Ionic CLI

The Ionic command line interface (CLI) is your go-to tool for developing Ionic apps.

Use ionic --help for more detailed command information.

Table of Contents

Requirements

  • Node 6 LTS (latest)
  • npm 3+

Install

$ npm install -g ionic

📝 Note: For a global install -g ionic, macOS/Linux users may need to prefix with sudo or can setup proper file permissions for npm.

📝 Note: Running ionic will first look to see if you're in an Ionic project. If you are, it runs the locally installed CLI, if installed.

Getting Started

New projects are started with the ionic start command. For full details and examples, see:

ionic start --help

Here is a table of project types and links to their respective starter templates:

Project Type Start Command Starter Templates
Ionic Angular ionic start myApp blank, tabs, sidemenu, conference, tutorial, super
Ionic 1 ionic start myApp --type=ionic1 blank, tabs, sidemenu, maps

After you start your project, you can cd into the directory and serve it in your browser:

cd ./myApp
ionic serve

Using Cordova

Integrate Ionic with Cordova to bring native capabilities to your app.

Requirements

$ npm install -g cordova
$ ionic cordova --help
$ ionic cordova run ios

Integrations

As of CLI 3.8, the @ionic/cli-plugin-cordova and @ionic/cli-plugin-gulp have been deprecated in favor of integrations. Integrations are automatically detected and enabled, but can be easily disabled.

Integrations hook into CLI events. For example, when the Cordova integration is enabled, ionic cordova prepare will run after ionic build runs. See CLI Hooks.

integration enabled when... disabled with...
Cordova ionic cordova commands are run ionic config set integrations.cordova.enabled false
Gulp gulp exists in devDependencies of your package.json ionic config set integrations.gulp.enabled false

Environment Variables

The CLI will look for the following environment variables:

  • IONIC_CONFIG_DIRECTORY: Where the CLI config files live. Defaults to ~/.ionic. You may prefer ~/.config/ionic.
  • IONIC_HTTP_PROXY: Set a URL for proxying all CLI requests through. See Using a Proxy. The CLI will also look for HTTP_PROXY and HTTPS_PROXY, both of which npm use.
  • IONIC_EMAIL / IONIC_PASSWORD: For automatic login via environment variables.

CLI Flags

CLI flags are global options that alter the behavior of a CLI command.

  • --help: Instead of running the command, view its help page.
  • --verbose: Show all log messages for debugging purposes.
  • --quiet: Only show WARN and ERROR log messages.
  • --no-interactive: Turn off interactive prompts and fancy outputs. If a CI server is detected (we use ci-info), the CLI is automatically non-interactive.
  • --confirm: Turn on auto-confirmation of confirmation prompts. Careful: the CLI prompts before doing something potentially harmful. Auto-confirming may have unintended results.

CLI Config

The CLI provides commands for setting and printing config values from project config files and the global CLI config file. See ionic config set --help and ionic config get --help for usage.

CLI Hooks

CLI hooks are how you can run scripts during CLI events, such as "watch" and "build". To hook into the CLI, use the following npm scripts in your package.json file:

npm script description commands
ionic:watch:before Runs before the file watcher activates during a "watch" event ionic serve, ionic cordova run -l, ionic cordova emulate -l
ionic:build:before Runs before the Ionic "build" event starts. ionic build, ionic upload, ionic package build, ionic cordova build, ionic cordova run, ionic cordova emulate
ionic:build:after Runs after the Ionic "build" event finishes. ionic build, ionic upload, ionic package build, ionic cordova build, ionic cordova run, ionic cordova emulate

Example

  "scripts": {
    "ionic:build:before": "cp somefile www/somefile",
  }

📝 Note: If you use gulp, the CLI will run gulp tasks by the same name as the npm scripts above.

Service Proxies

The CLI can add proxies to the HTTP server for "livereload" commands like ionic serve, ionic cordova run android -lcs, or similar. 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 an 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",
  "app_id": "",
  "type": "ionic-angular",
  "proxies": [
    {
      "path": "/v1",
      "proxyUrl": "https://api.instagram.com/v1"
    }
  ]
}

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 https://api.instagram.com/v1.

📝 Note: Don't forget to change the URLs being requested in your app to the local URL. Also, the "livereload" command must be restarted for the proxy configuration to take effect.

Using a Proxy

To proxy HTTP requests performed by the CLI, you will need to install the CLI proxy plugin in the same node_modules context as the Ionic CLI:

For CLI installed globally:

$ npm install -g @ionic/cli-plugin-proxy

For CLI installed locally:

$ cd myProject # cd into your project
$ npm install --save-exact --save-dev @ionic/cli-plugin-proxy

Then, set the following environment variables:

$ export HTTP_PROXY=http://proxy.example.org:8888 # used by npm
$ export HTTPS_PROXY=https://proxy.example.org:8888 # used by npm
$ export IONIC_HTTP_PROXY=http://proxy.example.org:8888

For example:

$ HTTPS_PROXY=https://internal.proxy.com ionic start

Legacy Version

The old version of the CLI can be installed with the legacy tag:

npm install -g ionic@legacy
