w3up

This repo implements the web3.storage UCAN protocol specifications.

It's the core of the web3.storage server and client implementations.

Usage

Store your files with web3.storage and retrieve them via their unique Content ID. Our tools make it simple to hash your content locally, so you can verify the service only ever stores the exact bytes you asked us to. Pick the method of using web3.storage that works for you!

Website

Visit https://console.web3.storage and upload right from the website.

Under the hood it uses the web3.storage client that we publish to npm to chunk and hash your files to calculate the root IPFS CID in your browser before sending them to https://up.web3.storage.

Once uploaded you can fetch your data from any IPFS gateway via https://w3s.link/ipfs/<root cid>

Command Line

Install @web3-storage/w3cli globally, authorize it to act on your behalf, create a space and upload your files. It calculates the root CID for your files locally before sending them to web3.storage.

shell

# verify your email to sync your existing ucan delegations to this agent.
$ w3 login alice@example.com

# create a Space, a DID namespace for your files... like a bucket.
$ w3 space create Documents

# lets go!
$ w3 up ~/Pictures/ayy-lamo.jpg
⁂ Stored 1 file

Run w3 --help or have a look at https://github.com/web3-storage/w3cli to find out everything it can do.

JS Client

Add the @web3-storage/w3up-client module into your project with npm i @web3-storage/w3up-client and upload a single file with client.uploadFile or many with client.uploadDirectory.

If you've already got a space you can upload like this:

node.js

import { filesFromPaths } from 'files-from-path'
import * as Client from '@web3-storage/w3up-client'

const [,,yourEmail, pathToAdd] = process.argv

// authorize your local agent to act on your behalf
const client = await Client.create()
await client.login(yourEmail)

// lets go!
const files = await filesFromPaths(pathToAdd)
const cid = await client.uploadDirectory(files)

console.log(`IPFS CID: ${cid}`)
console.log(`Gateway URL: https://w3s.link/ipfs/${cid}`)
Copy

See https://web3.storage/docs/w3up-client for a guide to using the js client for the first time.

GitHub Action

The Action add-to-web3 wraps w3cli to let you add files to web3.storage from your GitHub Workflows.

github-workflow.yaml

- run: npm run build # e.g output your static site to `./dist`

- uses: web3-storage/add-to-web3@v3.0.0
  id: w3up
  with:
    path_to_add: 'dist'
    secret_key: ${{ secrets.W3_PRINCIPAL }}
    proof: ${{ secrets.W3_PROOF }}

- run: echo ${{ steps.w3up.outputs.cid }}
# "bafkreicysg23kiwv34eg2d7qweipxwosdo2py4ldv42nbauguluen5v6am"
- run: echo ${{ steps.w3up.outputs.url }}
