To-doz-Backend

NOTE: This is all experimental, I am just having fun so if you actually deploy this be careful.

Where to deploy this..?

You can deploy this on Render (perfect option), Microsoft Azure App Services (Only 1 hour a day), Vercel (crashes), Netlify (Need verification), Heroku (Requires card verification)

Different servers

There is two ways to deploy this but the only way that works now is the "Setup - Normal" way.

Credits

The code uses a significant portion of the "API Design" course code from Frontendmasters https://github.com/Hendrixer/api-design-v4-course

I modified it to add some changes.

Setup - Normal

Add the env variables: Please make the SUPER_SECRET_TOKEN very long and random

ORIGIN_SITE="https://zarmdev.github.io/To-doz-React/"
SUPER_SECRET_TOKEN="putanyvalueyouwant"

Don't change user.ts

Deploy the server normally.

About the Experimental way (JWT tokens)

This is meant for deploying a "production" database where there is multiple users, but obviously there are many flaws in it. Problems I found:

• I don't know how to do security very well
• Might be slow
• Doesn't have error handling - so will crash in many cases
• Passwords can be brute forced
• I may have broken lots of features while writing new code?

Setup - JWT tokens (Experimental, still working on it)

Add the env variables: (I kinda have no idea what I'm doing)

ORIGIN_SITE="https://zarmdev.github.io/To-doz-React/"
JWT_TOKEN="putanylongvalueyouwant"

Uncomment // import db from '../server' in user.ts and comment the line below it

When you deploy your server, make sure it runs npm run startExperimental If you can't get it to do that, you can also switch up the commands to have npm run start do the startExperimental command

Other Notes

Don't try to change your server from secure server to JWT tokens, it will probably break it.

Security

So is it actually secure..?

This is what it checks:

• First, it makes sure you provided the SUPER_SECRET_KEY in the bearer authorization header
• Second, it makes sure you have a valid password with your username
• Third, it has a rate-limiter that has the following rate limits:

100 requests in 2 hours app.post('/api/getdata', limiter, getUserData)

500 requests in 2 hours app.post('/api/updatedata', lightLimit, updateUserData)

500 requests in 2 hours app.post('/api/updatesection', lightLimit, updateSection)

• Fourth, it blocks requests that don't originate from:

	'http://localhost:3000',
	'http://localhost:3000/To-doz-React',
	'https://zarmdev.github.io/To-doz-React/',

So, when creating your SUPER_SECRET_KEY, make sure it's very strong.

If you use https://passwordsgenerator.net/, then it will give you a 22 character password that takes centuries to crack.
