How to use Chat GPT in JavaScript optimizations for Node.js
•
0 gefällt mir•28 views
The document discusses using ChatGPT to optimize JavaScript code for Node.js applications. It explores complex tasks related to JavaScript, OOP, patterns and asynchronous programming. The objectives are to determine if AI can replace developers and what affects ChatGPT code quality. Tasks include network protocol streaming, promise chains and cryptographically secure random number generation. The conclusion is that ChatGPT requires detailed prompts, which take significant time and expertise to prepare, and results are equal whether using version 3.5 or 4 with short prompts but better with detailed prompts. Links to code examples are provided.

ITB_2023_Chatgpt_Box_Scott_Steinbeck.pdf
Everyone has been hearing about Machine learning and AI for a while now, but recently, it exploded.
Like you, Ortus and the CFML Community have been playing with AI too, and one of the end results is ChatGPT Box.
AI is cool, and for some people scary, but a lot of people wonder if there is really any true value for us developers, or our businesses. In this session we’ll discuss what ChatGPT Box is, why we created it, what types of problems it solves, why we are using AI to solve those problems, and how we trained and tamed our own AI.
We will also touch on some of the science behind the scenes, to help you understand the moving parts, and how ChatGPT Box v1.0.0 is just a drop in the ocean of the possibilities, we’ll touch on some ideas we have, and in the end, using ChatGPT Box can make you a much more productive Ortusian Developer!
Polar talks: code generation
3rd Polar Talks session:
How code generation and meta-programming influence developer's activity?
Do we gain more productivity, consistency and simplicity during everyday development for the cost of maintenability and complexity of the generated code?
It was an open public discussion involving colleague experts from other companies. The goal is to tackle the opinions on a certain topics from IT.
Why Go Lang?
Go is used for many popular projects like Kubernetes, Docker, Prometheus, and Ethereum due to its advantages like being statically compiled, allowing for easy distribution and parallelism. Google migrated its dl.google.com download service from C++ to Go because the Go version was much less code, more readable, testable, and fixed HTTP issues while having equal or better performance. Go's creators aimed to design a language that is simple yet powerful for building reliable and efficient software in the modern era.
Riereta Node.js session 3 (with notes)
Node.js is a server-side JavaScript platform for easily building fast, scalable network applications. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, especially for real-time web applications with long-running operations. Node.js applications are written in JavaScript and can be run within the Node.js runtime on different platforms. Common uses of Node.js include web development, real-time applications, IoT, and scripting or build tasks.
How to get started with Site Reliability Engineering
Many companies are looking for "DevOps'' in many forms, but what kind of skills or experiences are actually needed? I’ll debunk some of the myths surrounding what recruiters or internet lurkers might tell you and find out if you might actually have an aptitude for Site Reliability or Infrastructure Engineering. If so, what might be good knowledge areas to get started with? And if learning leads to an interview, what might that look like?
On component interface
The document discusses component interface design. It defines an interface and contrasts an API approach with a protocol approach. It provides examples of common bad interface practices like deceptive APIs and DSLs as APIs. It also discusses issues with distributed systems like idempotency keys and the coupling spectrum. The document emphasizes designing error messages for the caller and distinguishing component purpose from implementation.
What is the best programming language for your web product?
This document discusses considerations for choosing the best programming language for a web product based on different use cases and business needs. It outlines several common cases such as classic CRUD web portals, real-time applications, machine learning, and blockchain and recommends languages like PHP, Ruby, Node.js, Python, Go, and Elixir based on the technical requirements. The key takeaway is that there is no single best language and business goals should dictate the tools based on factors like human resources, ecosystem, and scalability.

