const express = require('express')
const app = express()
app.get('/', function (req, res) {
const { body } = req
validateObjectWithKeys(headers, null, "username", "age")
.then(req => validateString(req["username"], []))
.then(tuple => validateNumber(req["password"], tuple))
.then(([username, password])=>{
// Handle valid logic.
})
.catch(e=>{
//Handle the rejection logic
res.send("The parameter username or age weren't sent in the request or they got invalid data type."))
}
})
app.listen(3000)Use chained promise calls to help you efficiently validate variables, for example, handling express request object.
