Anatomy of an Angular Workspace

As a Technical Lead, you know that project architecture is the foundation of scalability. When you run ng new, Angular generates a strictly defined workspace. Following this standard structure allows multiple developers to collaborate seamlessly, as every file has a predictable home. In a clean architecture approach, we separate our core logic from our UI and our configuration.

Root Configuration Files

The root of your project contains configuration files that govern the entire workspace, from build settings to dependency management.

angular.json: The CLI configuration. It defines how your app is built, served, and tested.
package.json: Manages your NPM dependencies and scripts (like npm start).
tsconfig.json: Configures the TypeScript compiler options for the project.
src/: The heart of the application where all source code lives.

The 'src' Folder

Inside src, you find the files that actually get compiled into your web application. This is where the 'magic' happens.

Folder/File	Description
app/	Contains the components, services, and modules of your application.
assets/	Stores static files like images, icons, and global configuration JSONs.
environments/	Holds environment-specific variables (e.g., API URLs for Dev vs Prod).
index.html	The main HTML page served to users; Angular injects your app here.
main.ts	The entry point for the application that bootstraps the root module.
styles.scss	Global CSS/SCSS styles applied to the entire application.

The 'app' Folder Structure

Inside src/app, a common professional pattern is to group files by feature or type. For a complex tool like Revochamp, you might see subfolders like core/ (for singleton services), shared/ (for reusable UI components), and features/ (for specific app modules).

File Naming Conventions

Angular uses a specific naming convention: name.type.extension. For example, a component for user profiles would be named user-profile.component.ts. This makes it immediately obvious what each file does without opening it.

Frequently Asked Questions

What is the 'app.module.ts' file?

This is the Root Module. It tells Angular how to assemble the application by declaring which components belong to it and which external modules (like HttpClientModule) it needs.

Should I keep CSS inside the component file?

While Angular allows 'inline' styles, as an architect, I recommend using separate '.scss' files. It keeps your logic (TS) and design (CSS) clean and separated, following the Single Responsibility Principle.

Where should I put my Gemini API keys?

Never put keys in source code. Store them in 'src/environments/environment.prod.ts' for production or use a backend proxy so your keys are never exposed to the frontend browser.
