TS80005: Import may be converted to a default import - in CI

By Kaveh Alemi·Latchkey

TS80005 is a suggestion diagnostic recommending a namespace import be rewritten as a default import; some CI setups surface or fail on suggestions.

What this error means

tsc (often with --plugins or an editor running suggestions) reports TS80005 on a namespace import that could be a default import.

src/app.ts(1,8): message TS80005: This import may be converted to a default import.

Common causes

How to fix it

Convert to a default import

1. Rewrite the namespace import as a default import where interop allows it

import React from 'react'

Stop failing on suggestions

1. Configure your lint/CI step not to treat suggestion diagnostics as errors if the namespace import is intentional

How to prevent it

• Adopt a consistent import style under esModuleInterop and decide whether suggestion diagnostics should gate CI.
