image-validation

Image validation utility for DOM and Node.js beyond the file extensions

Features

• Validate images in various input formats
• Validate based on image data instead of file extension
• Runs in browser or node.js
• Graceful mode (optional) for failed images
• Comes with CLI

How to use

npm i image-validation
# or
yarn add image-validation

const imageValidation = require('image-validation').default
// or
const { default: imageValidation } = require('image-validation')
// or
import ImageValidation from 'image-validation'

Very simple to run:

// then
ImageValidation('image base64 string, arrays, buffer etc...')
  .then(result => {
    // result is either true or false
  })
// or
const result = await ImageValidation('image base64 string, arrays, buffer etc...')

Configure throwing error or returning false

By default the validation will throw an error for an invalid/corrupt image, but this can be changed to return false and fail gracefully.

const result = await ImageValidation('image base64 string, arrays, buffer etc...', { throw: false })

Why?

Allows you to detect image corruption automatically which is very useful in workflows. Technically the image corruption must be fixed at source, but this is not always a possibility. In the future I'd like to add security scanning for metadata exploits and such.
