ipfs-mini

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.

Install

npm install --save ipfs-mini

Usage

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.

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 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.

API Design

constructor

index.js:ipfs-mini

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.

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

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.

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

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.

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

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.

const IPFS = require('ipfs-mini');
