In Docusaurus 2, we split each functionality (blog, docs, pages) into plugins for modularity. Presets are bundles of plugins and for backward compatibility we built a `@docusaurus/preset-classic` preset which bundles most of the essential plugins present in Docusaurus 1. + +Add the following preset configuration to your `docusaurus.config.js`. + +```jsx +// docusaurus.config.js +module.exports = { + // ... + presets: [ + [ + '@docusaurus/preset-classic', + { + docs: { + // docs folder path relative to site dir. + path: '../docs', + // sidebars file relative to site dir. + sidebarPath: require.resolve('./sidebars.json'), + }, + ... + }, + ], + ], +}; +``` + +Refer to migration guide below for each field in `siteConfig.js`. + +#### `baseUrl`, `tagline`, `title`, `url`, `favicon`, `organizationName`, `projectName`, `githubHost` + +No actions needed. + +#### `colors` + +Deprecated. We wrote a custom CSS framework for Docusaurus 2 called Infima which uses CSS variables for theming. The docs are not quite ready yet and we will update here when it is. To overwrite Infima' CSS variables, create your own CSS file (e.g. `./src/css/custom.css`) and import it globally by passing it as an option to `@docusaurus/preset-classic`: + +```diff +// docusaurus.config.js +module.exports = { + // ... + presets: [ + [ + '@docusaurus/preset-classic', + { ++ theme: { ++ customCss: require.resolve('./src/css/custom.css'), ++ }, + }, + ], + ], +}; +``` + +Infima uses 7 shades of each color. We recommend using [ColorBox](https://www.colorbox.io/) to find the different shades of colors for your chosen primary color. + +```css +/** + * /src/css/custom.css + * You can override the default Infima variables here. + * Note: this is not a complete list of --ifm- variables. + */ +:root { + --ifm-color-primary: #25c2a0; + --ifm-color-primary-dark: rgb(33, 175, 144); + --ifm-color-primary-darker: rgb(31, 165, 136); + --ifm-color-primary-darkest: rgb(26, 136, 112); + --ifm-color-primary-light: rgb(70, 203, 174); + --ifm-color-primary-lighter: rgb(102, 212, 189); + --ifm-color-primary-lightest: rgb(146, 224, 208); +} +``` + +#### `footerIcon`, `copyright`, `ogImage`, `twitterImage` + +Site meta info such as assets, SEO, copyright info are now handled by themes. To customize them, use the `themeConfig` field in your `docusaurus.config.js`: + +```jsx +// docusaurus.config.js +module.exports = { + themeConfig: { + footer: { + logo: { + alt: 'Facebook Open Source Logo', + src: 'https://docusaurus.io/img/oss_logo.png', + }, + copyright: `Copyright © ${new Date().getFullYear()} Facebook, Inc.`, + }, + image: 'img/docusaurus.png', + ... + }, +}; +``` + +#### `headerIcon`, `headerLinks` + +In Docusaurus 1, header icon and header links were root fields in `siteConfig`: + +```js +headerIcon: 'img/docusaurus.svg', +headerLinks: [ + { doc: "doc1", label: "Getting Started" }, + { page: "help", label: "Help" }, + { href: "https://github.com/", label: "GitHub" }, + { blog: true, label: "Blog" }, +], +``` + +Now, these two fields are both handled by the theme: + +```jsx +// docusaurus.config.js +module.exports = { + themeConfig: { + navbar: { + title: 'Docusaurus', + logo: { + alt: 'Docusaurus Logo', + src: 'img/docusaurus.svg', + }, + links: [ + {to: 'docs/doc1', label: 'Getting Started', position: 'left'}, + {to: 'help', label: 'Help', position: 'left'}, + { + href: 'https://github.com/', + label: 'GitHub', + position: 'right', + }, + {to: 'blog', label: 'Blog', position: 'left'}, + ], + }, + ... + }, +}; +``` + +#### `algolia` + +```jsx +// docusaurus.config.js +module.exports = { + themeConfig: { + algolia: { + apiKey: '47ecd3b21be71c5822571b9f59e52544', + indexName: 'docusaurus-2', + algoliaOptions: { ... }, + }, + ... + }, +}; +``` + +#### `blogSidebarCount` + +Deprecated.
