Difference between express.js and axios.js in Node

Question

We use axios for http requests such as get, post, etc. We use express for the same purpose also. However according to what I read, they are for different purposes. Please explain how.

PS: If you explain it by giving an example, it would be great!

Answer 1

You can think of express.js as a warehouse:

app.get('/item/:name', async function (req, res) {
  res.send(await findItemByName(req.params.name));
});

If you want to get an item, for example a pencil, from this warehouse, you can use axios.js.

axios.get('/item/pencil')

Answer 2

Axios is used to send a web request whereas express is used to listen and serve these web requests.

In simple words, express is used to respond to the web requests sent by axios.

If you know about the fetch() method in javascript, axios is just an alternative to fetch().
