What is TypeScript?
TL;DR
Strongly-typed JavaScript superset used throughout Frontend Accelerator for compile-time error checking and superior developer experience.
TypeScript is the foundation of Frontend Accelerator's codebase, providing static type checking that eliminates entire classes of runtime errors and enables powerful AI-assisted development.
1. Sample tsconfig:
// tsconfig.json
{
"compilerOptions": {
"strict": true,
"noImplicitAny": true,
"forceConsistentCasingInFileNames": true,
"module": "esnext"
// etc...
}
}
2. Automatic type generation:
- NextAuth generates session types
- API routes have inferred request/response types
3. AI-friendly type system:
Strong typing enables AI tools to:
- Autocomplete API properties accurately
- Catch errors before runtime
- Understand function contracts instantly
- Refactor code safely across the entire codebase
// Type-safe database query
async function getUser(id: string): Promise<User | null> {
return await db.getUser<User>(id);
}
Benefits:
- Compile-time safety: Catch bugs during development, not production
- IDE autocomplete: Full IntelliSense for all APIs and custom code
- Self-documenting: Types serve as inline documentation
- Refactoring confidence: Rename, move, and modify code fearlessly
Frontend Accelerator's TypeScript configuration ensures maximum safety and AI comprehension.
