🎆 EXIF extraction

Automatically extracts EXIF metadata from my photos on build time. For minimal overhead, fast-exif parses every JPG file upon Gatsby file node creation and adds the extracted EXIF 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:

✨ Development

You need to have the following tools installed on your development machine before moving on:

Then install dependencies and start everything up:

npm i

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

npm start

🔮 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

👩‍🔬 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

🎈 Add a new post

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

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

🚚 Deployment

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

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

The deploy command simply calls the scripts/deploy.sh 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.
