Typing Guidelines

• Avoid any at all cost. The types should work or they indicate a problem.
• Never use as "any" or as unknown as to solve/avoid type errors. The types should work or they indicate a problem.
• Avoid using as to cast to a specific type. The types should work or they indicate a problem.

Exports / Imports

• Never create index barrel files (index.ts, index.js)
• Always use direct imports with named exports
• Always use inline interfaces with function parameters

Examples

Good - Inline interface with function:

export function processData({
  id,
  name,
  options,
}: {
  id: string;
  name: string;
  options: ProcessingOptions;
}): ProcessedResult {
  // implementation
}

Bad - Separated interface:

interface ProcessDataProps {
  id: string;
  name: string;
  options: ProcessingOptions;
}

export function processDAta({
  id,
  name,
  options,
}: ProcessDataProps): ProcessResult {
  // Implementation
}
