Development of application pages-JS Tutorial-php.cn

Разработка страниц приложения

If you look at the original project, you can see that we need to create one main page.

Search results for flights, hotels and tours differ only in form. Therefore, there is no point in making multiple implementations.

Let's create a library:

mkdir src/app/home
mkdir src/app/home/page
mkdir src/app/home/page/lib
echo >src/app/home/page/index.ts

Copy after login

Generate the component:

yarn ng g c home-page

Copy after login

Since the blocks on the main page can change, we will move them separately to home/ui.

mkdir src/app/home/ui
mkdir src/app/home/ui/widgets
mkdir src/app/home/ui/widgets/lib
echo >src/app/home/ui/widgets/index.ts

Copy after login

Specify aliases:

"@baf/home/page": ["src/app/home/page/index.ts"], 
"@baf/home/ui/widgets": ["src/app/home/ui/widgets/index.ts"],

Copy after login

Consider ConnectComponent.
Let's run the command:

yarn ng g c Development of application pages

Copy after login

Marking:

<h2 baf-headline i18n="Connect|Title">We are always in touch</h2>
<baf-card>
  <div>
    <h3 baf-title i18n="Connect|Question">Have a question - write</h3>
    <p i18n="Connect|Desctiption">For example, if you need help choosing a ticket or paying</p>
    <p>
      <a baf-button bafmode="primary" bafsize="large" path i18n="Connect|Write">Write</a>
    </p>
  </div>
  <img ngsrc="/images/home/Development of application pages.svg"    style="max-width:90%"  style="max-width:90%" alt="Development of application pages">
</baf-card>

Copy after login

A few styles:

@use 'src/stylesheets/device' as device;

.baf-card {
  display: flex;
  flex-direction: column-reverse;

  img {
    max-width: 10rem;
    aspect-ratio: 1;
  }

  @include device.media-tablet-up() {
    flex-direction: row;
    justify-content: space-between;
  }
}

Copy after login

Logic:

import { NgOptimizedImage } from '@angular/common';
import { ChangeDetectionStrategy, Component } from '@angular/core';
import { RouterLink } from '@angular/router';

import { PathPipe, PATHS } from '@baf/core';
import { AnchorComponent } from '@baf/ui/buttons';
import { CardComponent } from '@baf/ui/cards';
import { HeadlineComponent } from '@baf/ui/headline';
import { TitleComponent } from '@baf/ui/title';

@Component({
  selector: 'baf-Development of application pages',
  standalone: true,
  imports: [NgOptimizedImage, TitleComponent, HeadlineComponent, CardComponent, AnchorComponent, RouterLink, PathPipe],
  templateUrl: './Development of application pages.component.html',
  styleUrl: './Development of application pages.component.scss',
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class ConnectComponent {
  readonly paths = PATHS;
}

Similarly for all other widgets.

As can be seen from the example, localization is used. For it to work you need to import @angular/localize.

yarn ng add @angular/localize

Copy after login

Or do everything by hand.

Add the package to package.json - @angular/localize.

Then we specify the typing in the main.ts and main.server.ts files:

/// <reference types="@angular/localize"></reference>

Copy after login

Expanding polyfills:

{
  "polyfills": ["zone.js", "@angular/localize/init"]
}

Copy after login

Change tsconfig.app.json and tsconfig.spec.json a little:

{
  "types": ["node", "@angular/localize"]
}

Copy after login

Display widgets on the main page:

<baf-container>
  <baf-promo></baf-promo>
  <router-outlet name="form"></router-outlet>
</baf-container>
<baf-section>
  <baf-container>
    <baf-must-buy></baf-must-buy>
    <baf-traveling></baf-traveling>
    <baf-convenient-with-us></baf-convenient-with-us>
    <baf-development of application pages></baf-development>
  </baf-container>
</baf-section>
<baf-section bafcolor="smoke">
  <baf-container>
    <baf-questions></baf-questions>
  </baf-container>
</baf-section>

Copy after login

Connect them:

import { ChangeDetectionStrategy, Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';

import {
  ConnectComponent,
  ConvenientWithUsComponent,
  MustBuyComponent,
  PromoComponent,
  QuestionsComponent,
  TravelingComponent,
} from '@baf/home/ui/widgets';
import { ContainerComponent } from '@baf/ui/container';
import { SectionComponent } from '@baf/ui/section';

@Component({
  selector: 'baf-home-page',
  standalone: true,
  imports: [
    RouterOutlet,
    ContainerComponent,
    SectionComponent,
    PromoComponent,
    MustBuyComponent,
    TravelingComponent,
    ConvenientWithUsComponent,
    ConnectComponent,
    QuestionsComponent,
  ],
  templateUrl: './home-page.component.html',
  styleUrl: './home-page.component.scss',
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class HomePageComponent {}

Copy after login

Now pages:

mkdir src/app/routes
echo >src/app/routes/home.routes.ts

Copy after login

Creating routes:

import type { Routes } from '@angular/router';

import { PATHS } from '@baf/core';

export const homeRoutes: Routes = [
  {
    path: PATHS.homeAvia,
    loadComponent: () => import('@baf/home/page').then((m) => m.HomePageComponent),
  },
  {
    path: PATHS.homeHotels,
    loadComponent: () => import('@baf/home/page').then((m) => m.HomePageComponent),
  },
  {
    path: PATHS.homeTours,
    loadComponent: () => import('@baf/home/page').then((m) => m.HomePageComponent),
  },
  {
    path: PATHS.homeRailways,
    loadComponent: () => import('@baf/home/page').then((m) => m.HomePageComponent),
  },
];

Copy after login

In app.routes.ts:

{
  path: '',
  loadChildren: () => import('./routes/home.routes').then((m) => m.homeRoutes),
}

Copy after login

Let's launch our application.

