To upload a string to IPFS using Helia, you must first install the helia and @helia/strings packages, then initialize a node and use the strings.add() method to store the content.

import { createHelia } from 'helia'
import { strings } from '@helia/strings'

const helia = await createHelia()
const s = strings(helia)

// Add the string and get its CID
const myImmutableAddress = await s.add('hello world')
console.log(myImmutableAddress) // e.g., CID(bafy...)

// Verify retrieval
const retrieved = await s.get(myImmutableAddress)
console.log(retrieved) // "hello world"

Key Considerations for Public Accessibility:

  • Persistence: Helia stores data locally by default; to make content accessible via public gateways (like ipfs.io), you must pin the content using a pinning service (e.g., Pinata, Web3.storage) or keep your node running with a public IP.

  • Network Propagation: If you cannot access the content via a gateway immediately, it may be because your node is not discoverable by the global network or is behind a firewall that blocks incoming Bitswap connections.

  • Alternatives: For web applications requiring immediate public availability without self-hosting, consider using ThirdWeb or dedicated IPFS Pinning Services that handle the network propagation and storage persistence.

How to retrieve content uploaded via Helia using the IPFS gateway? - Helia - IPFS Forums
15 June 2023 - Tried using Helia today: import { createHelia } from 'helia' import { strings } from '@helia/strings' const helia = await createHelia() const s = strings(helia) console.log(await s.add('quick test djkfjdkfjd')); It returned this hash: bafkreidoqdzmahiqe75jsfuu3cm3wdrmeipvjtz4b7l5xpuaidnlt65f3a And yet, the IPFS gateway returns an error when looking it up: https://ipfs.io/ipfs/bafkreidoqdzmahiqe75jsfuu3cm3wdrmeipvjtz4b7l5xpuaidnlt65f3a Why is that?

What's the best way to handle uploads to IPFS from a web app?
Helia does not actually commit to IPFS so it’s not an option. It (by default) stores in memory: The datastore can be configured with ones from js-stores, however none of them actually store on the IPFS network: GitHub - ipfs/js-stores: TypeScript interfaces used by IPFS internals.

How to upload data with javascript code
Inside of the IPFS cloud you don't really upload your data to anywhere, but instead you just offer it from your own node. Other people can find it from you and request it from you if they want. A gateway is a way for people not inside of the cloud to request data from the cloud. I may be wrong as I've never tried to use it, but I thought Helia makes you part of the cloud. If that's right, then there's no uploading or gateways to specify. Content that you provide via Helia is just there so long as you keep Helia running. I'm guessing that's your problem, you give Helia the content to provide then you close it, at which point it's no longer provided. More on reddit.com

How can I integrate Helia to incorporate IPFS (InterPlanetary File System) as a cloud storage solution for a website?

Let's begin by understanding the basics of IPFS IPFS is not cloud storage There is no uploading your files to IPFS. So what is it then ? ( Video ) When you "upload" file to IPFS you are storing the file on your system (or a third party system if you are using any services), you just compute the hash of the file. Let's say Qm...123, and you simply anounce to everyone who is using IPFS, saying "Hey, I have Qm...123" Now suppose I want a file whose hash is Qm...123, then ask the network "Anyone has Qm...123 ?", they you respond to me and we transfer the file (using Bitswap protocol). Think of it as BitTorrent , but even better. Now to your question, what do you mean by Cloud Storage solution ? There are two possible meaning of this You want to store users data on IPFS You want to store your files on IPFS (images, videos) and then provide it to users. For storing user generated content on IPFS: Since there is not cloud storage. A user can make this file available to the network. But if the user's device is offline then the content is not accessible by anyone. Here comes "Pinning", pinning refers to persistently keeping a file on a node. So the steps would be, the user make the file available on IPFS, then you (or a pinning service) pin the file. Once a file is pinned the user can go offline, while the pinning service will take care of the availablity of your file. You have to pin the file somewhere, either on your own server or on a pinning service like Pinata , Web3.storage or even better a decentralized pinning service like Crust.Network . 2. You want to store your files on IPFS (images, videos, etc) and then provide it to users. In such case, still you are required to pin the file somewhere (it is possible that you host your files on your own setup). Or make use of pinning services. Then you can leverage IPFS based CDN like Saturn Network , to get your content delieverd faster. Helia in browser is not very reliable, you can read about it more here . Hope this helps, if you have any further questions feel free to ask them. Please also take a look at official documentation and IPFS Community Forums for more details.

r/ipfs on Reddit: How to upload data with javascript code
7 October 2023 -

Hi, I'm sorry if this is a trivial issue, I am very new to IPFS and I'm using the new library called Helia with my Javascript app (specifically with react).

I have tried many ways of making a helia node like the ones mentioned here and the ones here. I have been trying for weeks to upload my data to the IPFS and be able to access it from a public gateway like ipfs.io/ipfs. I do get a CID returned to me using these methods but it doesn't show when I go to ipfs.io/ipfs/${cid}.

Please help me out and let me know where I must specify the public gateway to upload the data so I can see it when I use the gateway and CID. Thanks a lot 🙏

EDIT

Thanks for everyone who tried to help. I found this amazing tool and it seems to be working for me. You can check out this video for a short demo on using this. This library is called ThirdWeb and it does EXACTLY what I needed. Although it requires you to have a Web3 wallet and an API_key/client_ID (for your environment variables) which you can get from here.

Currently trying to figure out how it works and recreate some of the functionality myself. It's strange because this @thirdweb-dev/storage mentions neither IPFS-JS nor Helia in its dependencies so I have no idea how it is even accessing the IPFS network... yet.

For those who want to check out my code, here is the repo: https://github.com/Electromorphous/DeNotes

How to connect to local nodes and modify metadata in the new Helia library?
Since the ipfs-http-client has been deprecated and replaced with Helia, I find myself unable to upload pictures to the ipfs-desktop, detect local nodes, and modify the picture's metadata as I used to. I couldn't find any documentation on how to connect to local nodes and modify metadata with Helia. Here's how I used to operate: async function run() { const { create } = await import('ipfs-http-client'); const ipfs = await create(); const metadata = { path: '/', content: JSON.stringify({ name: "My First NFT", attributes: [ { "trait_type": "Peace", "value": "10" }, { "trait_type": "Love", "value": "100" }, { "trait_type": "Web3", "value": "1000" } ], image: "https://ipfs.io/ipfs/QmQ2wnwaFJ1w42UTywTWpM8RgiqrWwKFR6AMrpyiHPgi3p", description: "So much PLW3!"

You upload data/files to your node or pinning services. But the whole point of IPFS is that every node is a like a server for data it has. This means that when you add data to Helia in node.js (and you have a public IP so you are reachable over the internet), and you provide a CID you become a provider for it.
