Typescript react - Could not find a declaration file for module ''react-materialize'. 'path/to/module-name.js' implicitly has an any type

Question

I am trying to import components from react-materialize as -

import {Navbar, NavItem} from \'react-materialize\';

But when the webpack is

Answer 1

For my case the issue was that the types were not getting added to package.json file under devDependencies to fix it I ran npm install --save-dev @types/react-redux note the --save-dev

Answer 2

I had this issue when I added react-router-dom to the new CRA app using typescript. After I added @types/react-router, the issue was fixed.

Answer 3

A more hacky way is to add eg., in boot.tsx the line

import './path/declare_modules.d.ts';

with

declare module 'react-materialize';
declare module 'react-router';
declare module 'flux';

in declare_modules.d.ts

It works but other solutions are better IMO.

Answer 4

works just fine

npm install @types/react-materialize

Answer 5

I had a similar error but for me it was react-router. Solved it by installing types for it.

npm install --save @types/react-router

Error:

(6,30): error TS7016: Could not find a declaration file for module 'react-router'. '\node_modules\react-router\index.js' implicitly has an 'any' type.

If you would like to disable it site wide you can instead edit tsconfig.json and set noImplicitAny to false.

Answer 6

Also, this error gets fixed if the package you're trying to use has it's own type file(s) and it's listed it in the package.json typings attribute

Like so:

{
  "name": "some-package",
  "version": "X.Y.Z",
  "description": "Yada yada yada",
  "main": "./index.js",

  "typings": "./index.d.ts",

  "repository": "https://github.com/yadayada.git",
  "author": "John Doe",
  "license": "MIT",
  "private": true
}
