I am trying to upload a file to ipfs using ejs app. I have go to a lot of posted problems but i have not seen a problem like i am getting.
when we use ipfs.add() method with a simple string "Hello World" it still worked for others but in my case it is throwing an error.
This is the code where I try to upload the file:
upload file code (upload.ejs):
<div class="card">
<h5 class="card-header">Upload Document to IPFS</h5>
<div class="card-body">
<form action="/ipfs" method="POST" enctype="multipart/form-data">
<div class="row">
<div class="form-group col-10">
<input type="file" name="filetoupload" class="form-control">
</div>
<div class="form-group col">
<button type="submit" class="btn btn-primary">UPLOAD</button>
</div>
</div>
</form>
</div>
</div>
app.js file:
const fs = require('fs')
const express = require("express");
const cors = require('cors');
const path = require('path');
const fileupload = require('express-fileupload');
const { create } = require("ipfs-http-client");
const app = express();
app.use(fileupload());
app.use(cors());
app.use(express.static(path.join(__dirname,'public')));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.set('views', './views');
app.set('view engine', 'ejs');
app.listen(8010, () => {
console.log("Application started and Listening on port 8010");
});
app.get("/", (req, res) => {
res.render("home");
});
const ipfs = create({host:'localhost',port:6001,protocol:'http'});
app.get("/ipfs/:hashcode", async function(req, res) {
const hashcode = req.params.hashcode;
res.setHeader('Content-Type','application/json');
let result = false;
if (hashcode) {
const stream = ipfs.cat(hashcode);
let data = ''
for await (const chunk of stream) {
// chunks of data are returned as a Buffer, convert it back to a string
data += chunk.toString()
}
result = true;
res.json({
'success': result,
'data': data
});
} else {
res.json({
'success': result,
'data': ''
});
}
});
app.post("/ipfs", (req, res) => {
const file = req.files.filetoupload;
const filename = req.files.filetoupload.name;
console.log("here")
const filepath = 'files/' + filename;
file.mv(filepath, async(err) => {
if(err){
console.log("ERROR: Upload File Error!");
return res.status(500).send(err);
}
const hashcode = await addFile(filename,filepath);
console.log("HHHHAAAAAAAAAAAAAAAAAAASSSSSSSSSSSSHHHHHH...."+hashcode); // here i am gettin undefined
fs.unlink(filepath, (err => {
if(err) console.log(err);
}))
res.render("upload",{filename, hashcode});
})
});
// ipfs api: https://github.com/ipfs/js-ipfs/blob/master/docs/core-api/FILES.md#ipfsadddata-options
const addFile = async(filename,filepath) => {
try {
const file = fs.readFileSync(filepath);
console.log("------------------(Here Before await)--------------------\n");
// const added = await ipfs.add(file);
// const added = await ipfs.add({path: filename, content:file});
const added = await ipfs.add("hello world"); // here i am getting error
console.log("------------------(Here After await)--------------------\n"); // after error this lone is ignored
// console.info(added);
return added.cid.toString();
} catch (err){
console.log(err);
}
}
I am getting in addFile() method in app.js const added = await ipfs.add("hello world");
Docker Compose file

Error Snap (Updated): The error snap is updated after some suggestion of @discordian @discordian trace that i have no docker-compose, but after that i am still getting the error.
