Overview of Vue Typescript CRUD Application
We will build a Vue.js front-end Tutorial Application in that:
- Each Tutorial has id, title, description, published status.
- We can create, retrieve, update, delete Tutorials.
- There is a Search bar for finding Tutorials by title.
Here are screenshots of our Vue Typescript CRUD Application.
– Create an object:
– Retrieve all objects:
– Click on Edit button to update an object:
On this Page, you can:
- change status to Published using Publish button
- delete the Tutorial using Delete button
- update the Tutorial details with Update button
– Search Tutorials by title:
The introduction above is for Vue.js Client with assumption that we have a Server exporting REST APIs:
Methods | Urls | Actions |
---|---|---|
POST | /api/tutorials | create new Tutorial |
GET | /api/tutorials | retrieve all Tutorials |
GET | /api/tutorials/:id | retrieve a Tutorial by :id |
PUT | /api/tutorials/:id | update a Tutorial by :id |
DELETE | /api/tutorials/:id | delete a Tutorial by :id |
DELETE | /api/tutorials | delete all Tutorials |
GET | /api/tutorials?title=[keyword] | find all Tutorials which title contains keyword |
You can find step by step to build a Server like this in one of these posts:
– Express, Sequelize & MySQL
– Express, Sequelize & PostgreSQL
– Express, Sequelize & SQL Server
– Express & MongoDb
– Spring Boot & MySQL
– Spring Boot & PostgreSQL
– Spring Boot & MongoDB
– Spring Boot & SQL Server
– Spring Boot & H2
– Spring Boot & Cassandra
– Spring Boot & Oracle
– Python/Django & MySQL
– Python/Django & PostgreSQL
– Python/Django & MongoDB
All of them can work well with this Vue Typescript App.
Vue Typescript App Component Diagram
– The App
component is a container with router-view
. It has navbar that links to routes paths.
– TutorialsList
component gets and displays Tutorials.
– Tutorial
(TutorialDetails
) component has form for editing Tutorial’s details based on :id
.
– AddTutorial
component has form for submission new Tutorial.
– These Components call TutorialDataService
methods which use axios
to make HTTP requests and receive responses.
Technology
- vue: 2.6.11
- vue-router: 3.1.6
- axios: 0.19.2
- vue-class-component 7.2.3
- vue-property-decorator 8.4.1
Project Structure
Let me explain it briefly.
– package.json contains main modules: vue
, vue-router
, vue-class-component
, axios
.
– types/Tutorial.ts exports Tutorial
interface.
– There are 3 components: TutorialsList
, TutorialDetails
, AddTutorial
.
– router/index.ts defines routes for each component.
– http-common.ts initializes axios with HTTP base Url and headers.
– TutorialDataService
has methods for sending HTTP requests to the Apis.
– vue.config.js configures port for this Vue Client.
Setup Vue.js Typescript Project
Open cmd at the folder you want to save Project folder, run command:
vue create vue-typescript-crud
You will see some options, choose Manually select features.
Select the following options:
Then configure the project like this:
? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, TS
? Use class-style component syntax? Yes
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? Yes
? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? In package.json
? Save this as a preset for future projects? (y/N) No
After the process is done. We create new folders and files like the following tree:
public
index.html
src
components
AddTutorial.vue
TutorialDetails.vue
TutorialsList.vue
services
TutorialDataService.ts
types
Tutorial.ts
App.vue
main.ts
package.json
Open public/index.html, add bootstrap inside <head>
tag:
<!DOCTYPE html>
<html lang="en">
<head>
...
<title>Vue Typescript CRUD</title>
<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css" />
</head>
<body>
...
</body>
</html>
Add Vue Router to Vue Typescript App
– Run the command: npm install vue-router
.
– In src/router folder, create index.ts and define Router
as following code:
import Vue from "vue";
import VueRouter, { RouteConfig } from "vue-router";
Vue.use(VueRouter);
const routes: Array<RouteConfig> = [
{
path: "/",
alias: "/tutorials",
name: "tutorials",
component: () => import("../components/TutorialsList.vue")
},
{
path: "/tutorials/:id",
name: "tutorial-details",
component: () => import("../components/TutorialDetails.vue")
},
{
path: "/add",
name: "add",
component: () => import("../components/AddTutorial.vue")
}
];
const router = new VueRouter({
mode: "history",
base: process.env.BASE_URL,
routes
});
export default router;
– Open src/main.ts, then import router
:
import Vue from "vue";
import App from "./App.vue";
import router from "./router";
Vue.config.productionTip = false;
new Vue({
router,
render: h => h(App)
}).$mount("#app");
Let’s open src/App.vue, this App
component is the root container for our application, it will contain a navbar
.
