Hello everyone,

The ipfs-http-client JavaScript library can be used to list the objects pinned to your Infura IPFS account. In order to do so follow the next steps:
Install the library from the official ipfs-http-client .
Declare the IPFS client and use the below piece of code to list the pinned objects to your local storage.
Don’t forget to use your Project ID and Project Secret.

const {ipfsClient, create, CID} = require('ipfs-http-client')
const projectId = '27h....xxxx....Rsj';
const projectSecret = '205....xxxx....15b';

async function listCids(){
    const auth =
      'Basic ' + Buffer.from(projectId + ':' + projectSecret).toString('base64')
    const client = await create({
        host: 'ipfs.infura.io',
        port: 5001,
        protocol: 'https',
        headers: {
          authorization: auth
        }
      })
      for await (const { cid, type } of client.pin.ls()) {
             console.log({ cid, type })
      }
     
}

listCids()

The output of the code run will display the pinned CIDs, including their type: recursive, direct or indirect.

The pin.ls api supports the type object, which can be used to filter the pins by their type: “recursive”, “direct” or “indirect”.
So, if you’d like to get just the recursive pins, use the type object with the recursive key as per the below example:

    for await (const { cid, type } of client.pin.ls({type: 'recursive'})) {
             console.log({ cid, type })
      }

Another useful feature supported by the pin.ls api is the paths object, which comes in handy when searching for a CID in the pinset, especially if you have a multitude of CIDs pinned to your local storage and you aren’t sure if a particular one is pinned or not. See the below example for this:

      for await (const { cid, type } of client.pin.ls({paths: [ CID.parse('QmehKEbtk4wHihtfB48VF2WC6Sis3u1Ad2tbUsSUg5mmWH') ]})) {
             console.log({ cid, type })
      }

The above code will return the CID together with its type, if the object is pinned to your local pinset.

{
  cid: CID(QmehKEbtk4wHihtfB48VF2WC6Sis3u1Ad2tbUsSUg5mmWH),
  type: 'recursive'
}

Or it will return an error similar to the below one if the object is not pinned to your account:

HTTPError: path 'QmehKEbtk4wHihtfBs8VF2WC6Sis3u1Ad2tbUsSUg5mmWH' is not pinned

:bulb: You can use node to write the results of your pin.ls directly to a file. Let’s assume that the name of the file containing your code is pinls.js and that you want to create a log file containing all your recursive pins. Use the {type: ‘recursive’} filter, as explained earlier, change directory to the folder where pinls.js is located and then run the below command from your terminal window.

node pinls.js > recursivepins.log 2>&1

The results will be written in the recursivepins.log file, while if you hit an error this file will contain the error details.
