This self-study repository is designed to allow you to experience the SAFE stack based on a ready-made application that you can build on top of. It will take around 90 minutes for you to complete if you have no experience in any of these technologies.

The master branch contains the dojo to complete. Please read the for a guide on completing this dojo, to learn all about the SAFE Stack and F#. There is a "completed" version in the suggested-solution branch.

Install pre-requisites

You'll need to install the following pre-requisites in order to build SAFE applications

Starting the application

Before you run the project for the first time only you must install dotnet "local tools" with this command:

Open the editor:

code .

Build and run in watch mode using the following command:

dotnet run

NOTE: You may have to allow dotnet or Server access to your public and/or private network.

Then open http://localhost:8080 in your browser. Arrange the windows so you can see both Code editor and the web browser.

Completing the tasks

Search files (Ctrl+Shift+F or Edit --> Find in Files) and search through for "Task 1" to start completing the Dojo.

Going further: bundling your app

There is Bundle to package your app:

dotnet run -- Bundle

Going further: deploying to Azure
