TypeScript Patterns — CEI-001

Type Safety Strictness

// tsconfig.json
{
  "compilerOptions": {
    "strict": true,
    "noImplicitAny": true,
    "noImplicitThis": true,
    "strictNullChecks": true,
    "strictFunctionTypes": true,
    "strictBindCallApply": true,
    "strictPropertyInitialization": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true
  }
}

Enums for Constants

// types/evaluation.ts
export enum ModuleType {
  VISION = 'vision',
  ORGANIZATION = 'organization',
  DATA = 'data',
  INFRASTRUCTURE = 'infrastructure',
  RESOURCES = 'resources',
  PITFALLS = 'pitfalls',
  IMPLEMENTATION = 'implementation',
  POST = 'post'
}

export enum QuestionType {
  YESNO = 'yesno',
  SCALE = 'scale',
  MULTIPLE = 'multiple'
}

export enum EvaluationStatus {
  IN_PROGRESS = 'in_progress',
  COMPLETED = 'completed',
  DRAFT = 'draft'
}

Discriminated Unions

// types/api.ts
type ApiResponse<T> =
  | { type: 'success'; data: T }
  | { type: 'error'; error: { code: string; message: string } }
  | { type: 'loading' };

// Type-safe usage
function handleResponse<T>(response: ApiResponse<T>) {
  if (response.type === 'success') {
    console.log(response.data); // T is available
  } else if (response.type === 'error') {
    console.log(response.error.code); // error is available
  }
}

Generics

// API client with generics
interface ApiClient {
  get<T>(url: string): Promise<T>;
  post<T, D>(url: string, data: D): Promise<T>;
  put<T, D>(url: string, id: string, data: D): Promise<T>;
}

// Usage
const users = await api.get<User[]>('/api/users');
const created = await api.post<User, CreateUserData>('/api/users', userData);

Custom Hooks with Types

// hooks/usePagination.ts
interface UsePaginationOptions {
  pageSize: number;
  initialPage?: number;
}

interface UsePaginationState {
  page: number;
  total: number;
  pageSize: number;
}

export function usePagination({
  pageSize,
  initialPage = 1
}: UsePaginationOptions) {
  const [state, setState] = useState<UsePaginationState>({
    page: initialPage,
    total: 0,
    pageSize
  });

  const nextPage = () => setState(prev => ({
    ...prev,
    page: Math.min(prev.page + 1, Math.ceil(prev.total / pageSize))
  }));

  const previousPage = () => setState(prev => ({
    ...prev,
    page: Math.max(prev.page - 1, 1)
  }));

  return { ...state, nextPage, previousPage };
}

Form Validation with Zod

// validation/evaluation.ts
import { z } from 'zod';

export const answerSchema = z.object({
  questionId: z.string().uuid(),
  answer: z.enum(['oui', 'non', 'partiellement']),
  comment: z.string().optional()
});

export type Answer = z.infer<typeof answerSchema>;

export const evaluationSchema = z.object({
  companyId: z.string().min(1),
  answers: z.array(answerSchema)
});

export type EvaluationData = z.infer<typeof evaluationSchema>;

// Usage with React Hook Form
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';

export function AnswerForm() {
  const { control, handleSubmit } = useForm<Answer>({
    resolver: zodResolver(answerSchema)
  });
  
  return (
    <form
      {/* Form fields */}
    </form>
  );
}

Utility Types

// Type helpers
type Readonly<T> = {
  readonly [P in keyof T]: T[P];
};

type Partial<T> = {
  [P in keyof T]?: T[P];
};

type Record<K extends string | number | symbol, T> = {
  [P in K]: T;
};

// Usage
type UserResponse = Readonly<User>;
type UserUpdate = Partial<User>;
type UserMap = Record<string, User>;

Async Types

type ApiResult<T> = Promise<T | null>;

async function fetchUser(id: string): ApiResult<User> {
  try {
    const response = await api.get<User>(`/api/users/${id}`);
    return response;
  } catch (error) {
    console.error(error);
    return null;
  }
}

Conventions

• Interfaces for public APIs, types for internal
• Enums for constants instead of as const
• Generics for reusable logic
• Discriminated unions for variants
• Zod for runtime validation
• Strict mode always enabled
• No any type allowed
• Export types from types/ folder
