How to determine the size of a stream?

Question

JavaScript

const result = await axios({
            url,
            method,
            responseType: 'stream'
        });

There is an axios request that downloads an excel file from the server.
You need to determine its size, so that if it is large - archive it.
Tell me how can I get the size of this file (result in the code) in node.js?

Answer 1

Get the header via axios Content-Length, the file size will be indicated there
