@expo/image-utils
Advanced tools
@expo/image-utilsA library for image processing functionality in Expo CLI. It uses sharp for image processing if it's available through a global sharp-cli installation. Otherwise it uses jimp, a Node library with no native dependencies, and warns the user that they may want to install sharp-cli for faster image processing.
This package can be configured using the following environment variables.
When truthy, this will force global sharp-cli resolution methods like isAvailableAsync() and findSharpInstanceAsync() to fail. Other processes can use this to fallback on Jimp for image modifications. By default this is falsy (undefined).
findSharpInstanceAsync() will throw an error if disabled because it shouldn't be invoked if isAvailableAsync() returns false.
Sharp is a high-performance image processing library that supports resizing, cropping, compositing, and format conversion. It is known for its speed and efficiency, making it a popular choice for server-side image processing. Compared to @expo/image-utils, Sharp offers more advanced features and better performance but may be more complex to set up and use.
Jimp is a JavaScript image processing library that works in both Node.js and the browser. It supports a wide range of image manipulation tasks, including resizing, cropping, and color adjustments. Jimp is easier to use and more versatile than @expo/image-utils, but it may not be as performant for large-scale image processing tasks.
GraphicsMagick (gm) is a Node.js wrapper for the GraphicsMagick and ImageMagick command-line tools. It provides a wide range of image processing capabilities, including resizing, cropping, and format conversion. While gm offers extensive functionality, it requires the installation of external dependencies, making it more complex to set up compared to @expo/image-utils.
