Cross Origin Resource Sharing (CORS) was designed mainly to access resources from cross domains. Cross-domain policy does not apply to Cordova, so we don't have to think much about when testing on a device:
While running the same app on a browser it might gave a CORS error while accessing resources from the cross domain. When you run the ionic serve command you will see this issue. There are four methods to bypass it:
- Disable Chrome security
- Browser extension
- Proxy server
- The easiest and most convenient way is to run the application in Google Chrome with flag: --disable-web-security:
$ google-chrome -disable-web-security $ chromium-browser ...
