Gatsby transformer plugin for images using Sharp
The gatsby-transformer-sharp package is a Gatsby plugin that allows you to transform images using the Sharp image processing library. It provides a variety of image processing functionalities such as resizing, cropping, and creating responsive images.
Resize Images
This feature allows you to resize images to specified dimensions. The code sample demonstrates how to resize images to 200x200 pixels using the resize method.
exports.createPages = ({ graphql }) => {
return graphql(`
{
allFile {
edges {
node {
childImageSharp {
resize(width: 200, height: 200) {
src
}
}
}
}
}
}
`).then(result => {
console.log(result.data.allFile.edges);
});
};
Generate Thumbnails
This feature allows you to generate fixed-size thumbnails. The code sample demonstrates how to create thumbnails of 125x125 pixels using the fixed method.
exports.createPages = ({ graphql }) => {
return graphql(`
{
allFile {
edges {
node {
childImageSharp {
fixed(width: 125, height: 125) {
src
}
}
}
}
}
}
`).then(result => {
console.log(result.data.allFile.edges);
});
};
Create Responsive Images
This feature allows you to create responsive images that adapt to different screen sizes. The code sample demonstrates how to create fluid images with a maximum width of 800 pixels using the fluid method.
exports.createPages = ({ graphql }) => {
return graphql(`
{
allFile {
edges {
node {
childImageSharp {
fluid(maxWidth: 800) {
...GatsbyImageSharpFluid
}
}
}
}
}
}
`).then(result => {
console.log(result.data.allFile.edges);
});
};

Imagemin is an image optimization tool that compresses images to reduce their file size. It supports various image formats and can be used to optimize images during the build process. While it focuses on optimization rather than transformation, it can be used alongside gatsby-transformer-sharp for a complete image processing solution.
Jimp is an image processing library for Node.js that provides functionalities such as resizing, cropping, and adding filters. It is similar to Sharp but is written entirely in JavaScript, making it easier to use in environments where native modules are not supported.
