Simulate different times/dates in your app

/in /by

If you want to test your app with different times you don’t need to change your computer time (what can lead to unexpected consequences), instead you can simple open a terminal and launch your app with faketime.

faketime -f "@2049-01-11 17:50:00" firefox

Replace all your files indented with 4 spaces to 2 spaces

CordovaError: Requirements check failed for JDK 1.8 or greater

/in /by

If you have a Cordova Error after updating to Ubuntu 18.04, the easiest way to resolve this issue is removing openjdk-11 and reinstalling openjdk-8.

sudo apt purge openjdk-11-jdk-headless openjdk-11-jre-headless
sudo apt install openjdk-8-jdk

There is not support for the new java versions yet in Cordova/Android (at the post date)

Simple local development environment for web apps

/in /by
  1. Open your app working directory
    • There you should have at least index.html
  2. Launch http-server in your terminal
    • If you haven’t installed it yet: npm install http-server -g
  3. Launch chromium-browser --disable-web-security --user-data-dir=/tmp/something in your terminal to allow all origins (temporary ignore  CORS mechanism )
    • Make sure you don’t have other instances open: pkill -f chromium
  4. Type in the address bar one of the address from your http-server info to access to your app

Note: Use Chromium without security just with your own code for testing and development, do not browse with it and beware about using third-party software in your code.
