​
Usage

import { PinataSDK } from "pinata";

const pinata = new PinataSDK({
  pinataJwt: process.env.PINATA_JWT!,
  pinataGateway: "example-gateway.mypinata.cloud",
});

​
Local Files

If you need to upload files from a local file source you can use fs to feed a file into a blob, then turn that blob into a File. 
const { PinataSDK } = require("pinata")
const fs = require("fs")
const { Blob } = require("buffer")

const pinata = new PinataSDK({
  pinataJwt: process.env.PINATA_JWT!,
  pinataGateway: "example-gateway.mypinata.cloud"
})

const blob = new Blob([fs.readFileSync("./hello-world.txt")]);
const file = new File([blob], "hello-world.txt", { type: "text/plain"})
const upload = await pinata.upload.public.file(file);
