ipfs-storage

IPFS STORAGE API PROVIDERS

This library provides a unified interface for uploading files to and deleting files from various IPFS storage providers.

Supported Providers:

• Filebase [filebase.com]
• Storacha [storacha.network] (formerly web3.storage)
• Pinata [pinata.cloud]
• Lighthouse [lighthouse.storage]
• Fleek [fleek.xyz] (Temporarily Disabled)

Prerequisites

• Node.js: Version 18 or higher.
• Credentials: You will need API credentials for each service you intend to use. Store these securely, for example, using environment variables (see examples).
• Storacha Setup: Storacha requires a one-time setup using their CLI (w3) to log in your agent (w3 login <email>) and create/select a space (w3 space create, w3 space use). This library assumes the agent is already configured in the environment where the code runs.

Installation

npm install ipfs-storage
# or
yarn add ipfs-storage

Breaking Changes (v1.x -> v2.x)

• Pinata: uploadFile.pinata now returns an object { url: string, providerId: string }. The providerId is required for deleteFile.pinata.
• Fleek: Authentication changed (requires PAT/ProjectID), but the provider is temporarily disabled due to module resolution issues with @fleek-platform/sdk in ESM projects.
• Storacha (web3.storage): Authentication requires a pre-configured agent (via w3 login) instead of an API token.
• Dependencies: Underlying SDKs for all providers have been updated.

Examples

First, set up your environment variables (e.g., in a .env file and load with dotenv):

# Filebase
FILEBASE_KEY=YOUR_FILEBASE_ACCESS_KEY
FILEBASE_SECRET=YOUR_FILEBASE_SECRET_KEY
FILEBASE_BUCKET=your-filebase-bucket-name

# Pinata
PINATA_JWT=YOUR_PINATA_JWT

# Storacha (No key needed here, login via w3 cli)

Then, use the library in your code:

const fs = require("fs");
const { join } = require("path");
const { uploadFile, deleteFile } = require("ipfs-storage");
const { create } = require('@web3-storage/w3up-client'); // Needed for pre-configured client example
require("dotenv").config(); // Load .env variables

// Helper function to extract CID v1 from common IPFS gateway URLs
const extractCidFromUrl = (url) => {
  try {
    const urlObject = new URL(url);
    const hostnameParts = urlObject.hostname.split(".");
    // Assuming format like https://{cid}.ipfs.{gateway}/
    if (hostnameParts.length > 2 && hostnameParts[1] === "ipfs") {
      return hostnameParts[0];
    }
  } catch (e) { /* ignore */ }
  return null;
};

// Example usage (run within an async function or use .then())
async function runExamples() {
  let fileBuffer;
  try {
    fileBuffer = fs.readFileSync(join(__dirname, "banner.png"));
  } catch (err) {
    console.error("Error reading file:", err);
    return;
  }

  const fileData = { hash: "banner-test", ext: ".png", buffer: fileBuffer };

        bucket: process.env.FILEBASE_BUCKET,
      };
      const url = await uploadFile.filebase(filebaseConnect, fileData);
      console.log("✅ FILEBASE Upload:", url);

      await deleteFile.filebase(filebaseConnect, { hash: fileData.hash, ext: fileData.ext });
