I've completed my Java and Spring Boot training journey, from Alura. Throughout the project developed during the training, I delved into a plethora of technologies: - I created a REST API using Spring Boot and also developed a CRUD. - I learned what Spring Boot is and what its main differences are compared to traditional Spring. I used Spring Initializr to build my project. - I understood how the directory structure works and the "pom.xml" file. I learned to use some of its modules, such as Web, Validation, and Spring Data JPA. - I used other libraries, such as the MySQL driver, Flyway, and Lombok. I also learned how configurations work in a Spring Boot project. - I learned how to perform migrations to control the database's evolution history and how to implement the REST API from creating the controllers. I also learned to use repositories to simplify database access and JPA. - I mapped JPA entities and implemented CRUD with validations. - Standardization of API method returns using ResponseEntity, applying HTTP protocol best practices. - Error handling whenever an exception occurs within any controller class. - Add Spring Security to the project, implementing the concept of authentication and authorization through JWT (JSON Web Token) tokens. - Understanding of security configurations for Spring Security. - Configured Spring Security to not follow the standard authentication and authorization process. - Performed authentication with stateless configuration. - Configured password hashing using the BCrypt algorithm. - Applied filters to intercept requests, verify if the JWT token is included, and log the user. - Implemented Unit Tests - Implemented personalized queries to get data from the database - Applied Strategy Design Pattern - Documented the REST API with Spring Doc - Build the Maven Project

People often say that Node.js is fast. It seems to be, but in the test I conducted, it proved to be the opposite compared to other technologies. In the world of software development, we often see heated debates about which programming language offers the best performance. Recently, I decided to conduct a practical simple test to compare the performance of Ruby, Python, and Node.js when querying 50,000 rows in an Oracle 19c database. ➡️ The Test The goal was simple: measure the time each language takes to execute the same database query. Here are the results: ✅ Python: On the first attempt, it took 22 seconds. On subsequent tries, the times were 16s, 17s, and 20s. Interestingly, there was an improvement in performance over the tests. ✅ Ruby: Maintained a consistent performance, ranging between 24-25 seconds. ✅ Node.js: Surprisingly, it had the worst performance among the three languages tested, between 26-32 seconds. Analysis of the Results These results show that the choice of programming language can significantly influence the performance of your applications. However, it's important to note that the purpose of this post is not to declare a winner but to provoke a reflection on choosing the most suitable technology for each specific case. 💡 Reflection The purpose of this post is not to compete over programming languages or any specific technology, but to encourage you to think outside the box and use the best technology according to the client's requirements. A programming language or any tecnology is not something to be protected like a child, but rather a tool to achieve results. Choose wisely. What criteria do you consider most important when choosing a technology stack for your projects? In general, which programming language do best for automation, data analyses and data cleaning? #Technology #Programming #SoftwareDevelopment #Performance #Python #Ruby #Nodejs #Innovation #DigitalMarketing #Future #Careers #Entrepreneurship #BestAdvice #Business #Leadership #ArtificialIntelligence #Engineering

🚀 Node.js 22.1.0 is here! 🎉 This latest release brings an exciting feature: automatic on-disk code caching. Thanks to the efforts of the Node.js community, Node.js now supports speeding up compilation using on-disk V8 code cache. Simply set the environment variable NODE_COMPILE_CACHE=/path/to/cache/dir to enable it. Find out more about this and other enhancements in the release notes at the link below . Happy coding! #NodeJS #ReleaseUpdate #JS #v8 https://lnkd.in/eVPPUpEp

I had an exciting opportunity to present the advantages of adding #Kotlin to #Java projects to Kotlin Devs Brasil remotely. I also included a short live coding example of how to add Kotlin code to an existing #Java #SpringBoot application. Here is the recording:

I sometimes use the Brazilian framework, Nullstack, for certain projects. Nullstack is particularly useful because it integrates backend and frontend development into a single cohesive process. This eliminates the need to separately create APIs and frontend interfaces. With Nullstack, "server functions" are designated for server-side operations, automatically generating routes (endpoints) and managing these endpoints in the background. However, opinions vary on its approach to integrating SQL and HTML in the same file; this often comes down to personal preference.

I’ve recently embarked on a journey to deepen my knowledge of NestJS, a powerful Node.js framework, and I’m thrilled to share a milestone with you all! 🚀 Achievement: Successfully implemented file uploading through a POST API and seamlessly integrated it with AWS Lambda! and triggered the lambda to run a microservice 🎉 Throughout this process, I’ve gained hands-on experience in: =>Building robust APIs with NestJS =>Managing file uploads =>Utilizing AWS Lambda for serverless functions One of the most impressive aspects of NestJS is its predefined structured approach, which significantly eases the development process. It provides a well-organized architecture that allows for scalability and maintainability, making it a joy to work with. I’m looking forward to exploring more advanced features and best practices with NestJS and AWS. If anyone has tips, resources, or experiences to share, I’m all ears! Let's connect and learn together.

As you might know, in Nearform we really value technologies like Node.js and today I want to talk you about a really interesting book on this topic! Inside of "Mastering Node.js Web Development" by Adam Freeman you will find more +700 pages of useful content! Who is this book for? I think this book might be pretty useful especially for people that have already a background in web development, but are coming from other tech stacks (Java, PHP etc). This can also be super useful if you are a new grad and you will start working with node soon for an internship of your first job. In the first part of the book, you will learn about the JS ecosystem and all the tools necessary to work with Node.js. Then you will learn the basics of JS and TS (yes, no prior Javascript knowledge required!). Then you will learn Node.js itself and how to use it for multiple purposes. The last part (most probably the one I prefer) is a big (almost production-ready) project that you will build with a webserver, authorization and a bunch of useful features (no spoiler!). Based on what I read so far, if you really need to learn Node.js fast and you have no prior knowledge of either the language or Node itself, this book can allow you to learn 90% of what you need in a matter of weeks! Thanks a lot to Priyadarshini and Packt for the review copy! I'm really appreciating the book so far :D

Hi everyone! Today, I discovered some interesting capabilities with Node.js. With just a few lines of code, you can create a template that, when run in the terminal with a given name, generates a folder containing three connected files: index.html, app.css, and app.js. This streamlined approach simplifies the process of setting up your project structure, making it faster and more efficient. Feel free to reach out if you'd like to learn more about how I did this or if you have any Node.js tips to share! #NodeJS #WebDevelopment #Coding #TechInnovation #Programming
