node-fetch

How do I attach a file in Node or Node Fetch POST request? I am trying to invoke an API which will import a CSV or XLS file. Is this possible using Node or Node Fetch? README.md says: Use native stream for body, on both request and response. And sources indicate it supports several types , like Stream , Buffer , Blob ... and also will try to coerce as String for other types. Below snippet shows 3 examples, all work, with v1.7.1 or 2.0.0-alpha5 (see also other example further down with FormData ): let fetch = require('node-fetch'); let fs = require('fs'); const stats = fs.statSync("foo.txt");
