gatsby-theme-apollo-core
This is the base theme for building Apollo-branded Gatsby sites. It contains a small amount of configuration, and a handful of components that make it easy to build consistent-looking UIs.
It comes with a few Gatsby plugins:
gatsby-plugin-svgr
enables importing SVGs as React componentsgatsby-plugin-emotion
server renders your Emotion stylesgatsby-plugin-react-helmet
server renders<head>
tags set with React Helmetgatsby-plugin-typography
provides a stylesheet reset and sets default styles for basic HTML elements
Installation
$ npm install gatsby gatsby-theme-apollo-core
Configuration
// gatsby-config.js
module.exports = {
plugins: ['gatsby-theme-apollo-core'],
siteMetadata: {
title: 'Apollo rocks!',
description: 'Gatsby themes are pretty cool too...'
}
};
Components and utilities
All of the React components and utilities documented here are available as named exports in the gatsby-theme-apollo-core
package. You can import them like this:
import {MenuButton, Sidebar, breakpoints} from 'gatsby-theme-apollo-core';
Layout
Layout
should wrap every page that gets created. It configures React Helmet and sets the meta description tag with data from the siteMetadata
property in your Gatsby config.
import {Layout} from 'gatsby-theme-apollo-core';
function MyPage() {
return (
<Layout>
Hello world
</Layout>
);
}
| Prop name | Type | Required | | --------- | ---- | -------- | | children | node | yes |
Sidebar
A component that renders a sidebar with a LogoTitle
component in the top left corner. It can also be configured to collapse into the left side of the page on narrow windows.
import {Layout, Sidebar} from 'gatbsy-theme-apollo';
function MyPage() {
return (
<Layout>
<Sidebar>
Sidebar content goes here
</Sidebar>
</Layout>
);
}
| Prop name | Type | Required | Description |
| ---------- | ------ | -------- | -------------------------------------------------------------------------------- |
| children | node | yes | |
| responsive | bool | no | If true
, the sidebar will behave as a drawer absolutely positioned on the left |
| open | bool | no | Controls the sidebar visibility when the responsive
prop is true
|
| logoLink | string | no | The URL/path that the sidebar logo should link to |
SidebarNav
A configurable two-tiered, expandable/collapsible navigation component for use in conjunction with the Sidebar
component above. It accepts a contents
prop that defines what links and collapsible sections get rendered. Here's an example of the expected shape of a contents
prop:
const contents = [
{
title: 'Getting started',
path: '/'
},
{
title: 'External link',
path: 'https://apollographql.com',
anchor: true
},
{
title: 'Advanced features',
pages: [
{
title: 'Schema stitching',
path: '/advanced/schema-stitching'
}
]
}
];
Each element in the array can have title
, path
, pages
, and anchor
props. pages
is an array of more elements with the same shape. By default, a Gatsby Link
component will be used to render the links, but you can use a regular HTML anchor tag (<a>
) by passing the anchor
property to true
on any page object.
The SidebarNav
component gives the currently selected page an "active" style, and if it's a subpage, it will keep the currently active section expanded. To facilitate this, you must pass the current path to the pathname
prop. Luckily, Gatsby exposes this in the location
prop that gets passed automatically to every page!
import {Layout, Sidebar, SidebarNav} from 'gatsby-theme-apollo-core';
function MyPage(props) {
return (
<Layout>
<Sidebar>
<SidebarNav
contents={contents}
pathname={props.location.pathname}
/>
</Sidebar>
</Layout>
);
}
| Prop name | Type | Required | Description |
| -------------- | ------ | -------- | ----------------------------------------------------------------- |
| contents | array | yes | An array of items to render |
| pathname | string | yes | The current path (props.location.pathname
expected) |
| alwaysExpanded | bool | no | If true
, all collapsible sections are expanded and cannot close |
ResponsiveSidebar
A render props component that manages the state for responsive sidebars. On mobile devices, the sidebar is opened by a MenuButton
component, and dismissed when the user clicks away from the sidebar. This component's children
prop accepts a function that provides values and functions to enable this behavior easily.
