Use vcr in vignettes

setup_knitr() registers a knitr hook to make it easy to use vcr inside a vignette. First call setup_knitr() in your setup chunk (or other chunk early in the document):

```{r setup}
#| include: false
vcr::setup_knitr()
```

Then, in a chunk where you want to use a cassette, set the cassette chunk option to the name of the cassette:

```{r}
#| cassette: name
req <- httr2::request("http://r-project.org")
resp <- httr2::req_perform(req)
```

Usage

setup_knitr(prefix = NULL, dir = "_vcr", ...)

Arguments

prefix

An prefix for the cassette name to make cassettes unique across vignettes. Defaults to the file name (without extension) of the currently executing vignette.

dir

Directory where to create the cassette file. Default: `"_vcr"“.

...

Other arguments passed on to insert_cassette().
