The IPFS SDK is an all-in-one tool for everything you might need, from uploading content, using Gateways, even user or group management!

​
1. Installation and Setup

Install with your package manager of choice

npm i pinata

Import and initialize the SDK in your codebase with the following variables

import { PinataSDK } from "pinata";

const pinata = new PinataSDK({
  pinataJwt: "PINATA_JWT",
  pinataGateway: "example-gateway.mypinata.cloud",
});
The PINATA_JWT is a secret key, be sure to initialize the SDK in a secure environment and practice basic variable security practices. If you need to upload from a client environment, consider using signed JWTs

​
2. Upload a File

import { PinataSDK } from "pinata";

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

async function main() {
  try {
    const file = new File(["hello"], "Testing.txt", { type: "text/plain" });
    const upload = await pinata.upload.public.file(file);
    console.log(upload);
  } catch (error) {
    console.log(error);
  }
}

await main();

This will return an object like the following

{
    id: "41bc6820-43d3-46f8-a9e0-e53e8adea2e8",
    name: "hello.txt",
    cid: "bafkreid7qoywk77r7rj3slobqfekdvs57qwuwh5d2z3sqsw52iabe3mqne",
    size: 12,
    number_of_files: 1,
    mime_type: "text/plain;charset=utf-8",
    group_id: null,
}

​
3. Retrieve a File

Use the cid of a file to fetch it through a Gateway or create a URL to access it

import { PinataSDK } from "pinata";

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

async function main() {
  try {
    const data = await pinata.gateways.public.get("bafkreibm6jg3ux5qumhcn2b3flc3tyu6dmlb4xa7u5bf44yegnrjhc4yeq");
    console.log(data)

    const url = await pinata.gateways.public.convert("bafkreib4pqtikzdjlj4zigobmd63lig7u6oxlug24snlr6atjlmlza45dq")
    console.log(url)

  } catch (error) {
    console.log(error);
  }
}

main();
