Full Video Link https://youtu.be/CRtVz_kw9qA Hello friends, new #video on #backendforfrontend #bff #designpattern for #microservices #tutorial for #api #developer #programmers with #examples are published on #codeonedigest #youtube channel

In this video we will learn about Backend for Frontend design pattern for microservices.   Backends for Frontends (BFF) is a microservice design pattern to handle the complexity of client-server communication where we have multiple user interfaces. This pattern suggests having a separate back-end service for each frontend to handle the specific needs of that interface. This pattern allows…

how do I set up vsc correctly? I always get project file not found error and I can't find a solution on the internet. Lmk if you have a fix :(

Hi! Thank you for the ask! I wonder in what situation this happens to you? When trying to open the file? Or when trying to run some command? Could be different reasons so maybe my answer won't really help you... But! I've had this issue sometimes; for example, once, I was trying to run a python script, but it wouldn't let me.

Here, the issue is that the folder I have open in VS code is a parent folder to the folder where the file I'm trying to run is located. Here, I'm running the script with the help of the "play" button on the top right.

What it does, I suppose, is try to run the file day-3.py in the directory/folder that is currently open in VS code, but! In the folder advent_of_code_23, there is no file called day-3.py!

So, your issue could potentially be that you are accidentally running your script in a parent folder where it can't be located, since it's in a child folder.

If you still want to have a parent folder up and running, and see all your children folders, you could use the terminal to manually access and run your script.

Step 1: open a new terminal (top option)

Step 2: in the terminal, type ls (stands for list) to see all the folders in your parent folder

Step 3: type cd (stands for change directory) and then the name of the folder you want to navigate into, where the file you want to run is located. (TIP! You can use the tab button on your keyboard to autofill the folder name)

Step 4: Now you can see that your location has changed to be <C:\...\parent-folder-name\child-folder-name>, which means you are now in another folder! So for me, now the location is <C:\...\advent_of_code_23\day-3>, which means I can now directly access everything in this folder! In my screenshot I also typed LS to see what the contents of my folder is.

Step 5: In here, I can now run my python file by typing python day-3.py

If you're working in another language, I would recommend googling "how to start a [language name] in the terminal". Or, if you're running for example a React project, you may want to look in your package.json to see what scripts are available, and run those with your preferred package manager, such as yarn or npm.

In my case, this project is set up with yarn, so I would run this using the yarn dev command.

I hope this has been somewhat helpful, and if it didn't resolve your issue feel free to reach out to me personally and I'd be happy to take a look at your specific case. I can't promise a definite fix, but I can promise that I'll try! 🩷

¿React o Django? Diferencias, Ventajas y Desventajas en el Desarrollo Web / React or Django? Differences, Advantages, and Disadvantages in Web Development

Introducción / Introduction

Español: En el desarrollo web moderno, elegir la tecnología adecuada puede marcar una gran diferencia en el éxito de un proyecto. React y Django son dos de las herramientas más populares, cada una con sus propios puntos fuertes y limitaciones. React, una biblioteca de JavaScript, es ampliamente utilizada para construir interfaces de usuario dinámicas y altamente interactivas. Django, por otro lado, es un framework de Python que permite crear aplicaciones web robustas y seguras con rapidez. En este blog, exploraremos las diferencias clave entre React y Django, así como sus ventajas y desventajas, para ayudarte a decidir cuál es la mejor opción según tus necesidades.

English: In modern web development, choosing the right technology can make a significant difference in a project's success. React and Django are two of the most popular tools, each with its strengths and limitations. React, a JavaScript library, is widely used for building dynamic and highly interactive user interfaces. Django, on the other hand, is a Python framework that allows for creating robust and secure web applications quickly. In this blog, we will explore the key differences between React and Django, as well as their advantages and disadvantages, to help you decide which one is the best fit for your needs.

1. Diferencias Fundamentales / Fundamental Differences

Español: La principal diferencia entre React y Django es su propósito y enfoque en el desarrollo web:

React: Es una biblioteca de JavaScript utilizada principalmente para construir interfaces de usuario (UI). React se enfoca en la vista en la arquitectura MVC (Modelo-Vista-Controlador), permitiendo la creación de aplicaciones web dinámicas y de una sola página (SPA). React es ideal para manejar la parte frontal de las aplicaciones web, proporcionando herramientas para crear componentes reutilizables y gestionar el estado de la aplicación.

Django: Es un framework completo de Python diseñado para construir aplicaciones web desde cero. Django sigue la arquitectura MVT (Modelo-Vista-Plantilla) y proporciona todo lo necesario para manejar tanto el backend como el frontend de una aplicación web. Es una opción excelente para proyectos que requieren un sistema de autenticación, bases de datos robustas y administración de contenido.

English: The main difference between React and Django is their purpose and focus in web development:

React: It is a JavaScript library primarily used for building user interfaces (UI). React focuses on the view in the MVC (Model-View-Controller) architecture, enabling the creation of dynamic and single-page web applications (SPA). React is ideal for handling the front end of web applications, providing tools to create reusable components and manage application state.

Django: It is a full-stack Python framework designed to build web applications from scratch. Django follows the MVT (Model-View-Template) architecture and provides everything needed to handle both the backend and frontend of a web application. It is an excellent choice for projects requiring an authentication system, robust databases, and content management.

