How to change electron-forge default port?

Question

I can't find reference about this anywhere in their website\/docs. I need to change this to another port, currently it's stuck in 3000.

yarn create electron-app my-new-app --template=typescript

Answer 1

I just started out using electron-forge and ran into the same issue, and it seemed like the electron/webpack was ignoring my devServer.port value.

After finding this doc for the electron-forge config I realized the devServer.port is probably overwritten by electron-forge, and the values for the config were set in package.json. Here was mine:

{
  "name": "my-project",
  // ...
  "config": {
    "forge": {
      "packagerConfig": {},
      "makers": [
        // ...
      ],
      "plugins": [
        [
          "@electron-forge/plugin-webpack",
          {
            "mainConfig": "./webpack.main.config.js",
            "renderer": {
              "config": "./webpack.renderer.config.js",
              "entryPoints": [
                {
                  "html": "./src/index.html",
                  "js": "./src/renderer.js",
                  "name": "main_window"
                }
              ]
            },

            // the secret sauce:
            "port": 3001,
            "loggerPort": 9001
          }
        ]
      ]
    }
  }
}

Follow instructions here to setup Webpack configuration for your project (if not already done): https://www.electronforge.io/config/plugins/webpack

Then, follow the instructions here to change the devServer.port option: https://webpack.js.org/configuration/dev-server/

As an update to this question, I was unable to replicate the top-rated answer and eventually changed the default port with a slightly different approach by implementing this answer from another post.
