+# cypress-on-fix
+
+> Fixes multiple Cypress plugins subscribing to "on" events
+
+## Install
+
+Add this NPM package as a dev dependency
+
+```
+# install using NPM
+$ npm i -D cypress-on-fix
+# install using Yarn
+$ yarn add -D cypress-on-fix
+```
+
+Wrap the `on` passed by Cypress in your config file
+
+```js
+const { defineConfig } = require('cypress')
+
+module.exports = defineConfig({
+  e2e: {
+    // baseUrl, etc
+    supportFile: false,
+    fixturesFolder: false,
+    setupNodeEvents(cypressOn, config) {
+      const on = require('.')(cypressOn)
+      // use "on" to register plugins, for example
+      // https://github.com/bahmutov/cypress-split
+      require('cypress-split')(on, config)
+      // https://github.com/bahmutov/cypress-watch-and-reload
+      require('cypress-watch-and-reload/plugins')(on, config)
+      // https://github.com/bahmutov/cypress-code-coverage
+      require('@bahmutov/cypress-code-coverage/plugin')(on, config)
+    },
+  },
+})
+```
+
+## Debugging
+
+This module uses [debug](https://github.com/debug-js/debug#readme) to print verbose log messages. Run Cypress with
+
+```
+DEBUG=cypress-on-fix npx cypress run ...
+```
