I found a solution here: Webpack & Typescript image import
But i am getting error for this:
[ts]
Types of property 'src' are incompatible.
Type 'typeof import("*.png")' is not assignable to type 'string | undefined'.
Type 'typeof import("*.png")' is not assignable to type 'string'.
I guess i need to cast import somehow, but cant figure out how.
I am doing this in React. I saw that src attribute is defined as string | undefined, that is why error is popping.
Here is code:
import * as Logo from 'assets/images/logo.png';
HTML:
<img src={Logo} alt="" />
And definition based on above mentioned solution:
declare module "*.png" {
const value: string;
export default value;
}
Tsconfig:
{
"compilerOptions": {
"baseUrl": "./",
"jsx": "react",
"lib": ["es5", "es6", "dom"],
"module": "commonjs",
"noImplicitAny": false,
"outDir": "./dist/",
"sourceMap": true,
"strictNullChecks": true,
"target": "es5",
"typeRoots": [
"custom_typings"
]
},
"include": ["./src/**/*.tsx"],
"exclude": ["dist", "build", "node_modules"]
}
One of the ways to get rid of that error is by modifying d.ts file as follows:
declare module "*.png"
remove
{
const value: string;
export default value;
}
or alternatively you can do:
declare module "*.png" {
const value: any;
export default value;
}
Update
The best solution with type-checking is:
declare module "*.png" {
const value: any;
export = value;
}
For react-native
create global.d.ts file on project root folder and just add next lines there
declare module '*.png' {
const value: import('react-native').ImageSourcePropType;
export default value;
}
