I'm a beginner and I've been using github-learning-lab.
It states to use app.use(bodyParse.json())
to perform a POST request, but VSCode states that 'body-parse' is deprecated.
I searched online and most people say to use app.use(express.json())
for the current version of Express
My express version: 4.17.1
My node version: 14.17.0
const express = require('express');
const app = express();
app.use(express.json());
app.use(express.urlencoded({ extended: false }))
const mockUserData = [
{name: 'Mark'},
{name: 'Jill'}
]
app.get('/users', function(req, res){
res.json({
success: true,
message: 'successfully got users. Nice!',
users: mockUserData
})
})
// colons are used as variables that can be viewed in the params
app.get('/users/:id', function(req,res){
console.log(req.params.id);
res.json({
success: true,
message: 'got one user',
user: req.params.id
})
})
app.post('/login', function(req,res){
// Typically passwords are encrypted using something like bcrypt before sending to database
const username = req.body.username;
const password = req.body.password;
// This should come from the database
const mockUsername = 'billyTheKid';
const mockPassword = 'superSecret';
if (username === mockUsername && password === mockPassword) {
// In practice, use JSON web token sign method here to make an encrypted token
res.json({
success: true,
message: 'password and username match!',
token: 'encrypted token goes here'
})
} else {
res.json({
success: false,
message: 'password and username do not match'
})
}
})
app.listen(8000, function(){
console.log('server is running')
})

CodePudding user response:
I reinstalled express. I may have made a mistake when installing it initially. I should've tried this from the start. Thanks for the help.
CodePudding user response:
First you could use Bodyparser or you should reinstall it, but I recommend using Bodyparser
