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.
npm install --save ipfs-mini
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' }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.
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.
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.
