Introduction to Database Transaction |

Introduction to Database Transaction Database TransactionDatabase transaction is a collection of multiple database operations ex SELECT UPDATE DELETE or INSERT as a single unit of work It represent real world events of any company Error handling becomes much simple for an application when using transactions We can define where the transaction will begin and when the transaction will end To start the transaction we use BEGIN syntax If queries in a transaction ran successfully then we save the changes using COMMIT syntax If queries in a transaction failed to run then we revert the changes before the transaction ran using ROLLBACK syntax Now let s see the example of a transaction ExampleAlice wants to transfer to John In the database ACCOUNT table stored Alice and John account data In a transaction the operations are Select Alice account data Check the balanceSELECT BALANCE FROM ACCOUNT WHERE ID Substract from Alice balanceUPDATE ACCOUNT SET BALANCE BALANCE WHERE ID Add to Alice balanceUPDATE ACCOUNT SET BALANCE BALANCE WHERE ID If the operations was success then we have to commit the transaction using COMMITIf one of the operations was failed then we have to rollback the transaction using ROLLBACK SourcesWangde A Deep Dive into Database Concurrency ControlPulkit Gupta System Design Database Transactions amp ACID compliance Part Adam Edelweiss Relational Database Database TransactionHussein Nasser What is a Database transaction |

Medium like Blog Post Builder in React using typescript |
https://dev.to/selvaece25/medium-like-blog-post-builder-in-react-using-typescript-1g78
|
Medium like Blog Post Builder in React using typescriptThis blog post is about will give you complete knowledge about how to start with react Graphql using typescript and the separation of concern and clean architecture folder structure Keep in mind that if you get stuck on any step refer to the Github repoTo find the completed project Demo link This is what we are going to create What is GraphQL Before going forward let me give a very brief overview of GraphQL and what all things we are going to discuss So GraphQL is a query language for APIs that is developed by Facebook It is an efficient alternative to REST because of its features such as With GraphQL there s no over fetching or under fetching of data unlike REST Strongly typed graphQL schema which can be written in GraphQL Schema Definition Language SDL helps you validate your API requests during its compile time With the development of various GraphQL libraries Apollo Relay etc you are getting a lot of features such as caching realtime data etc It provides a large and amazing community You can always get your queries answered whenever stuck This was just a basic introduction to GraphQL but I recommend you to visit the site to gain deeper insights of the same What we ll do I will be mainly focussing on the front end side where I am gonna explain the two very useful react hooks useQuery and useMutation how are we using these in our project for GraphQL operations along with the code Wait what are GraphQL operations GraphQL provides various types of operations such as Query Mutation and Subscription which act as the entry points for the requests sent by the client In this blog I ll be discussing the first two types i e Query and Mutation I m going to use graphql hooks have two operations useQuery useMutation UseQuery Basic syntax const loading error data useQuery lt Type Type gt QUERY STRING variables lt variable gt onCompleted gt console log query successful data onError error gt console error error data The required data we are getting after the query is successful loading It is a boolean value if true it means the query is still in flight After it is successful the value of loading changes to false error It stores the error if occurred while querying useMutation Basic syntax const mutateFunction error loading useMutation lt Type gt MUTATION STRING onCompleted gt console log details updated onError error gt onError error gt console error error refetchQueries query QUERY STRING variables lt variable gt mutateFunction It is the mutate function which can be called anytime to run the mutation The second parameter is the object representing the mutation s execution status such as error loading which have been explained above To use those operation in App need to wrap your app with the provider import GraphQLClient ClientContext from graphql hooks const client new GraphQLClient url graphql function App return lt ClientContext Provider value client gt children lt ClientContext Provider gt Now in your child components you can make use of useQueryimport useQuery from graphql hooks const HOMEPAGE QUERY query HomePage limit Int users limit limit id name function MyComponent const loading error data useQuery HOMEPAGE QUERY variables limit if loading return Loading if error return Something Bad Happened return lt ul gt data users map id name gt lt li key id gt name lt li gt lt ul gt More details and options you can refer link Our project s structure Before we begin let s talk about how our project is going to be organized Once we create our React app using create react app we will have our base React app Once inside that application we will create a component pattern and Our folder structure will look like the following Now let s go over the folders one by one and the and understand the motivation behind them and the type of files you would store in them src Contains all of our react codebase graphql queries This folder contains all static graphql query with props settings pages The name is pretty self explanatory It contains all the Stateful Components as discussed above views This folder contains all the Presentational Stateless Components as discussed above routes This folder contains public private session differentiation and mainly for App navigation start Base react component types Typescript related files or functions utils Helper functions use custom hooks templates I create a different template for React with React Router like global error handling promotions like so on Hopefully you understood how to setup a clean efficient and maintainable folder structure for your React Apps Our goal today is to Create a new React Blogger AppHave Graphqlzero almansi ApiUsing React Routing be able to navigate our app Generate project with CreateReactApp I often to not say always use Create React App to initiate my React projects In order to generate our project run npx create react app my app template typescriptlet s start coding Setting up React Router To get React Router going we are going to need to install our dependency In the project run the following command npm install save react router domIt define the route and call the Auth src start Routes tsxroutesTemplates map routesTemplate gt const routes appRoutes template Template type routesTemplate return appRoutes map appRoute gt return lt Route exact appRoute exact path appRoute path key appRoute path render route gt lt Auth appRoute appRoute Template Template route route type type gt gt Route TypesThere are three route types defined in the project src routes routeTypes tsxexport enum routeTypes private private public public session session private private pages like profile edit profile etc If the user isn t logged then must to show the login page public public pages like about us contact etc session session pages like login and sign up If the user is logged then must to redirect to the private dashboard Routes TemplateIn this file you can define the routes the template and the rights public private session src routes index tsxconst routesTemplate IRouteTemplate routes privateRoutes template GlobalLayout type routeTypes private AuthVerify the rights and redirection src start Auth tsxif isPrivate type amp amp global logged return lt GlobalLayout Component Error route route gt if isSession type amp amp global logged return lt Redirect to gt const Layout appRoute template appRoute template Template return lt Layout Component appRoute component route route gt Building our React componentsIn this application we are going to have fives pages for templates All Posts List with Author DetailsAll Author List with Posts listingPost details Putting it all togetherNow that we have our components set up we can head on over to “localhost and see all pages get render Feel free to ask questions in any area you don t understand To be continued on next article about Graphql implementation |
