Started	https://dev.to/salesforcedevs/building-a-kotlin-mobile-app-with-the-salesforce-sdk-part-1-getting-started-4o4o	Building a Kotlin Mobile App with the Salesforce SDK Part Getting StartedNowadays users expect mobile apps to act as counterparts to the websites and platforms they use on the web Mobile applications give users the ability to carry their data with them granting them the flexibility to interact with platforms wherever they go This usability makes sense and we are all familiar with it Developing a mobile experience that s seamlessly integrated with the functionality of your website can be intimidating For starters how should you store and retrieve data if the mobile app loses connectivity What happens when two mobile users try to update the same data at the same time How can you just make sure your app s data is in sync given that it has limited storage space In this series we ll take a look at the Salesforce Mobile SDK a toolkit that addresses many of these technical challenges for developers building apps for Android or iOS The Salesforce Mobile SDK handles data synchronization offline storage notifications authentication and many more essential details To highlight some of these features we ll build an app that accesses real Salesforce data On the Salesforce end we ll set up an org with a pre populated app that uses custom objects In this first post of the series we ll cover how to get our mobile app to display our records In Part Two we ll cover how to create and update records in our list Finally in Part Three we ll learn how to work with the SDK and the Salesforce APIs to synchronize data between the desktop and mobile environments Although the app will be written in Kotlin and run on Android the fundamental concepts apply to iOS We re choosing Kotlin for the same reasons the Android platform recommends it it s faster to write in offers more code safety than Java and boosts productivity with its expressiveness PrerequisitesBefore we begin install the following software on your machine Salesforce CLI ーthis is a CLI designed by Salesforce to simplify platform interactions Kotlin gt A recent version of Node gt All Android specific requirements listed hereGitSince we re just exploring the SDK right now it s important that whatever we build doesn t affect your “real production Salesforce organization also called org for short Therefore we re going to create a separate free Developer Edition org which our app can interact with First sign up for your Developer Edition Take note of your username as you ll need it in a moment After you ve verified your email address and your org is available for use go ahead and follow these instructions to clone the dreamhouse lwc project onto your computer and then upload it to your new org using sfdx the Salesforce CLI The Dreamhouse app is a sample Salesforce application that lists realtors and their associated properties After following the instructions linked above the app will contain sample data which we can interact with To see the app enter the following command to open up your org sfdx force org open u lt username or alias gt Note When you authorized your org with the command line you were instructed to create an alias This is interchangeable with username to pass into the u parameter above This opens a browser window and takes you to your Salesforce org Click on the App Launcher icon the grid of dots in the upper left corner and select the Dreamhouse app As you explore it you should see information on properties brokers and more This app and its corresponding custom objects represent the platform our mobile app will interact with Setting up the Android Studio IDEWe will use the Android Studio IDE for this Kotlin app This page lists everything you need to do to prepare your computer for Android development Understanding this documentation is essential for building your Android app but here s a brief overview of what you need to do First install forcedroid an npm package that assists you with Salesforce mobile app development by running the following in the terminal npm install g forcedroidNext run forcedroid create and provide the following values The application type is native kotlinThe application name is sfdc mobile appThe package name is com example sfdcThe organization name is DreamhouseSet the output directory to the current directoryOpen Android Studio and navigate to the directory where you created this app Create an Android Virtual Deviceーan emulatorーand download the API version R system image onto it To ensure that everything is set up properly click the Run button which is the green triangle at the top bar A phone emulator should pop up and boot with Android You ll be greeted with a Salesforce login screen Let s test that we can communicate with our Developer Edition org In the top right corner of the form click the menu icon then select Change Server After that click Add New Connection Earlier when we called sfdx force org open in the command line a URL was displayed Copy the entire domain that was displayed using that as your custom domain For example it might look something like this flow app dev ed cs my salesforce com Paste that in as the value of your new connection After that return to the login screen and log in with your username and password Your username and password are the same as those you use to log into your Developer Edition org Once you ve authenticated successfully you ll be ready to write the app Displaying DataSince our Dreamhouse app already contains custom objects our first step will be to display some of that same data in the mobile app To do that we ll authenticate the Salesforce mobile app to Salesforce com and then fetch a list of brokers Let s take a brief look at what forcedroid did for us Inside the app java com example sfdc folder it created two files MainActivity kt and MainApplication kt You can read up on the specifics of these files However in a nutshell MainApplication sets up the Salesforce Mobile SDK MainActivity is the app s “home page and is responsible for all other UI navigation and functionality You may have noticed the option to click on some buttons and fetch data when you launched the app While it s nice that the Mobile SDK sets up an environment where you can get up and running that s no fun if weーintrepid developers that we areーwant to build something from scratch Let s make a few changes to the files we ve been given to start