F#eXchange Presentation

This is the project hosting my F#eXchange 2018 presentation files and projects

How does it work?

It's a simple canvas based presentation.

• One canvas is used to draw the background animation
• whereas the texts are displayed on another canvas positionned on top of the first (please check index.html to see css style)

Feel free to read and hack the source code. It's easy to read and well documented (hopefully).

Underlying tech stack:

• Fable (obviously 😉)
• Elmish
• noisejs

Build requirements

• dotnet SDK 2.0 or higher
• node.js 6.11 or higher
• A JS package manager: yarn or npm

npm comes bundled with node.js, but we recommend to use at least npm 5. If you have npm installed, you can upgrade it by running npm install -g npm.

Although is not a Fable requirement, on macOS and Linux you'll need Mono for other F# tooling like Paket or editor support.

Building and running the app

In the commands below, yarn is the tool of choice. If you want to use npm, just replace yarn by npm in the commands.

• Install JS dependencies: yarn install
• Move to src folder: cd src
• Install F# dependencies: dotnet restore
• Start Fable daemon and Webpack dev server: dotnet fable yarn-start
• In your browser, open: http://localhost:8080/

Paket

Paket is the package manager used for F# dependencies. It doesn't need a global installation, the binary is included in the .paket folder. Other Paket related files are:

• paket.dependencies: contains all the dependencies in the repository.
• paket.references: there should be one such a file next to each .fsproj file.
• paket.lock: automatically generated, but should be committed to source control, see why.
• Nuget.Config: prevents conflicts with Paket in machines with some Nuget configuration.

Paket dependencies will be installed in the packages directory. See Paket website for more info.

yarn/npm

• package.json: contains the JS dependencies together with other info, like development scripts.
• yarn.lock: is the lock file created by yarn.
• package-lock.json: is the lock file understood by npm 5, if you use it instead of yarn.

JS dependencies will be installed in node_modules. See yarn and/or npm websites for more info.

Webpack

Webpack is a bundler, which links different JS sources into a single file making deployment much easier. It also offers other features, like a static dev server that can automatically refresh the browser upon changes in your code or a minifier for production release. Fable interacts with Webpack through the fable-loader.

• webpack.config.js: is the configuration file for Webpack. It allows you to set many things: like the path of the bundle, the port for the development server or Babel options. See Webpack website for more info.
