Create a new app ionic
1. Install Node.js and NPM: Before you start creating your Ionic app, you need to install Node.js and NPM (Node Package Manager) on your computer. You can download and install them from the official website: .2. Install Ionic CLI: Once you have Node.js and NPM installed, you can install the Ionic CLI by running the following command in your terminal or command prompt:
npm install -g @ionic/cli
This command will install the latest version of the Ionic CLI globally on your system.
1. Create a new Ionic app: To create a new Ionic app, run the following command in your terminal or command prompt:
ionic start myApp
To create a new app with a specific template, you can use the --type option followed by the template name. For example, to create a new app with the blank template, run the following command:
ionic start myApp --type=blank
1. Run the app: Once you have created your app, you can run it in the browser by running the following command:
cd myApp
ionic serve
This will start a local development server and open your app in the default web browser. You can make changes to your app and see the changes live in the browser.
That's it! You have now created a new Ionic app and are ready to start building your own mobile app.
We need to generate pages
To create a new page in an Ionic project using the ionic g page command, follow these steps:1. Open a terminal or command prompt and navigate to the root directory of your Ionic project.
2. Type the following command in the terminal:
Replace page-name with the name you want to give to your new page. For example, if you want to create a page named home, you would type:
1. Press Enter to execute the command.
2. Ionic will generate the files and folders required for the new page in the src/app directory of your project.
3. The generated files will include a .html file for the page's markup, a .ts file for its TypeScript code, and a .scss file for its styles.
4. If your Ionic project uses lazy loading, the ionic g page command will also update the app-routing.module.ts file to include the new page.
5. That's it! You can now use the new page in your Ionic app.
ion-menu
The Menu component is a navigation drawer that slides in from the side of the current view. By default, it slides in from the left, but the side can be overridden. The menu will be displayed differently based on the mode, however the display type can be changed to any of the available menu types. The menu element should be a sibling to the root content element. There can be any number of menus attached to the content. These can be controlled from the templates, or programmatically using the MenuController.
ionic g page flutter
ionic g page ionic
ionic g page main
ionic g page menu
Your page html look like this
ionic.page.html
<ion-header>
<ion-toolbar> color="primary">
<ion-buttons slot="start">
<ion-menu-button></ion-menu-button>
<ion-title>Ionic Page</ion-title>
</ion-buttons>
</ion-toolbar>
</ion-header>
<ion-content>
<div style="padding: 20px;">
Lorem ipsum dolor sit amet consectetur adipisicing elit. Dolore laborum eum neque minima velit facilis necessitatibus quod libero. Debitis deserunt totam cumque saepe, fugit blanditiis nostrum hic obcaecati illum. Dolor.
</div>
</ion-content
RouterModule
We need to create routes in menu page routing.ts
In Ionic, you can define routes with children routes using the RouterModule from @angular/router. Here's an example of how to do it:1. Create a parent route with a path and a component:
menu.routing.modules.ts
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { MenuPage } from './menu.page';
const routes: Routes = [
{
path: '',
redirectTo: '/menu/main',
pathMatch: 'full'
},
{
path: '', component: MenuPage,
children: [
{
path: 'main',
loadChildren: () => import('../main/main.module').then( m => m.MainPageModule)
},
{
path: 'ionic',
loadChildren: () => import('../ionic/ionic.module').then( m => m.IonicPageModule)
},
{
path: 'flutter',
loadChildren: () => import('../flutter/flutter.module').then( m => m.FlutterPageModule)
},
]},
];
@NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule],
})
export class MenuPageRoutingModule {}
In the above example, we have defined a parent route with a path of '/menu/main', 'main', 'ionic', and 'flutter' and a component of ParentComponent. The children property is an array of child routes that are associated with the parent route.
1. Add the RouterModule to your imports array in the @NgModule decorator:
To use ion-menu in Ionic 7, you can follow these steps:
1. Create a new Ionic project or use an existing one.
2. Add the ion-menu component to your HTML template. The ion-menu component creates a slide-out menu that can be opened by swiping from the left side of the screen.
<ion-menu contentId="content">
<ion-header>
<ion-toolbar color="primary">
<ion-title>menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<div *ngFor="let p of pages">
<ion-menu-toggle *ngIf="p.url">
<ion-item [routerLink]="p.url" routerDirection="root" routerLinkActive="active">
<ion-icon [name]="p.icon" slot="start"></ion-icon>
<ion-label>
{{p.title}}
</ion-label>
</ion-item>
</ion-menu-toggle>
<ion-item button *ngIf="p.children?.length > 0" (click)="p.open = !p.open" [class.active-parent]="p.open" detail="false">
<ion-icon slot="start" name="arrow-forward" *ngIf="!p.open"></ion-icon>
<ion-icon slot="start" name="arrow-down" *ngIf="p.open"></ion-icon>
<ion-label>{{p.title}}</ion-label>
</ion-item>
<ion-list *ngIf="p.open">
<ion-menu-toggle>
<ion-item class="sub-item" *ngFor="let sub of p.children" [routerLink]="sub.url" routerDirection="root" routerLinkActive="active">
<ion-icon [name]="sub.icon" slot="start"></ion-icon>
<ion-label>
{{sub.title}}
</ion-label>
</ion-item>
</ion-menu-toggle>
</ion-list>
</div>
</ion-content>
</ion-menu>
<ion-router-outlet id="content" main></ion-router-outlet>
In the above example, the ion-menu component is added with side="start", which means it will slide out from the left side of the screen. The menuId attribute is used to identify the menu, which is required when using other components that interact with the menu, such as the ion-menu-button.
Add a button to open the menu. The ion-menu-button component creates a button that toggles the menu when clicked.
In the above example, the ion-menu-button is added with menu="main-menu", which links it to the ion-menu component with menuId="main-menu". The autoHide attribute is set to false, which prevents the menu from automatically closing when an item is clicked.
Custom CSS (Cascading Style Sheets) is a way to style HTML elements beyond what is available through standard HTML attributes. It allows you to customize the appearance of your website, such as font size, color, background, layout, and more.
To add custom CSS to your website, you need to create a CSS file and link it to your HTML document. Here are the steps to add custom CSS:
Create a CSS file: Create a new file with a .css extension, for example, style.css. You can create this file using a text editor like Notepad or a code editor like Visual Studio Code.
Write your CSS: Add your custom CSS code to the file. Here's an example of how you could change the font size of all paragraphs on your website:
menu.page.css
.active {
--ion-text-color: var(--ion-color-primary );
ion-icon {
--ion-text-color-rgb: var(--ion-color-primary );
}
}
.active-parent {
font-weight: 500 ;
}
.sub-item {
padding-left: 20px;
font-size: small;
}
In this example, the type attribute is set to "overlay", which creates an overlay-style menu. The swipeGesture attribute is set to true, which allows the user to swipe to open and close the menu. The contentId attribute is set to the ID of the main content area, which allows the menu to push the content area aside when opened.
Test the menu by running the app on a device or emulator.
That's it! With these steps, you can use the ion-menu component in your Ionic 7 app.
