My React Native Journey - 10 - Sharing Wordle success on social media

 Sharing success on social media

In the Wordle game, users post their success by hiding the individual words guessed and only showing the colored squares. This lets other users understand how many tries the poster took to arrive at the correct word.

How is this done?
When the user wins, we send out a message saying he won. In addition, we show a clickable text field, called Share. On press of this text field, we execute a function called shareScore, which will return the colored rows, and also copy the same to clipboard.
For the clipboard, 

import * as Clipboard from "expo-clipboard";


Alert.alert('Hurraayy', 'You won', [{text: 'Share', onPress: shareScore}]);


Function shareScore:

const shareScore = () => {
    const textShare = rows.map(
                                (row,i) => row.map(
                                               (cell, j) => colorsToEmoji[getCellBGColor(i, j)]
                                           ).join('')
                          ).filter((row) => row).join('\n');
    Clipboard.setStringAsync(textShare)
    Alert.alert('Copied Successfully', 'Share your score on your social media')
  }

The function does this: For every i row in rows (6 rows), for every j in cell(5 columns), return the colors of the cells, joined by ''(empty string), to textShare. textShare will now look like:

Array [ "⬛🟧⬛⬛🟧", "🟩🟩🟩🟩🟩", "", "", "", "", ]

Further, filter this output to retain only the rows that have values. The resulting output in textShare
will be:

⬛🟧⬛⬛🟧
🟩🟩🟩🟩🟩

Clipboard.setStringAsync copies this into the clipboard.

You can now go and paste the clipboard contents on your social media feed, or share it with your
friends on any chat app.

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...
