Best way is to update the serve script command in your package json file  Just append --port 3000 like so    scripts        serve    vue-cli-service serve --port 3000      build    vue-cli-service build      inspect    vue-cli-service inspect      lint    vue-cli-service lint

Oh my God  It is not that much complicated  with these answers which also works  However  other answers tho this question also works well  If you really want to use the vue-cli-service and if you want to have the port setting in your package json file  which your  vue create  lt app-name gt   command basically creates  you can use the following configuration  --port 3000  So the whole configuration of your script would be like this       quot scripts quot      quot serve quot    quot vue-cli-service serve --port 3000 quot    quot build quot    quot vue-cli-service build quot    quot lint quot    quot vue-cli-service lint quot          I am using  vue cli 4 3 1  vue --version  on a macOS device  I have also added the vue-cli-service reference  https   cli vuejs org guide cli-service html

There are a lot of answers here varying by version  so I thought I d confirm and expound upon Julien Le Coupanec s answer above from October 2018 when using the Vue CLI  In the most recent version of Vue js as of this post - vue 2 6 10 - the outlined steps below made the most sense to me after looking through some of the myriad answers in this post  The Vue js documentation references pieces of this puzzle  but isn t quite as explicit    Open the package json file in the root directory of the Vue js project  Search for  port  in the package json file  Upon finding the following reference to  port   edit the serve script element to reflect the desired port  using the same syntax as shown below    scripts        serve    vue-cli-service serve --port 8000      build    vue-cli-service build      lint    vue-cli-service lint     Make sure to re-start the npm server to avoid unnecessary insanity    The documentation shows that one can effectively get the same result by adding --port 8080 to the end of the npm run serve command like so  npm run serve --port 8080  I preferred editing the package json directly to avoid extra typing  but editing npm run serve --port 1234 inline may come in handy for some

In the webpack config js   module exports                devServer        historyApiFallback  true      port  8081       you can change the port there     noInfo  true      overlay  true                   You can change the port in the module exports -  devServer -  port   Then you restrat the npm run dev  You can get that

An alternative approach with vue-cli version 3 is to add a  env file in the root project directory  along side package json  with the contents   PORT 3000  Running npm run serve will now indicate the app is running on port 3000

As the time of this answer s writing  May 5th 2018   vue-cli has its configuration hosted at  lt your project root gt  vue config js  To change the port  see below       vue config js module exports                devServer        open  process platform      darwin       host   0 0 0 0       port  8080     CHANGE YOUR PORT HERE      https  false      hotOnly  false                    Full vue config js reference can be found here  https   cli vuejs org config  global-cli-config  Note that as stated in the docs     All options for webpack-dev-server     https   webpack js org configuration dev-server   is available within the devServer section

Another option if you re using vue cli 3 is to use a config file  Make a vue config js at the same level as your package json and put a config like so   module exports       devServer        port  3000         Configuring it with the script   npm run serve --port 3000   works great but if you have more config options I like doing it in a config file  You can find more info in the docs

The port for the Vue-cli webpack template is found in your app root s myApp config index js    All you have to do is modify the port value inside the dev block    dev        proxyTable          env  require    dev env        port  4545      assetsSubDirectory   static       assetsPublicPath           cssSourceMap  false       Now you can access your app with localhost 4545   also if you have  env file better to set it from there

If you re using vue-cli 3 x  you can simply pass the port to the npm command like so   npm run serve -- --port 3000  Then visit http   localhost 3000
