How to change electron-forge default port?

In Electron Forge, changing the default port typically involves modifying the project's configuration files. Electron Forge is a popular tool for developing and building Electron applications. By default, Electron Forge may use a standard port for the development server, such as 3000 or 8080. However, in certain scenarios—particularly when a port conflict occurs—changing the port may be necessary.

Here is one method to change the default port of Electron Forge by modifying the webpack configuration (assuming you are using the webpack plugin):

1. Open the webpack configuration file: In an Electron Forge project, there are typically files named webpack.main.config.js and webpack.renderer.config.js that configure webpack behavior.

2. Modify the devServer option: In the webpack.renderer.config.js file, locate the devServer section, which is specifically used to configure the development server options. For example:

   javascript
   const config = {
     // Other configurations...
     devServer: {
       port: 3000, // Default port
       // Other server options...
     },
     // Other configurations...
   };

3. Change the port number: Update the value of port to your desired port number. For instance, if you want to set the port to 4000, modify it as follows:

   javascript
   devServer: {
       port: 4000,
   }

4. Save and restart the development server: Save the changes to the configuration file and restart the Electron Forge development server. This can be done by stopping the currently running server and then re-executing npm start or yarn start.

5. Verify the changes: After launching the application, confirm it is successfully running on the new port. Access it via http://localhost:4000 (or any port you configured) in a browser.

This process involves basic configuration adjustments. Always back up your configuration files before making any changes to facilitate restoring to the original settings if needed. If your configuration does not include webpack, consult the Electron Forge documentation or other relevant configuration files to identify the correct modification approach.
