You put the wrong lib name.

Is not const bodyparser = require('body-parse').

Forgot an "r".

The right thing is const bodyparser = require('body-parser')

Using the express version >= 4.16.0 is no longer necessary to install the body-parser to use the express. Follow the pr link with the merge: https://github.com/expressjs/express/issues/2211 That was merged on 25/09/2017.

The correct way is to use express itself to enable body parser features, follow an example:

const express = require('express');

const app = express();

app.use(express.json()); //esta linha ativa o body-parser.

app.use(require('./server/index'));

module.exports = app;

If you do not want to use this approach, you should install the lib body-parser.

To do this just use the command:

$ npm install body-parser

Here is a full example of how to use this strategy:

const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');

const app = express();
cors({ credentials: true, origin: true });
app.use(cors());
app.use(bodyParser.json({ type: 'application/json' }));
app.use(bodyParser.urlencoded({
    extended: true
}));

app.use('/', require('./server/index'));
//declaracao de rotas
app.get('*', function(req, res) {
    res.status(404).json({msg: "not found"})
});

module.exports = app;
