RentX CRM TypeScript Configuration

A TypeScript configuration skill for RentX, an open-source real estate CRM platform. This skill enforces type safety with strict null checking while maintaining flexibility for rapid development.

What This Skill Does

Configures the TypeScript compiler for the RentX CRM project with:

Instructions

When working on this TypeScript project, follow these compiler configuration rules:

1. **Enable TypeScript**: Always use TypeScript for new files

2. **Null Safety**: Enforce strict null checks (`strictNullChecks: true`) - explicitly handle null and undefined values

3. **Module System**: Use Node.js module resolution (`moduleResolution: "node"`)

4. **ES Module Interop**: Enable ES module interoperability (`esModuleInterop: true`) for seamless imports

5. **Type Flexibility**: Allow implicit `any` types when needed (`noImplicitAny: false`)

6. **Unused Variables**: Do not warn about unused variables (`noUnusedVars: false`)

7. **JavaScript Files**: Do not allow `.js` files in the project (`allowJs: false`)

8. **Linting**: Disable TypeScript linting in favor of external linters (`lint: false`)

Configuration Details

This configuration balances type safety with developer productivity:

Usage Example

When creating new files or refactoring existing code:

```typescript

// ✅ Good: Explicit null handling

function getUser(id: string): User | null {

const user = findUser(id);

if (!user) {

return null;

}

return user;

}

// ✅ Allowed: Using any when type is unclear

function processDynamicData(data: any) {

// Quick prototyping allowed

}

// ✅ Allowed: Unused variables won't trigger warnings

function handleEvent(event: Event, _metadata: unknown) {

console.log(event);

}

```
