Coding Standards
The purpose of the coding standards is to establish a set of guidelines and best practices that govern the development process and ensure consistent, readable, and maintainable code. These standards serve as a reference for developers, helping them write code that is easily understandable, modular, and adheres to industry-recognized conventions. By promoting uniformity in code structure, naming conventions, formatting, and documentation, coding standards enhance collaboration among team members and facilitate code reviews. They also contribute to code quality, reduce the likelihood of introducing bugs, improve readability, and simplify maintenance and troubleshooting. Additionally, coding standards support the scalability of projects by making the codebase more manageable and comprehensible, even as it grows in complexity.
Inline comments should be added when dealing with complex actions or logic that cannot be easily understood just by reading the code. Here are some scenarios where inline comments are particularly useful:
-
Complex algorithms: When implementing intricate algorithms or complex mathematical operations, inline comments can clarify the logic behind the code, outline the steps involved, and provide insights into any underlying assumptions or optimizations.
-
Non-obvious or unconventional code: If the code deviates from standard practices or includes unconventional solutions, inline comments can explain the reasoning behind the approach and help others understand the intention behind the code.
-
Tricky edge cases: When handling exceptional or edge cases, such as boundary conditions or error scenarios, inline comments can describe the specific conditions being addressed and why they are handled in a particular way.
-
Optimizations or performance considerations: If the code includes optimizations for efficiency or performance, inline comments can detail the trade-offs made, highlight any potential risks or caveats, and explain the performance benefits achieved.
-
Integration points or dependencies: When integrating with external systems, libraries, or APIs, inline comments can clarify the purpose, parameters, and expected behavior of the integration points, ensuring seamless collaboration and understanding.
-
Code hacks or workarounds: In situations where code hacks or workarounds are employed, inline comments can justify their use, mention any known limitations, and provide insights into potential risks or alternative approaches.
-
Non-intuitive code or complex business rules: Inline comments can shed light on non-intuitive code or complex business rules, allowing developers to understand the underlying requirements and helping future maintainers navigate the intricacies of the system.
Remember, the goal of inline comments is to provide additional context and aid in code comprehension. They should be concise, and focused, and provide relevant information that cannot be easily inferred from the code alone.

They handle client-server communication and serve as delegates for accessing server-side functionality. Additionally, these libraries also handle all aspects of state management within the application.
Feature Library: A collection of files within a feature library configures a particular business scenario or a page within an application. The majority of these files consist of intelligent components that communicate with data sources. Additionally, this type of library encompasses a significant portion of the user interface logic, form validation code, and other related functionalities. Feature libraries are typically customized for specific applications and are frequently loaded on demand for optimized performance.
UI Library: A user interface (UI) library is a compilation of interconnected presentation components. Typically, these components do not rely on injected services, and instead, they obtain the necessary data through inputs.
Utils Library: A utility library comprises low-level code that is shared among multiple libraries. It is commonly employed for models and interfaces that are utilized throughout the system.
To promote code reuse and avoid duplication, it is crucial for developers to adhere to the practice of placing reusable code in a library whenever it is duplicated or expected to be used in multiple locations. By consolidating such code into a library, developers can create a centralized and well-maintained repository of reusable components, functions, or modules. This approach not only reduces redundancy and improves efficiency but also ensures consistent behavior and simplifies future updates or modifications. Placing reusable code in a library facilitates easier access, promotes modular design, and enhances collaboration among team members. Additionally, it allows developers to focus on creating high-quality, purpose-specific code in their respective projects, leveraging the shared resources available in the library. Embracing this practice ultimately leads to streamlined development processes, optimized codebases, and more efficient software development lifecycles.
To adhere to the naming conventions, it is required that all module files are named based on their respective features. For example, a login module file should be named "login.module.ts". Similarly, for each page, the file name should consist of the feature name followed by the keyword "page". For instance, a login page file should be named "login.page.ts". For component files, it is essential to provide descriptive names. The file names should include the keyword "component" as a suffix. For example, a component file for a recipe card should be named "recipe-card.component.ts".
Developers should prioritize the use of descriptive variable names as it greatly enhances code readability and maintainability. Choosing meaningful and self-explanatory names for variables improves the understanding of code logic, making it easier for both the original author and other developers to comprehend the purpose and functionality of each variable. Descriptive variable names help convey the intention and context of the data being stored, leading to more intuitive and self-documenting code. By avoiding generic or ambiguous names, developers can prevent confusion and reduce the likelihood of introducing bugs or errors. Additionally, clear and descriptive variable names contribute to efficient code reviews, troubleshooting, and collaboration among team members. Investing time and effort into choosing appropriate names for variables pays off in the long run, making code more readable, and maintainable, and ultimately enhancing the overall quality of the software.
In the CI/CD pipeline, there is a comprehensive testing framework to ensure the quality and correctness of every change. The pipeline encompasses a series of automated tests, including unit tests, integration tests, and end-to-end tests. These tests validate the functionality of the codebase, making certain that any modifications or additions do not introduce unexpected issues or regressions. Additionally, the pipeline incorporates a robust linting process, which enforces code style guidelines and detects potential syntax errors, improving code consistency and maintainability. Furthermore, the pipeline includes build testing, which verifies that the software can be successfully compiled and packaged. To streamline the deployment process, an automated deployment mechanism is integrated into the pipeline. This mechanism facilitates the seamless deployment of verified changes to the target environment, minimizing the risk of human error and ensuring that only correct and validated changes are pushed to production.
When reviewing code changes, it is essential for developers to thoroughly examine the modified files and execute the application to ensure the intended functionality is achieved. By carefully reviewing the changed files, developers can gain a comprehensive understanding of the alterations made and evaluate their impact on the overall codebase. Running the application provides an opportunity to observe the changes in action and validate their behavior in different scenarios and environments. In addition to running the application, developers should perform quality assurance testing to verify that the changes align with the project's requirements and standards. This testing process can include functional testing, performance testing, security testing, and any other relevant tests that help ensure the quality and integrity of the code changes. By combining comprehensive file review, application execution, and quality assurance testing, developers can confidently assess the impact of code changes and identify any potential issues or areas that require further improvement.
During code reviews, it is crucial for developers to effectively communicate their concerns and suggestions for improvements. When requesting changes, developers should clearly articulate the specific issues they have encountered within the codebase. By providing detailed explanations and referencing specific lines of code, they can precisely pinpoint the areas that require attention or modification. This approach enhances clarity and ensures that all parties involved have a common understanding of the problem at hand. Referencing specific lines not only helps in identifying the exact location of the issue but also assists in facilitating focused discussions and expedites the resolution process. Clear and specific communication during code reviews fosters collaboration, promotes efficient problem-solving, and ultimately leads to higher code quality and maintainability.
