const isImage = require('is-image');

isImage('2022-02-23-044507.HEIC'); // => false

This file is a picture

when using this module in the browser, webpack 5 complains about no longer polyfilling path.

Perhaps you can depend on path-browserify? Or use just its extname function?

Just found the case, when I have a file with a dots before the actual extention.
Example:

const isImage = require('is-image');
isImage('file.with.dots.mp3'); // => false

@sindresorhus what if such case will be handled by is-image lib?

Error [ERR_REQUIRE_ESM]: require() of ES Module not supported.
Instead change the require of index.js in validator.js to a dynamic import() which is available in all CommonJS modules.

}

Thanks for this module. I just noticed some failed tests

The url example.png is not an image, but is-image says it is an image

The url example.png?size=1&color=b is an image, but is-image says that it is not an image, and I think its because of the query string

While using [email protected], I got the error:

This dependency was not found:

To install it, you can run: npm install --save node:path

ERROR in ./node_modules/is-image/index.js

Downgrade to [email protected] and everything is fine.

Hello.
This module is useless. You just check the extension. Better check the magic numbers of the file for this to work.

I'm using all sorts of ES2015 in my code without issue.
The webpack config I'm running is using babel to transpile with these presets:
presets: ['env', 'stage-0', 'react', 'es2015']
