https://dev.to/code2rithik/how-to-host-your-react-js-application-to-firebase-2foa

How to Host Your React JS Application to FirebasePreviously I wrote a blog about my portfolio If you haven t checked it out yet check it out here My New React Portfolio is out Rithik Samanthula・Apr ・ min read react portfolio webdev In the ending of the post I mentioned that I deployed my React Application to Firebase Want to know how to do this as well Well today I am going to be showing you the same Getting StartedIn this tutorial I will be demonstrating how you can deploy your React app using Firebase Hosting I will assume that you already have a Firebase project set up If you do not you can create one using the Firebase Console You will also need to ensure have a React app created For this I will use Create React App You can create a new React app by running the following npx create react app firebase hosting demo Installing the Firebase CLI ToolsYou will need the Firebase CLI Tools in order to deploy your app to the internet You can do this by using the command npm install firebase tools g Don t forget to add the g flag or else it will not be enabled globally and will set the scope to only this project Login to FirebaseLogin to Firebase console by using firebase loginThen proceed with your google account to login to the Firebase console Initialize FirebaseThe next step is to Initialize Firebase with your project using firebase initYou will then be prompted with a series of questions and configuration options that I will walk through with you Select Hosting Configure and deploy Firebase Hosting sites Then create a project on the Firebase ConsoleThen back in the CLI Select Use an existing projectThen select your firebase project that you created You will now need to specify the folder where Firebase will look for assets to deploy By default Create React App will generate a build folder that will contain the production assets Unless you changed the default configuration you ll want to enter build for this option You will also be asked whether or not Firebase should configure as a single page app You ll want to enter y Yes for this option The last option is whether or not Firebase should overwrite your existing build index html If you haven t created a build for your app yet then you won t see this option You ll want to enter N No for this option though Auto Generated Configuration filesAfter you have completed the initialization you should see new files firebaserc firebase json These files are automatically generated and you will want to save these files and commit them in your git repo as they live in your firebase hosting config You can ignore the firebase directory for now The firebaserc should look similar to the following projects default firebase hosting demo The firebase json should look similar to this hosting public build ignore firebase json node modules rewrites source destination index html Deploying your AppNow that everything is set up you can go ahead and deploy your app All you need to do now is run firebase deployFirebase will then give you a unique URL where your deployed app is located For example it might look similar to orAnd thats pretty much it Thank You for reading my blog and remember Keep Coding Y All |

Connecting the dots: Front-end and Algorithms |
https://dev.to/papercoding22/connecting-the-dots-front-end-and-algorithms-2jpc
|
Connecting the dots Front end and AlgorithmsLast week I had an interview there s an algorithm test which I met it again next week when I was working in the current React project Instantly I recognized it and solved it like eat a cake This just reminds me one of my favorite quotes The algorithm dot Merge IntervalsYou can see details here in LeetCode Example Input intervals Output Explanation Since intervals and overlaps merge them into Example Input intervals Output Explanation Intervals and are considered overlapping A picture says a thousand words Connecting to Front endSo how this algorithm test I took last week related to my current work Let s see a gif belowA gif says a million words Try it yourself ⇒codesandboxThere s a list transactions grouped by date At first load we only load a few items When users press Load More button we call a api to get more data Data come but in section date without merge we see two separate sections Now my mission is to merge theme together Let s go Connecting The DotsThis is the solutionconst merge currentList newList gt We take the currentList at first load and the load more list First we just merge it by spread operator gt currentList newList After that we use Array prototype reduce to generate a new array Which is merged and grouped by date const merged currentList newList reduce acc item gt Condition just push the item to the new empty array or if the last item in acc doesn t have the same date with the current item if acc length acc acc length date item date acc push item else Condition if they have the same date we merge it const lastItem acc acc length const mergedDate lastItem transactions item transactions lastItem transactions mergedDate return acc return merged const result await fakeAPIRequest page setMergedList prevList gt merge cloneDeep prevList cloneDeep result items So this is a little bit different from the algorithm test but the idea is the same Now you can come back to Leetcode and let s solve it by yourself Algorithm test is nightmare sometimes and we often underestimate because in real life project we barely think or use it This experience makes me think differently and inspires me to practice more in next weekends |
