Unused import
Imported module never utilized, causing unnecessary dependencies.
[ FAQ1 ]
What is an unused import?
An unused import occurs when a file or module imports dependencies that aren't referenced or utilized anywhere within that file's logic. Such unnecessary imports clutter the codebase, reduce readability, and can lead to slower build or compilation times. Unused imports are commonly introduced during development or refactoring and can be automatically detected by static analysis tools and linters such as ESLint, which flag these imports as unnecessary or "dead."
[ FAQ2 ]
How to remove unused imports
To remove unused imports, regularly run static analysis or linting tools like ESLint to automatically identify and highlight these redundant dependencies. Utilize automated code formatters or IDE plugins that can quickly detect and remove unused imports during file saving or code review. Perform periodic manual reviews and refactoring sessions to maintain a clean, efficient codebase. Keeping imports minimal and relevant helps enhance readability, simplifies maintenance, and improves build performance.
