PRE-POST-VALIDATION

This is a very simple to use javascript library for professionally validating the user input before POST request for Login and Register.

fields include name, email, password, confirm_password

The validation checks for the following

Name must be between 2 and 30 characters, Name required, Email required and is not invalid, Password required and must be at least 6 characters, Confirm Password field is required, Passwords must match.

practical usage

Run npm install pre-post-validation

and then

const validateRegisterInput = require('pre-post-validation');
// or you can import like this
import { validateRegisterInput } from 'pre-post-validation';


const validateLoginInput = require('pre-post-validation');
// or you can import like this
import { validateRegisterInput } from 'pre-post-validation';

The functions are called with (data) property which includes the user data. and return errors and isValid.

const router = express.Router();

router.post('/register', (req, res) => {

const { errors, isValid } = validateRegisterInput(req.body);

     if (!isValid) {

        return res.status(400).json(errors);
    }
    else {
        // add your logic after the validation passed.
    }
}

router.post('/Login', (req, res) => {

const { errors, isValid } = validateLoginInput(data);

    if (!isValid) {

        return res.status(400).json(errors);
    }
    else {
        // add your logic after the validation passed.
    }
}

Every time you call this function you have to do some destructuring by taking out const { errors, isValid } and check isValid property for validation.
