Features

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

Despite being built with React, and despite all the project images making it a very image-heavy portfolio, Gatsby makes the final site super fast. So fast, it's almost unreal and feels like magic. And makes it work without JavaScript by server-side rendering all routes. And so much more.

One data file to rule all pages

All content is powered by one YAML file, data/projects.yml where all the portfolio's projects are defined. The project description itself is transformed from Markdown.

Gatsby automatically creates pages from each item in that file utilizing the src/templates/Project.jsx template.

Theme switcher

Includes a theme switcher which allows user to toggle between a light and a dark theme. Switching between them also happens automatically based on time of day.

If you want to know how, have a look at the respective component under src/components/molecules/ThemeSwitch.jsx

SEO component

Includes a SEO component which automatically switches all required meta tags for search engines, Twitter Cards, and Facebook OpenGraph tags based on the browsed route/page.

If you want to know how, have a look at the respective component under src/components/atoms/SEO.jsx

Client-side vCard creation

The Add to addressbook link in the footer automatically creates a downloadable vCard file on the client-side, based on data defined in data/meta.yml.

If you want to know how, have a look at the respective component under src/components/atoms/Vcard.jsx

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, gatsby-plugin-matomo, which is in use on this site.

Project images

All project images live under src/images and are automatically attached to each project based on the inclusion of the project's slug in their filenames.

(TODO: automatically add the inital image to each project node, so it doesn't have to be defined in the projects.yml file.)

All project images make use of the excellent gatsby-image plugin, working in tandem with gatsby-plugin-sharp and gatsby-transformer-sharp.

All together, Gatsby automatically generates all required image sizes for delivering responsible, responsive images to visitors, including lazy loading of all images. Also includes the intersection-observer polyfill to make lazy loading work properly in Safari.

All project images use one single component defined in src/components/atoms/ProjectImage.jsx. In there, one main GraphQL query fragment is defined, which then gets used throughout other GraphQL queries.

Importing SVG assets

Makes use of gatsby-plugin-svgr so SVG assets can be imported like so:

import { ReactComponent as Logo } from '../images/logo.svg'

Development

git clone git@github.com:kremalicious/portfolio.git
cd portfolio/

npm i
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

Add a new project

To add a new project, run the following command. This adds a new item to the top of the projects.yml file, creating the title & slug from the argument:

npm run new -- "Hello"

Then continue modifying the new entry in data/projects.yml.

Finally, add as many images as needed with the file name format and put into src/images/:

portfolio-SLUG-01.png
portfolio-SLUG-02.png
portfolio-SLUG-03.png
...

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.
