gatsby-starter-typescript-seo-grand 🌟

An opinionated starter library for creating React applications with Gatsby (v2) and TypeScript along with good SEO and PWA support.

View Demo

This starter library is pre-configured with the following integrations:

• TypeScript for type-safe code.
• Styled-Components for all your styles.
• modern-css-reset for a reset of sensible default styles.
• gatsby-image and gatsby-transformer-sharp for optimized images.
• gatsby-plugin-manifest / SEO component for an SEO-friendly PWA.
• Jest and React Testing library for snapshots and unit tests.
• gatsby-plugin-catch-links for avoiding the browser having to refresh the whole page when navigating between local pages.
• ESLint with an emphasis on functional patterns (with Prettier and TypeScript integration) to make your code look its best.
• React Axe and React A11y for accessibility so that your site is awesome for everyone.

Installation

You will need to have node and npm installed on your computer.

You can either use npx or install the gatsby-cli globally.

The npx way:

npx gatsby new my-site https://github.com/S-ayanide/gatsby-starter-typescript-seo-grand

or the global way:

npm i -g gatsby-cli
gatsby new my-site https://github.com/S-ayanide/gatsby-starter-typescript-seo-grand

Usage

To start the development servers:

npm run develop

If all was successful, you should see links to two development servers in the Node terminal. You can open these url in any browser that you would like.

1. http://localhost:8080:

This is the development server that allows you to preview your website. It comes with hot-module reloading, which means that you should see your changes almost immediately without having to refresh the browser tab.

2. http://localhost:8000/___graphql:

This is the development server that allows you to interact with the your site's GraphQL data via the GraphiQL IDE.

Available Scripts

Styling

This library is pre-configured with styled-components.

Global Styles

Global styles are defined in the src/styles/global.css file.

The global style also includes the styles from css-modern-reset, which aims to provide a sensible reset of browser styles.

Theme

You can define your theme styles in the /src/styles/theme file. The theme will be available in any styled-component via props.theme and to any other component via the useTheme hook.

Handling Media Queries

The theme utilizes the use-media library, which allows you to track the state of a CSS media queries. This works by passing a boolean for each screen size that you defined in your theme. Just define your screen sizes in src/styles/theme.

The CSS Prop

This starter is also preconfigured to work with the css prop:

import styled from "styled-components";

const MyComponent = () => (
	<div>
		<h1
			css={`
				color: #333;
			`}
		>
			Hello World!
		</h1>
	</div>
);

Note: The css prop does not play nicely with the jsx-no-multiline-js ESLint rule. You may want to disable the rule if you plan on using the css prop. This can be done in the .eslintrc.js file.

I personally do not use the css prop and prefer to define styled-components outside of the component definition. My general rule is if the component that is using a styled-component is the only component that uses it, I define the styled-component in the same file. Otherwise, I will move it out to a components/common directory.

import styled from "styled-components";

const Heading = styled.h1`
	color: #333;
`;

const MyComponent = () => (
	<div>
		<Heading>Hello World!</Heading>
	</div>
);

Preview

Linting

This project includes a combination of ESLint and React-A11y rules for React and TypeScript code, which are extended from the eslint-config-gojutin npm package. Many of the rules favor a functional approach with a strong emphasis on immutability and strong type definitions. Since all of the rules and dependencies are included in this package, you can easily remove it if you prefer to wire up your own linting configuration.

The rules are listed as key/value pairs. The key represents the rule name and the value (number) represents the setting of the rule:

0	off
1	warn
2	error

Here is an example of a rule:

"immutable/no-this": 2

This particular rule disallows the use of the this keyword, which will result in an error.

Deployment

Lint your files and fix all linting issues.

npm run lint

Run your test suite and fix any broken tests.

npm run test

Compile a production build to the /public directory.

npm run build

Lighthouse Audit Score 💯

TODOS

• Write more robust unit tests for all components and custom hook.
• Possibly add support for MDX and markdown.

That's about it. Now, build something awesome 😀
