Abstract

Hello everybody, It’s candle.

This time, we will solve the problem that using simulator is going to slow down when debugging on the Google Chrome

Anyway, It is solved in a simple way. we use Chromium instead of Google Chrome.

Premise

React development environment has been established

Try debugging

Start with the react-native project at first.

After starting up, press cmd + d on the simulator.
A menu is displayed, You choose “Debug JS Remotely”

enabledebugjsremote

Google Chrome will launch.

googlechromedebugwihndow

Unfortunately, I don’t know how to make Chromium the default browser,
first, start up with Google Chrome and copy the URL to Chromium.

You copy the URL and stat up Chromium.
Paste the copied URL and move.

chromeiumdebugwindow

“Status: Another debugger is already connected” appears.
This warning is displayed because it is connected to google chrome.

So you quit Google Chrome

An error will occur on the simulator side, but you would reload it with cmd + R, it will move normally to Chromium side.

simulatordebugerror

Chromium connected to the simulator successfully

chromiumconnectsuccess

Reusult

In my case, m simulator move fast.
