Webpack-dev-server: Browser automatically open can't be disabled

[vzorge]

• Operating System: Windows 10
• Node Version: 8.9.3
• NPM Version: 4.5.0
• webpack Version: 3.10.0

• webpack-dev-server Version: 2.11.1

• [x] This is a bug

• [ ] This is a modification request

When I set the open flag to false, it does not prevent the browser from opening.
In my webpack.config.js:
devServer: { open: false }

Expected Behavior

I expect the browser NOT to open

Actual Behavior

The browser opens

For Bugs; How can we reproduce the behavior?

Self explanatory. Even a simple server with 'open:false' will still have this bug.

Ok turned out someone had altered the scripts to start the webserver with the --open option.

I have webpack 4 but this is not working

@kasaiee try this

modify your package.json file, like below code shows

{
  "scripts": {
    "dev": "webpack-dev-server --open --config ./build/webpack.config.js",
  }
}
