A tool for creating and developing Ionic Framework mobile apps.
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.
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
Minimal node requirements:
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
src directory for a V2 project
Named V1 template starters:
Named V2 template starters:
Github Repo starters:
Codepen URL starters:
Plunker URL starters:
Local directory starters:
[--appname|-a] ....... Human readable name for the app (Use quotes around the name) [--id|-i] ............ Package name set in the <widget id> config ex: com.mycompany.myapp [--no-cordova|-w] .... Do not create an app targeted for Cordova [--sass|-s] ........... Setup the project to use Sass CSS precompiling (V1 only) [--list|-l] .......... List starter templates available [--io-app-id] ......... The Ionic.io app ID to use
$ ionic platform ios android
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 [options]
$ ionic build ios
Deploys the Ionic app on specified platform emulator. This is simply an alias for
$ ionic emulate ios [options]
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]
Automatically generate icons and splash screens from source images to create each size needed for each platform, in addition to copying each resized and cropped image into each platform's resources directory. Source images can either be a
psd Photoshop or
ai Illustrator file. Images are generated using Ionic's image resizing and cropping server, instead of requiring special libraries and plugins to be installed locally.
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
icon.ai 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.ai 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
portrait mode, then only the necessary images will be generated.
$ ionic resources --splash
To generate both icons and splash screens, follow the instructions above and run:
$ ionic resources
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:
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
ios resources (even if the platform hasn't been added to the project).
$ ionic resources ios
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.
To install Crosswalk for Android run:
ionic plugin add cordova-plugin-crosswalk-webview --save
All that is left is to run the project as normal -
ionic run android.
By default, for Ionic 1 projects, LiveReload will watch for changes in your
www/lib/. To change this, you can specify a
property in the
ionic.config.json file located in your project root to watch
(or not watch) for specific changes.
For a reference on glob pattern syntax, check out globbing patterns on the Grunt website.
ionic serve, you can have Ionic run any Gulp tasks you specify by putting them into a gulp task called
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
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
file that you can then edit, in addition to the
serve:before gulp task
described in the Using Sass section.
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.
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
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
angular// .contant('InstagramApiUrl','')//In production, make this the real URL

We've extended the serve command to open the new Lab UI that features iOS, Android, and Windows side-by-side.
$ 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.
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
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:
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
release, and the last argument can be either
Ionic uses Cordova underneath, so you can also substitute Cordova commands to prepare/build/emulate/run, or to add additional plugins.
Note: we occasionally send anonymous usage statistics to the Ionic team to make the tool better.
If you have a proxy you need to get around, you can pass that proxy with the default
http_proxy node environment variable or an environment variable
A few ways to set up and use the environment variable:
export http_proxy=internal.proxy.com# Orexport PROXY=internal.proxy.comionic start my_app# Additionally, pass in linePROXY=internal.proxy.com ionic start my_app
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 serve command will also watch for Sass changes.
For V2 projects, there's nothing you need to do! Ionic 2 projects by default are setup with sass and come with all the build process enabled.
ionic setup sass
npm installfrom the working directory of an Ionic project. This will install gulp.js and a few handy tasks, such as gulp-sass and gulp-minify-css.
<link href="lib/ionic/css/ionic.css" rel="stylesheet">from the
<head>of the root
<link href="css/style.css" rel="stylesheet">from the
<head>of the root
<link href="css/ionic.app.css" rel="stylesheet">to the
<head>of the root
serve:beforegulp task, add the
gulp.task('serve:before', ['sass', 'watch']);(this can also be customized to whatever gulp tasks you'd like).
There are a few things you can utilize the CLI for to support ease of development.
ionic login to get logged in the CLI.
You can pass the email and password to login without being prompted for email and password.
ionic login --email firstname.lastname@example.org --password somepass
The CLI also supports settings environment variables to read off the email and password for the user.
IONIC_PASSWORD as variables to have the CLI read these instead of being prompted for them.
ionic upload command to take your current application you are developing and upload it to the Ionic.io servers.
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
You can then view that App ID from the View app or the application listing on your Ionic Cloud dashboard.
To add a note to your build, pass the
--note option as follows:
ionic upload --note "This version of the application fixes the menu selections".
ionic link <appId> command to set your Ionic App ID to continue working with the same app with the Ionic platform across development enviroments.
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 provides some default hooks for you to use in your Cordova application. In versions prior to 1.3.18, these hooks were automatically installed via the
ionic platform command.
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.
First class support has come to the Ionic CLI to scaffold and generate Ionic and Angular 2 components.
From your app directory, use the
generate command (alias:
ionic g tabs MyTabPage- Generate a page named MyTabPage, queries for the amount of tabs, and creates pages for those tabs.
View all generators:
ionic g --list.
