Let us create a web app using the vue.js framework. We will create a simple app for working with a rest api. The api endpoint is /tenants. Users can create, update, delete, get tenants.
Sure, let's get started! Here are the steps to create a web app using Vue.js for working with a REST API:
- Create a new Vue.js project using the Vue CLI. You can do this by running the following command in your terminal:
vue create my-app
This will create a new Vue.js project called "my-app".
- Install the Axios library, which we will use for making HTTP requests to the REST API. You can install it by running the following command in your terminal:
npm install axios
- Create a new component for displaying the list of tenants. You can do this by creating a new file called "TenantList.vue" in the "src/components" directory, and adding the following code:
<template>
<div>
<h2>Tenants</h2>
<ul>
<li v-for="tenant in tenants" :key="tenant.id">{{ tenant.name }}</li>
</ul>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
tenants: []
}
},
mounted() {
axios.get('/tenants')
.then(response => {
this.tenants = response.data;
})
.catch(error => {
console.log(error);
});
}
}
</script>This component fetches the list of tenants from the REST API and displays them in a list.
- Create a new component for adding new tenants. You can do this by creating a new file called "AddTenant.vue" in the "src/components" directory, and adding the following code:
<template>
<div>
<h2>Add Tenant</h2>
<form @submit.prevent="addTenant">
<div>
<label for="name">Name:</label>
<input type="text" id="name" v-model="name">
</div>
<button type="submit">Add</button>
</form>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
name: ''
}
},
methods: {
addTenant() {
axios.post('/tenants', { name: this.name })
.then(response => {
this.$emit('tenant-added', response.data);
this.name = '';
})
.catch(error => {
console.log(error);
});
}
}
}
</script>This component allows users to add new tenants to the REST API by filling out a form.
- Create a new component for updating existing tenants. You can do this by creating a new file called "EditTenant.vue" in the "src/components" directory, and adding the following code:
<template>
<div>
<h2>Edit Tenant</h2>
<form @submit.prevent="updateTenant">
<div>
<label for="name">Name:</label>
<input type="text" id="name" v-model="name">
</div>
<button type="submit">Update</button>
</form>
</div>
</template>
<script>
import axios from 'axios';
export default {
props: ['tenant'],
data() {
return {
name: this.tenant.name
}
},
methods: {
updateTenant() {
axios.put(`/tenants/${this.tenant.id}`, { name: this.name })
.then(response => {
this.$emit('tenant-updated', response.data);
})
.catch(error => {
console.logWhen the user starts the app the app should list all tenants, with the possibility to add a new tenant. When clicking on a tenant in thw list user can edit tenant
Sure, here's how you can update the previous code to allow users to view and edit existing tenants:
- Update the TenantList.vue component to include links for editing each tenant. You can do this by replacing the li element with the following code:
<li v-for="tenant in tenants" :key="tenant.id">
<router-link :to="{ name: 'edit-tenant', params: { id: tenant.id } }">{{ tenant.name }}</router-link>
</li>This will create a link for each tenant that takes the user to the EditTenant component with the id parameter set to the ID of the tenant.
- Update the App.vue component to include the router-view element, which will display the appropriate component based on the current URL. You can do this by replacing the contents of the template element with the following code:
<template>
<div id="app">
<h1>Tenant Management</h1>
<router-link to="/add-tenant">Add Tenant</router-link>
<router-view></router-view>
</div>
</template>This will create a link for adding a new tenant and display the appropriate component based on the current URL.
- Update the main.js file to configure the Vue Router and define the routes for the TenantList, AddTenant, and EditTenant components. You can do this by replacing the contents of the file with the following code:
import Vue from 'vue';
import App from './App.vue';
import VueRouter from 'vue-router';
import TenantList from './components/TenantList.vue';
import AddTenant from './components/AddTenant.vue';
import EditTenant from './components/EditTenant.vue';
Vue.use(VueRouter);
const routes = [
{ path: '/', component: TenantList },
{ path: '/add-tenant', component: AddTenant },
{ path: '/edit-tenant/:id', name: 'edit-tenant', component: EditTenant }
];
const router = new VueRouter({
routes
});
new Vue({
router,
render: h => h(App),
}).$mount('#app');This will configure the Vue Router and define the routes for the TenantList, AddTenant, and EditTenant components.
