Hi all! I'm very new to the DEV community. Today, I'd like to introduce data stream transfer between almost every device over HTTP/HTTPS made for use with Unix Pipe and also for browser!
What do I want to solve?
We sometimes want to transfer data between Mac, Windows, Linux, Unix, iPhone, Android... Although we have AirDrop, Google Drive, Dropbox, Slack, WhatsApp, Skype,
ssh or etc, we need to
- Find a common service used by both sender and receiver
- Install additional GUI software
- Sign up some service
- Solve NAT traversal
In addition, almost existing data transfer services are not CUI-friendly or not GUI-friendly.
So, I made a solution to the problems above. The system allows you to
- Transfer data with almost every device
- Use it without additional installation
- Use it with Unix/Linux Pipe and it's engineer-friendly
I'd like to introduce how to use the system I made.
Here is a demo to transfer
seq 100000 | curl -T - https://ppng.io/myseq
Here is a demo to transfer a 100MB file.
cat 100MB.dat | curl -T - https://ppng.io/mydata
curl https://ppng.io/mydata > mydata
You can transfer any data by using pipe. For example,
Compress & Send:
cat myfile | gzip | curl -T ...
Get & Decompress:
curl ... | zcat > myfile
Encrypt & Send:
cat myfile | openssl aes-256-cbc | curl -T ...
Get & Decript:
curl ... | openssl aes-256-cbc -d > myfile
zip -q -r - ./mydir | curl -T - https://ppng.io/mydir.zip
tar zfcp - ./mydir | curl -T - https://ppng.io/mydir.tar.gz
Here is a demo to transfer data to a browser.

This means you can transfer a file from Android/iPhone/iPad... to another device!

Infinitely transfer between every device over pure HTTP with pipes or browsers
Infinitely transfer between every device over HTTP/HTTPS
Piping Server is simple. You can transfer as follows.
# Send echo 'hello, world' | curl -T - https://ppng.io/hello
# Get curl https://ppng.io/hello > hello.txt
Piping Server transfers data to
POST /hello or
PUT /hello into
GET /hello. The path
/hello can be anything such as
/mypath/123/. A sender and receivers who specify the same path can transfer. Both the sender and the recipient can start the transfer first. The first one waits for the other.
You can also use Web UI like https://ppng.io on your browser. A more modern UI is found in https://piping-ui.org, which supports E2E encryption.
The most important thing is that the data are streamed. This means that you can transfer any data infinitely. The demo below transfers an infinite text stream with
This project is written in TypeScript.
Here are public servers. My recommendation is https://ppng.io because it has a short name.
In my policy, you can freely run the servers. I'd like to describe how to run later.
You can get engineer-friendly help from the following.
$ curl https://ppng.io/help <Help will be displayed here>
How it works
I think Piping Server is like a TURN server in Pear-to-Pear. Piping Server relays your data to another device to solve NAT traversal.
A body of POST/PUT HTTP request is passed to a body of GET HTTP response.
How to Run Piping Server
We have several ways to run Piping Server. I'd like to introduce one by one.
Push [Deploy to Heroku] button in https://github.com/nwtgck/piping-server.
Portable Binary Executable
The following commands make a Piping Server run on http://localhost:8888.
wget https://github.com/nwtgck/piping-server-pkg/releases/download/v0.8.7/piping-server-macos chmod +x piping-server-macos ./piping-server-macos --http-port=8888
You can also find other platform releases in GitHub Releases in https://github.com/nwtgck/piping-server-pkg. The portable executables are produced by zeit/pkg.
docker run make a Piping Server run on http://localhost:8888.
docker run -d --restart=always -p 8888:80 nwtgck/piping-server --http-port=80
The following commands make Piping Server run on http://localhost:8888.
# install npm install -g piping-server # run piping-server --http-port=8888
Possibility of Data Transfer over HTTP
I'm conducting an experiment to reveal how many data can be transferred over HTTP.
I started the experiment 55 days and 7 hours ago and over 1000 terabyte data were transferred.
The method of the experiment is as follows.
cat /dev/urandom | curl -T - localhost:8888/rand
curl localhost:8888/rand > /dev/null
Transfer Speed Compared with Go
Here is a simple comparison in transfer speed between TypeScript/Node.js and Go implementations. As a result of the videos, there seem to be almost no differences.

Thank you very much for reading. Have a wonderful day!

Your tests may be limited by
/dev/urandom. What about using
ddalso allows you to control the block size.) You can test the speed of input data with pv.
Also the CPU usage of the server needs to be considered too, otherwise CPU used by
curland other tools is competing and not taken into account.
Thank you very much for your smarter suggestion! I thought the comparison was too simple. When I tried another speed comparison, I'll use your suggestion, and server, senders and receivers should be run probably in different machines, considering CPU usages.
This is very slick Ryo and I enjoyed the samples you shared in this post. Although it looks like one GIF for the 100MB file is not actually doing that, it would be fun to see that as well.
Have you tried running this inside of a serverless function like AWS Lambda?
Thanks! I replaced the GIF for 100MB file with the proper one.
I haven't tried. I don't think Piping Server is designed for serverless or FaaS.
In my comprehension, a serverless function should be stateless. On the other hand, Piping Server has states in each path. Piping Server doesn't store data in storage or database. Data passed from one device to another one are only on memory. That's why I think Piping Server has states.
Piping is great for one way transfer! For two way similar services are serveo.net or ngrok.com.
Thanks! I've never known serveo.net, it's so useful, no-install, no-signup!
I think that a benefit of Piping Server, which serveo and ngrok might not have is allowing users to transfer data even from Android/iPhone smartphones with pre-installed browsers.
Yep, Piping Server is best for http upload/download where data only needs to flow in one direction. serveo is useful if you need two way communications for any reason.
Yes! I agree with you. serveo is so useful, it allows me to use it with only
sshand communicate another device in two way. I knew serveo because you told me it. Thank you very much!
Here is an article which describes two-way communication via Piping Server with only
curl. The article was written by another Japanese not me. In it, Piping Server is used like serveo.
