The error "StaticImageData is not assignable to type string" typically occurs when you are working with images in a TypeScript project (often with Next.js or a similar framework), and the type of an image import is expected to be a string (such as a URL), but the image is being imported as StaticImageData.
Why This Happens:
In frameworks like Next.js (with the next/image package), when you import an image file (like .jpg, .png, .svg, etc.), the import doesn't directly return a string (the image URL), but instead it returns a StaticImageData object. This object contains various metadata about the image, including:
src: The actual image path (a string),
height: Image's height(in pixels),
width: Image's width (in pixels).
This behavior is part of Next.js's Image Optimization feature, which enables automatic image optimization (resizing, lazy loading, etc.).
The StaticImageData Type:
The type StaticImageData is an object that contains details about the image, and is structured something like this:
interface StaticImageData {
src: string;
height: number;
width: number;
blurDataURL?: string;
}
If you're using an image with the next/image package, the import might look like this:
import myImage from 'path/to/image.png';
Here, myImage will have the StaticImageData type.
