why my fetch post is not working it is not responding?

Question

addwordform.addEventListener('submit', (event)=>{
  event.preventDefault();
    const formdata=new FormData(addwordform);
    const word=formdata.get('addword');
    const description =formdata.get('addiscription');
    const worddata={
        word,description,totalcount
    };
  console.log(worddata);
  fetch(API_URL,{
      method:'POST',
      headers:{
          'content-Type':'application/json'
      },
      body:JSON.stringify(worddata),
  }).then(response=>response.json()).then( data =>{
     console.log(data);
       });
});

this is the client side javascript here API_URL="http://localhost:3005/word" and server side code is

const express= require('express');
const serveStatic = require('serve-static');
const datastore=  require('nedb');
const app= express();
app.listen(3005,()=>{console.log("listening on :http://localhost:3005")});
app.use(serveStatic('public',{'index':['client.html']}));
const database=new datastore('database.db');
database.loadDatabase();
app.post('/word',(req,res)=>{
   const data=req.body;
   database.insert(data);
   res.json();
});

i am using express a node framework and vanilla javascript for client side all i want is to post the data from a form that has an id=addwordform and i am using nedb a light weight database management in node .problem with it is the worddata that i am sending from client side is not getting in the server side "req" so i cant save it in database and ultimatly i cant "res" it back ?

If you're using express version >= 4.16. Body parser comes bundled with express.

It parses incoming requests with JSON payloads and is based on body-parser.

It is not needed to use body-parser. Here is the documentation

You just have to add this code before require your routes.

app.use(express.json()); 

Here is the stackoverflow original post.

Here is the express release
