How to implement dynamic config files with preprocessor

[przemdabr]

I'm using cypress-cucumber-preprocessor with esbuild.
I have many test environments and I want to add dynamically proper parameters from my config files loading from scripts.
JSON config files with unique parameters are located in the cypress/config directory: test.json, test2.json, dev.json, local.json etc.
I don't want to duplicate parameters and create each cypress.config.ts file and run it by pointing to --config-file cypress/config/local.cypress.config.ts.

Is there any way to overwrite the config from setupNodeEvents ?

The example below doesn't work.

async function setupNodeEvents(
  on: Cypress.PluginEvents,
  config: Cypress.PluginConfigOptions
): Promise<Cypress.PluginConfigOptions> {
  // This is required for the preprocessor to be able to generate JSON reports after each run, and more,
  await preprocessor.addCucumberPreprocessorPlugin(on, config);
  on(
    'file:preprocessor',
    createBundler({
      plugins: [createEsbuildPlugin(config)],
    })
  );
  on('before:browser:launch', (browser, launchOptions) => {
    if (browser.family === 'chromium' && browser.name !== 'electron') {
      launchOptions.args.push('--disable-dev-shm-usage');
      launchOptions.args.push('--js-flags=--expose-gc');
    }
    if (browser.family === 'chromium' && browser.name !== 'electron' && browser.isHeaded) {
      launchOptions.args.push('--disable-dev-shm-usage');
      launchOptions.args.push('--js-flags=--expose-gc');
      // `args` is an array of all the arguments that will be passed to browsers when it launches
      console.log(launchOptions.args); // print all current browser args
      // auto open devtools on the dashboard mode
      launchOptions.args.push('--auto-open-devtools-for-tabs');
      //launchOptions.args.push('--start-fullscreen')
    }
    if (browser.family === 'firefox' && browser.isHeaded) {
      // auto open devtools
      launchOptions.args.push('-devtools');
    }
    return launchOptions;
  });
  function getConfigurationByFile(file) {
        // accept a configFile value or use dev by default
        const pathToConfigFile = path.resolve('cypress/config/', `${file}.json`)
        return fs.readJson(pathToConfigFile)
    }
    const file = config.env.configFile || 'dev';
  // Make sure to return the config object as it might have been modified by the plugin.
  return config && getConfigurationByFile(file);
}
