To pre-fill form inputs through ejs, first of all you need to set the cookies via res.cookie() .To autofill these values in a form field .You need to get the cookies from the request and assign it to your render method.

For this you can use cookie-parser middleware like this and get the cookie values in req.cookies/req.signedCookies.

var express = require('express')
var cookieParser = require('cookie-parser')

var app = express()
app.use(cookieParser())

app.get('/', function (req, res) {
  // Cookies that have not been signed
  console.log('Cookies: ', req.cookies)

  // Cookies that have been signed
  console.log('Signed Cookies: ', req.signedCookies)
})

app.listen(8080)

From the route you can call your ejs render method with all the properties to autofill

something like

res.render('user_profile',{name:req.cookies.name, age:req.cookies.age})

You can then place the values in your ejs form fields as like

<input type="text" id="name" value="%name%"/>
<input type="text" id="age" value="%age%"/>

When you response , try this:

res.render("your_page", {email: req.body.email, password: req.body.password});

And set email and password to value of input (with ejs).

Cookies can be retrieved from req.headers.cookie and the same can be passed to EJS template or anywhere else based on requirement.

For Example :

Print cookie in console:

router.get("/example"), (req, res) => { console.log(req.headers.cookie); }
