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 Platform, a set of mobile 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
$ ionic start myapp [template]
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 within the Cordova project.
Named 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 [--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. This is useful for both desktop browser testing, and to test within a device browser which is connected to the same network. 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
emulate command will deploy the app to the specified platform devices/emulators. You can also run live reload on the specified platform device by adding the
--livereload option. The live reload functionality is similar to
ionic serve, but instead of developing and debugging an app using a standard browser, the compiled hybrid app itself is watching for any changes to its files and reloading the app when needed. This reduces the requirement to constantly rebuild the app for small changes. However, any changes to plugins will still require a full rebuild. For live reload to work, the dev machine and device must be on the same local network, and the device must support web sockets.
With live reload enabled, an app's console logs can also be printed to the terminal/command prompt by including the
-c option. Additionally, the development server's request logs can be printed out using
Command-line flags/options for
[--livereload|-l] ....... Live Reload app dev files from the device (beta) [--consolelogs|-c] ...... Print app console logs to Ionic CLI (live reload req.) [--serverlogs|-s] ....... Print dev server logs to Ionic CLI (live reload req.) [--port|-p] ............. Dev server HTTP port (8100 default, live reload req.) [--livereload-port|-i] .. Live Reload port (35729 default, live reload req.) [--all|-a] .............. Specify to run on all addresses, 0.0.0.0, so you can view externally [--browser|-w] .......... Specifies the browser to use (safari, firefox, chrome) [--browseroption|-o] .... Specifies a path to open to (/#/tab/dash) [--debug|--release]
While the server is running for live reload, you can use the following commands within the CLI:
restart or r to restart the client app from the root goto or g and a url to have the app navigate to the given url consolelogs or c to enable/disable console log output serverlogs or s to enable/disable server log output quit or q to shutdown the server and exit
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.
In v1.3.0 and later, you can now specify which browser to use in your Cordova Android projects. Currently we only support Crosswalk and have plans to support more browsers later.
ionic browser add crosswalk to add the Crosswalk browser to your Android project. By default, this will install the
12.41.296.5 version of Crosswalk.
If you'd like to specify a different version of Crosswalk, run
ionic browser list to see which browsers are available and what versions. Then run
ionic browser add email@example.com.
All that is left is to run the project as normal -
ionic run android.
If you'd like to build without Crosswalk for Android SDK 21 or later, do the following:
ionic browser revert androidionic build android --release -- --minSdkVersion 21
By default, LiveReload will watch for changes in your
www/lib/. To change this, you can specify a
property in the
ionic.project 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 your
ionic.project as a
gulpStartupTasks property as follows:
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
$ ionic setup sass
will add a
watchPatterns propery with the default values to your
file that you can then edit, in addition to the
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.project 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 and Android 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 and Android side by side.
And of course, it supports Live Reload and all the other goodies we've added over the last couple of months.
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:
Update Ionic library files, which are found in the
www/lib/ionic directory. If bower is being used
by the project, this command will automatically run
bower update ionic, otherwise this command updates
the local static files from Ionic's CDN.
$ ionic lib update
Note: Using bower? This command does not update Ionic's dependencies. Run
bower update to update Ionic and all of it's dependencies defined in
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, 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, Ionic 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.
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
"gulpStartupTasks": ["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 ionic.io.
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.io account as well as the user you are sharing with.
To get Ionic documentation from the Ionic CLI, try using the
ionic docs command. The command will look up your currently used Ionic version and open the docs specific for that version. Ex: RC0, RC1, etc.
To view all docs,
ionic docs ls.
To get help with a doc you may not remember, just type the name close enough:
ionic docs list and you will be prompted for suggestions that may match.
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.
Ionic now provides a command to help you manage the state of your Ionic application. Previously Cordova hooks were used to save platforms and plugins to your
Now when using
ionic platform add,
ionic platform rm,
ionic plugin add, or
ionic plugin rm, the state command will automatically be used to save the platform or plugin state to the
If you would like to avoid saving plugins or platforms to the
package.json file - pass in the
--nosave option. (
ionic plugin add org.apache.cordova.file --nosave).
Your package.json file might look something like the following:
ionic state save command does some lookup in your platforms and plugins to save the current state of your cordova application.
First it looks in your platforms folder to see which platforms are installed, and saves the name and version in your
package.json file under the
Second it looks at your plugins
fetch.json file to save the plugins installed both from the Cordova registry, locally installed plugins, as well as remote plugins from github or a remote HTTP url.
ionic state restore command looks at the
cordovaPlatforms attributes in your
package.json file to restore your application with those platforms and plugins.
In the package.json file,
cordovaPlugins will be stored as just their
ID if they are installed from the Cordova registry. However, if they are local or remote, they will be stored as an object with those properties. Also to note, variables are stored for plugins with variables like the Facebook connect plugin.
cordovaPlatforms follow the same convention of either an
ID for the platform name, if they are local or remote, they will be stored as an object with those properties.
If you'd like, you can populate the
cordovaPlatforms by hand, then use the
ionic state restore command to get your app ready to go.
ionic state clear method will clear out your platforms and plugins directories, as well as removing the
cordovaPlaforms attributes in your
ionic state reset method will first remove your platforms and plugins folders. Then it will look at your
package.json file to re-install the platforms and plugins as specified there.
This command can be helpful for you to reinstall your plugins and platforms to get a fresh start.
