wtf is lanview-cli?

LanView is a command line tool that solves a common annoyance for web developers: testing a website or app on a phone while it is still running on your own computer. Normally you would have to find your computer's local network address and type it into your phone's browser by hand, and any part of your app that talks to a backend using the word localhost simply breaks on a phone, since the phone treats localhost as itself rather than as your computer. Running the tool starts three things at once on your machine. First it automatically finds your computer's local network address without any manual lookup. Second, it starts a small local proxy server that sits in front of both your frontend, such as a React or Vite app, and your backend, such as an Express or Django server, and routes requests to whichever one they belong to based on the web address path. Third, it turns the final address into a QR code drawn right there in your terminal window, so you just scan it with your phone's camera to open the app. Because both the frontend and backend are reached through this one proxy, your code does not need any special configuration for mobile testing, and relative paths like fetch of slash api slash data work the same on desktop and on a phone. The tool works entirely over your local WiFi network with no cloud service, account, or internet tunnel involved, so nothing about your project leaves your own network. It also supports proxying WebSocket connections, which keeps live reload features working while you test on a phone. Installation is done through npm, either as a global package or by running it directly with npx, and it can also be installed from source by cloning the repository and linking it locally. The default setup expects a frontend on port 3000 and a backend on port 5000, but all of the ports and the API path prefix can be customized with command line options when you run the tool.
