Ionic App Development

General Ionic Framework development — core concepts, component reference, CLI usage, layout, theming, utilities, development workflow, and troubleshooting.

Prerequisites

Node.js (latest LTS) installed.
Ionic CLI installed globally (npm install -g @ionic/cli).
An existing Ionic project. For creating a new Ionic app, use the ionic-app-creation skill.

Agent Behavior

Auto-detect the framework. Check package.json for @ionic/angular, @ionic/react, or @ionic/vue to determine the framework in use. Adapt code examples accordingly.
Route to reference files. This skill is an overview that routes agents to specific reference files for detailed component APIs and topic-specific guidance.
Do not duplicate framework-specific skills. For Angular, React, or Vue specific patterns, refer to the respective framework skill.

Core Concepts

How Ionic Works

Ionic Framework is a UI toolkit for building cross-platform apps using web technologies (HTML, CSS, JavaScript/TypeScript). It provides a library of pre-built UI components that adapt their styling to the platform (ios or md mode).

Components are custom HTML elements (Web Components) prefixed with ion- (e.g., <ion-button>, <ion-content>).
Platform modes: Ionic renders components differently based on the platform. iOS devices use the ios mode; Android and all other platforms use the md (Material Design) mode. The <html> element receives a class (ios or md) that enables platform-specific styles.
Capacitor integration: Ionic apps use Capacitor to access native device features. Ionic handles the UI; Capacitor handles native APIs. See the capacitor-app-development skill for Capacitor-specific guidance.

Page Lifecycle

Ionic provides lifecycle events on top of the framework's own lifecycle hooks. These fire when a page is navigated to or from:

Event	Description
`ionViewWillEnter`	Fires when the page is about to enter and become active.
`ionViewDidEnter`	Fires when the page has fully entered and is now active.
`ionViewWillLeave`	Fires when the page is about to leave and become inactive.
`ionViewDidLeave`	Fires when the page has fully left and is now inactive.

These are in addition to the framework-specific lifecycle hooks (e.g., Angular's ngOnInit, React's useEffect, Vue's onMounted). Use Ionic lifecycle events for tasks that should run each time a page becomes visible (e.g., refreshing data), since some navigation strategies cache pages.

Component Reference

Ionic provides 80+ UI components. Detailed API documentation for each component is organized into reference files by category. Each reference file covers properties, events, methods, slots, CSS shadow parts, and CSS custom properties.

When the user needs help with a specific component, read the corresponding reference file.

Category	Reference File	Components Covered
Action & Buttons	`references/components-action.md`	action-sheet, button, fab, fab-button, fab-list, ripple-effect
Data Display	`references/components-data-display.md`	accordion, accordion-group, badge, card, card-content, card-header, card-subtitle, card-title, chip, item, item-divider, item-group, item-sliding, item-options, item-option, label, list, list-header, note, text
Form	`references/components-form.md`	checkbox, datetime, datetime-button, input, input-otp, input-password-toggle, picker, radio, radio-group, range, searchbar, select, select-option, segment, segment-button, segment-content, segment-view, textarea, toggle
Layout	`references/components-layout.md`	app, content, grid, col, row, header, footer, toolbar, title, buttons, back-button, split-pane
Media	`references/components-media.md`	avatar, icon, img, thumbnail
Navigation	`references/components-navigation.md`	breadcrumb, breadcrumbs, menu, menu-button, menu-toggle, nav, nav-link, router, router-link, router-outlet, route, route-redirect, tabs, tab, tab-bar, tab-button
Overlay	`references/components-overlay.md`	alert, loading, modal, popover, toast, backdrop
Scroll & Virtual	`references/components-scroll.md`	infinite-scroll, infinite-scroll-content, refresher, refresher-content, reorder, reorder-group
Progress	`references/components-progress.md`	progress-bar, skeleton-text, spinner

Ionic CLI

The Ionic CLI is the primary tool for developing Ionic apps. Below are the most commonly used commands. Run ionic --help for the full and always up-to-date command list.

Installation

npm install -g @ionic/cli

If upgrading from the legacy ionic package:

npm uninstall -g ionic
npm install -g @ionic/cli

Key Commands

Command	Description
`ionic serve`	Start a local dev server with live reload.
`ionic serve --external`	Serve on all network interfaces (for testing on devices).
`ionic serve --port=<port>`	Serve on a custom port (default: 8100).
`ionic serve --prod`	Serve with production build configuration.
`ionic build`	Build the web app for production.
`ionic generate`	Generate pages, components, services (framework-dependent).
`ionic doctor check`	Check the project for common issues.
`ionic info`	Print system/environment info for bug reports.
`ionic repair`	Remove and recreate dependencies and platform files.

