The Ionic Framework command line utility makes it easy to start, build, run, and emulate Ionic apps. In addition, it comes with (optional!) integration with the Ionic Cloud, a set of mobile backend services perfect for Ionic apps.

Use the ionic --help command for more detailed task information.


$ npm install -g ionic

Note: For a global install of -g ionic, OSX/Linux users may need to prefix the command with sudo or can setup proper file permissions on OSX for npm to install without sudo.

Minimal node requirements:

NodeLTS or greaterNPM 3x

Starting an Ionic App

To start a Ionic 1x app, run:

$ ionic start myapp [template]

To start a Ionic 2 app, run:

$ ionic start myapp [template] --v2

Starter templates can either come from a named template, a Github repo, a Codepen, or a local directory. A starter template is what becomes the www directory for a V1 project, and a srcdirectory for a V2 project

Named V1 template starters:






Named V2 template starters:

tabs (Default)



Github Repo starters:

Any Github repo url, ex: templates are simply aliases to Ionic starter repos

Local directory starters:

Relative or absolute path to a local directory

Adding a platform target

$ ionic platform ios android

Testing in a Browser

Use ionic serve to start a local development server for app dev and testing. Additionally, this command starts LiveReload which is used to monitor changes in the file system. As soon as you save a file the browser is refreshed automatically. View Using Sass if you would also like to have ionic serve watch the project's Sass files.

$ ionic serve

Building your app

$ ionic build ios

Emulating your app

Deploys the Ionic app on specified platform emulator. This is simply an alias for run --emulator.

$ ionic emulate ios [options]

Running your app

Deploys the Ionic app on specified platform devices. If a device is not found it'll then deploy to an emulator/simulator.

$ ionic run ios [options]

Icon and Splash Screen Image Generation

Since each platform has different image requirements, it's best to make a source image for the largest size needed, and let the CLI do all the resizing, cropping and copying for you. Newly generated images will be placed in the resources directory at the root of the Cordova project. Additionally, the CLI will update and add the correct <platform> configs to the project's config.xml file.

During the build process, Cordova (v3.6 or later) will look through the project's config.xml file and copy the newly created resource images to the platform's specific resource folder. For example, Android's resource folder can be found in platforms/android/res, and iOS uses platforms/ios/APP_NAME/Resources.

Icon Source Image

Save an icon.png, icon.psd or file within the resources directory at the root of the Cordova project. The icon image's minimum dimensions should be 192x192 px, and should have no rounded corners. Note that each platform will apply it's own mask and effects to the icons. For example, iOS will automatically apply it's custom rounded corners, so the source file should not already come with rounded corners. This Photoshop icon template provides the recommended size and guidelines of the artwork's safe zone.

$ ionic resources --icon

Splash Screen Source Image

Save a splash.png, splash.psd or file within the resources directory at the root of the Cordova project. Splash screen dimensions vary for each platform, device and orientation, so a square source image is required the generate each of various sizes. The source image's minimum dimensions should be 2208x2208 px, and its artwork should be centered within the square, knowning that each generated image will be center cropped into landscape and portait images. The splash screen's artwork should roughly fit within a center square (1200x1200 px). This Photoshop splash screen template provides the recommended size and guidelines of the artwork's safe zone. Additionally, when the Orientation preference config is set to either landscape or portraitmode, then only the necessary images will be generated.

$ ionic resources --splash

Photoshop Splash Screen Template

Generating Icons and Splash Screens

To generate both icons and splash screens, follow the instructions above and run:

$ ionic resources

Platform Specific Resource Images

One source image can be used to generate images for each platform by placing the file within the resources directory, such as resources/icon.png. To use different source images for individual platforms, place the source image in the respective platform's directory. For example, to use a different icon for Android, it should follow this path: resources/android/icon.png, and a different image for iOS would use this path: resources/ios/icon.png.

Generating Exact Platform Resources

By default the ionic resources command will automatically figure out which platforms it should generate according to what platforms have been added to your project. However, you can also explicitly state which resources should be built by providing a platform name in the command. The example below would generate only iosresources (even if the platform hasn't been added to the project).

$ ionic resources ios

Default Ionic Resources

Ionic provides you some default icons and splash screens to give you a better idea of how to size your icons and splashscreen, as well as how to modify your config.xml file for your own icons.

$ ionic resources --default

If you already have a resources directory, the command above will not over write your files. If you wish to force an over write, use ionic resources --default --force.

When starting a new app and adding a platform ionic platform add ios - the default icons and splashscreens will be downloaded and your config.xml will be modified to set up the default resources. This should help you identify your Ionic apps easier as well as help you get the file structure and configuration correct.

Crosswalk for Android

ionic plugin add cordova-plugin-crosswalk-webview --save

All that is left is to run the project as normal - ionic run android.

Advanced serve options


{ "name": "myApp", "app_id": "", "watchPatterns": [ "www/js/*", "!www/css/**/*" ] }

For a reference on glob pattern syntax, check outglobbing patterns on the Grunt website.

Gulp Integration

When running ionic serve, you can have Ionic run any Gulp tasks you specify by putting them into a gulp task called serve:before:

gulp.task('serve:before', ['sass', 'watch']);

Now, when you run ionic serve, it will run the watch task while starting the Ionic server.

