way-home is a websocket based reverse proxy with google auth. The main purpose is to make home running servercies (iot, web-UI of apps,...) accessible from a public address with security in mind and no need to expose internal network directly to the outside world (punches practically any nat).
The solution is in 2 parts a server and a agent client.
It is a the program that needs to run on the "home" network. It connects (after authorization) to the server with a websocket, and sends the configured forwarded "web apps" to the server which will handle the routing.
Needs to run on a publicly accessible address. It handles all connections and routing, and authentication, and runs a small web ui for user managment and links. When you access the the server web app, you will first have to log in (be sure to add your email to the config). Then depending on the permissions set on the agent client it will list the "apps". The "apps" are accessed by going to [app-id].your-server-domain.tld if you are logged in (session created), the server will proxy the requests to the target port on the agent.
- A hosting server able to run node (ie: aws, gce, bare metal) with open 433 port(plain http is not advised, should be https).
- A direct and wildcard domain pointing to the hosting server (proxy.mydomain.tld and *.proxy.mydomain.tld)
- HTTPS reverse proxy (nginx, ALB, ...)
- HTTPS Certificate for wildcard and direct domain (ie: proxy.mydomain.tld and *.proxy.mydomain.tld)
- Some sort of process/service manager on the hosting machine to keep the service running (ie: supervisor, pm2, systemd, ...)
- Set up a google oauth in google console. Allowed callback should be:
https://[domain]/googleCallback
- Install the package
npm install -g way-home - Create config in the desired folder
way-home server --create-server-config(it will create a blank configuration ) - edit the configuration (see: server configuration)
- set up the a service managment to run
way-home serverin the directory you created the config or use--server-config-file=[path-to-config] - set up your https revese proxy to point to the port of the server
- Check if everything works by connecting to the domain
- Install the package
npm install -g way-home - Create config in the desired folder
way-home client --create-client-config(it will create a blank configuration ) - edit the configuration (see: client configuration)
- set up the a service managment to run
way-home clientin the directory you created the config or use--client-config-file=[path-to-config]

}For development the main thing is you wil have to edit your hosts file to make it work in development. Pick some domain and point it to localhost, use that domain in config files. For development just use isSsl: false. To start the development use yarn dev server and yarn dev client. Can be run in the same command too: yarn dev server client. The dev env is set up in such a way that modification will trigger re-compile and restart. For faster restarts if you are only working on the websocket router you can skip nextjs by yarn dev server --skip-next
First and foremost, your server should use https, otherwise the communication between agent and server will be vulnerable to MIM. Whenever possible use session mode, using basic or open should be considered unsecure. To make everything work, there are some direct http request parsing, which although in most cases should be ok there might be some flaw that I have missed. Agent configuration contains a authentication key that is used to authenticate the agent with the server. It should be considered very sensitive, if "stolen" one could attempt to spoof an agent, but since only one agent with same id can be connected, they will be disconnecting eachother, should be easily noticable from logs. For basic auth, the password is stored on the client config in clear text. As mentioned before basic should be considered unsafe, but when I have some time I will update to store a hashed value.
This was a hobby project of mine from few years ago, that I decided to make public. I have updated the majority of the libs but there is still cleanup to do. There might be some major flaws that I have failed to notices, use at your own risk. It obviusly comes with no warranty or anything of sorts. There are still some bits needing of cleaning.