Node.js for enterprise - JS Conference
This document discusses using Node.js for enterprise applications. It recommends a layered architecture approach with the domain model at the center. It also discusses applying design principles like SOLID and patterns like GRASP to Node.js projects for reliability, maintainability and other enterprise requirements. Schema-driven development is presented as an approach to generate artifacts like database schemas and type definitions from domain schemas.
Node.js in 2021
Node.js in 2021 discusses new features in Node.js 14.x and 15.x like multithreading and QUIC support. It also covers challenges for the next decade such as meeting enterprise requirements around reliability and security. Key points of engineering culture with Node.js include recommending layered architectures, solid principles and design patterns, and techniques for handling errors and asynchronous programming. The document provides an example of an onion architecture and new strategies for Node.js applications.
Node.js middleware: Never again!
Video: https://youtu.be/RS8x73z4csI
What is middleware?
Mixins, Reference pollution and shared state, Race condition and Abstraction leaks, Fat controller and layers mix, High coupling and Error ignoring
Patterns and antipatterns
1. The document discusses various techniques for limiting concurrency in Node.js applications to avoid resource starvation, including using a counter variable, asynchronous queue, counting semaphore, or external load balancer with monitoring.
2. Examples are given of using an asynchronous queue and counting semaphore to limit concurrency, with references provided to open source implementations.
3. The V8 serialization API is described as a way to serialize JavaScript objects to pass between contexts, with examples of serializing and deserializing an array.
Race-conditions-web-locks-and-shared-memory
The document discusses parallel programming in Node.js using worker threads, SharedArrayBuffer, and Atomics. It provides an overview of the worker threads API and MessagePort for communication between threads. It describes how to wrap shared memory with classes for object-oriented programming. SharedArrayBuffer can be used with typed array views like Int8Array to access memory in a multithreaded context.
Asynchronous programming and mutlithreading
This document discusses asynchronous programming in Node.js. It covers callbacks, promises, async/await and other approaches. Some key points made include:
- Callbacks can lead to "callback hell" with deeply nested code. Separating functions and following error-first conventions can help.
- Promises separate control flow for success and failure cases compared to callbacks. Complex parallel/sequential code can still be difficult.
- Async/await makes asynchronous code look synchronous but still uses promises under the hood. It can also lead to nested code issues.
- Other approaches discussed include EventEmitters, generators/yield, observables and asynchronous composition utilities. The document compares strengths and limitations of different approaches.
Node.js in 2020 - part 3
Мы закончим обзор новых возможностей Node.js и сложив все это вместе в Node.js Starter Kit (шаблона проекта) от сообщества Metarhia для построения надежных и масштабируемых облачных и кластерных приложений и быстрой разработки API для высоконагруженных и интерактивных систем. Будет опубликован манифест Metaserverless. Мы разберем код, обсудим использование новейших возможностей платформы Node.js и фундаментальных знаний CS для построения грамотной структуры и архитектуры проекта.
Node.js in 2020 - part 2
The document discusses software design patterns and principles including:
1. GRASP (General Responsibility Assignment Software Patterns) which deals with assigning responsibilities and coupling/cohesion.
2. SOLID principles for object-oriented design including single responsibility, open/closed, Liskov substitution etc.
3. Design patterns from the Gang of Four (GoF) book including creational, structural and behavioral patterns.
It provides examples of how these concepts relate to JavaScript and Node.js application architecture by discussing concerns like layers, abstraction and separation of concerns.

Node.js in 2020 - part 1
Fwdays вединар: Node.js in 2020: Выйди и зайди нормально - Часть 1
Видео: https://youtu.be/GJY2dyE6328?t=480
За последние 5 лет Node.js очень изменился, но знания о платформе у сообщества остались на уровне 2013-2015 годов, все те же подходы, все те же проблемы. Сообщество плохо следит за новыми возможности, а если и узнает про них, то это не влияет на написание ежедневного кода. В Node.js, да и в JavaScript, слабо проникают фундаментальные знания по программной инженерии и архитектуре, параллельному программированию, GRASP, SOLID, GoF, а если и проникают, то не подвергаются адаптации и переосмыслению. Поэтому, среди других языков программирования JavaScript воспринимается, как несерьезный, а Node.js, как платформа для малограмотных людей. Как преодолеть эту тенденцию и как изменить подход к разработке на Node.js в 2020 году, с использованием всех современных возможностей и знаний, а так же, что нужно изменить в ежедневных практиках написания кода, эти и другие вопросы будут освещены в докладе «Node.js в 2020: Выйди и зайди нормально».

Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

Odoo ERP Vs. Traditional ERP Systems – A Comparative Analysis
When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

How to use Chat GPT in JavaScript optimizations for Node.js
- 1. How to use Chat GPT in JavaScript optimizations for Node.js Timur Shemsedinov github.com/tshemsedinov Chief Software Architect at Metarhia, CTO at Salucyber Lecturer at Kiev Polytechnic Institute & Kiev School of Economics
- 2. Research approach ● Complex tasks: requires deep understanding of JavaScript, Node.js, OOP, patterns, async, etc. ● Not common tasks: solutions can't be found easily in the web ● Interesting and useful tasks: can be put into practice
- 3. Research objectives Find answers: ● Сan AI replace the developer (now, near future) ? ● What affects chat gpt code quality? Learn how to... ● Prepare prompt for chat GPT ● Build a dialogue to get the desired result faster
- 4. Tasks ● Network protocol (over websocket) streaming chunk encode/decode with typed arrays ● Promise chain and async I/O code optimization for reading app configuration with defaults ● Buffer prefetcher for generation cryptographically strong pseudorandom numbers
- 5. Conclusions ● As of now Chat GPT requires detailed prompt ● Preparing such a prompt takes a lot of time and requires high knowledge comparable to the manual optimization ● Version 3.5 and 4 gives almost equal bad result with short prompt and almost equal good result with detailed prompt
- 6. Links ● Chunk encode/decode with typed arrays: https://github.com/HowProgrammingWorks/ChatGPT/tree/main/JavaScript/1-Chunk ● Promise chain and async code optimization: https://github.com/HowProgrammingWorks/ChatGPT/tree/main/JavaScript/2-Promise ● Crypto random prefetcher: https://github.com/HowProgrammingWorks/ChatGPT/tree/main/JavaScript/3-Prefetcher
