A JavaScript interface to the [Hud.ai API][hud-ai-docs-link]. To get started
install via npm:

```bash
npm install --save hud-ai
```

## Getting Started

First, you'll need to register a client application. This can currently only be
done by [reaching out to the engineering team](mailto:engineering@hud.ai).

### Single Page Apps

```js
const HudAi = require('hud-ai');

const client = HudAi.create({
  clientId: 'CLIENT_ID',
  redirectUri: 'http://www.example.com/oauth/callbacks/hud-ai'
});

// Send the user to the authorization URL, where they can choose to grant your
// app permissions to access the service on their behalf (if permission has
// already been given, they'll automatically be redirected)
window.location = client.getAuthorizeUri('token');

// token will be returned as the query param `authToken` to your redirect URL
const querystring = require('query-string');
const parsed = querystring.parse(location.hash);
client.setAccessToken(parsed.access_token);
```

NOTE: The process of token retrieval will need to be performed again when the
token becomes invalid (they're currently valid for 30 days).

### Server Applications

Because servers can be trusted to keep a secret, setup is much more
straightforward.

Client Authentication:

```js
const HudAi = require('hud-ai');

const client = HudAi.create({
  clientId: 'CLIENT_ID',
  clientSecret: 'CLIENT_SECRET'
});
```

Acting on behalf of a user:

```js
const redirectUrl = client.getAuthorizeUri('code');

// Send the user to the authorization URL, where they can choose to grant your
// app permissions to access the service on their behalf (if permission has
// already been given, they'll automatically be redirected)

// the code to exchange will be returned as the query param `code` to your
// redirect URL
const querystring = require('query-string');
const parsed = querystring.parse(location.search);
client.setAuthorizationCode(parsed.code);
```

### Parameters

```

## Resources

### Notes
