## 🏗 Installation

```bash
npm install @oceanprotocol/react
```

## 🏄 Usage

First, wrap your whole app with the [`Web3Provider`](src/providers/Web3Provider) and the [`OceanProvider`](src/providers/OceanProvider).

### 1. Providers

```tsx
import React, { ReactNode } from 'react'
import { Web3Provider, OceanProvider, Config } from '@oceanprotocol/react'

const config: Config = {
  nodeUri: '',
  aquariusUri: '',
  ...
}

export default function MyApp({
  children
}: {
  children: ReactNode
}): ReactNode {
  return (
    <Web3Provider>
        <OceanProvider config={config}>
          <h1>My App</h1>
          {children}
        </OceanProvider>
      )}
    </Web3Provider>
  )
}
```

The `OceanProvider` requires a Web3 instance to be passed as prop so you can replace the basic [`Web3Provider`](src/providers/Web3Provider) with whatever component/library/provider returning a Web3 instance.

### 2. Hooks

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

```tsx
import React from 'react'
import {
  useWeb3,
  useOcean,
  useMetadata,
  useConsume
} from '@oceanprotocol/react'

const did = 'did:op:0x000000000'

export default function MyComponent() {
  // Get web3 from built-in Web3Provider context
  const { web3 } = useWeb3()

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

  // Get metadata for this asset
  const { title, metadata } = 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: {web3.utils.fromWei(metadata.main.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:

```bash
npm start
```

## ✨ Code Style

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

```bash
# 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`](https://github.com/developit/microbundle) into:

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

```bash
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 `master` 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
- Git tag push will trigger Travis to do a npm release

For the GitHub releases steps a GitHub personal access token, exported as `GITHUB_TOKEN` is required. [Setup](https://github.com/release-it/release-it#github-releases)

### 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:

```bash
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
```
