I am very new to node js. I am just testing some stuff about client-server communication.

I have these codes:

server:

app.post('/zsa', (req, res) => {
    res.send("zsamo");
});

client:

fetch("http://localhost:3000/zsa", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify(data),
})
  .then((data) => {
    console.log(data);
  });

With this code i get a response object:

I want to log to the console what was in the response data: "zsamo"

fetch returns a Response. If you want JSON from the body of your response then you can do this:
```
fetch(url)
  .then(response => response.json())
  .then(data => console.log(data));
```
