๐Ÿญ My blog built with Gatsby + TypeScript. Neat.

๐ŸŽ‰ Features

The whole blog is a React-based Single Page App built with Gatsby v2.

๐ŸŽ† EXIF extraction

Automatically extracts EXIF & IPTC metadata from my photos on build time. For minimal overhead, fast-exif & node-iptc parse every JPG file upon Gatsby file node creation and add the extracted data as node fields.

This way, EXIF data is only extracted at build time and can be simply queried with GraphQL at run time.

In the end looks like this, including location display with pigeon-maps:

๐Ÿ’ฐ Cryptocurrency donation via Web3/MetaMask

Lets visitors say thanks with Bitcoin or Ether. Uses web3.js for sending Ether transactions via MetaMask, Brave or Mist. Component listens to account & network changes and adapts accordingly.

As a fallback, QR codes are generated with react-qr-svg from the addresses defined in config.js.

๐Ÿ” Search

A global search is provided with gatsby-plugin-lunr. That plugin creates a Lunr search index file of all posts on build time which is then queried against when the search field is used.

๐Ÿ“ GitHub changelog rendering

Adds ability to show contents of a changelog, rendered from a on GitHub from the given repository. The use case is to enhance release posts about projects hosted on GitHub. Makes use of the GitHub GraphQL API via gatsby-source-graphql.

Adding this to a post's YAML frontmatter:

changelog: gatsby-plugin-matomo

will render this at the end of the post:

๐Ÿ“ˆ Matomo (formerly Piwik) analytics tracking

Site sends usage statistics to my own Matomo installation. To make this work in Gatsby, I created and open sourced a plugin which is in use on this site.


๐Ÿ’Ž Importing SVG assets

All SVG assets under src/images/ will be converted to React components with the help of gatsby-plugin-svgr. Makes use of SVGR so SVG assets can be imported like so:

import { ReactComponent as Logo } from './components/svg/Logo'
;<Logo />

๐Ÿฌ Typekit component

Includes a component for adding the Typekit snippet.

โœจ Development

You can simply use Docker & Docker Compose or install and run dependencies on your local system.

git clone
cd blog/

# GATSBY_GITHUB_TOKEN is required for some parts
cp .env.sample .env
vi .env

# use Docker
docker-compose up

# or go with local system
npm i
npm start

๐Ÿ”ฎ Linting

ESlint, Prettier, and Stylelint are setup for all linting purposes:

npm run lint

To automatically format all code files:

npm run format
npm run format:css

๐Ÿ‘ฉโ€๐Ÿ”ฌ Testing

Test suite is setup with Jest and react-testing-library.

To run all tests, including all linting tests:

npm test

All test files live beside the respective component. Testing setup, fixtures, and mocks can be found in ./jest.config.js and ./jest folder.

For local development, run the test watcher:

npm run test:watch

๐ŸŽˆ Add a new post

npm run new "Hello World"
npm run new "Hello World" 2017-12-27

Create a new photo post with date, title & description pre-filled from EXIF/IPTC data of a given image file:

npm run new photo /path/to/photo.jpg

๐Ÿšš Deployment

Automatic deployments are triggered upon successful tests & builds on Travis:

  • push to main initiates a live deployment
  • any Pull Request, and subsequent pushes to it, initiates a beta deployment

The deploy command simply calls the scripts/ script, syncing the contents of the public/ folder to S3:

npm run deploy

The deploymeng script can be used locally too, the branch checks are only happening for Travis builds, allowing to deploy any branch from local machine.
