# instapaper

A TypeScript client for the [Instapaper API](https://www.instapaper.com/api).

## Installation

```bash
npm install instapaper-ts
```

## Authentication

Instapaper uses OAuth 1.0a with xAuth. You'll need a **consumer key and secret** from Instapaper, plus your account **username and password**, but only to perform a one-time token exchange. After that, store the token and use it directly for all future requests.

### 1. Exchange credentials for a token

Call `Instapaper.fetchToken(...)` to authenticate with your username and password. This performs the xAuth token exchange and returns the result. Once you have the token, persist it so you don't repeat the exchange on every run.

```typescript
import { Instapaper } from "instapaper";

const token = await Instapaper.fetchToken({
	consumerKey: "your_consumer_key",
	consumerSecret: "your_consumer_secret",
	username: "your@email.com",
	password: "your_password",
});

// Persist the token for future use
await saveToken(token); // e.g. write to disk, a secrets store, a session cookie etc.
```

### 2. Initialise from a cached token

Once you have a token, you can then use it to instantiate the Instapaper client. This allows you to reuse your token in different parts of your app, without having to reauthenticate every time with your username and password.

```typescript
const token = await loadToken();

const client = new Instapaper({
	consumerKey: "your_consumer_key",
	consumerSecret: "your_consumer_secret",
	token,
});
```