`ionic serve` Options

Option	Description
`--ssl`	Enable HTTPS (experimental).
`--no-livereload`	Serve without automatic reloading.
`--no-open`	Do not open a browser window automatically.
`--consolelogs`	Print app console output in terminal.
`--browser=<browser>`	Open in a specific browser (safari, firefox, google chrome).
`--browseroption=<path>`	Open a specific URL path (e.g., `/#/tab/dash`).

For framework-specific CLI options, pass them after --:

ionic serve -- --proxy-config proxy.conf.json

Layout

Read references/components-layout.md for the full API reference for layout components.

Grid System

Ionic uses a 12-column flexbox grid system (ion-grid, ion-row, ion-col). Columns expand to fill the row evenly unless a size attribute is specified (1-12).

Responsive breakpoints:

Breakpoint	Min Width	CSS Class Prefix
`xs`	0	(default)
`sm`	576px	`sizeSm`
`md`	768px	`sizeMd`
`lg`	992px	`sizeLg`
`xl`	1200px	`sizeXl`

CSS Utility Classes

Ionic provides responsive CSS utility classes for common styling needs:

Text: .ion-text-center, .ion-text-start, .ion-text-end, .ion-text-wrap, .ion-text-nowrap, .ion-text-uppercase, .ion-text-lowercase, .ion-text-capitalize
Padding: .ion-padding, .ion-padding-top, .ion-padding-bottom, .ion-padding-start, .ion-padding-end, .ion-padding-vertical, .ion-padding-horizontal, .ion-no-padding
Margin: .ion-margin, .ion-margin-top, .ion-margin-bottom, .ion-margin-start, .ion-margin-end, .ion-margin-vertical, .ion-margin-horizontal, .ion-no-margin
Display: .ion-display-none, .ion-display-block, .ion-display-flex, .ion-display-inline, .ion-display-grid
Float: .ion-float-left, .ion-float-right, .ion-float-start, .ion-float-end
Flex: .ion-justify-content-center, .ion-align-items-center, .ion-flex-row, .ion-flex-column, .ion-flex-wrap, .ion-flex-nowrap
Border: .ion-no-border

All utility classes support responsive breakpoint suffixes: ion-text-{breakpoint}-center (e.g., .ion-text-md-center applies at 768px+).

Theming

Colors

Ionic provides nine default colors: primary, secondary, tertiary, success, warning, danger, light, medium, dark. Apply via the color attribute on components:

<ion-button color="primary">Primary</ion-button>
<ion-button color="danger">Danger</ion-button>

Each color has six CSS custom properties:

--ion-color-{name} — Base color value
--ion-color-{name}-rgb — Base color in RGB format
--ion-color-{name}-contrast — Text color for readability
--ion-color-{name}-contrast-rgb — Contrast color in RGB format
--ion-color-{name}-shade — Darker variant (active/pressed states)
--ion-color-{name}-tint — Lighter variant (hover states)

To customize a color, override all six variables in :root:

:root {
  --ion-color-primary: #3880ff;
  --ion-color-primary-rgb: 56, 128, 255;
  --ion-color-primary-contrast: #ffffff;
  --ion-color-primary-contrast-rgb: 255, 255, 255;
  --ion-color-primary-shade: #3171e0;
  --ion-color-primary-tint: #4c8dff;
}

To add a custom color, define the CSS variables and create a class:

:root {
  --ion-color-favorite: #69bb7b;
  --ion-color-favorite-rgb: 105, 187, 123;
  --ion-color-favorite-contrast: #ffffff;
  --ion-color-favorite-contrast-rgb: 255, 255, 255;
  --ion-color-favorite-shade: #5ca56c;
  --ion-color-favorite-tint: #78c288;
}

.ion-color-favorite {
  --ion-color-base: var(--ion-color-favorite);
  --ion-color-base-rgb: var(--ion-color-favorite-rgb);
  --ion-color-contrast: var(--ion-color-favorite-contrast);
  --ion-color-contrast-rgb: var(--ion-color-favorite-contrast-rgb);
  --ion-color-shade: var(--ion-color-favorite-shade);
  --ion-color-tint: var(--ion-color-favorite-tint);
}

Global CSS Variables

Variable	Description
`--ion-background-color`	Background color of the app
`--ion-text-color`	Text color of the app
`--ion-font-family`	Font family of the app
`--ion-statusbar-padding`	Statusbar padding top of the app
`--ion-safe-area-top`	Adjust safe area inset top
`--ion-safe-area-right`	Adjust safe area inset right
`--ion-safe-area-bottom`	Adjust safe area inset bottom
`--ion-safe-area-left`	Adjust safe area inset left
`--ion-margin`	Default margin for margin utility classes
`--ion-padding`	Default padding for padding utility classes
`--ion-placeholder-opacity`	Opacity of placeholder text in inputs

