What are some potential disadvantages of using `import type` or activating the `@typescript-eslint/consistent-type-imports` rule in ESLint?

Recently, I encountered an issue that was resolved by utilizing the import type feature in TypeScript instead of just using import. It came to my attention that there exists an eslint rule called 

@typescript-eslint/consistent-type-imports
which, when activated, automatically replaces import with import type through eslint --fix where necessary.

It appears that opting for import type over import whenever possible is quite logical. Supposedly, it allows for optimization during compilation and enhances code readability in certain situations without causing any adverse effects on existing code if applied correctly. In essence, it seems like a beneficial choice with no downsides.

However, I observed that the widely used eslint recommended configurations such as airbnb-typescript or @typescript-eslint/recommended do not include the 

@typescript-eslint/consistent-type-imports
rule. This omission raises doubts about whether this rule might not be as advantageous as it initially appears.

Therefore, are there any potential risks associated with enabling the 

@typescript-eslint/consistent-type-imports
rule within a project?

Answer №1

Implementing that specific rule in a complex monorepo has brought significant benefits. The eslint rule showcases its intelligence by differentiating between usage as a value or type, seamlessly adjusting import statements accordingly.

It's puzzling why the projects you referenced neglect to incorporate this rule. Personally, I have utilized it for several years without encountering any drawbacks.