Errors

If the user follows a link that does not exist, then in default the router will throw an exception

Let's create a library where we will place basic HTTP errors: 403, 404 and 500.

mkdir src/app/errors

mkdir src/app/errors/not-found
mkdir src/app/errors/not-found/page
mkdir src/app/errors/not-found/page/lib
echo >src/app/errors/not-found/page/index.ts

mkdir src/app/errors/permission-denied
mkdir src/app/errors/permission-denied/page
mkdir src/app/errors/permission-denied/page/lib
echo >src/app/errors/permission-denied/page/index.ts

mkdir src/app/errors/server-error
mkdir src/app/errors/server-error/page
mkdir src/app/errors/server-error/page/lib
echo >src/app/errors/server-error/page/index.ts

Copy after login

All pages will be similar.

Create a template for not-found:

<baf-container bafalign="center">
  <h1 baf-headline>404</h1>
  <h3 baf-title i18n="Not Found|Title">Page not found</h3>
  <baf-errors-links></baf-errors-links>
</baf-container>

Copy after login

import { ChangeDetectionStrategy, Component } from '@angular/core';

import { ErrorsLinkComponent } from '@baf/errors/ui/links';
import { ContainerComponent } from '@baf/ui/container';
import { HeadlineComponent } from '@baf/ui/headline';
import { TitleComponent } from '@baf/ui/title';

@Component({
  selector: 'baf-not-found-page',
  standalone: true,
  imports: [ContainerComponent, HeadlineComponent, TitleComponent, ErrorsLinkComponent],
  templateUrl: './not-found-page.component.html',
  styleUrls: ['./not-found-page.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class NotFoundPageComponent {}

Copy after login

Add a common component with links:

mkdir src/app/errors/ui
mkdir src/app/errors/ui/lib
echo >src/app/errors/ui/index.ts

Copy after login

Run the command:

yarn ng g c errors-link

Copy after login

Move errors-link to src/app/errors/ui/lib.

<p i18n="Not Found|Perhaps you were looking for pages">Perhaps you were looking for pages</p>
<baf-nav></baf-nav>

Copy after login

import { ChangeDetectionStrategy, Component } from '@angular/core';

import type { NavigationLink } from '@baf/core';
import { PATHS } from '@baf/core';
import { NavComponent } from '@baf/ui/nav';

@Component({
  selector: 'baf-errors-links',
  standalone: true,
  imports: [NavComponent],
  templateUrl: './errors-link.component.html',
  styleUrls: ['./errors-link.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class ErrorsLinkComponent {
  readonly links: NavigationLink[] = [
    {
      route: PATHS.home,
      label: 'home',
    },
    {
      route: PATHS.documents,
      label: 'Documents',
    },
  ];
}

Copy after login

Let's define the paths to errors errors.routes.ts:

import type { Routes } from '@angular/router';

import { PATHS } from '@baf/core';

export const errorsRoutes: Routes = [
  {
    path: PATHS.permissionDenied,
    title: 'Permission Denied',
    loadComponent: () => import('@baf/errors/permission-denied/page').then((m) => m.PermissionDeniedPageComponent),
  },
  {
    path: PATHS.serverError,
    title: 'Internal Server Error',
    loadComponent: () => import('@baf/errors/server-error/page').then((m) => m.ServerErrorPageComponent),
  },
  {
    path: '**',
    title: 'Page not found',
    loadComponent: () => import('@baf/errors/not-found/page').then((m) => m.NotFoundPageComponent),
  },
];

Copy after login

Connect in app.routes.ts:

export const routes: Routes = [
  {
    path: '',
    loadComponent: () => import('@baf/ui/layout').then((m) => m.LayoutComponent),
    children: [
      //…
      {
        path: '',
        loadChildren: () => import('./routes/errors.routes').then((m) => m.errorsRoutes),
      },
    ],
  },
];

Section under development

Let's add a technical page that will be used as a placeholder.

mkdir src/app/development
mkdir src/app/development/page
mkdir src/app/development/page/lib
echo >src/app/development/page/index.ts

Copy after login

Add the component:

<baf-container>
  <h1 baf-headline i18n="Development Page|Title">Page is under construction</h1>
  <p i18n="Development Page|Description">
    This section is currently under development and will be available soon. We are working diligently to bring you new and exciting content,
    packed with features and improvements to enhance your experience. Please check back later for updates. We appreciate your patience and

Specify the routes in documents.routes.ts:

import type { Routes } from '@angular/router';

import { PATHS } from '@baf/core';

export const documentsRoutes: Routes = [
  {
    path: PATHS.rules,
    title: $localize`:Documents Rules:Rules for using the site`,
    loadComponent: () => import('@baf/development/page').then((m) => m.DevelopmentPageComponent),
  },
  {
    path: PATHS.terms,
    title: $localize`:Documents Terms:Conditions for participation in the program`,
    loadComponent: () => import('@baf/development/page').then((m) => m.DevelopmentPageComponent),

  {
    path: PATHS.documents,
    title: $localize`:Documents All:Documents`,
    loadComponent: () => import('@baf/development/page').then((m) => m.DevelopmentPageComponent),
