first approach. This blog post summarizes our feelings well

Fastify – Fast and Low overhead web framework

Custom Functions are powered by Fastify (a light-weight Node.js framework that claims to be faster than Express.js), so they’re extremely flexible.
