One of the most important advantages of Gatsby is it's work very fast. Many delays in loading pages are caused by too big and non-optimized images. Gatbsy has several useful plugins that help completely optimize images and maintain great performance on our website.
The recommended approach is to use gatbsy-image – React component designed to work with Gatsby's GraphQL queries. It generates multiple sizes and resolutions of each image so you don't load large images on a mobile device. So let's create GlobalStyle.js file in /components directory and move there all global styles. Note that GlobalStyle was generated by using helper function called createGlobalStyle. Normally, styled components are automatically scoped to a local CSS class and therefore isolated from other components. In the case of createGlobalStyle, this limitation is removed and things like CSS resets, or base stylesheets can be applied.
After running all three of these npm commands, the gatsby develop command resulted in an error "cannot resolve react-is in node_modules". Ran npm i react-is and the development server spun up without issue. GraphQL is an API that accesses a datastore— in this case Gatsby itself.
If the error is describing an Unknown field 'X' on type 'Query', the content type you are trying to source is likely not processing correctly. The Query type represents the top-level root queries that are included in the GraphQL schema. A common problem that trips up users that install and begin to use styled-components or emotion is not including the related plugin in the config. If we update our content with SSG, we need to rebuild our project in most cases.
The most common approach is torebuildthe page whenever wepublish. You can do that by adding deploy hooks toGatsby Cloud,netlify, orvercel, for example. You can find out how to generate apublishwebhook in Storyblok inthis tutorial.
You can follow theGatsby.js guidesto set up your deployment on your hosting provider. Or we have a hands-on blog post tutorial for Gatsby Cloud option. Keep in mind that by default, the Gatsby.js source plugin is loading content at build time because Gatsby serves pages with SSG by default. So, whenever you change the content inside Storyblok with Gatsby's SSG, you will need to restart your server or use therefresh datafeature described above. Readthis articleto understand the difference between build and client time in Gatsby. This would point to it being something on my system.
I have deleted the node modules folders in the workspaces and the root workspace folder and done a fresh yarn command. I also deleted the yarn.lock and package.lock files...not sure if this would cause problems. Notice that we've disabled the prop-types validation. In React, prop-types can be used to validate the properties submitted to your components. Unlike TypeScript, which is used during development, prop-type validation is used at runtime. There are some cases where this distinction can be extremely helpful, but I generally find TypeScript's type checking sufficient for my Gatsby sites.
If you would like to generate runtime prop-types when building your Gatsby site, check out gatsby-plugin-babel-plugin-typescript-to-proptypes . This command navigates to your newly created plugin folder and then uses npm init to initialize a new package. The -y flag skips some questions that are irrelevant to this project and fills in the package.json file with the minimum required values. In the first code example, the image field was not transformed by a plugin to add subfields, so it would only return a string.
With Gatsby's File System Route API, we don't have to configure gatsby-node.js file anymore, and no need to create template files. Let's import dynamic components and load JS Bridge as well as JS Client in pages/.js file. At work we have a number of front-end projects that are worked on by different project teams.
Each of these projects are designed by our internal designer and had a lot common with them . Up until now, we had no shared style-sheets or components. Components across projects were created from scratch, rewritten or copy pasted over each time. I saw a real need for an internal component library. This component library would enable teams to pull down an NPM package, import components, provide some props and have their components ready to use. Regarding typography, first I think about creating a component for each style of text and import it as needed.
However, not every text style has the same HTML tag. Preparing several of the same text styles with other tags don't seem to be the best solution. Fortunately, Dynamic Component allows you to apply any HTML element to component. To create Typography, use Styled System – responsive, theme-based style props for building design systems with React.
Styled System works with Styled Component and the most other css-in-js libraries. For some, the design and presentation of a website is the most important aspect. There are a lot of options when theming a Gatsby site (a giant inlined CSS stylesheet isn't necessarily ideal). For example, we could split our CSS into modules, rely only on locally styled components, or fully support Gatsby themes. The mystery deepens, because I've deleted the package-lock.json and node_modules folder once more before running npm i and the error persists. I have no idea how this module is still lingering around.
Doing a search for extract-text-webpack-plugin reveals no results in the repo . So far, all of the previous steps have been focused on creating internal Gatsby nodes, including the last step of verifying their creation and ability to be retrieved. However, these nodes are only visible to code running in your Gatsby project, not to visitors of your site or application.
In this step, you will add a React page template file and wire it up to your nodes so that your source plugin content turns into actual public-facing webpages. This error happens whether or not I place gatsby-plugin-styled-components into the gatsby-config.js. For some plugins like emotion, styled-components, or Sass, it won't be enough to only install the plugin, you also need to install libraries they rely on. After deleting my package-lock.json, node_modules and installing using yarn I had another error about terser-webpack-plugin cannot call minify of undefined .
I just cloned a starter github branch here and install all node modules. I searched on the web for this error but did not find any helpful info. Now you are ready to start creating Styled Components. Having just been taught React, I wanted to stick with building my website using the skills I had just learned.
