{shinyValidator} aims at automating the audit of a Shiny App project's quality, particularly required during a validation/qualification process. There are many different tools available to validate Shiny apps but, to the best of our knowledge, nothing has been made to get a global overview in a centralized report.
By default, {shinyValidator}:
- Lints the code to ensure consistency and quality.
- Runs a
devtools::check()to assess package quality. - Checks whether the Shiny app starts and is alive after heavy usage (requires headless browser solutions like
{shinytest2}). - Performs output comparison between commits (plot, htmlwidget).
- Launches a load test to measure app performance and identify bottlenecks (user concurrency, ...) with
{shinyloadtest}. - Records an overall code profiling with
{profvis}. - Audits reactivity with
{reactlog}. - Provides overview of project structure with
{flow}. - Review all package dependencies against a locked environment (if provided) and show if versions are compliant.
Another goal of {shinyValidator} is to promote testing and automation (CI/CD) to deliver better Shiny apps in production.
- It must be run within a package Shiny app project, compatible with
{golem}. - It requires to control R package dependencies with
{renv}.
