How to use express-validator in nodeJs?










0















I am trying to use express-validator in my nodeJs example,

I trying a basic validation of whether username and password are valid,

username has to be an email address and

the password needs to be minimum 5 characters long.

I am using the example from the official doc



Following is the sample code I'm trying to run -



const express = require('express');
const app = express();
const check, validationResult = require('express-validator/check');

app.use(express.json());

app.all('/*', function (req, res, next)
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', "GET, POST, PUT, PATCH, DELETE, OPTIONS");
res.header("Access-Control-Allow-Headers", 'Content-Type, Accept, X-Access-Token');

if (req.method == 'OPTIONS')
res.status(200).end();
else
next();

);

app.post('/user', [
// username must be an email
check('username').isEmail(),

// password must be at least 5 chars long
check('password').isLength( min: 5 )
], (req, res) =>

// Finds the validation errors in this request and wraps them in an object with handy functions
const errors = validationResult(req);

if (!errors.isEmpty())
return res.status(422).json( errors: errors.array() );


User.create(
username: req.body.username,
password: req.body.password
).then(user => res.json(user));

);

var server = app.listen(8085, function ()
var host = server.address().address
var port = server.address().port
console.log("Example app listening at http://%s:%s", host, port)
);


Following is the error I am getting when I call the API using POSTMAN -
enter image description here



For some reason, the validation fails despite passing a valid email as username and 5 characters long password,

What is the mistake, Can someone help?

    Look like an issue in your Body params in the request. Use JSON instead of Text.
