Hackers at Cambridge Website

The public website of [Hackers at Cambridge]()

This website is built using the Swift web framework Kitura. This allows us to build the site fast and reliably and to learn about and contribute to server-side Swift in the process.

For more reasons as to why we chose to do things this way, please read our blog post about it.

Installing and running the website

Docker

We use Docker to make installation quick and painless, make sure you have it installed. This has been tested to work with at least docker 17.03.0-ce, build 60ccb22 and docker-compose version 1.11.2, build dfed245.

If you are on GNU/Linux, you will also need to install Docker Compose seperately

If you are on Windows, go to Docker settings and ensure the drive you are using is shared.

Installation Instructions

• Clone this repository: git clone https://github.com/hackersatcambridge/hac-website.git
• Navigate to the hac-website directory that you've now cloned
• Now run docker-compose up

This will build the project run the web server at localhost:3000. It will also watch for changes to the files and rebuild as necessarily. You can stop this process at any time with ^C (ctrl + C).

Subsequent runs

When you want to run the project again (and you will, it's great):

• If the Dockerfile has been changed, run docker-compose build
• run docker-compose up

Notes on using Windows

If you are on Windows, go to Docker settings and ensure the drive you are using is shared.

We also use use Gulp for hot-reloading and building of the website when we make edits during development, however as inotify doesn't work on shared drives, hot-reloading doesn't work out of the box.

There is an alternative solution available, which essentially requires the following.

Run pip install docker-windows-volume-watcher, then, after you have done docker-compose up, open another console window and run docker-volume-watcher.

Development

Contributing

Please look at the CONTRIBUTING.md on how to contribute to the project!

"Um. It looks like your HTML is written in Swift."

You may notice that we aren't using a templating library for rendering HTML. Inspired by the likes of Elm and React, we've written a module HaCTML for making HTML type-safe and Swifty! For an example, have a look at our home page.

We're currently experimenting with the API for HaCTML, and once it's a little more stable we hope to release it as a standalone module.

Unit Testing

In order to run unit tests:

docker-compose run web yarn test

Working with the Docker container

What docker-compose up is doing

This command starts up a docker container that has all the required dependencies, then starts up a development server.

Internally, this command uses the Gulp task runner*. Check out our Gulpfile to see everything that does.

TL;DR

• Builds the Swift files
• Builds the stylesheets
• Starts the server (at localhost:3000)
• Waits eagerly for you to make changes to any of the files, rebuilds, and reloads the browser (powered by BrowserSync)

*It is worth noting that we are using Gulp v4, which hasn't been officially released. It would be useful to refer to the version 4 documentation.

Running commands in the container

If you want to access an instance of yarn or swift inside the Docker container to do some debugging or modifications, you can simply use docker-compose run.

docker-compose run web swift <<SWIFT COMMAND>>
docker-compose run web yarn <<YARN COMMAND>>
docker-compose run web yarn gulp <<GULP COMMAND>>

As the container shares source files with your project directory, any source files modified inside the container (e.g. package.json) will also be modified outside the container (and vice versa).

Documentation

Documentation on further features can be found in the /Docs folder.