import {
Layout,
Sidebar,
ResponsiveSidebar,
FlexWrapper,
MenuButton
} from 'gatsby-theme-apollo-core';
function MyPage() {
return (
<Layout>
<ResponsiveSidebar>
{({sidebarOpen, openSidebar, onWrapperClick, sidebarRef}) => (
<FlexWrapper onClick={onWrapperClick}>
<Sidebar responsive open={sidebarOpen} ref={sidebarRef}>
This is a sidebar
</Sidebar>
<MenuButton onClick={openSidebar} />
</FlexWrapper>
)}
</ResponsiveSidebar>
</Layout>
);
}
| Prop name | Type | Required | Description | | --------- | ---- | -------- | ----------------------------------------------------------- | | children | func | yes | A render prop-style function that returns a React component |
Logo
A component that renders the Apollo logo. This logo can be removed or replaced using component shadowing.
import {Logo} from 'gatsby-theme-apollo-core';
function MyPage() {
return <Logo />;
}
Customizing the logo
Through component shadowing, you can override the logo that gets shown. Simply create a file that exports a SVG React component in your theme consumer at src/gatsby-theme-apollo-core/components/logo.js.
// src/gatsby-theme-apollo-core/components/logo.js
export {ReactComponent as default} from '../../assets/custom-logo.svg';
Check out this CodeSandbox link for a full component shadowing example.
| Prop name | Type | Required | Description |
| --------- | ---- | -------- | ------------------------------------ |
| noLogo | bool | no | If true
, the Apollo logo is hidden |
Colors
An object mapping semantic names to hex strings. All of these colors are drawn from Space Kit. You can use this utility to write CSS-in-JS rules like this:
import {colors} from 'gatsby-theme-apollo-core';
const StyledButton = styled.button({
color: colors.primary,
background: colors.background
});
Customizing colors
You can override the default color palette using shadowing. The only constraint is that the primary
and secondary
palette keys must be colors from Space Kit. Here's an example of a shadowed color palette:
// src/gatsby-theme-apollo-core/utils/colors.js
const {colors} = require('gatsby-theme-apollo-core/src/utils/colors');
const {colors: spaceKitColors} = require('@apollo/space-kit/colors');
exports.colors = {
...colors,
primary: spaceKitColors.red.base,
divider: '#aeaeae'
};
You can refer to the default colors file for palette keys that can be customized.
Breakpoints
A mapping of size keys to media queries. This is useful for writing responsive CSS-in-JS components.
import {breakpoints} from 'gatsby-theme-apollo-core';
const StyledMenu = styled.nav({
fontSize: 24,
[breakpoints.lg]: {
fontSize: 20
},
[breakpoints.md]: {
fontSize: 16
},
[breakpoints.sm]: {
fontSize: 12
}
})
| Key | Value | | --- | -------------------------- | | sm | @media (max-width: 600px) | | md | @media (max-width: 850px) | | lg | @media (max-width: 1120px) |
Deploying to a subdirectory
In order to deploy a Gatsby site to a subdirectory, there are a few extra steps to take. First, you must provide a pathPrefix
property in your Gatsby config. This option combined with the --prefix-paths
option in the Gatsby CLI will handle most of the hard work. Read more about path prefixing in Gatsby here.
// gatsby-config.js
module.exports = {
...
pathPrefix: '/YOUR_PATH_PREFIX'
};
Now, when you run npx gatsby bulid --prefix-paths
, all pages, references to static assets, and links between pages will be prefixed with your custom path. That means that if you made a page with the path /about, it will live at /YOUR_PATH_PREFIX/about. In order for this to work within our server configuration, your website files also must exist in a directory with the same name. Here's how this sequence of events would look if you ran commands in your terminal:
$ npx gatsby build --prefix-paths
$ mkdir -p YOUR_PATH_PREFIX
$ mv public/* YOUR_PATH_PREFIX
$ mv YOUR_PATH_PREFIX public/
We use Netlify to deploy our websites, so to express this slightly more complicated build process to them, create a netlify.toml file that follows this pattern:
# netlify.toml
[build]
base = "/"
publish = "public/"
command = "gatsby build --prefix-paths && mkdir -p YOUR_PATH_PREFIX && mv public/* YOUR_PATH_PREFIX && mv YOUR_PATH_PREFIX public/"
We use Fly to manage our server rewrites and redirects. To point your new Netlify deployment to a page on apollographql.com, first create a new backend using your site's Netlify alias. Next, you'll need to add two rewrite rules:
/YOUR_PATH_PREFIX/:page
➡️/YOUR_PATH_PREFIX/$page
/YOUR_PATH_PREFIX
➡️/YOUR_PATH_PREFIX
Be sure to set the priority of each of these rules to 3
, or a value lower than the top two redirect rules that apply to our website root. Once these rewrite rules take effect, your site will be live at https://apollographql.com/YOUR_PATH_PREFIX.
