Express validator usage

Express validator middleware is used to validate user input in a request

Routine is also fully compatible with this middleware example

const Routine = require('routinejs')
const { body, validationResult } = require('express-validator')
const app = new Routine({
    enableBodyParsing: true,
    catchErrors: true,
})

app.post(
    '/user',
    body('username').isEmail(),
    body('password').isLength({ min: 5 }),
    (req, res) => {
        const errors = validationResult(req)
        if (!errors.isEmpty()) {
            return res.status(400).json({ errors: errors.array() })
        }
    }
)

app.listen() //:8080
