High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. NPM will choose which native package should download from registry automatically. And add it to optionalDependencies before release the Major package to npm. Images pretty often get a little blurry when resized, so programs such as Photoshop will often apply some sharpening afterwards to make the images a little crisper.

The other problem is some user may not easily download the binary from GitHub/CDN if they are behind private network (But in most case, they have a private NPM mirror). The problem of this solution is it introduced many other packages to download binary which has not been used by runtime codes. Download it in postinstall script is a common way which most packages do it right now. The other problem is how to deliver prebuild binary to users. Now create a file named server.js and create a basic app of nodejs. sudo apt-get install imagemagick will install the software in our system. So at first we have to install imagemagick in our system, I am using linux with ubuntu. And with N-API, we should never afraid of ABI Compatible. For the image compression task we will use imagemagick package of nodejs. With GitHub actions, we can easily prebuild binary for major platforms. In this section, we will start with GraphicsMagick. Native packages may ask developers who use its to install build toolchain like gcc/llvm, node-gyp or something more. In this tutorial, we will be learning how to work with images in Node.js using both GraphicsMagick and ImageMagick. Release native package is very difficult in old days.

This is the native addon built from lib.rs. WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.After yarn build/npm run build command, you can see package-template.node file in project root. Due to this addition, Sharp like the name suggests has a high speed processing power as it only stores a few regions of the uncompressed image data in the memory freeing up much of the used CPU power and L1/L2/元 cache.
