How to Use an LLM-Powered Boilerplate for Building Your Own Node.js API

Building on this progress, I’ve extended my existing Node.js API boilerplate with a new tool LLM Codegen.
A standalone feature enables the boilerplate to automatically generate module code for any purpose based on text descriptions.
The generated module comes complete with E2E tests, database migrations, seed data, and necessary business logic.
This boilerplate follows specific structures and patterns that I believe are of high quality.
The generated code after the first stage is clean and adheres to vertical slicing architecture principles.
The second use case involves generating DB migration with the appropriate schema and updating the seed script with the necessary data.
The final use case is generating E2E tests, which help confirm that the generated code works correctly.
LLM clients are OpenAI and Claude.
The core remaining work is performed by micro-agents: Developer, Troubleshooter, and TestsFixer.
During the development and testing, it was used with various module descriptions, ranging from simple to highly detailed.

Unlocking Multiprocessing for Smoother Web Applications

Coaction is a state management library designed specifically for multithreading environments in web applications.
Coaction leverages the power of web workers and shared workers to offload computationally intensive tasks and state management logic from the worker thread, delivering a more responsive and fluid user interface.
The library offers many features like multithreading synchronization, immutable state with optional mutability, patch-based updates, built-in computed, slices pattern, extensible middleware, and integration with third-party libraries like React, Angular, Vue, Svelte, and Solid.
Coaction is a performant library, performing hundreds of times faster than other state management libraries in large initialization tasks.
The library operates in two modes: standard mode and shared mode.
Standard mode stores the state entirely on the webpage thread, whereas shared mode utilizes the worker thread as the primary source of shared state, with the webpage thread as a client.
The shared mode of Coaction automatically manages the store's execution context based on the transport parameters, making synchronization seamless.
Coaction supports remote synchronization, making it suitable for building CRDTs application.
Coaction is an intuitive library with a smooth learning curve and a productive development workflow, designed for developers who strive to create exceptional user experiences in a world where parallelism and responsiveness are essential.
Coaction is a valuable tool for building the next generation of web applications without sacrificing performance, developer experience, or architectural integrity.

The Backend Testing Breakup 💔

Testing can be painless and manageable by following simple principles like testing early and only testing once for each functionality.
Levels of testing include Unit tests, Component tests, Contract and Integration tests and Smoke tests.
Unit tests are for the smallest unit of logic and ensure that the logic behaves as expected given different inputs.
Component tests ensure that all functions can be chained together and validates how execution flows through the application.
Contract and Integration tests ensure that external dependencies adhere to the expected contracts and behavior.
Smoke tests help identify major issues that have been missed by previous levels of testing when an application is deployed.
Implementing the strangler pattern for updates helps streamline the migration of test suites.
Getting buy-in from a team and the business can help ease the transition and result in benefits like quicker feedback and more reliable software.

HTTP DELETE With Request Body

HTTP DELETE traditionally does not support request bodies, but some APIs require it. However, we can send a DELETE request with a body by using HttpEntity in Spring RestTemplate.
To send a DELETE request with a body via Spring RestTemplate, create a HttpHeaders object specifying the necessary headers for the request as well as an HttpEntity that contains both the headers and the request body.
Apache HttpClient is another Java library for making HTTP requests. While Apache HttpClient does not natively provide support for HTTP DELETE with a request body, you can define a custom HTTP DELETE method (e.g., HttpDeleteWithBody) and specify its method as DELETE.
Compared to Spring RestTemplate, Apache HttpClient requires more configuration and coding effort to use but provides more control over the HTTP request and response details.
Spring RestTemplate is ideal for simple, quick integrations with RESTful APIs in Spring applications, while Apache HttpClient is ideal for advanced features such as custom authentication or managing connection pooling.
While it is possible to send a DELETE request with a body, it's important to note that not all servers or APIs may accept this type of request. Referring to the API documentation before implementing it in production is critical.
This article outlines how to send HTTP DELETE requests with a body in Java using both Spring RestTemplate and Apache HttpClient.
This article also compares the two libraries in terms of ease of use, flexibility, built-in features, and more to help you choose the best option for your specific use case.
Lastly, the article concludes with a reminder to always review the API documentation before sending a DELETE request with a body.
Spring provides flexibility for sending HTTP requests with custom headers and a body, even for methods like DELETE that do not traditionally support a request body, using RestTemplate.

Next.js vs React - Performance and Architecture Analysis In-Depth Comparison

Choosing between Next.js and React is a crucial architectural decision that impacts your project's performance, scalability, and maintainability.
Next.js introduces several architectural patterns that extend React's capabilities.
React's traditional client-side architecture can be slow and impact TTFB.
Next.js provides better SEO out of the box and reduces build times with pre-rendering.
Next.js provides built-in performance optimizations, while React requires manual optimization strategies.
Choose Next.js for server-side rendering, static site generation, and built-in API routes.
React remains the better choice for highly interactive single-page applications and projects where you need complete control over the rendering process.
Understanding your project's requirements is key to choosing the right framework.
Both frameworks are powerful tools in modern web development.
