Internal API Endpoint +### Polymorphism: Why Strategy Pattern over if/else? -You must expose **one single endpoint** in your application: ```GET /api/finance/data/{resourceType}``` +The Strategy Pattern was chosen over a conditional block (`if/else` or `switch`) in the service layer for the following reasons: -Where `{resourceType}` can be one of the three strings: `latest_idr_rates`, `historical_idr_usd`, or `supported_currencies`. +**Extensibility (Open/Closed Principle):** Adding a new `resourceType` (e.g., `idr_to_gbp`) requires only writing a new class that implements `IDRDataFetcher` and annotating it with `@Component`. The controller, service, and data store require **zero changes**. With a `switch` block, every new resource type means modifying existing, tested code โ€” increasing regression risk. -### 3. Required Functionality & Business Logic +**Maintainability:** Each concrete strategy class (`LatestIDRRatesFetcher`, `HistoricalIDRUSDFetcher`, `SupportedCurrenciesFetcher`) is a single-responsibility unit. It is independently readable, testable, and deployable. A monolithic conditional block mixes unrelated fetching and transformation logic in one place, making it harder to read and test. + +**Spring's Auto-Discovery:** Spring automatically discovers all `IDRDataFetcher` beans and injects them as a `List` into `FinanceDataService`. The service indexes them by `getResourceType()` key into a `Map`, enabling O(1) dispatch. This is idiomatic Spring โ€” no manual registry maintenance required. -* **Resource Handling:** Your service must correctly map the three incoming `resourceType` values to the correct data fetching strategies. +**Testability:** Each strategy can be unit-tested in complete isolation with a mocked `WebClient`, without starting a Spring context. -* **Data Load:** All three resources should be fetched from the external API. +--- -* **Data Transformation (Latest IDR Rates only) - Unique Calculation:** For the **`latest_idr_rates`** resource, you must calculate and include a new field, `"USD_BuySpread_IDR"`. This is the Rupiah selling rate to USD after applying a banking spread/margin. +### Client Factory: Why FactoryBean over @Bean? - **The Spread Factor Must Be Unique :** +`FrankfurterWebClientFactory` implements `FactoryBean` rather than defining WebClient as a `@Bean` method in a `@Configuration` class. The key benefits: - 1. **Input:** Your GitHub username (e.g., `johndoe47`). - 2. **Calculation:** Calculate the sum of the Unicode (ASCII) values of all characters in your lowercase GitHub username string. - 3. **Spread Factor Derivation:** `Spread Factor = (Sum of Unicode Values % 1000) / 100000.0` - *(This will yield a unique factor between 0.00000 and 0.00999, ensuring a personalized result.)* +**Encapsulation of Construction Logic:** The factory class is the sole owner of all WebClient construction concerns โ€” base URL, timeouts, shared headers, logging filters. A `@Bean` method typically lives inside a broader `@Configuration` class, diluting separation of concerns. The factory is a self-contained, single-purpose class. - **Final Formula:** `USD_BuySpread_IDR = (1 / Rate_USD) * (1 + Spread Factor)` (where `Rate_USD` is the value from the API when `base=IDR`). +**Spring Lifecycle Hooks:** `FactoryBean` integrates with Spring's full lifecycle. `isSingleton()` guarantees a single shared `WebClient` instance. Future enhancements (e.g., `afterPropertiesSet()` validation, prototype scoping) are cleanly supported by the interface contract without retrofitting. -* **Other Resources:** The `historical_idr_usd` and `supported_currencies` resources can return their data with minimal transformation, but the final output must be a unified JSON array of results. +**Validation at Startup:** The factory can validate required properties (e.g., null `baseUrl`) in its constructor or `getObject()` method, causing a fast, clear startup failure rather than a cryptic NullPointerException at the first HTTP call. -## II. Architectural Constraints +**Clarity:** Any developer who sees `@Autowired WebClient webClient` in the strategies immediately knows there is a dedicated factory responsible for its construction โ€” making the codebase easier to navigate. -Meeting the core task is only one part of the solution. The following constraints must be strictly adhered to and will be heavily weighted during evaluation: +--- -### Constraint A: The Strategy Pattern +### Startup Runner: Why ApplicationRunner over @PostConstruct? -The logic for handling the three different resources (`latest_idr_rates`, `historical_idr_usd`, `supported_currencies`) must be implemented using the **Strategy Design Pattern**. +`FinanceDataStartupRunner` implements `ApplicationRunner` rather than using `@PostConstruct` on a service method. The key justifications: -1. Define