React: Use Axios To Post State To Mongodb

I am trying to post the states as data to MongoDB through Express and Node with Axios. class App extends React.Component { constructor(props){ super(props) this.state={

Solution 1:

To access the req.body we need to use body-parser middleware which Parse incoming request bodies in a middleware before your handlers.

Installation

$ npm install body-parser

>

var app = require('express')();
var bodyParser = require('body-parser');

app.use(bodyParser.json()); // for parsing application/json

Solution 2:

Please use app.post in the server, currently you are creating a get endpoint you should first make a post endpoint to make a post request. Please also check https://expressjs.com/en/guide/routing.html
