express-validator does not work without (deprecated ?) body-parser












0















I have seen a number of posts which seem to say body-parser is deprecated at least for using with express-validator. I also can see no mention of body-parser on the express-validation documentation Getting Started page. However, when I try and follow that Getting Started tutorial I find I can not get it to work without body-parser. I could not follow their tutorial precisely because I did not understand some of it but I do not think the simplifications I have made would be relevant to this issue.



My question is: is it OK to use body-parser in the way I am doing it?



Below is what I did (I have node version 10.10.0):



mkdir express-validator
cd express-validator
npm install --save express
npm install --save express-validator


app.js file:



const express = require('express')
const app = express()

app.use(express.json())

const { check, validationResult } = require('express-validator/check')

const bodyParser = require('body-parser')

app.use(bodyParser.urlencoded({ extended: false }))

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()) {
res.send(errors.array())
return
}
res.send('ok')
})

app.listen(5000, () => console.log(`listening on port $5000`))


I start the server using node app.js



Then I use curl:



curl -d username=fred@gmail.com -d password=12345 localhost:5000/user


That works ie I get OK sent back. If I remove the @ symbol from the email address I get this:



[{"location":"body","param":"username","value":"fredgmail.com","msg":"Invalid value"}]


If I comment out the line: app.use(bodyParer.url etc etc I get the error.array() sent back with both the curl commands above.



Is it OK to use body-parser as I have done? If not what should I do to get this to work?
