Description
Auto importing should choose the nearest one where same symbol name is exported from multiple files
🔍 Search Terms
auto import
same symbol name
✅ Viability Checklist
My suggestion meets these guidelines:
- This wouldn't be a breaking change in existing TypeScript/JavaScript code
- This wouldn't change the runtime behavior of existing JavaScript code
- This could be implemented without emitting different JS based on the types of the expressions
- This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
- This feature would agree with the rest of TypeScript's Design Goals.
💻 Use Cases
When .vscode/settings.json "typescript.preferences.importModuleSpecifier": "shortest",
The following auto importing behavior is very strange:
// src/app1/config.ts
export const LogLevel=1
// src/app1/main.ts
import {LogLevel} from "src/app2/config"
console.log(LogLevel)
// src/app2/config.ts
export const LogLevel=2
// src/app2/main.ts
import {LogLevel} from "src/app1/config"
console.log(LogLevel)
I think it should auto imports the nearest one, but it auto imports the other one.
When .vscode/settings.json "typescript.preferences.importModuleSpecifier": "relative",
The auto importing behavior is OK:
// src/app1/config.ts
export const LogLevel=1
// src/app1/main.ts
import {LogLevel} from "./config"
console.log(LogLevel)
// src/app2/config.ts
export const LogLevel=2
// src/app2/main.ts
import {LogLevel} from "./config"
console.log(LogLevel)

Research direction
Reproduce the examples using .vscode/settings.json with importModuleSpecifier set to shortest and relative. Compare the auto-import choices for the two app1/app2 config.ts files, then trace the TypeScript auto-import behavior that ranks candidates; done means shortest mode selects the nearest exported symbol in both cases.