- Update the EditTenant.vue component to fetch the details of the tenant with the specified ID and display them in the form. You can do this by replacing the contents of the script element with the following code:
<script>
import axios from 'axios';
export default {
props: ['id'],
data() {
return {
name: ''
}
},
mounted() {
axios.get(`/tenants/${this.id}`)
.then(response => {
this.name = response.data.name;
})
.catch(error => {
console.log(error);
});
},
methods: {
updateTenant() {
axios.put(`/tenants/${this.id}`, { name: this.name })
.then(response => {
this.$emit('tenant-updated', response.data);
})
.catch(error => {
console.log(error);
});
}
}
}
</script>This will fetch the details of the tenant with the specified ID and display them in the form.
And that's it! With these changes, your Vue.js app should list all tenants when the user starts the app, with the possibility to add a new tenant, and when clicking on a tenant in the list, the user can view and edit the tenant details.
We also need authentication. I want to use AzureAD for OIDC authentication
Sure, here's how you can add authentication using AzureAD for OIDC authentication:
- Register your application with Azure AD. You can do this by following the instructions in the Microsoft Azure documentation.
- Install the vue-oidc-client library, which provides a wrapper around the OIDC client library for Vue.js. You can do this by running the following command in your terminal:
npm install vue-oidc-client
- Configure the vue-oidc-client library in your main.js file. You can do this by adding the following code to the file:
import Vue from 'vue';
import App from './App.vue';
import VueRouter from 'vue-router';
import TenantList from './components/TenantList.vue';
import AddTenant from './components/AddTenant.vue';
import EditTenant from './components/EditTenant.vue';
import { createOidcAuth } from 'vue-oidc-client';
Vue.use(VueRouter);
const routes = [
{ path: '/', component: TenantList },
{ path: '/add-tenant', component: AddTenant },
{ path: '/edit-tenant/:id', name: 'edit-tenant', component: EditTenant }
];
const router = new VueRouter({
routes
});
const oidcAuth = createOidcAuth('azure-ad', {
authority: 'https://login.microsoftonline.com/{tenant-id}/',
clientId: '{client-id}',
redirectUri: 'http://localhost:8080/oidc-callback',
responseType: 'code',
scope: 'openid profile',
automaticSilentRenew: true,
extraQueryParams: {
resource: '{resource-id}'
},
storage: {
getItem: key => localStorage.getItem(key),
setItem: (key, value) => localStorage.setItem(key, value),
removeItem: key => localStorage.removeItem(key)
}
});
Vue.prototype.$oidcAuth = oidcAuth;
oidcAuth.redirectCallback().then(() => {
new Vue({
router,
render: h => h(App),
}).$mount('#app');
});This will configure the vue-oidc-client library with the appropriate settings for your Azure AD application.
- Modify your TenantList.vue component to require authentication before showing the list of tenants. You can do this by replacing the contents of the script element with the following code:
<script>
export default {
data() {
return {
tenants: []
}
},
mounted() {
this.$oidcAuth.isAuthenticated().then(isAuthenticated => {
if (isAuthenticated) {
axios.get('/tenants')
.then(response => {
this.tenants = response.data;
})
.catch(error => {
console.log(error);
});
} else {
this.$oidcAuth.signIn();
}
});
}
}
</script>This will check if the user is authenticated before fetching the list of tenants. If the user is not authenticated, it will redirect them to the Azure AD login page.
