Improve dashboard loading time #55

Closed mwakok closed 1 year ago

Building and serving the dashboard locally has the same loading delay as the deployed dashboard on shinyapps. This would mean it is not tied to hardware and moving it to a VPS would not improve the loading times. Instead, I think it is linked to rendering the dashboard and loading the data. This guide provides solutions for pre-rendering the dashboard and caching the data.

some of the packages were loaded, but not used. After the analysis with funchir::stale_package_check('test.R')*, I removed some of the unused packages, which reduced the local loading tiem from 30s to 12s.

*As the function stale_package_check() accepts only .R scripts, test.R is the dccapp.Rmd file transformed to test.R.

I'll see if more improvements are feasible/ necessary.

looked at the runtime: shiny_prerendered solution, but two of the graphs do not render: (see 8e18e057a49622f40d4246d1d27595777fe80275 ).