exploring the SDK Let s start with the view first Open up app res layout main xml then switch to the Code view Paste in the following XML layout lt xml version encoding utf gt lt LinearLayout xmlns android android orientation vertical android layout width match parent android layout height match parent android background android colorBackground android id id root gt lt include layout layout header gt lt ListView android id id brokers list android layout width match parent android layout height match parent android background android colorBackground android textColor android textColor gt lt LinearLayout gt Here we ve set up a simple list with the id brokers list which will act as the container for our brokers To make accessing these views easier in code we re going to set up a feature called View Binding In the left pane expand the Gradle scripts category and select the build gradle file for your module Within the Android namespace add these lines to enable View Binding buildFeatures viewBinding true Now in MainActivity kt we need to make two changes We need to associate the layout ID with a variable we can use in Kotlin and we need to make a request to display a list of brokers First we need to import our layouts add these to the top of the file near the other import statements import com example sfdc databinding MainBindingThen initialize a view variable within the MainActivity class class MainActivity SalesforceActivity … private lateinit var mainViewBinding MainBinding …In the onCreate function change the final line which reads setContentView R layout main to these lines mainViewBinding MainBinding inflate layoutInflater val view mainViewBinding root Setup viewsetContentView view This has now set a value for our mainViewBinding variable We can now populate our layouts with logic defined in our code Replace the existing onResume functions with these lines override fun onResume Hide everything until we are logged in mainViewBinding root visibility View INVISIBLE Create list adapter listAdapter ArrayAdapter this android R layout simple list item ArrayList lt String gt mainViewBinding brokersList adapter listAdapter super onResume override fun onResume client RestClient Keeping reference to rest client this client client Show everything mainViewBinding root visibility View VISIBLE sendRequest SELECT Name FROM Broker c mainViewBinding uses the IDs we defined in the layout while sendRequest makes a query to Salesforce to fetch the records for you Go ahead and launch the app you will receive a list of these broker namesーfront and center Notice what we haven t done here We didn t write any code to do the Salesforce authentication and our business logic to fetch records was already abstracted away for us by the Mobile SDK All we had to do was design the layout and create a new query that matched what we wanted to get out of the database To Be Continued This is a great stopping point to reflect on what we ve done We set up a new Developer Edition org and pushed a sample app with sample data called Dreamhouse We set up an Android emulator and the Salesforce Mobile SDKWe built an app logged into our org and fetched data from itIn the Part Two of this series we ll learn how to edit and insert data from the app to our org Stay tuned	2022-02-23 19:53:44

海外TECH	DEV Community	100. Same Tree	https://dev.to/melguachun/100-same-tree-447c	Same TreeI m excited to cover this Leetcode algorithm for many reasons For the first time despite how minuscule it might seem I was able to write out the steps solve this problem This is a huge accomplishment for many reasons There is often a disconnect in learning between seeing and doing Especially when learning on your own it s hard to strike a balance between watching others and tackling something on your own Studying algorithms makes this just a challenging So to be able to break down my thought process into coding steps to achieve a solution shows that I am witnessing a bridge between seeing and doing I m starting to find connections between my thought process and transferring it into code So lets dive into it Given the roots of two binary trees p and q write a function to check if they are the same or not Two binary trees are considered the same if they are structurally identical and the nodes have the same value If we look at the first example we can further understand what makes a tree structurally identical to another What makes a binary tree identical are the following root nodes have the same valueleft subtree is identical right subtree is identicalThis means that both trees must have the same number of nodes as well as the same value at every node s position In this case the left subtree has a value of two in both trees and the right subtree has a value of three in both trees In example one we can see that trees p and q fulfill all the requirements to make them structurally identical Now that we understand what makes trees structurally identical let s think about how we can solve this algorithm The solution I found will be a recursive solution called Depth First Search DFS Depth First Search is the concept of choosing a node as a starting point and persist to the next neighboring nodes When recurring from the first node to the next the prior node is marked In the wort case all nodes will be visited at some point in this problem therefor time complexity will be O p q where the size of both trees will be added together Before we start coding let s think of some base cases for this solution Lets say If both trees are null that means that they are the same so we would return True if not p and not q return TrueWe are using conditional logic by using and to signify both p tree and q tree must be null to be True If one tree is null and the other has a node then they are not structurally identical which would return False if not p or not q or p val q val return FalseAgain we are using conditional by using or to say it doesn t matter which tree has a node or is null hence we must return False If there is a root check the value of that node If the vale is the same between trees p and q return True Otherwise return False return self isSameTree p left q left and self isSameTree p right q right Now let s compile this all together to get our solution class Solution def isSameTree self p Optional TreeNode q Optional TreeNode gt bool if not p and not q return True if not p or not q or p val q val return False return self isSameTree