# Resolve the current app version
|
||
|
||
Tries two strategies in order:
|
||
|
||
1. `utils::packageVersion(package_name)` – works when the package is
|
||
installed locally (development, local
|
||
[`runApp()`](https://rdrr.io/pkg/shiny/man/runApp.html)).
|
||
|
||
2. `app_version` argument – an explicit version string supplied by the
|
||
caller, e.g. from an `app_version()` function bundled with the app.
|
||
Used on shinyapps.io where the package is not installed.
|
||
|
||
## Usage
|
||
|
||
``` r
|
||
.resolve_app_version(package_name, app_version = NULL)
|
||
```
|
||
|
||
## Arguments
|
||
|
||
- package_name:
|
||
|
||
Name of the package / repository.
|
||
|
||
- app_version:
|
||
|
||
Optional fallback version string.
|
||
|
||
## Value
|
||
|
||
A character string with the version (e.g. "1.1.0"), or NULL if neither
|
||
strategy succeeds.
