The only answers I can find in my research cover uploading multiple files from a directory on a PC. That is not what I'm trying to do. I'm trying to create a directory in ipfs and then add new files to that directory using js-ipfs with pure javascript only, generally one file at a time.
I conceptually understand that a directory in ipfs is simply another file. But I don't understand how to create that directory (file) and add other files to it for later retrieval, particularly with js-ipfs and pure javascript code.
I am implicitly not using node.js, therefore neither react, angular or vue either.
This works for a single file with no directory on ipfs:
<!DOCTYPE html>
<html>
<head>
<script src=".min.js"></script>
</head>
<script>
document.addEventListener('DOMContentLoaded', async () => {
const nodeId = 'ipfs-' + Math.random()
const node = await Ipfs.create({ repo: nodeId })
console.log("Your node: " + nodeId)
window.node = node
const status = node.isOnline() ? 'online' : 'offline'
console.log(`Node status: ${status}`)
async function addFile () {
for await (const { cid } of node.add('Some file content!')) {
console.log('successfully stored', cid)
cidhash=cid.toBaseEncodedString()
console.log(cidhash)
}
}
addFile()
})
</script>
<body>
</body>
</html>
How to make this work to create a directory and add a file to it initially, then add another file to the created directory later (pseudocode-ish)?
async function addFile () {
for await (const { directory, filename } of node.add('/someDirectory/someFilename','Some file content!')) {
console.log('successfully stored', directory, filename)
console.log(directory, filename)
}
}

- I thought it was not possible to add or read files using javascript – Thanveer Shah Commented Jun 30, 2020 at 0:38
- @ThanveerShah ipfs is a distributed filesystem. You are correct that you cannot create a normal local file in browser JS. – Jared Smith Commented Jun 30, 2020 at 0:39
- @JaredSmith, I'll surely look into this , thanks. Also this might be out of topic but is it possible to read a zip file from the project directory using this? – Thanveer Shah Commented Jun 30, 2020 at 0:41
- 1 @ThanveerShah no. – Jared Smith Commented Jun 30, 2020 at 0:41
- @ThanveerShah There is a script source CDN available to bring Buffer to the browser, but it is very flakey (wzrd.in/standalone/buffer). Either way, that's not what I'm trying to do. I want to create a file with text content, but I want to put that file in a directory created on IPFS. I'm not trying to upload a local directory of files. – Dshiz Commented Jun 30, 2020 at 0:49

Reset to default 4Reading through the js-ipfs documentation, I finally found the answer.
To only create a directory:
await ipfs.files.mkdir('/my/beautiful/directory')
Full working example to create a directory path and add a file to it at the same time:
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.jsdelivr/npm/ipfs/dist/index.min.js"></script>
</head>
<script>
document.addEventListener('DOMContentLoaded', async () => {
const nodeId = 'ipfs-' + Math.random()
const node = await Ipfs.create({ repo: nodeId })
console.log("Your node: " + nodeId)
window.node = node
const status = node.isOnline() ? 'online' : 'offline'
console.log(`Node status: ${status}`)
//create a variable with the directory path '/my/beautiful/directory'
// and a file 'awesomesause.txt' with the content 'ABC'
var files = [{
path: '/my/beautiful/directory/firstfile.txt',
content: 'ABC'
}]
addFile(files) //add the first file
//update the 'files' variable to add another file to the directory path '/mybeautiful/directory' in ipfs
files = [{
path: '/my/beautiful/directory/secondfile.txt',
content: 'DEF'
}]
addFile(files) //add the sectond file
//function to add the files
async function addFile (files) {
for await (const result of node.add(files)) {
console.log(result)
}
}
})
</script>
<body>
</body>
