You can see that in action if you add a Network throttle in the Performance tab of Chrome DevTools. I’m talking about server bandwidth, but the same is true for user data. If a user scrolls down the grid really fast, they will trigger a ton of downloads, and that will compromise the user experience and our bandwidth.If we could configure gatsby-plugin-sharp to put the placeholder images in a separate file instead of adding them as inline base64 strings in a JSON file, this would not be a problem. We have to forget about the progressive loading feature of the gatsby-image component due to bundle size.These plugins (gatsby-transformer-sharp and gatsby-plugin-sharp) allow us to use gatsby-image, a Gatsby wrapper over the img tag that provides optimized image loading. In the next section, I compiled a list with some limitations and potential problems. On top of that, we need to add the Gatsby plugins for sharp, a image manipulation library focused on the web. exports = ) export default Cards Copyįor more performance tips, check this YouTube video from the creator of the react-window library. The Gatsby Image plugin supports four output formats: JPEG, PNG, WebP and AVIF. I it's one of the two static site generators I enjoy using. You can see entire component and website on GitHub. I ended up with this configuration: var netlif圜msPaths = import Img from 'gatsby-image' When performing queries on an image, you need to tell Gatsby whether that image is fixed or fluid. This approach doesn't work with Netlify CMS, because it stores images in a single place. Now let’s grab a handful of specific images. This is where the fun begins! Gatsby assumes that images are colocated with posts. This does the magic making images linked from markdown files responsive. With gatsby-image you can think of all images as falling into one of two categories: Fixed. fixed images have known dimensions, and they require fewer processes to optimise. Uses remark to parse the markdown files into usable data nodes for GraphQL. When performing queries on an image, you need to tell Gatsby whether that image is fixed or fluid. In most cases, you should not change this. For example, if your source image is a PNG, it will generate PNG and WebP images. By default, the plugin generates images in the same format as the source image, as well as WebP. Makes it possible to query Sharp image processing library processed images using GraphQL. The Gatsby Image plugin supports four output formats: JPEG, PNG, WebP and AVIF. gatsby-plugin-sharpĮxposes several image processing functions built on the Sharp. Now let's investigate what do we actually need to make this work. Complexity of plugin based processing pipeline makes it a bit harder to understand than good old static site generators. Looking back I would compare Gatsby to Webpack. Getting started with something as complex as Gatsby.js is always a challenge. Yeah sure, but they didn't use it together with Netlify CMS while using beta of v2 :) Now with Gatsby v2 released things are a bit easier. I thought “Everyone talks that I can have out of the box responsive images and other cool things!”. With the release of Gatsby v3.0 back in March 2021 the old Gatsby Image plugin was been replaced with Gatsby Plugin Image ( gatsby-plugin-image ). The most popular feature, at least from my point of view, is Image Processing with gatsby-transformer-sharp. Time has come and even I got the opportunity to try out currently trending Gatsby.js static site generator.
