​
1. Install and Setup SDK

In the root of your project run the install command with your package manager of choice.

Import and initialize the SDK in your codebase with the API key and Gateway from the previous step

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

Use the upload method to upload a File object.

You should get a response object like the one below

{
    id: "349f1bb2-5d59-4cab-9966-e94c028a05b7",
    name: "file.txt",
    cid: "bafybeihgxdzljxb26q6nf3r3eifqeedsvt2eubqtskghpme66cgjyw4fra",
    size: 4682779,
    number_of_files: 1,
    mime_type: "text/plain",
    user_id: "7a484d2c-4219-4f80-9d9d-86b42461e71a",
    group_id: null
}

The unique thing about Pinata’s File API is the CID or Content Identifier. Its a unique hash based on the content ofthe file.

​
3. Retrieve a File through a Gateway

Use the cid of a file to fetch it through a Gateway, or create a signed URL.

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.get("bafkreibm6jg3ux5qumhcn2b3flc3tyu6dmlb4xa7u5bf44yegnrjhc4yeq");
    console.log(data)

    const url = await pinata.gateways.createSignedURL({
       	cid: "bafkreib4pqtikzdjlj4zigobmd63lig7u6oxlug24snlr6atjlmlza45dq",
    	expires: 1800,
    })
    console.log(url)
  } catch (error) {
    console.log(error);
  }
}

main();
