🏗 Installation

npm install @oceanprotocol/react

🏄 Quick Start

1. Add Provider

First, wrap your whole app with the <OceanProvider />.

2. Use Hooks

Then within your component use the included hooks to interact with Ocean's functionality. Each hook can be used independently:

import React from 'react'
import {
  useOcean,
  useMetadata,
  useConsume,
  usePublish
} from '@oceanprotocol/react'

const did = 'did:op:0x000000000'

export default function MyComponent() {
  // Get Ocean instance from built-in OceanProvider context
  const { ocean, web3, account } = useOcean()

  // Get metadata for this asset
  const { title, metadata, price } = useMetadata(did)

  // publish asset
  const { publish, publishStep } = usePublish()

  // consume asset
  const { consume, consumeStep } = useConsume()

  async function handleDownload() {
    await consume(did)
  }

  return (
    <div>
      <h1>{title}</h1>
      <p>Price: {price}</p>

      <p>Your account: {account}</p>
      <button onClick={handleDownload}>
        {consumeStep || 'Download Asset'}
      </button>
    </div>
  )
}

🦑 Development

The project is authored with TypeScript and compiled with tsc.

To start compiler in watch mode:

npm start

✨ Code Style

For linting and auto-formatting you can use from the root of the project:

# auto format all ts & css with eslint & stylelint
npm run lint

# auto format all ts & css with prettier, taking all configs into account
npm run format

👩‍🔬 Testing

🛳 Production

The build script will compile src/ with microbundle into:

1. CommonJS module
2. ES module
3. UMD build

npm run build

⬆️ Releases

Releases are managed semi-automatically. They are always manually triggered from a developer's machine with release scripts.

Production

From a clean main branch you can run any release task bumping the version accordingly based on semantic versioning:

• To bump a patch version: npm run release
• To bump a minor version: npm run release -- minor
• To bump a major version: npm run release -- major

Every task does the following:

• bumps the project version in package.json, package-lock.json
• auto-generates and updates the CHANGELOG.md file from commit messages
• creates a Git tag
• commits and pushes everything
• creates a GitHub release with commit messages as description
• GitHub release will trigger a GitHub Actions workflow to do a npm release

For the GitHub releases steps a GitHub personal access token, exported as GITHUB_TOKEN is required. Setup

Pre-Releases

Usually from a feature branch you can release a develop version under the next npm tag.

Say the current version is at v1.1.0, then to publish a pre-release for a next major version v2.0.0-beta.0, do:

npm run release -- major --preRelease=beta --npm.tag=next

# consecutive releases, e.g. to then get `v2.0.0-beta.1`
npm run release -- --preRelease

# final version, e.g. to then get `v2.0.0`
npm run release -- major

📜 Changelog
