no-redundant-local-alias

Pass the original local into an object field instead of creating a single-use rename.

redundantAlias Rule source Tests Catalog JSON

Why

An unannotated alias used only by its matching object field adds a second name without adding a contract.

Fix

Write the object property with the original binding, then remove the redundant alias. Keep annotations, captured snapshots and independently useful names.

Examples

Before — flagged The closed primitive return preserves the data-field contract

src/request.ts

export {};
function request(value: string) {
  const accountId = value;
  return { accountId };
}

After — preferred The direct data field needs no local alias

src/request.ts

export {};
function request(value: string) {
  return { accountId: value };
}

Autofix output

src/request.ts

export {};
function request(value: string) {
  return { accountId: value };
}

Before — flagged The property already supplies the name

src/request.ts

function request(value: string) {
  const accountId = value;
  return { accountId };
}

After — preferred Use the original binding

src/request.ts

function request(value: string) {
  return { accountId: value };
}