- Modify your AddTenant.vue and EditTenant.vue components to require authentication before allowing users to add or edit tenants. You can do this by adding the following code to the mounted method of each component:
this.$oidcAuth.isAuthenticated().then(isAuthenticated => {
if (!isAuthenticated) {
this.$oidcAuth.signIn();
}
});This will check if the user is authenticated before allowing them to add or edit tenants. If
Now i want thw app to have a toolbar on top with standard items like login buttin
Sure, here's how you can add a toolbar with a login button to your app:
- Add a new component for the toolbar. You can do this by creating a new file called "Toolbar.vue" in the "src/components" directory, and adding the following code:
<template>
<div id="toolbar">
<router-link to="/">Tenant Management</router-link>
<div v-if="$oidcAuth.isAuthenticated()">
<span>{{ $oidcAuth.user.profile.name }}</span>
<button @click="$oidcAuth.signOut()">Logout</button>
</div>
<div v-else>
<button @click="$oidcAuth.signIn()">Login</button>
</div>
</div>
</template>
<script>
export default {
name: 'Toolbar'
}
</script>
<style scoped>
#toolbar {
display: flex;
justify-content: space-between;
align-items: center;
padding: 8px;
background-color: #0078D7;
color: white;
}
#toolbar a {
color: white;
text-decoration: none;
}
</style>This component displays a toolbar with a link to the Tenant Management page, and a login button if the user is not authenticated or a logout button if the user is authenticated.
- Update the App.vue component to include the Toolbar component. You can do this by replacing the contents of the template element with the following code:
<template>
<div id="app">
<Toolbar />
<router-view />
</div>
</template>This will add the Toolbar component to the top of the app.
- Update the styles of your app to make room for the toolbar. You can do this by adding the following code to the style section of your App.vue component:
#app {
margin-top: 64px;
}This will add a top margin to the app to make room for the toolbar.
And that's it! With these changes, your Vue.js app should have a toolbar on top with standard items like a login button.
Redesign layout to use vuetify with a constrained wireframe template
Sure, here's how you can redesign your app layout to use Vuetify with a constrained wireframe template:
- Install Vuetify and the Material Design Icons library. You can do this by running the following commands in your terminal:
npm install vuetify
npm install @mdi/font
- Update the main.js file to import Vuetify and configure it with the appropriate settings. You can do this by replacing the contents of the file with the following code:
import Vue from 'vue';
import App from './App.vue';
import VueRouter from 'vue-router';
import TenantList from './components/TenantList.vue';
import AddTenant from './components/AddTenant.vue';
import EditTenant from './components/EditTenant.vue';
import { createOidcAuth } from 'vue-oidc-client';
import Vuetify from 'vuetify';
import '@mdi/font/css/materialdesignicons.css';
Vue.use(Vuetify);
const vuetify = new Vuetify({
icons: {
iconfont: 'mdi'
},
theme: {
themes: {
light: {
primary: '#0078D7'
}
}
}
});
Vue.use(VueRouter);
const routes = [
{ path: '/', component: TenantList },
{ path: '/add-tenant', component: AddTenant },
{ path: '/edit-tenant/:id', name: 'edit-tenant', component: EditTenant }
];
const router = new VueRouter({
routes
});
const oidcAuth = createOidcAuth('azure-ad', {
authority: 'https://login.microsoftonline.com/{tenant-id}/',
clientId: '{client-id}',
redirectUri: 'http://localhost:8080/oidc-callback',
responseType: 'code',
scope: 'openid profile',
automaticSilentRenew: true,
extraQueryParams: {
resource: '{resource-id}'
},
storage: {
getItem: key => localStorage.getItem(key),
setItem: (key, value) => localStorage.setItem(key, value),
removeItem: key => localStorage.removeItem(key)
}
});
Vue.prototype.$oidcAuth = oidcAuth;
oidcAuth.redirectCallback().then(() => {
new Vue({
router,
vuetify,
render: h => h(App),
}).$mount('#app');
});This will import Vuetify and configure it with the appropriate settings.
- Replace the contents of your App.vue component with the following code:
<template>
<v-app>
<Toolbar />
<v-main>
<v-container fluid>
<router-view />
</v-container>
</v-main>
</v-app>
</template>
<script>
import Toolbar from './components/Toolbar.vue';
export default {
name: 'App',
components: {
Toolbar
}
}
</script>
<style>
html {
height: 100%;
}
body {
height: 100%;
}
#app {
height: 100%;
}
</style>This will use the v-app, v-main, and v-container components from Vuetify to create a layout with a toolbar at the top and a main content area below.
- Update your Toolbar.vue component to use Vuetify components instead of plain HTML elements. You can do this by replacing the contents of the template element with the following code:
<template>
<v-app-bar app color="primary" dark>
<v-toolbar-title>
<router-link to="/">Tenant Management</router-link>npm install
npm run serve
npm run build
npm run lint
