A super tiny module for querying an IPFS node, that works in the browser and in Node. Only **2.76 kB** compressed!

This module was inspired by [`browser-ipfs`](https://github.com/pelle/browser-ipfs).

## Install

```
npm install --save ipfs-mini
```

## Usage

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

ipfs.add('hello world!').then(console.log).catch(console.log);

// result null 'QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j'

ipfs.cat('QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j', (err, result) => {
console.log(err, result);
});

// result null 'hello world!'

ipfs.addJSON({ somevalue: 2, name: 'Nick' }, (err, result) => {
console.log(err, result);
});

// result null 'QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j'

ipfs.catJSON('QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j').then(console.log).catch(console.log);

// result null { somevalue: 2, name: 'Nick' }
```

## About

A very simple module for querying an IPFS node. This module works for both `nodejs` and in the browser. It's extremly light, `<3 kB` when compressed.

This module uses the `js-ipfs-api` module for the adding operations on nodejs. However, in the browser, it uses a very light `FormData` `Blob` handling proceedure which was designed by Pelle Braendgaard, in his `browser-ipfs` module.

## Examples

An example of the module in use for the browser, can be found in [./example](./examples).

Inside is a single, no configuration required, HTML file using the `ipfs-mini` module.

## Browser Usage

`ipfs-mini` is completely browserifiable and webpack ready. The main export found in our distributions [dist](./dist) folder is `IPFS`. There you will find two builds of `ipfs-mini`, one compressed and minified `ipfs-mini.min.js` and one uncompressed `ipfs-mini.js`.

```



<script type="text/javascript">
var ipfs = new IPFS({ provider: 'ipfs.infura.io', protocol: 'https' });

// ...

```

## API Design

### constructor

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Intakes a single provider object, outputs an `ipfs` instance.

**Parameters**

- `provider` **Object** a single provider object, see `setProvider` for more details

Result output `ipfs` **Object** instance.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

ipfs.cat('QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j', (err, result) => {
console.log(err, result);
});
```

### setProvider

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Sets the IPFS instance provider.

**Parameters**

- `provider` **Object** a single provider object.

default: `{ host: 'localhost', port: 5001, protocol: 'http', base: '/api/v0' }`

No result output.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS();

ipfs.setProvider({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

ipfs.cat('QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j', cb);
```

### add

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Queries `/add` and adds a single String or Buffer data to IPFS, returns an IPFS hash.

**Parameters**

- `input` **String|Buffer** the input data to be added to IPFS.

Result output `ipfsHash` **String**.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

ipfs.add('hello world!', (err, result) => {
console.log(err, result);
});

// result null 'QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j'
```

### addJSON

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Queries `/add` and adds stringified JSON to IPFS, returns a single ipfs hash.

**Parameters**

- `input` **Object** the input data to be added to IPFS.

Result output `ipfsHash` **String**.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

ipfs.addJSON({ somevalue: 2, name: 'Nick' }, (err, result) => {
console.log(err, result);
});

// result null 'QmTp2hEo8eXRp6wg7jXv1BLCMh5a4F3B7buAUZNZUu772j'
```

### cat

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Queries a `/cat` request, returns data as a String.

**Parameters**

- `ipfsHash` **String** the ipfs hash string.

Result output `data` **String**.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });

console.log(err, result);
});

// result null 'Hello world!'
```

### catJSON

[index.js:ipfs-mini](../../../blob/master/src/index.js "Source code on GitHub")

Queries a `/cat` request, returns data as a parsed JSON object.

Result output `data` **Object**.

```js
const IPFS = require('ipfs-mini');
const ipfs = new IPFS({ host: 'ipfs.infura.io', port: 5001, protocol: 'https' });
