Struggling to create a TypeScript definition file - the JSX element 'SideMenu' lacks any construct or call signatures

I am currently working on creating a type definition file for react-native-side-menu in order to properly declare it. I have integrated it into a TypeScript project, but unfortunately, there are no TypeScript definitions available.

Normally, my approach is:

declare module 'react-native-side-menu' {
  export class SideMenu {any}
}

This method has been successful with other libraries, but when I try this with react-native-side-menu, I encounter the following error messages:

$ ./node_modules/.bin/tsc --alwaysStrict --skipLibCheck --watch

[12:37:41] File change detected. Starting incremental compilation...

app/views/Movies.tsx:85:8 - error TS2604: JSX element type 'SideMenu' does not have any construct or call signatures.

85       <SideMenu menu={menu}>
          ~~~~~~~~


app/views/Actors.tsx:80:8 - error TS2604: JSX element type 'SideMenu' does not have any construct or call signatures.

80       <SideMenu menu={menu}>
          ~~~~~~~~


[12:37:41] Found 2 errors. Watching for file changes.

(I'm importing it like this:

import SideMenu from 'react-native-side-menu'
and it functions correctly within the application. My goal is simply to eliminate the TypeScript error message.)

Is there a proper way to declare this module with TypeScript?

Answer №1

  1. Avoid using any within your class definition as it can lead to errors.
  2. You can omit type parameters, as the default values are represented by {}.
  3. If you are familiar with the props accepted by SideMenu, you can specify them in your declaration (e.g., Props).

react-native-side-menu.d.ts

declare module 'react-native-side-menu' {
  import { Component } from 'react'

  interface Props {}

  export default class SideMenu extends Component<Props> {}
}

Answer №2

After some troubleshooting, I realized that the issue was due to omitting a crucial default statement (specifically in the form of export default class ...). Here is how I resolved it:

declare module 'react-native-side-menu' {
  import { Component } from 'react'

  export default class SideMenu extends Component<any, any> { }
}
