spidyr

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.

Load a webR library (downloaded with webrcli)

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

Add an index.js with:

`javascript
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)

`javascript
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.

`javascript
// All
await shareEnv()

// One
await shareEnv(
"PWD"
)