a clear **Strategy Interface** (e.g., `IDRDataFetcher`). +**Full Context Readiness:** `ApplicationRunner.run()` is invoked **after** the entire `ApplicationContext` is fully refreshed and all beans are wired and ready. `@PostConstruct` fires during the bean initialization phase โ€” before the context is fully ready. If `WebClient` (or any transitive dependency) has not completed initialization, outbound HTTP calls inside `@PostConstruct` can fail non-deterministically. -2. Implement **three concrete strategy classes** (one for each resource). +**Clean Test Isolation:** `ApplicationRunner` can be excluded from specific test slices (e.g., `@WebMvcTest`) without special configuration. `@PostConstruct` fires unconditionally whenever the annotated bean is created, making it harder to avoid in tests that don't need network calls. -3. The main `Controller` should dynamically select the correct strategy implementation using a map-based lookup injected by Spring, avoiding any manual `if/else` or `switch` logic in the controller layer. +**ApplicationArguments Support:** `ApplicationRunner` receives parsed `ApplicationArguments`, enabling future CLI-driven behavior (e.g., `--dry-run`, `--skip-prefetch`) without changing the runner's internal logic. -### Constraint B: Client Factory Bean +**Failure Propagation:** Exceptions thrown from `ApplicationRunner.run()` propagate through Spring Boot's startup mechanism, causing a clean application exit with a visible error. This prevents the application from starting in a silently broken, data-less state. -The instance of your chosen external API client (`WebClient` or `RestTemplate`) **must be defined and created within a custom implementation of Spring's `FactoryBean` interface**. +--- -* This `FactoryBean` should be responsible for externalizing the API Base URL via `@Value` or `@ConfigurationProperties` and applying any initial configuration (e.g., timeouts, shared headers). +## ๐Ÿ“ฆ Technologies -* ***You may not define the client as a simple `@Bean` in a `@Configuration` class.*** - -### Constraint C: Startup Data Runner & Immutability - -The aggregated data for **ALL three resources** must be fetched **exactly once on application startup** and loaded into an in-memory store. - -1. Use a Spring Boot **`ApplicationRunner`** or **`CommandLineRunner`** component to initiate the data fetching process. - -2. The API endpoint (`GET /api/finance/data/{resourceType}`) must serve the data from this **in-memory store**, not by making a new call to the external API on every request. - -3. The in-memory storage mechanism (e.g., a service holding the data) must be designed to be **thread-safe** and ensure the data is **immutable** once the `ApplicationRunner` has finished loading it. - -## III. Production Readiness & Deliverables - -Your final solution must demonstrate production quality through code, testing, and communication. - -### 1. Robustness & Best Practices - -* Graceful **Error Handling** for network failures or 4xx/5xx responses from the external API. - -* Proper use of **Configuration Properties** (e.g., `application.yml`) for external service URLs. - -* Clear separation of concerns (Controller, Service, Model/DTO, etc.). - -### 2. Testing - -* **Unit Tests** for all three `IDRDataFetcher` strategy implementations, ensuring data calculation and transformation logic is covered (using mock clients for external calls). - -* **Integration Tests** to verify the `ApplicationRunner` successfully initializes and loads the data into the in-memory store before the application context is ready. - -### 3. Documentation - -A clear `README.md` is mandatory. It must include: - -* **Setup/Run Instructions:** Clear steps to clone, build, and run the application and tests. - -* **Endpoint Usage:** Example cURL commands to test the three different resource types. - -* **Personalization Note:** Clearly state your GitHub username and show the exact **Spread Factor** (e.g., `0.00765`) calculated by your function. - -* --- - -* ### ๐Ÿ› ๏ธ Architectural Rationale - - This section should contain a brief, but detailed, explanation answering the following questions: - - 1. **Polymorphism Justification:** Explain *why* the Strategy Pattern was used over a simpler conditional block in the service layer for handling the multi-resource endpoint. Discuss the benefits in terms of **extensibility** and **maintainability**. - - 2. **Client Factory:** Explain the specific role and benefit of using a **`FactoryBean`** to construct the external API client. Why is this preferable to defining the client using a standard `@Bean` method in this scenario? - - 3. **Startup Runner Choice:** Justify the choice of using an `ApplicationRunner` (or `CommandLineRunner`) for the initial data ingestion over a simpler `@PostConstruct` method. - -## IV.
