![]() The most significant benefit of adding a version property to a JPA entity is that we can prevent the lost update anomaly, therefore ensuring that data integrity is not compromised. In this article, I’m going to show you how the JPA entity property works when using Hibernate. ![]() So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night! Well, Hypersistence Optimizer is that tool!Īnd it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework. AdonisJS - A fully featured web framework with Node.jsĪnd many, many more great projects.Follow having a tool that can automatically detect JPA and Hibernate performance issues.RxJS - widely used library for reactive programming.Prisma - next-generation ORM featuring a declarative data model, generated migrations and fully type-safe database queries.TypeORM - great ORM influenced by other well-known tools from other languages like Hibernate, Doctrine or Entity Framework.NestJS - robust and fully-featured framework that makes creating scalable and well-architected systems easy and pleasant.Some of the notable examples of open-source projects using TypeScript are: TypeScript is well-established in the Node.js world and used by many companies, open-source projects, tools and frameworks. Some of the other benefits of TypeScript that are worth mentioning are that it can be adopted progressively, it helps making code more readable and understandable and it allows developers to use modern language features while shipping code for older Node.js versions. You can read more about all this awesome stuff in the official TypeScript docs. ![]() Also, on bigger projects you can declare your TypeScript compiler configuration in a separate file and granularly adjust how it works, how strict it is and where it stores compiled files for example. TypeScript offers a whole lot of other great mechanisms like interfaces, classes, utility types and so on. Now how do we run it?įirst thing to do is to install TypeScript in our project:Īs you can see TypeScript successfully prevents us from shipping code that could work unexpectedly. For example, variable isJustineAnAdult would be of type boolean even if we didn't type it explicitly or justine would be valid argument for our function even if we didn't declare this variable as of User type. Secondly, not everything must be typed explicitly - TypeScript is very smart and can deduce types for us. Firstly, if we would not comply with declared types, TypeScript would alarm us that something is wrong and prevent misuse. There are additional things about this example that you should know. ![]() Finally, we create a new variable with information on whether justine is an adult. After this, we create justine, our example data that can be used for calling the previously defined function. Later we utilize this newly created type to create function isAdult that accepts one argument of type User and returns boolean. The first part (with the type keyword) is responsible for declaring our custom object type representing users. Take a look at this code snippet and then we can unpack it together: We can talk about other TypeScript benefits later, let's see some examples now! Examples It makes our code more secure and robust by preventing many bugs before the code is even shipped - it catches problems during code development and integrates wonderfully with code editors like Visual Studio Code. TypeScript is a really powerful tool and opens a new world of possibilities in JavaScript projects. Thanks to types, it's possible, for example, to declare what kind of arguments we are expecting and what is returned exactly in our functions or what's the exact shape of the object that we are creating. The most notable addition is static type definitions, something that is not present in plain JavaScript. It's loved and used by a lot of software developers around the world.īasically, it's a superset of JavaScript that adds new capabilities to the language. TypeScript is a trendy open-source language maintained and developed by Microsoft.
