Generate a HTTP API wrapper package from a yaml template for the API

The internals are a little hacky, but the point is to have as few dependencies as possible, just depending on yaml right now.

Steps

  • Specify API in a YAML file
  • Run apipkgen::generate_pkg() to generate a package
  • Write wrapper functions in the new package
  • Done!

Features

  • Package generation from a yaml template
  • gives back raw text right now, will add toggles to add JSON vs. XML parsers
  • specify query parameters, including options, whether required or not, and expected class
  • same as previous, but for paths on the base URL

Example spec

Package Status and Installation

AppVeyor Build Status Travis-CI Build Status codecov rstudio mirror downloads

devtools::install_github("ropenscilabs/apipkgen")
library("apipkgen")

Simple yml template (not fitting swagger/etc.)

generate a package

use the function generate_pkg()

template <- system.file('examples', 'template_crossref.yml',
    package = "apipkgen")
path <- file.path(tempdir(), "crpkg")
generate_pkg(path, template_path = template)

your package needs functions

The package created doesn’t have any exported functions, just internal functions for your to build user facing functions.

Let’s write a user facing functions. The Crossref API template above specified for the works route that parameters are query and rows. So let’s work with those.

In addition, it’s a good idea to always allow users to pass in curl options. Beginners can ignore it, but power curl users will want/have to play with curl options. The function builder builds in ... as a parameter so in the user facing function above all you have to do is add that as well for users to access.

Install package

Go to the new directory, and in R/RStudio run devtools::document() and devtools::install() (or equivalent).

Swagger/OpenAPI

Example 1

Get a spec, in this case from the Province of British Columbia https://github.com/bcgov/api-specs

Generate the package, and install it

Restart R …

Get man page for a function

Run some functions

cleanup

unlink("bcgov", TRUE, TRUE)
unlink(bc_spec_path, TRUE)
remove.packages("bcgov")

Example 2

An example with the Directory of Open Access Journals

Generate the package, and install it

Run a function
