Authentication in ASP.​NET Core for your Web API and Angular2+ using JWT 🔑

Authentication in a single page application is a bit more special, if you just know the traditional ASP.NET way.

To imagine that the app is a completely independent app like a mobile app helps.

Token based authentication is the best solution for this kind of apps.

Yagni : You Arent Gonna Need It 👾

Never Add Functionality Early 💡

"Always implement things when you actually need them, never when you just foresee that you need them."

Even if you're totally, totally, totally sure that you'll need a feature later on, don't implement it now. ⏳

Usually, what you actually need is quite different from what you foresaw needing earlier. 🙅🏻‍♂️

This doesn't mean you should avoid building flexibility into your code. ✅

It means you shouldn't overengineer something based on what you think you might need later on. ❌

🔹🔸🔹🔸🔹🔸

There are two main reasons to practise YagNi :

1️⃣ You save time, because you avoid writing code that you turn out not to need.

2️⃣ Your code is better, because you avoid polluting it with 'guesses' that turn out to be more or less wrong but stick around anyway.

This also follows the KISS theorem:

Keep it simple, stupid!

Difference between \n and \r 👀

In Unix and all Unix-like systems, \n is the code for end-of-line, \r means nothing special. 🤷🏻‍♂️

As a consequence, in C and most languages that somehow copy it (even remotely), \n is the standard escape sequence for end of line (translated to/from OS-specific sequences as needed)

in old Mac systems (pre-OS X), \r was the code for end-of-line instead. 🖥

As a (surprising) consequence (harking back to OSs much older than Windows), \r\n is the standard line-termination for text formats on the Internet. 🌏

For electromechanical teletype-like "terminals", \r commands the carriage to go back leftwards until it hits the leftmost stop (a slow operation), \n commands the roller to roll up one line (a much faster operation) — that's the reason you always have \r before \n, so that the roller can move while the carriage is still going leftwards!.

For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller) 😉

DRY - Dont Repeat Yourself 🙅🏻‍♂️

Duplication can lead to maintenance nightmares, poor factoring, and logical contradictions. ❌

The DRY Principle states :

"Every piece of knowledge must have a single, unambiguous, authoritative representation within a system."

🔹🔸🔹🔸

Duplication, and the strong possibility of eventual contradiction, can arise anywhere in :

• Architecture
• Requirements
• Code
• Documentation

The effects can range from mis-implemented code and developer confusion to complete system failure.

🔺🔹🔺🔹

Advantages of DRY 💎 :

• Maintainability
• Readability
• Reuse
• Testing

Do You Know Where Your TempData is ❓

TempData is a bucket where you can dump data that is only needed for the following request. 📦

That is, anything you put into TempData is discarded after the next request completes. ❎

This is useful for one-time messages, such as form validation errors❗️

If you need something more persistent, Session is likely what you’re looking for. 📥

By default, TempData is stored in the session.

🔹🔸🔹🔸

In this article you see how TempData works and how you can use another provider instead of Session to store the data. 🌀
