Create-response-app: 如何使用特定的浏览器“ npm 启动”?

NPM 开始

在默认浏览器上启动响应服务器,对我来说就是 Firefox。我喜欢 Firefox 的浏览器,但是我更喜欢 Chrome 的开发工具。有没有一种方法可以强制“ npm 启动”启动服务器与 Chrome,而不改变我的默认浏览器铬?我在 Windows 上使用 Bash。

编辑: 我使用“ create-response-app”来创建我的服务器,这添加了一个 脚本到“ packages.json”文件中的“ npm start”。该脚本使用默认浏览器启动本地主机服务器。如何修改由“ create-response-app”添加的脚本,使其从不同的浏览器开始?

This is possible with the BROWSER environment variable.

You can also do it directly in the terminal: BROWSER=chrome npm start

This is described in the Advanced Configuration docs:

By default, Create React App will open the default system browser, favoring Chrome on macOS. Specify a browser to override this behavior, or set it to none to disable it completely. If you need to customize the way the browser is launched, you can specify a node script instead. Any arguments passed to npm start will also be passed to this script, and the url where your app is served will be the last argument. Your script's file name must have the .js extension.

Also note that the browser names are different on different platforms:

The app name is platform dependent. Don't hard code it in reusable modules. For example, Chrome is google chrome on macOS, google-chrome on Linux and chrome on Windows.

There is one package called set-default-browser https://www.npmjs.com/package/set-default-browser

just download package from there and add following code

var setDefaultBrowser = require('set-default-browser');


setDefaultBrowser("chrome");

Or you can just run this set-default-browser chrome

Thanks!

Add script to your package.json file

"devserver": "live-server --browser=Chrome"

To open in chrome we need to set it as a default browser.

Setting --> Default browser --> Make default -->

and choose chrome if any other browser is chosen.

It worked on windows 10.

Method by using .env file in the root of your NodeJS app.

BROWSER="firefox developer edition"

In Windows cmd, set env variable for desired browswer:

set BROWSER=chrome

Then just run npm start like normal

I don't like to repeatedly create a new .env file or prepend npm start every time with an additional command. You can specify your browser of choice instead of none in your shell config file. Type in your terminal the following commands:

echo export BROWSER=none >> ~/.bashrc
source ~/.bashrc

At this point you can run npm start and be happy.

As you have mentioned that you are using create-react-app for creating react app and you want chrome to open on hitting npm start. Set BROWSER variable in package.json present in your project in the following manner:

Replace:

"start": "react-scripts start"

With:

  • Linux:
    "start": "BROWSER='google-chrome-stable' react-scripts start"
    
  • Windows:
    "start": "BROWSER='chrome' react-scripts start"
    
  • OS X:
    "start": "BROWSER='google chrome' react-scripts start"
    

If you are a Windows user then go to Sitting -> Default apps -> Web browser then select your desired browser.If you are a Linux user then go to System-settings -> Details. (Note: In older versions of Ubuntu Details is called System Info)

Sitting of windows

Sitting of linux

Using above technique, you may end up with error 'BROWSER' is not recognized as an internal or external command, operable program or batch file.

To over come this Do an npm install of cross-env in your cloned repo: npm install --save cross-env

Try to use this command in the package.json file

"start": "cross-env BROWSER=chrome react-scripts start"

BROWSER is an environment variable, and you can use the cross-env package to properly handle it.

This is how I solved mine:

I opened the application on vsCode, then via the terminal I ran "BROWSER=Chrome npm start".

Simply add the env-cmd package as global

then create a .env file and write a variable with a specific Browsers path after that add the env-cmd just in your start script

in the terminal

npm install -g env-cmd

in the .env file

BROWSER= "your browser path"

like => BROWSER= "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Edge"

in the package.json add the env-cmd

"scripts": {
"start": "env-cmd react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
}

that should work!

for Brave browser it is BROWSER=brave-browser npm start

If you want to change the default browser when you are running a npm start or yarn start, the simplest way to do that is edit your package.json file.

Many are not comfortable dealing with environment variables using the terminal.

This is what your scripts section should look like:

"scripts": {
"start": "BROWSER=none react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},

In the above scenario it would not open any browser at all, you are free to choose your development browser and continue your work(I prefer this one). However, if you want a specific browser then you can replace BROWSER=none with any of the following:

  • BROWSER=firefox
  • BROWSER=google-chrome-stable
  • BROWSER=vivaldi

Suit yourself.

Change your default Browser setting in windows, if it does not work then open your visual studio code and change the script browser to:

"start": "BROWSER=chrome react-scripts start"

on windows, the easies way with create-react-app was to add BROWSER="C:\Program Files\Google\Chrome Dev\Application\chrome.exe" to my .env.developmennt.local file in each CRA project. I use a different browser without dev extensions as the default one set in the system.

On Mac, this method:

"start": "BROWSER='firefox developer edition' react-scripts start"

works on 'react': '17.0.1' together with 'react-scripts': '4.0.1'

But it is not working on 'react': '18.0.1' together with 'react-scripts': '5.0.1'.

On 18.0.1 it continues to open in the default browser set on my computer. So I have sometimes reverted back to using the older React version but do not want to continue doing this as I do need the newer version in some cases and it's just easier to install the most recent version using create-react-app.

Any suggestions?

If you are using another browser like Brave, here is an example on how to modify the package.json file.

In Mac OS

  "scripts": {
"start": "BROWSER='/Applications/Brave Browser.app' react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
}