Dark Mode

Ionic supports three dark mode approaches:

1. System Preference (Default)

Automatically applies dark palette based on the user's OS setting:

@import '@ionic/angular/css/palettes/dark.system.css';
/* or @ionic/react, @ionic/vue */

2. Always Dark

Forces dark mode regardless of system settings:

@import '@ionic/angular/css/palettes/dark.always.css';

3. CSS Class Toggle

Enables manual dark mode control via a CSS class:

@import '@ionic/angular/css/palettes/dark.class.css';

Add .ion-palette-dark to the <html> element to activate:

<html class="ion-palette-dark">

Add this meta tag to adjust system UI elements (scrollbars, etc.):

<meta name="color-scheme" content="light dark" />

Platform Styles

Ionic uses two modes for platform-specific styling:

Platform	Default Mode	Style
iOS	`ios`	Apple iOS design
Android	`md`	Material Design
Other / Web	`md`	Material Design

To preview a specific mode in the browser, add ?ionic:mode=ios or ?ionic:mode=md to the URL:

http://localhost:8100/?ionic:mode=ios

Target mode-specific styles in CSS:

.ios ion-toolbar {
  --background: #f8f8f8;
}

.md ion-toolbar {
  --background: #ffffff;
}

Developing

Previewing in the Browser

The primary development workflow is browser-based:

ionic serve

This starts a development server at http://localhost:8100 with live reload.

Use browser DevTools to simulate mobile devices:

Chrome: Cmd+Opt+I (Mac) / Ctrl+Shift+I (Windows/Linux), then toggle device toolbar
Safari: Cmd+Opt+R for Responsive Design Mode
Firefox: Cmd+Opt+M (Mac) / Ctrl+Shift+M (Windows/Linux)

Testing on Devices

For native functionality that requires a real device:

npx cap run android
npx cap run ios

For live reload on a device:

npx cap run android --livereload --external
npx cap run ios --livereload --external

Debugging Tips

Use the debugger keyword to set breakpoints in code.
Add ?ionic:mode=ios to the URL to preview iOS styles in the browser.
Use ionic info to collect environment info for troubleshooting.

Utilities

Animations

Ionic provides a framework-agnostic animation utility built on the Web Animations API. Import:

JavaScript/TypeScript: import {createAnimation} from '@ionic/core';
Angular: Inject AnimationController from @ionic/angular
React: Use CreateAnimation component from @ionic/react
Vue: import {createAnimation} from '@ionic/vue';

Key methods: addElement(), duration(), easing(), fromTo(), keyframes(), play(), pause(), stop(), onFinish().

Animations support grouping (parent-child), chaining (via play() promises), and integration with gestures.

For performance, prefer animating transform and opacity over height and width.

Gestures

Ionic provides a framework-agnostic gesture utility. Import:

JavaScript/TypeScript: import {createGesture} from '@ionic/core';
Angular: Inject GestureController from @ionic/angular
React: import {createGesture} from '@ionic/react';
Vue: import {createGesture} from '@ionic/vue';

Configuration options: el, gestureName, threshold, direction (x/y), maxAngle, gesturePriority, disableScroll, passive.

Callbacks: canStart, onWillStart, onStart, onMove, onEnd, notCaptured.

The GestureDetail object provides startX/startY, currentX/currentY, deltaX/deltaY, and velocityX/velocityY.

Hardware Back Button (Android)

Ionic emits an ionBackButton event when the Android hardware back button is pressed. Handlers are priority-based:

Priority	Handler
100	Overlays
99	Menu
0	Navigation

For Capacitor apps, install @capacitor/app to enable hardware back button support. See the framework-specific skills for implementation patterns.

Error Handling

ionic: command not found: The Ionic CLI is not installed. Run npm install -g @ionic/cli.
Port 8100 in use: Another process is using the default port. Run ionic serve --port=<other-port>.
Components not rendering: Verify the Ionic CSS files are imported in the global stylesheet. For Angular: @import '@ionic/angular/css/core.css';. For React/Vue: check the framework-specific import.
Platform styles not applied: Ensure @ionic/angular, @ionic/react, or @ionic/vue is installed and configured. The <html> element should have an ios or md class.
Dark mode not working: Verify the correct dark palette CSS import is present. For the class method, ensure .ion-palette-dark is applied to the <html> element.
CSS custom properties not applying: Ionic components use Shadow DOM. Use the component's documented CSS custom properties (e.g., --background, --color) rather than targeting internal elements directly. Check the component reference file for available properties.
Live reload not working on device: Ensure the device and development machine are on the same network. Use the --external flag with npx cap run.
ionViewWillEnter not firing: This lifecycle event only fires with Ionic's routing components (ion-router-outlet). It does not fire with standard framework routers unless Ionic's routing integration is used.
