Applications

An Application is simply a Julia package that includes a scripts acting as an entrypoint when launched. Such applications have a wide range of applications: recurrent analytics workflows, report generation, running a website, an interactive dashboard...

Getting started

Once you have a bin/main.jl script in the repo, you can add it as an Application that's available for you to launch in the cloud on JuliaHub.

To register an application, go to Compute > Applications on JuliaHub and click on the Add an application button to enter the app's URL (for this tutorial: https://github.com/JuliaComputing/JuliaHubVSCodeExtensionTutorial.jl).

Once completed, a new app will be added under the My Applications section:

Click on the Launch button to open a menu for configuring the compute resources as well as app specific options.

Inputs

JuliaHub supports passing parameters to an application through the global ENV dictionary. These parameters are passed as strings; simply parse them as appropriate and use them in your application's bin/main.jl script. A handy idiom is found in tutorial's exemplar main.jl:

n = parse(Int, get(ENV, "n", "1_000_000_000")) # Where 1_000_000_000 is the default value

These parameters may be entered (or not) through the web interface.
