Write a deployable Plumber file for a vetiver model — vetiver_write

Use vetiver_write_plumber() to create a plumber.R file for a vetiver_model() that has been versioned and stored via vetiver_pin_write().

Usage

vetiver_write_plumber(
  board,
  name,
  version = NULL,
  ...,
  file = "plumber.R",
  rsconnect = TRUE
)

Arguments

board: A pin board, created by board_folder(), board_connect(), board_url() or another board_ function.
name: Pin name.
version: Retrieve a specific version of a pin. Use pin_versions() to find out which versions are available and when they were created.
...: Other arguments passed to vetiver_api() such as the endpoint path or prediction type.
file: A path to write the Plumber file. Defaults to plumber.R in the working directory. See plumber::plumb() for naming precedence rules.
rsconnect: Create a Plumber file with features needed for Posit Connect? Defaults to TRUE.

Value

The content of the plumber.R file, invisibly.

Details

By default, this function will find and use the latest version of your vetiver model; the model API (when deployed) will be linked to that specific version. You can override this default behavior by choosing a specific version.

Examples

library(pins)
tmp <- tempfile()
b <- board_temp(versioned = TRUE)
cars_lm <- lm(mpg ~ ., data = mtcars)
v <- vetiver_model(cars_lm, "cars_linear")
vetiver_pin_write(b, v)
#> Creating new version '20231116T230229Z-100cb'
#> Writing to pin 'cars_linear'

vetiver_write_plumber(b, "cars_linear", file = tmp)
