How do I write a user login system with JavaScript?

Using jwt

Send username and password to server. Use ajax or just plain post request.

sudo code

if user == "user1" && password == "password1":
    login("user1")
else if user == "user2" && password == "password2":
    login("user2")
...
else:
    return false

that doesn't look very secure

php

Just change the variable names so it's harder for the hackers to figure out what the code does, client side.

client side crypto libs exist like aes and bcrypt

why would you write it with JS?

Why would u even write this in javascript clientside, do it server side

That does not sound like a safe solution. Would be better to check it somewhere else.

Do I even need a SQL DB if all I need to store is a dozen users ?

I want thinking of just having a text file server side with some synthax like
username:pwd:arg1:arg2:etc..

Of course not.
You should be using MONDODB like the rest smart individuals who write js.

Use noSQL

So, theoretically, if someone was new to these programmings, how would someone go about writing it server side?

>How do I write a user login system with JavaScript?
Except it runs on the server side, you don't.

It will be insecure as fuck

Hard coding every user in.
Might as well off yourself.

It's completely safe, just trust me.
