# Running the app

## Run the app on Browser

Once you have the [initial setup](/ionic-4-netflix-clone-template/initial-setup.md) done, it's time to run your app. First we'll run the app in development environment. In development environment, your app runs in a browser (of your choice). It is recommended to make all changes and development while running the app on browser . Running on device while developing will be too time consuming.‌

To run the app on browser, run

```
$ ionic serve
```

on your command line, inside your project folder. This will build the project and deploy it on a `localhost` url (usually it is `localhost:8100`). Your command line will look like this‌

![](/files/-Lqu3msP8JhZyODWLfUN)

The initial deploy process will take some time when it creates "chunks" of code pieces. Once you see `compiled successfully` , you are good to go. Your browser window will open automatically and load the app in a full screen view.‌

To change the app to a device view, right click anywhere on the browser and choose `Inspect Element`and choose device mode.‌
