gatsby-transformer-sharp

Creates ImageSharp nodes from image types that are supported by the Sharp image processing library and provides fields in their GraphQL types for processing your images in a variety of ways including resizing, cropping, and creating responsive images.

Live demo (source)

Install

npm install --save gatsby-transformer-sharp gatsby-plugin-sharp

How to use

// In your gatsby-config.js
module.exports = {
  plugins: [`gatsby-plugin-sharp`, `gatsby-transformer-sharp`],
}

Please note that you must have a source plugin (which brings in images) installed in your project. Otherwise, no ImageSharp nodes can be created for your files. Examples would be gatsby-source-filesystem or source plugins for (headless) CMSs like gatsby-source-wordpress.

Note: An exception to this is when using gatsby-source-contentful, as the source plugin and the assets are not downloaded to the local filesystem. By default, the gatsby-source-contentful plugin creates a ContentfulAsset node for every image with links to Contentful’s CDN, therefore it is not necessary to use gatsby-transformer-sharp together with gatsby-source-contentful.

Parsing algorithm

It recognizes files with the following extensions as images.

  • jpeg
  • jpg
  • png
  • webp
  • tif
  • tiff

Each image file is parsed into a node of type ImageSharp.

Troubleshooting

Incompatible library version: sharp.node requires version X or later, but Z provides version Y

This means that there are multiple incompatible versions of the sharp package installed in node_modules. The complete error typically looks like this:

Something went wrong installing the "sharp" module

dlopen(/Users/misiek/dev/gatsby-starter-blog/node_modules/sharp/build/Release/sharp.node, 1): Library not loaded: @rpath/libglib-2.0.dylib
  Referenced from: /Users/misiek/dev/gatsby-starter-blog/node_modules/sharp/build/Release/sharp.node
  Reason: Incompatible library version: sharp.node requires version 6001.0.0 or later, but libglib-2.0.dylib provides version 5801.0.0

To fix this, you’ll need to update all Gatsby plugins in the current project that depend on the sharp package. Here’s a list of official plugins that you might need to update in case your projects uses them:

  • gatsby-plugin-sharp
  • gatsby-plugin-manifest
  • gatsby-remark-images-contentful
  • gatsby-source-contentful
  • gatsby-transformer-sharp
  • gatsby-transformer-sqip

To update these packages, run:

npm install gatsby-plugin-sharp gatsby-plugin-manifest gatsby-remark-images-contentful gatsby-source-contentful gatsby-transformer-sharp gatsby-transformer-sqip

If updating these doesn’t fix the issue, your project probably uses other plugins from the community that depend on a different version of sharp. Try running npm list sharp or yarn why sharp to see all packages in the current project that use sharp and try updating them as well.
