An example of running webR under node.

Example of running webR under node

This repo contains an example of importing and running webR under node. The webr npm package contains both CommonJS and ES Module versions of the webR JavaScript loader, and so the following two examples are included,

• index.js loads the CommonJS build of webR using the require() function.
• index.mjs loads ES Module build of webR using import statement.

Running the example (Linux/macOS)

• Clone this repo and cd into the new directory.
• Install webR: npm install, or npm install webr.
• Run the examples: node index.js, node index.mjs, or npx tsx index.mts.

If successful, the example will load webR and display 10 normally distributed random numbers,

$ node index.mjs
