Philosophy of the TeqFW Platform

The Philosophy of Tequila Framework (TeqFW) is my personal perspective on web development. I, Alex Gusev, have shaped this approach based on my own experience and preferences in building web applications. At its core lies the pursuit of modularity, flexibility, and adaptability to changes.

This philosophy touches on both specific aspects of web development and broader architectural concerns relevant to programming in general. Its principles aim to simplify code organization, reduce unnecessary complexity, and enhance project structure and adaptability.

It is important to note that my experience focuses on developing modular monoliths, rather than microservices or high-load systems. The primary focus is on creating an architecture that is convenient for development and maintenance, without unnecessary overhead associated with breaking an application into multiple services.

The ideas presented here do not require complex theoretical studies—their strength lies in simplicity and clarity. They help build systems that are easy to develop and maintain. Tequila Framework (TeqFW) serves as an example of the implementation of these principles, providing a platform for experimentation and the search for new solutions.

Core Principles of TeqFW

1. Unified Language for Development: Using JavaScript (ES6+) at all levels of an application. This reduces complexity, eliminates barriers between frontend and backend, and creates a unified ecosystem.

2. Late Binding: Adapting proven enterprise solutions from Java, C#, and PHP for JavaScript. An object container ensures dynamic dependency management through ES6 module namespaces, simplifying the development of modular applications.

3. Evolutionary Code Resilience: The code is designed with inevitable changes in mind to minimize adaptation costs and simplify expansion without modifying existing components.

4. Separation of Concerns: Isolation of data structures (DTOs) and logic handlers. This approach makes the code easier to test, maintain, and reuse.

5. Namespaces: Each type of entity—npm packages, ES6 modules, database tables, CLI commands, or configurations—has its own namespace. This ensures clear project structure, reduces conflicts, and simplifies code navigation.

6. No Transpilation: Using modern JavaScript with JSDoc annotations instead of TypeScript. This approach simplifies working with code, making it more accessible and transparent, which is especially important for integrating third-party libraries.

7. LLM Integration into Development: Architecture, code, and documentation are designed so that language models can participate in development. This requires a clear structure, standardized templates, and minimal hierarchy, which simplifies automation and the generation of new components.

Principle Details

Unified Language for Development

Using JavaScript (ES6+) for both frontend and backend simplifies development and reduces the cognitive load on developers. This approach eliminates barriers between different parts of an application and among team members, creating a unified ecosystem where it is easier to maintain shared development context.

JavaScript remains the only viable high-level language for browsers, and with Node.js, it has become a reliable tool for server-side development. This allows developers to use a single programming language, reducing the gap between client and server code, facilitating teamwork, and simplifying the onboarding of new developers.

A unified language enables teams to flexibly distribute tasks, as developers are less restricted by frontend or backend specialization. It also reduces redundant logic and simplifies knowledge transfer across different parts of the codebase.

Late Binding

This approach adapts proven enterprise solutions from Java, C#, and PHP for JavaScript, ensuring architecture flexibility and simplifying code scalability. Instead of rigidly defined dependencies between modules, dynamic dependency management is used through an object container and ES6 module namespaces.

Such a mechanism reduces the risks of application “breakage” during changes, allows components to be substituted without deep refactoring, and simplifies code maintenance. Late binding also improves testability: dependencies can be replaced with stubs or alternative implementations, making unit testing easier.

In team collaboration, this lowers the barrier to understanding complex system relationships, making it easier to work with new code and ensuring long-term project maintainability.

Evolutionary Code Resilience

The codebase must be resilient to inevitable changes in requirements, APIs, and data to minimize adaptation costs. This is achieved by designing code that can expand without modifying existing components while remaining predictable during changes.

One of the approaches is destructuring function arguments, allowing only the necessary data to be processed. This makes functions more flexible and enables adding new parameters without affecting existing code.

For data structures, the principle of processing only known attributes is applied. When passing DTOs, extra data is ignored, allowing structures to be expanded without rewriting handlers. This method is especially important for scalable systems where data formats may evolve over time.

Other methods to ensure resilience include:

• Using strict contracts (interfaces) for component interactions.
• Avoiding rigid dependencies on specific implementations (see Late Binding principle).

Separation of Concerns

The principle of strict separation between data and logic makes code more predictable and easier to analyze. This approach is based on the Separation of Concerns concept, ensuring a clear distinction between data structures and their processing.

Data is represented as Data Transfer Objects (DTOs), which act as structured data containers. They are used both on the client and server, simplifying reuse. Logic is implemented in handlers that operate on data while remaining isolated from their internal structure.

Such separation reduces complexity in team collaboration, making code more predictable and modular. Isolated handlers are easier to test and modify, preventing uncontrolled growth of logic and improving resilience to changes.

Namespaces

Namespaces are used to establish a clear hierarchy in code, simplifying navigation and preventing conflicts between components. Each type of entity—npm packages, ES6 modules, database tables, CLI commands, or configurations—has its own namespace, making addressing elements within a project predictable.

This approach is especially useful for modular applications and distributed systems, where components are developed independently. Namespaces help teams maintain code consistency and avoid situations where different system parts unexpectedly overlap.

A well-structured namespace organization makes code easier to maintain, as developers can quickly find required elements without the risk of duplication or naming conflicts. It also simplifies the integration of new modules and third-party libraries by setting a unified standard for addressing and naming.

No Transpilation

Tequila Framework uses modern JavaScript (ES6+) without conversion to older versions and without strict TypeScript typing. This approach makes code transparent and accessible without requiring additional build tools, simplifying maintenance and speeding up development.

The absence of transpilation reduces complexity: developers work directly with the original code without intermediate transformations, which facilitates debugging. This is particularly useful for small to medium-sized projects where flexibility and speed of changes are crucial.

Instead of strict typing, JSDoc is used, maintaining code navigation and autocompletion in IDEs without imposing TypeScript-related constraints. This simplifies the integration of third-party libraries since developers do not need to adapt them to strict type contracts.

LLM Integration into Development

Language models (LLMs) are becoming a valuable tool in software development, helping analyze, enhance, and generate code. To make this process effective, architecture, code, and documentation must be structured in a way that LLM agents can easily process and understand.

To achieve this, the following principles apply:

• Clear project structure — simplifies analysis and dependency resolution.
• Standardized code templates — help models predict and correctly complete code.
• Minimal hierarchy and flat structures — reduce cognitive load on LLMs, making code easier to interpret.
• Allowance for boilerplate — repetitive structures facilitate automatic transformation and generation.

Such code organization streamlines automation:

• LLMs can quickly analyze and suggest improvements.
• Automatically complete documentation and code comments.
• Generate template-based code while maintaining project style.
• Facilitate adaptation to changes by proposing standard-compliant adjustments.

This approach benefits not only new code generation but also improves existing codebases, reducing routine work for developers and increasing the predictability of architectural decisions.

Conclusion

This document outlines the principles underlying the Tequila Framework (TeqFW). They do not claim to be unique or aligned with mainstream trends, but their strength lies in simplicity and clarity. These principles help build modular monoliths, making code structured, flexible, and predictable in evolution.

It is important to understand that ideas and their implementation are not the same. Implementation may be imperfect, but the principles themselves remain valuable and applicable. They do not require complex theoretical justifications or significant time investment to validate. These are practical concepts that enable developers to focus on writing code rather than dealing with tooling complexity.

TeqFW does not impose strict constraints but illustrates how these ideas can be applied in practice, providing developers with a foundation for experimentation and exploration.
