Can a string or javascript object be uploaded without being saved in a file? - IPFS

I've been exploring the capabilities of js-ipfs API and I'm curious to know if js-ipfs is limited to only uploading files/folders. Is there a way to upload other types of data, such as a JavaScript object like:

{
    heading:"SomeHeading",
    content:"somecontent"
}

or a string like

"{heading:\"SomeHeading\", content:\"somecontent\"}"

So far, my attempts have involved:

const ipfs = window.IpfsApi('localhost', 5001, {protocol: 'https'});
const buffer = ipfs.Buffer;

async function uploadToIpfs() {
    let someObject = {
        heading:"SomeHeading",
        content:"someContent"
    };

    let objectString = JSON.stringify(someObject);

    let bufferedString = await buffer.from(objectString);

    await ipfs.add(bufferedString, (err, resp) => {
        console.log(err);
        console.log(resp);
    });
}

but I encounter

Any assistance in resolving this issue or a straightforward answer on whether it's feasible to directly upload a JS object or string would be highly appreciated!

Answer №1

After testing the code you provided, it appears that a simple modification is necessary to switch the protocol from https to http if you are working on localhost.

{protocol: 'http'}

Answer №2

If your question is about uploading random object content, then you may be interested in utilizing an abstract-blob-storage. One way to achieve this is by using the ipfs-blob-store library.

Be sure to refer to the documentation for detailed information, but here is a basic overview:

var ipfsBlobStore = require('ipfs-blob-store')

var options = {
  port: 5001,   // default value
  host: '127.0.0.1', // default value
  baseDir: '/', // default value
  flush: true  // default value
}    
var store = ipfsBlobStore(options)

var ws = store.createWriteStream({
  key: 'some/path/file.txt'
})

ws.write("{heading:\"SomeHeading\", content:\"somecontent\"}")
ws.end(function() {
  var rs = store.createReadStream({
    key: 'some/path/file.txt'
  })

  rs.pipe(process.stdout)
})