To use, yarn add gatsby-transformer-remark gatsby-remark-prismjs prismjs. This installs all the required modules, including the official PrismJS library. For customization options and how to use, visit their page.
We will also configure react and react-dom as Peer Dependencies. Having them as peer dependencies will mean that once our library is installed in another project, they won't be automatically installed as dependencies. Instead, NPM will provide soft assertion by outputting a warning if a matching version of the dependencies haven't been installed alongside our component library.
To create a Gatsby site, you'll need to install the Gatsby CLI. This tool gets you up and running with a Gatsby app in no time. It also runs a development server and builds your Gatsby application for production. In the code above, you can see that we are building our library with both CommonJS and ES modules. This will allow our component to have more compatibility in projects with different JavaScript versions.
ES modules allows us to use named exports, better static analysis, tree shaking, and browser support. Now you should config gatsby-config.js to include the newly added packages. Remember to add gatsby-remark-images to gatsby-plugin-mdx as both a gatsbyRemarkPlugins option and as a plugins option. Gatsby browser and a Gatsby SSR both have wrapRootElement available to them and that is as high up the tree as you can get. To get the component set up, create a Dump.js file in your src\components folder and copypasta the code from the linked GitHub page. Custom MDX components that will receive styles from the theme can be included by adding a src/gatsby-plugin-theme-ui/components.js module.
Yarn add gatsby-plugin-styled-components styled-components babel-plugin-styled-components does not produce the error. Before I added this parameter, Both gatsby develop and gatsby build --prefix-paths worked correctly. Now I am seeing 404 errors trying to load icons in both development and when running the site after a build.
Try closing your editor, delete .cache, public, node_modules, and package-lock.json. I fixed the issue by deleting my package-lock.json file and run npm install. The new generated package-lock.json file had lot of differences. This creates the gatsby-config.js at the root of the project so I can start configuring Gatsby to read the .mdx files I created earlier.
MDX files can be imported in Node by using @mdx-js/node-loader or alternatively they can be required with the legacy package @mdx-js/register. Theme UI is a React-specific library that requires using context to access its effective components. You can optionally install and configure @mdx-js/react, which allows for context based component passing. Emotion is supported when options.jsxImportSource is set to '@emotion/react'. Install and configure the esbuild plugin @mdx-js/esbuild. This plugin has an additional option allowDangerousRemoteMdx.
Configure your JSX runtime depending on which one you use (React, Preact, Vue, etc.). This will install your local instance of the component library as a dependency to harvey-test-app! This establishes a symlink from the component library to the dependency in the consuming project. Anytime an update is made to the library, it will immediately be reflected in the consuming project. Anytime you want to update your library, you will have to increment the version in package.json following the Semantic Versioning guide.
For example, if I had a "patch" update, I'd change the version from 1.0.0 to 1.0.1 and run npm publish. Create a gatsby-node.js in the root directory of your project and add code to create a static page for each blog. In this tutorial, I'll show you how to use Gatsby to create a blog that integrates with Netlify CMS for content.
The app you build will support authoring posts in Markdown and adding/editing posts from your browser or via Git! Finally, I'll show you how to secure a section of your app with Okta. First, we require the fs, and resolve the function of the path module.
We then use the GraphQL helper to pull the comments that we stored earlier, to avoid extra HTTP requests. We remove the Markdown files that we created using the GraphQL helper. And then we check whether the comment path is not missing from the public path, so that we can create it before proceeding. There are two types of Gatsby plugins, local and external.
Local plugins are developed in a Gatsby project directory, under the /plugins directory. External plugins are those available through npm or Yarn. Also, they may be on the same computer but linked using the yarn link or npm link command in a Gatsby website project. Navigate to the gatsby-config.js and set up a source-filesystem plugin so that your images are available in image queries. GatsbyJS is a static-site generator which helps you build blazing fast websites and apps.
To front-end side, I will use Styled Components – the library which allows writing CSS styled in JS. You will also learn about Storybook for React – UI development environment that you can use to visualize different states of your UI components. It would be great if as the data shape evolves on the data source side, you could create test pages or pieces of content that are fully filled out, meaning no empty fields. Now to add the slightest of styles for some alignment for src/components/Layout.js, create an AppStyles styled component and make it the main wrapper of your Layout.
Now that we have the configuration of the site we'll need to setup the structure. By default, the Gatsby quick start created a usable site. This is super-helpful, but all of it is written in plain JavaScript and we want to use TypeScript so we'll be replacing the files that were generated.
While we're at it, we'll add some additional features. You have now configured Gatsby to load your custom source plugin, as well as told it exactly where to find the source code it should execute. In the next step, you will build out this source code to pull data into the Node.js runtime from your custom remote source. One of the core objectives of Gatsby is to solve this problem for developers, and source plugins are the main way it does so. A source plugin is a bundle of code that handles bringing data into the Gatsby ecosystem from a given source.
