cross-device testing over wi-fi

the host machine must serve website at 0.0.0.0
- this makes the website available to the devices in the same network outside the machine OS
- jekyll
```
  bundle exec jekyll serve --host 0.0.0.0
```
- angular
```
  ng serve --host 0.0.0.0
```
this can be accessed by a different device on the same router network through a browser by knowing the local IP address of the machine that’s serving the website
```
  http://(local-ip-of-machine):(default-port)

  # example
  http://192.168.0.5:4000
```
0.0.0.0 still makes the website available on localhost:default-port locally on the machine
- jekyll: 0.0.0.0:4000
- angular: 0.0.0.0:4200
default port works fine unless multiple processes try to serve through the same port
- the old processes might have to be killed before the new one is available to the default port
- alternative is to serve website a different port on 0.0.0.0
- jekyll
```
  bundle exec jekyll serve --host 0.0.0.0 --port 5310
```
- angular
```
  ng serve --host 0.0.0.0 --port 4800
```
different browsers across various devices can be used to test the website as long as they are in the same router network
