spidyr

[Work in Progress] Please consider the API unstable until v1.0.0 is reached.

Tools for extending webR in NodeJS.

Note that spidyr is designed to work with webrcli.

https://github.com/ColinFay/webrcli

Load a webR library (downloaded with webrcli)

mkdir spongebob
cd spongebob
npm init -y
npm install webr spidyr
webrcli install spongebob

Add an index.js with:

const { initSpidyr, library } = require('spidyr');

(async () => {

  await initSpidyr()

  const spongebob = await library("spongebob")

  const said = await spongebob.tospongebob("Hello world")

  console.log(said.values)
})();

To load from a local folder containing an R package

Provided you have your funs in ./rfuns (default after webrcli init)

const { initSpidyr, mountLocalPackage } = require('spidyr');

(async () => {

  await initSpidyr()

  const rfuns = await mountLocalPackage("./rfuns");

  const hw = await rfuns.hello_world()

  console.log(hw.values);
})();

Tools

The shareEnv function allows to copy one, severals, or all environment variables from the Node process to webR.

// All
await shareEnv()

// One
await shareEnv(
 "PWD"
)
