IPFS backend for sending and getting file from the ipfs system without deploying local node
//Required modules
const ipfsAPI = require('ipfs-api');
const express = require('express');
const fs = require('fs');
const app = express();
//Connceting to the ipfs network via infura gateway
const ipfs = ipfsAPI('', '5001', {protocol: 'https'})
//Reading file from computer
let testFile = fs.readFileSync("PATH_OF_FILE");
//Creating buffer for ipfs function to add file to the system
let testBuffer = new Buffer(testFile);
//Addfile router for adding file a local file to the IPFS network without any local node
app.get('/addfile', function(req, res) {
ipfs.files.add(testBuffer, function (err, file) {
if (err) {
//Getting the uploaded file via hash code.
app.get('/getfile', function(req, res) {
//This hash is returned hash of addFile router.
const validCID = 'HASH_CODE'
ipfs.files.get(validCID, function (err, files) {
files.forEach((file) => {
app.listen(3000, () => console.log('App listening on port 3000!'))
