Get or create the cache directory path

Source: R/cache.R
cache_dir.Rd

Returns the path where shinyelectron stores downloaded runtimes (R, Python, Node.js) and other cached assets. By default, the directory is created if it doesn't already exist. Pass create = FALSE to query the path without side effects.

Usage

cache_dir(create = TRUE)

Arguments

create

Logical. Whether to create the directory if it doesn't exist. Default is TRUE.

Value

Character string. Absolute path to the cache directory, typically ~/.cache/shinyelectron/assets on Linux, ~/Library/Caches/shinyelectron/assets on macOS, or \%LOCALAPPDATA\%/shinyelectron/shinyelectron/Cache/assets on Windows.

Cache Layout

Cached runtimes are organized by type, platform, architecture, and version:

assets/
|-- r/
|   |-- win/x64/4.5.3/
|   |-- mac/arm64/4.5.3/
|-- python/
|   |-- win/x64/3.12.10/
|   |-- mac/arm64/3.12.10/
|-- nodejs/
|   |-- v22.11.0/darwin-arm64/
|   |-- v22.11.0/win-x64/

Use cache_info() to see what's actually installed with disk usage.
