Upload a single file to Pinata
Usage
import { PinataSDK } from "pinata";
const pinata = new PinataSDK({
pinataJwt: process.env.PINATA_JWT!,

});

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.file(file);
Returns
type UploadResponse = {
id: string;
name: string;
cid: string;
size: number;
number_of_files: number;
mime_type: string;
user_id: string;
};