2. Ventajas de React / Advantages of React

Español:

Interactividad y Dinamismo: React permite crear interfaces de usuario altamente interactivas con actualizaciones en tiempo real sin necesidad de recargar la página completa.

Componentes Reutilizables: Los componentes en React son reutilizables, lo que facilita la creación de elementos UI consistentes y la gestión del código.

Amplia Comunidad y Ecosistema: React cuenta con una gran comunidad y un ecosistema de herramientas y librerías que simplifican el desarrollo, como Redux para la gestión del estado y React Router para la navegación.

Rendimiento: React optimiza automáticamente la actualización de la UI mediante el uso de un DOM virtual, lo que mejora el rendimiento de las aplicaciones.

English:

Interactivity and Dynamism: React allows creating highly interactive user interfaces with real-time updates without needing to reload the entire page.

Reusable Components: Components in React are reusable, making it easier to create consistent UI elements and manage code.

Large Community and Ecosystem: React has a large community and an ecosystem of tools and libraries that simplify development, such as Redux for state management and React Router for navigation.

Performance: React automatically optimizes UI updates using a virtual DOM, improving the performance of applications.

3. Desventajas de React / Disadvantages of React

Español:

Curva de Aprendizaje: Aunque React es flexible, su flexibilidad puede ser una desventaja para principiantes que no estén familiarizados con conceptos como JSX, el DOM virtual y la gestión del estado.

Complejidad de Integración: React se centra únicamente en el frontend, por lo que se requiere la integración con otras tecnologías para manejar el backend, lo que puede aumentar la complejidad del proyecto.

Dependencias Externas: Para desarrollar una aplicación completa, es necesario depender de varias librerías y herramientas externas, lo que puede complicar la gestión del proyecto.

English:

Learning Curve: Although React is flexible, its flexibility can be a disadvantage for beginners who are unfamiliar with concepts like JSX, the virtual DOM, and state management.

Integration Complexity: React focuses solely on the frontend, so it requires integration with other technologies to handle the backend, which can increase project complexity.

External Dependencies: Developing a complete application requires relying on various external libraries and tools, which can complicate project management.

4. Ventajas de Django / Advantages of Django

Español:

Framework Completo: Django es un framework completo que incluye todo lo necesario para el desarrollo de aplicaciones web, desde la autenticación de usuarios hasta la gestión de bases de datos.

Seguridad: Django viene con características de seguridad integradas, como protección contra CSRF, SQL injection y XSS, lo que ayuda a crear aplicaciones web seguras por defecto.

Rapidez en el Desarrollo: Con Django, se puede desarrollar aplicaciones de manera rápida gracias a su enfoque en la reutilización de código, el sistema de administración automático y las migraciones de bases de datos.

Soporte para Proyectos Grandes: Django es ideal para proyectos de gran escala, como redes sociales, plataformas de comercio electrónico y sistemas de gestión de contenido, gracias a su robustez y escalabilidad.

English:

Full-Stack Framework: Django is a full-stack framework that includes everything needed for web application development, from user authentication to database management.

Security: Django comes with built-in security features like protection against CSRF, SQL injection, and XSS, helping to create secure web applications by default.

Rapid Development: With Django, applications can be developed quickly thanks to its focus on code reuse, the automatic administration system, and database migrations.

Support for Large Projects: Django is ideal for large-scale projects such as social networks, e-commerce platforms, and content management systems due to its robustness and scalability.

5. Desventajas de Django / Disadvantages of Django

Español:

Rigidez: Django sigue un enfoque de "una forma correcta de hacer las cosas", lo que puede ser restrictivo para desarrolladores que prefieren más flexibilidad en cómo estructurar su código.

Curva de Aprendizaje para Nuevos Usuarios: Aunque Django es poderoso, la curva de aprendizaje puede ser empinada, especialmente para desarrolladores que no están familiarizados con Python o con los patrones de diseño que utiliza.

Menor Interactividad: Comparado con React, las aplicaciones desarrolladas con Django pueden tener menos interactividad en el frontend, a menos que se integren con librerías de JavaScript.

English:

Rigidity: Django follows a "one right way to do things" approach, which can be restrictive for developers who prefer more flexibility in structuring their code.

Learning Curve for New Users: While Django is powerful, the learning curve can be steep, especially for developers who are not familiar with Python or the design patterns it uses.

Less Interactivity: Compared to React, applications developed with Django may have less interactivity on the frontend unless integrated with JavaScript libraries.

6. ¿Cuándo Usar React o Django? / When to Use React or Django?

Español:

Usa React si:

Necesitas construir una interfaz de usuario interactiva y dinámica.

Estás desarrollando una aplicación de una sola página (SPA).

Quieres utilizar una biblioteca con un amplio soporte y comunidad.

Prefieres trabajar con JavaScript y te interesa mantener el frontend separado del backend.

Conclusión / Conclusion

Español: La elección entre React y Django depende en gran medida de las necesidades específicas de tu proyecto. React es ideal para crear interfaces de usuario dinámicas y modernas, mientras que Django proporciona un framework completo para el desarrollo rápido de aplicaciones web robustas. Si tu enfoque es en la interactividad del frontend, React podría ser la mejor opción. Si buscas una solución integral que incluya tanto el backend como el frontend, Django puede ser la elección correcta.

English: The choice between React and Django largely depends on the specific needs of your project. React is ideal for creating dynamic, modern user interfaces, while Django provides a comprehensive framework for rapidly developing robust web applications.
