testproxy v1.3.4

testproxy

Test your locally running websites on other devices

If you are running a webserver as localhost, with a local webserver or in a virtual machine like VirtualBox VMware, Vagrant or Docker, you can't always access this webserver from other computers or mobile devices.

Testproxy will create a proxy to this local webserver and makes them available to other devices on the same (Wi-Fi) network. All without any configuration.

Running

Assuming http://localhost:8080/ is working in your local browser but nowhere else:

npx testproxy http://localhost:8080/

The first time it will ask you to install testproxy. Press enter to proceed.

If the command npm is not found, you have to install the Node.js and npm combination. Go to https://nodejs.org/ and install Node.js. Then type the command above again.

Testproxy will respond with something like:

Listening on http://192.168.0.93:6239

And it will show a QR code.

Type the URL in the browser on your mobile device or scan the QR code and the website will appear. Make sure the computer and other device are connected by the same (WiFi) network.

Type CTRL-C to stop testproxy.

Parameters

npx testproxy <url> [-l<port>] [-noqr]

url: the same url as you use for local development

port (optional): the port to listen to

-noqr turn off showing the QR code

Example

To make your local website test.mycompany available on port 9000 without showing the QR code:

npx testproxy http://test.mycompany/ -l9000 -noqr

You can connect different domain names to different port numbers at the same time. Testproxy does not work with https connections.

Highly secured WiFi

Some WiFi networks are highly secured and prevent you from accessing other computers on the same network. Here are some solutions to this problem:

• Connect the host computer and the other computer or mobile to the same guest Wi-Fi network.
• Configure one device as a hotspot and connect your other device to this hotspot.
• Use another, unprotected Wi-Fi network for development and test purposes, installing a dedicated Wi-Fi access point if needed.
