cypress-rollup-preprocessor

Installation

First install node.js. Then:

npm install cypress-rollup-preprocessor --save

It is likely you already have these installed either directly or as a transient dependency, but if not, you will need to install them.

npm install --save-dev rollup

Compatibility

This version is only compatible with rollup 2.x+

Usage

In your project's plugins file:

const rollupPreprocessor = require("cypress-rollup-preprocessor");
module.exports = (on) => {
  on("file:preprocessor", rollupPreprocessor());
};

Options

Pass in options as the argument to rollup:

const rollupPreprocessor = require("cypress-rollup-preprocessor");

module.exports = (on) => {
  const options = {
    // send in the options from your rollup.config.js, so it works the same
    // as your app's code
    rollupOptions: require("../../rollup.config"),
  };

  on("file:preprocessor", rollupPreprocessor(options));
};

rollupOptions

Object of rollup options. Just require in the options from your rollup.config.js to use the same options as your app.
