 There are multiple method to format and manipulate Date and Time. Generally speaking the most common libraries used to manipulate dates are Day.js, Luxon, Moment, and Date-fns. Moment developers have discouraged developers to use moments at this time due to not being built for modern JavaScript era. Day.js Installation: npm install dayjs --save Header import: import calendar from 'dayjs/plugin/calendar' import dayjs from "dayjs"; Usage example: dayjs.extend(calendar) dayjs().calendar(dayjs( '2008-01-01' )) dayjs().calendar( null , { sameDay : '[Today at] h:mm A' , // The same day ( Today at 2:30 AM ) nextDay : '[Tomorrow at] h:mm A' , // The next day ( Tomorrow at 2:30 AM ) nextWeek : 'dddd [at] h:mm A' , // The next week ( Sunday at 2:30 AM ) lastDay : '[Yesterday at] h:mm A' , // The day before ( Yesterday at 2:30 AM ) lastWeek : '[Last] dddd [at] h:mm A' , // Last week ( Last Monday at 2:30 AM ) sam

We use StyleSheet in almost all components. Generally there are three different approaches to changing component layout with React Native: Direct layout change in the component (e.g. text field) Create a StyleSheet section in each page Create a Global StyleSheet and reference in each component Personally speaking, I do not recommend the first 2 options due to: maintenance and inconsistency approach in design between different components harder to transfer to a new project. with GlobalStyles, you can put on a separate windows for easy view and update as you work on different component apply the dark/light theme to the component directly through GlobalStyles without having to customize it for each page Theme - Dark and Light theme with React Native with iOS, Android, Web, etc. Warning: if you use Expo Debugging, the system will default to Light theme (at least on iOS). Remove Remote Debugging if you want the Dark Theme to show up. In your Navigagor, apply the theme: const scheme = useCol

This page will capture all issues related to Date and React Native mobile app development. Will add more as I go through the development cycle.  I will play around with Javascript for a bit before switching to TypeScript.  Some of the information below might not be following the best practice as I just started the development process. Will update as I learn more about React Native + Javascript. Storing Date object in AsyncStorage You can store Date object directly into AsyncStorage. Generally in other programming language, you can store the Date object directly in a data storage. However, with React Native, you will get the the Debug Console warning on Expo Go if you do so. I recommend using JSON.stringify() command below to store the date object. Please follow the instruction below.  On the side note, you can also store millisecond and use the date toString option but it is not recommended. I would recommend using stringify command as it will store using the toISOString() which is the

Setup Debugging on Visual Studio Code Make sure you have expo-cli installed globally - if not, run: npm install -g expo-cli Open Visual Studio Code Click: Control + Shift + D to Open Run and Debug window If you have never set this up before, select the Create a launch.json file under Run and Debug button If you had a launch.json file before, select the option Add Config (your workspace name) Select React Native Click Debug Application Click Exponent Select Application in Direct mode Select Tunnel  Save the file launch.json file should be ready Start the debug session Note: if you are missing some library, Expo will remind you to install. Follow the instruction if required Re-open Run and Debug window if not yet opened (Control + Shift + D to open) Select "Debug in Exponent" on the drop down list box Click F5 to start the debugging session Expo QR Code window should show up on the right handside Open Expo Go (download if not yet installed Scan the code with your camera Select
