Businesses often face challenges maintaining an organized and scalable Angular project structure, mostly with large, complex software projects. Features spread across folders, critical functionalities get buried deep within the code, and maintaining it becomes a constant struggle.
This is especially true as applications become more complicated. A messy folder structure with scattered files can lead to development bottlenecks, slowing your team's efficiency and, ultimately, impacting project timelines and budgets.
Here at Jalasoft, our team of expert developers understands this challenge, the importance of a well-planned Angular project, and its impact on business revenue.
In this article, we'll look at how a project in Angular works and how to make development workflows and folder structures more efficient using the Angular CLI. By optimizing your project structure, you'll enhance code maintainability, improve collaboration, and ensure scalability as your Angular application grows over time.
Understanding Angular Project Structure
An Angular project's structure goes beyond folders or files. It's the foundation upon which your application is built. But, while it might seem like a technical detail, a clear structure offers significant advantages throughout the development lifecycle of an app.
Let's analyze the structure of an Angular project:
The source folder (src):
As its name says, it contains all the essential source files required for the development. Within this folder, you'll find several subfolders, each playing specific roles:
The application folder (app): This is the heart of your project structure and contains components, services, directives, and several other building blocks that allow developers to create the user interface and manage data through services.
The assets folder: When using Angular, here you'll store static assets like images, fonts, and other configuration files. These components are integrated into the app's code and used in various features like templates.
The environments folder: This folder stores environment-specific configuration files typically used for developing the project and the application, allowing teams to tailor settings based on the deployment stage.
The node_modules folder:
Here is where external libraries and packages used in a project are managed. These dependencies are installed using package managers.
The angular.json file:
This configuration file is crucial for customizing the building process and deployment of an Angular app, serving as a control panel for tailoring the behavior of Angular CLI commands and other configurations for different
Here's why the structure of a project is key:
Enhanced maintainability: In any project, a clear structure allows you to create an organized and easy-to-read code. Like a toolbox, services and other files are grouped following a logic, making it easier for developers to find what they need and understand how different application components interact.
Improved reusability: By organizing reusable components, directives, and pipes into a dedicated shared module, you can easily incorporate them across various features within your application. As a result, code duplication is out of the equation, ensuring a consistent user experience.
Modular development: Core functionalities like routing and global configurations are stored in a core module, while specific features get their feature module. This leads to a cleaner separation of concerns and simplifies the development process by allowing developers to focus on particular features without stressing about dependencies.
Scalability and efficiency: A tightly organized project in Angular scales efficiently as your application becomes more complex. New features can be easily integrated by creating new modules without affecting existing ones.
Angular Project Structure Best Practices
A solid project structure will determine the application's success when building successful applications using Angular. It directly impacts maintainability, scalability, and its ability to drive revenue. That's why Jalasoft's software engineers can help you implement best practices to ensure your application is built for success.
Here are some key best practices forprojects in Angular:
Modularize with feature modules: Break down your application by feature. Each feature gets its module, enclosing its components, services, and other functionalities. By doing this, you will minimize the maintenance workload.
Leverage shared modules: Store reusable components in a separate shared module to eliminate duplicated code.
Organize with core modules: Try to host general configurations and application-wide services in a core module. This keeps these essential elements organized and easily accessible throughout your application.
Lazy loading: It delays the execution of less critical features until they are required, improving load times and user experience for complex or larger apps.
Maintain a separation of concerns: Focus components on UI and services on data. You will simplify updates and any feature addition without affecting other app components.
Use the Angular style guide: This resource encompasses several aspects, including project structure, coding conventions, and architectural patterns. Following these guidelines, your code maintains consistency, facilitating its readability.
Improving An Angular Project’s Structure Through Refactoring
Even top-performing Angular projects can benefit from revisiting its structure over time. As features change and the application grows, refactoring becomes essential to extend the lifespan of a project while setting the stage for its sustainable growth and scalability.
Here's a straightforward guide for an effective refactoring process:
Analyze the current structure: Thoroughly examine your project's folder and file organization. Identify areas where code might be scattered, modules might lack focus, or functionalities could be better grouped.
Define a target structure: Based on your analysis, determine the ideal structure for your project. Consider the best practices we have discussed above. Utilize resources like the Angular guidelines to organize your roadmap.
Create a backup: Before making changes, you should create a comprehensive project backup. This will be your safety net if any issues arise during refactoring.
Refactor one feature at a time: Break down the refactoring process into manageable steps. Focus on refactoring one section at a time. This will help you have more control and easily identify and take care of any potential issues within the code.
Move files and update imports: Following your plan, carefully move files and folders to their designated locations within the new structure of components and modules. Ensure all imports within your components and services are updated to reflect the new file paths.
Test and validate: After refactoring, thoroughly test your application to ensure everything functions as expected. This iterative approach helps identify and address any regressions introduced in the code during the process.
