Export a recipe to JSON

Serializes the recipe to a JSON string or file. All object classes are stripped for clean serialization. The JSON format includes a schema version tag ("1") and can be re-imported with recipe_import_json.

Usage

recipe_export_json(recipe, file = NULL)

Arguments

recipe

An omop_recipe object.

file

Character or NULL; file path to write. If NULL, returns the JSON string directly.

Value

If file is NULL, returns a JSON string (invisibly). Otherwise writes to file and returns the file path invisibly.

Examples

if (FALSE) { # \dontrun{
json <- recipe_export_json(recipe)
recipe_export_json(recipe, file = "my_recipe.json")
} # }