p left q left and self isSameTree p right q right In the first if statement we are implementing a base case to check if the trees are null If both are null it means they are structural identical and we return True In the second if statement we are checking our second base case that determines if one tree is null and the other has a node then the values of trees p and q are not equal so we return False If the two trees are not null and they have the same structure it will be passed to the last two lines of our code The last two lines will determine if there is a root to check the values of the root and then continue throughout the subtrees to compare their values If they are the same in value and structure it will return True otherwise it will be False Conclusion This is a note to all beginner coders programmers engineers and developers keep going I haven t been practicing algorithms for very long and I m still constantly bombarded with doubt throughout this process But having that moment of enlightenment where you can look at an algorithm and be a little less intimidated is an accomplishment within itself There is so much to learn out there which makes it hard to be patient but try not to let that stop you When it comes to algorithms try your best If you get stuck google it that s part of our job Try to understand how you got to your answer and the code behind it and move on Progress isn t a straight incline You will be where you want to be in due time Resources	2022-02-23 19:31:04
海外TECH	DEV Community	Intro to React - JSX and Elements	https://dev.to/maxdemaio/intro-to-react-jsx-and-elements-3n8k	Intro to React JSX and ElementsReact is a modern JavaScript library for building interactive user interfaces In this blog post we ll get a brief introduction and how to get started with React Demos Create React App demo Why React Let s look at an Instagram post I ve made The moment I “like a post the status changes The heart becomes red the number of likes changes and we can immediately see this on the web page Instagram has to do the changes by updating the DOM tree of the page and re rendering the page in the browser The application also has to show other Instagrammers that I ve liked this post if they re looking at it too As of it was recorded that Instagram had over billion users Revista Economică As of the date of this blog post that number has probably soared to over billion users Considering the size of Instagram it d be a challenge to ensure efficient and consistent DOM manipulation Luckily Facebook had already created a frontend library called React specialized in this What is React To make it short and snappy React js is a JavaScript library It allows developers to create user interfaces UIs and make the development of UI components easy and modular It was created by Jordan Walke a software developer at Facebook and it was open sourced to the world by Facebook and Instagram React FeaturesComponents JSX components are the building blocks of React applications Think of HTML templates but we write them using a special syntax called JSX After compilation JSX expressions become JavaScript function calls and evaluate to JavaScript objects Components can be simple or stateful Simple component that will display Yo props name class YoMessage extends React Component render return lt div gt Yo this props name lt div gt ReactDOM render lt YoMessage name MaxMayo gt document getElementById yo example Classic timer stateful componentclass Timer extends React Component constructor props super props this state seconds tick this setState state gt seconds state seconds componentDidMount this interval setInterval gt this tick Virtual DOM Instead of rebuilding the entire DOM tree for updates React makes use of the virtual DOM The virtual DOM is a lightweight copy of the actual DOM React will update exactly which virtual DOM objects have changed through diffing Unidirectional Data Flow React has a waterfall like concept of transferring data to other parts of the application State is passed to the view and child components Actions are triggered by the view and can update state SEO Performance you can even run React on the server for SEO performance code sharing and flexibility Getting StartedWe can use create react app to bootstrap a React application The only prerequisite is that we need Node js version We can check the Node version in our system with the command node v Off to the races npx create react app my appcd my appnpm startHere s a quick explanation of the folder structure generated by create react app FilesPurposenode modules All app dependencies live in this folderpublic This folder contains the public static assets of the applicationpublic index htmlThis is the first page that gets loaded when we run the applicationsrc All application related files folders are created in this foldersrc index jsThe entry point of the applicationpackage jsonContains the dependencies of the React applicationIf we observe the index js file we can see the following ReactDOM render lt React StrictMode gt lt App gt lt React StrictMode gt document getElementById root ReactDOM render renders an element or component to the virtual DOM The first parameter specifies what needs to be rendered The second argument specifies where to render A smaller example without components would look like this ReactDOM render lt h gt Yo world lt h gt document getElementById root Babel compiles JSX down to React createElement calls So these examples are identical const myElement lt h className yo gt Yo world lt h gt const myElement React createElement h className yo Yo world Unlike browser DOM elements React elements are cheap to create because they re plain JavaScript objects Our React render would render these React elements since Babel compiles JSX down to React createElement calls Then React createElement creates objects aka React elements that generally look like this Simplified structureconst myElement type h props className yo children Yo world These React elements are representations of what we d want to see on the screen Note elements make up components React reads these objects and uses them to make the DOM and update it ConclusionIn this blog post we learned about what React is and how to start a React application In future blog posts I ll dive into the main concepts of React with helpful demos Stay tuned Works CitedFUCIU Mircea “The Rise Of Instagram Evolution Statistics Advantages And