If you would like to disable gulp from running during serve, pass the --nogulp option.

Your gulpfile must be named gulpfile.js or Gulpfile.js, there is currently no support for typescript, babel or coffeescript gulp files in the 2.0 CLI

NOTE For V1:

$ ionic setup sass

will add a watchPatterns propery with the default values to your ionic.config.json file that you can then edit, in addition to the serve:before gulp task described in the Using Sass section.

Service Proxies:

The serve command can add some proxies to the http server. These proxies are useful if you are developing in the browser and you need to make calls to an external API. With this feature you can proxy request to the external api through the ionic http server preventing the No 'Access-Control-Allow-Origin' header is present on the requested resource error.

In the ionic.config.json file you can add a property with an array of proxies you want to add. The proxies are object with the following properties:

path: string that will be matched against the beginning of the incoming request URL.proxyUrl: a string with the url of where the proxied request should go.proxyNoAgent: (optional) true/false, if true opts out of connection pooling, see HttpAgent

{ "name": "appname", "email": "", "app_id": "", "proxies": [ { "path": "/v1", "proxyUrl": "" } ] }

Using the above configuration, you can now make requests to your local server at http://localhost:8100/v1 to have it proxy out requests to

For example:

angular.module('starter.controllers', []) .constant('InstagramApiUrl', '') // .contant('InstagramApiUrl','') //In production, make this the real URL .controller('FeedCtrl', function($scope, $http, InstagramApiUrl) { $scope.feed = null; $http.get(InstagramApiUrl + '/v1/media/search?client_id=1&lat=48&lng=2.294351').then(function(data) { console.log('data ' , data) $scope.feed = data; }) })

Using Ionic Labs

$ ionic serve --lab

If you've used the serve command before, you'll feel right at home with this one. Just like serve, it opens your app in a browser, but now it shows you what your app will look like on a phone, with both iOS, Android, Windows side by side.

And of course, it supports Live Reload and all the other goodies we've added over the last couple of months.

NOTE: This does not emulate cordova or cordova plugins. So while the UI may feel like a native app, you'll still want to deploy to a device to test plugins.

Serving an alternate document root

If you'd like to test your app in the browser and you use a folder other than the default of www, you can specify this folder in your ionic.config.json file.

You might also want to have the document root be created if you use some sort of build system, we suggest using createDocumentRoot for that so that ionic serve will create that folder for you.

It is also advised you specify the watch patterns for this document root as well, as follows:

{ "name": "SmoothRiders", "documentRoot": "app", "createDocumentRoot": "app", "watchPatterns": [ "app/js/*", "!app/css/**/*" ] }

Packaging an app (beta)

Using Ionic's service, you can compile and package your project into an app-store ready app without requiring native SDKs on your machine.

$ ionic package debug android

The third argument can be either debug or release, and the last argument can be either android or ios.

Cordova Commands

Note: we occasionally send anonymous usage statistics to the Ionic team to make the tool better.

Working around proxies

If you have a proxy you need to get around, you can pass that proxy with the default http_proxynode environment variable or an environment variable proxy.

A few ways to set up and use the environment variable:

export # Or export ionic start my_app # Additionally, pass in line ionic start my_app

Using Sass (V1 Only)

By default, V1 starter projects are hooked up to Ionic's precompiled CSS file, which is found in the project's www/lib/ionic/css directory, and is linked to the app in the head of the root index.html file. However, projects can also be customized using Sass, which gives developers and designers "superpowers" in terms of creating and maintaining CSS. Below are two ways to setup Sass for your Ionic project (the ionic setup sass command simply does the manual steps for you). Once Sass has been setup for your Ionic project, then the ionic servecommand will also watch for Sass changes.

Ionic Cloud services

There are a few things you can utilize the CLI for to support ease of development.


Type ionic login to get logged in the CLI.

Login without prompt

You can pass the email and password to login without being prompted for email and password.

ionic login --email --password somepass

Login with environment variables

The CLI also supports settings environment variables to read off the email and password for the user.

Set IONIC_EMAIL and IONIC_PASSWORD as variables to have the CLI read these instead of being prompted for them.

Upload your Ionic app

Now you can use the ionic view app to view that application or have others view the application.

After uploading the application, you will see a message:

Uploading app.... Successfully uploaded (f23j9fjs)

This indicates you uploaded the application correctly, and the App ID is set to f23j9fjs.

You can then view that App ID from the View app or the application listing on your Ionic Cloud dashboard.

Adding a note with your upload

To add a note to your build, pass the --noteoption as follows:

ionic upload --note "This version of the application fixes the menu selections".

Set your Ionic Project App ID manually

Use the ionic link <appId> command to set your Ionic App ID to continue working with the same app with the Ionic platform across development enviroments.

Share the application with another user

Use the ionic share <email> command to have an email sent to another person to have them view the Ionic application you are using. Note: You must have an Ionic Cloud account as well as the user you are sharing with.

Ionic Hooks (V1)

In 1.3.18, the hooks were automatically removed due to some errors users were having with Crosswalk and other plugins with variables.

If you were a user who would still like to use those hooks, you can re-install these hooks with the ionic hooks add command.

If you would like to remove these hooks yourself, use ionic hooks remove to get rid of them.
