Bug description

Fresh installation of Vite with React and TypeScript using Swiper version 9.3.2. I am getting the following error:

Could not find a declaration file for module 'swiper'. 

'/.../node_modules/swiper/swiper.esm.js' implicitly has an 'any' type.

There are types at '/.../node_modules/swiper/swiper.d.ts', but this result could not be resolved when respecting package.json "exports".

The 'swiper' library may need to update its package.json or typings.ts

Here's my code:

// Swiper modules
import { Keyboard } from "swiper"; // This is the problem

// Swiper React components
import { Swiper, SwiperSlide, SwiperRef, SwiperClass } from "swiper/react"; // This is fine

// Swiper styles
import "swiper/css"; // This is fine

Expected Behavior

Types should just work without error.

Actual Behavior

Type error.

Swiper version

9.3.2

I've got the same issue. Did you manage to find a way to fix it?

Please check this PR: #6626
You need to change exports in swiperjs's package.json. I tried and it's working fine now.

Solution:

1. Create a swiper.d.ts file in your application folder
2. Inside the file, place the following line of code:
   declare module 'swiper'

Thank you so much @salvadoregunacci for the solution.
But how should I fix the bug when deploying a website ? I am getting a build error of the same on vercel.

@paras1729kori
You can try this solution:
in your tsconfig file add the following code

"compilerOptions": {
"noImplicitAny": false
}

P.S it's not the best option, but it might come in handy

Thanks a bunch @salvadoregunacci. It worked.

It helps for me:
"strict": true -> "strict": false

in your tsconfig.json

Got same error today while migrating nextjs project to esm. tsconfig moduleResolution = bundler

Im just copy-pasted declaraions from swiper.d.ts into my project's global.d.ts

declare module 'swiper' {
  import Swiper from './types/swiper-class'
  import { SwiperOptions } from './types/swiper-options'
  import { SwiperModule } from './types/shared'

  declare const A11y: SwiperModule
  declare const Autoplay: SwiperModule
  declare const Controller: SwiperModule
  declare const EffectCoverflow: SwiperModule
  declare const EffectCube: SwiperModule
  declare const EffectFade: SwiperModule
  declare const EffectFlip: SwiperModule
  declare const EffectCreative: SwiperModule

  declare const Thumbs: SwiperModule
  declare const Virtual: SwiperModule
  declare const Zoom: SwiperModule
  declare const FreeMode: SwiperModule
  declare const Grid: SwiperModule

  export default Swiper

what worked for me in Next.js 13 was using swiper instead of swiper/module that was written in the documentation.
import { Navigation, Pagination, Scrollbar, A11y } from "swiper";
