models.ts
Overview
The [models.ts](/projects/291/68901) file defines data structures used throughout the application, primarily focusing on the shape and validation status of data entities. Currently, this file contains a single interface, `ValidationResult`, which models the outcome of a validation operation. This interface serves as a standardized way to represent whether a particular piece of data or an operation is valid or not.
By encapsulating validation results in this interface, the system components that perform validation or consume validation results can communicate more clearly and consistently. This approach supports maintainability and allows easy extension if additional validation details (such as error messages) need to be included in the future.
Interface: ValidationResult
Description
`ValidationResult` represents the outcome of a validation process. It provides a simple contract indicating whether the validation passed or failed.
Structure
export interface ValidationResult {
valid: boolean;
}
Properties
Property | Type | Description |
|---|---|---|
valid | boolean | Indicates if the validation was successful (`true`) or not (`false`). |
Usage Example
Suppose there is a function that validates a user input form. It can return a `ValidationResult` to indicate the success of the validation:
import { ValidationResult } from './models';
function validateUserName(name: string): ValidationResult {
const isValid = name.trim().length > 0;
return { valid: isValid };
}
// Usage
const result = validateUserName("Alice");
if (result.valid) {
console.log("User name is valid.");
} else {
console.log("User name is invalid.");
}
Implementation Details
The interface is minimalistic, containing only a single boolean property to indicate the validity state.
This simplicity facilitates broad reuse across different validation scenarios without enforcing rigid validation logic.
The design allows for easy extension; for example, future versions could add error messages or codes if needed.
Interaction with Other System Components
Validation Modules: Components responsible for validating data (such as form inputs, API responses, or business rules) can return objects conforming to
ValidationResult.Business Logic Layer: May consume these validation results to decide on workflow branching, error handling, or user feedback.
User Interface Layer: Can interpret
ValidationResultobjects to display validation states, such as success indicators or error prompts.
Since this interface is foundational and generic, it is likely imported and used in multiple parts of the codebase where validation occurs.
