My React Native Journey - 4 - Understanding the App.JS file

Understanding the App.js file

Majorly, a single JS file contains four sections of code elements.

First, import statements to import required components from react, react-native and other modules.

Second, the App function written as
const App = () =>{}
read as Component App is of type function and whatever the function returns is rendered as a React Element.

Third, use a component called Stylesheet to create a CSS abstract 

const styles = Stylesheet.create({})
read as tell StyleSheet to create style objects with an ID, and return it to const styles.
These IDs are further used to reference instead of rendering.

Fourth and Finally, export default app is used to export a single class, function or primitive from a script file.


Now. with this background, I decide to follow this video to build a wordle clone.

Reading a pre-populated sqlite database using react native with expo..

Image
I recently needed to read an existing sqlite database, and return its contents to the react native front-end on an android emulator.  I  read several related posts on the subject but they all give examples of console logging, never returning.  I faced quite some difficulties, and hence decided to create this post as a blog. Hope it helps someone who comes here looking for a solution. Usually, there are two main issues that you would face. One, you would notice that simply opening a database and fetching won't work. You need to copy the local database to an internal document store and then use that database. Second, you would notice that there is no way of 'returning' the value of  a variable in the traditional sense of the term. You must handle it within the async function itself. So follow me for the solution.  Step 1. Create the root folder. From the terminal in the root folder, create the react native app with expo using : expo init newApp Choose the blank te...

React Hooks - useState Vs useRef (An explanation)

Image
I have tried to provide a brief  flowchart representation of how useState, useEffect and useRef work. The source for this explanation is from  WebDev Simplified's you tube channel . Suppose you wanted to show a name field and a count field to count how many times you updated the name field.  The diagram below shows the code (not focussing too much on the syntax and stuff), how one would normally do it, and the challenges/details of how react will work in each case. In general, on the left part of the diagram, I have provided the code, the middle part displays the contents of the form as things happen, and have included some explanation on how it all works on the right part.  Hoping the picture is self-explanatory.  The biggest usecase for useRef is to refer to the elements inside of the HTML. Each element inside the focument has a 'ref' attribute which can be set to anything. Most common use is to set focus to a certain element in the DOM. In the pictorial below...
