JPFS is a simple JavaScript module for content-addressable storage and retrieval of arbitrary data by its hash, in Node.js or the browser.
It's like IPFS, but all data comes from a single peer, so it's not good for large data like videos. But it also works without any configuration or surprises, even in the browser, with a simple API.
$ npm install jpfs
or:
$ npm install -g jpfs// server.js
let { serve } = require('jpfs')
let { hash, close } = serve('hello world')
console.log(hash) // 'b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9'
// close() to stop serving// client.js
let { get } = require('jpfs')
async function main() {
let data = await get(
'b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9'
)
console.log(data) // 'hello world'
}
main()# server:
$ cat mydata.txt | jpfs
# outputs hash
# client, on another machine:
$ jpfs <hash>
# outputs contents of mydata.txt
