Passport VS dotenv

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Passport is outdated and the project has been more or less on a stand-still for years now.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.

We will put our Emailjs environment variables in a dotenv (.env) file. To read more about the purpose of this file click here.

Add .env to your .gitignore file to prevent it from being committed. Here's an example file with it already added. You may also use dotenv for advanced configuration and it will automatically load environment variables from a .env file into process.env.

dotenv: Designed to load environment variables from a .env file into the process.env environment

Like Doppler, Infisical uses environment variable injection. Similar to the Dotenv package for Node, when used in Node, it injects them at run time into the process object of the running app so they're not readable by any other processes or users. They can still be revealed by a crash dump or logging, so that is a caveat to consider in your code and build scripts.

We'll be working with databases' ids and different info that should be secured so I would advise you to create a .env file to store said info. We'll do this by installing dotenv into our project and use it accordingly:

dotenv - For reading our API keys from the environment

As an avid dotenv user I wanted to thank their maintainers for keeping the project alive for 10 years (wow). A perfect exemplary of dedication to Open Source.

Sensitive data like database URLs, API keys, and passwords should never be hardcoded in your application code. Instead, use environment variables accessed at runtime to keep this information secret. Popular dotenv libraries like dotenv make this easy for Node.js apps.