<template>
<div id="app">
<nav class="navbar navbar-expand navbar-dark bg-dark">
<a href="#" class="navbar-brand">bezKoder</a>
<div class="navbar-nav mr-auto">
<li class="nav-item">
<a href="/tutorials" class="nav-link">Tutorials</a>
</li>
<li class="nav-item">
<a href="/add" class="nav-link">Add</a>
</li>
</div>
</nav>
<div class="container mt-3">
<router-view />
</div>
</div>
</template>
<script lang="ts">
import { Component, Vue } from "vue-property-decorator";
@Component
export default class App extends Vue {}
</script>
Initialize Axios for Vue Typescript CRUD HTTP Client
Let’s install axios with command: npm install axios
.
Then, under src folder, we create http-common.ts file like this:
import axios from "axios";
export default axios.create({
baseURL: "http://localhost:8080/api",
headers: {
"Content-type": "application/json"
}
});
Remember to change the baseURL
, it depends on REST APIs url that your Server configures.
For more details about ways to use Axios, please visit:
Axios request: Get/Post/Put/Delete example
Create Data Service
Our service will use axios from HTTP client above to send HTTP requests.
services/TutorialDataService.ts
import http from "../http-common";
class TutorialDataService {
getAll() {
return http.get("/tutorials");
}
get(id: string) {
return http.get(`/tutorials/${id}`);
}
create(data: any) {
return http.post("/tutorials", data);
}
update(id: string, data: any) {
return http.put(`/tutorials/${id}`, data);
}
delete(id: string) {
return http.delete(`/tutorials/${id}`);
}
deleteAll() {
return http.delete(`/tutorials`);
}
findByTitle(title: string) {
return http.get(`/tutorials?title=${title}`);
}
}
export default new TutorialDataService();
Create Tutorial interface
Open types/Tutorial.ts and define Tutorial
interface:
export default interface Tutorial {
id: null;
title: string;
description: string;
published: boolean;
}
Create Vue Components
As I’ve said before, there are 3 components corresponding to 3 routes defined in Vue Router.
Add item Component
This component has a Form to submit new Tutorial with 2 fields: title
& description
. It calls TutorialDataService.create()
method.
components/AddTutorial.vue
<template>
<div class="submit-form">
<div v-if="!submitted">
<div class="form-group">
<label for="title">Title</label>
<input
type="text"
class="form-control"
id="title"
required
v-model="tutorial.title"
name="title"
/>
</div>
<div class="form-group">
<label for="description">Description</label>
<input
class="form-control"
id="description"
required
v-model="tutorial.description"
name="description"
/>
</div>
<button @click="saveTutorial" class="btn btn-success">Submit</button>
</div>
<div v-else>
<h4>You submitted successfully!</h4>
<button class="btn btn-success" @click="newTutorial">Add</button>
</div>
</div>
</template>
<script lang="ts">
import { Component, Vue } from "vue-property-decorator";
import TutorialDataService from "@/services/TutorialDataService";
import Tutorial from "@/types/Tutorial";
@Component
export default class AddTutorial extends Vue {
private tutorial: Tutorial = {
id: null,
title: "",
description: "",
published: false,
};
private submitted: boolean = false;
saveTutorial() {
let data = {
title: this.tutorial.title,
description: this.tutorial.description,
};
TutorialDataService.create(data)
.then((response) => {
this.tutorial.id = response.data.id;
console.log(response.data);
this.submitted = true;
})
.catch((e) => {
console.log(e);
});
}
newTutorial() {
this.submitted = false;
this.tutorial = {} as Tutorial;
}
}
</script>
<style scoped>
.submit-form {
max-width: 300px;
margin: auto;
}
</style>
List of items Component
This component calls 3 TutorialDataService
methods:
getAll()
deleteAll()
findByTitle()
components/TutorialsList.vue
<template>
<div class="list row">
<div class="col-md-8">

If you click on Edit button of any Tutorial, the app will direct you to Tutorial page with url: /tutorials/:tutorialId
.
Item details Component
This component will use 3 TutorialDataService
methods for getting data & update, delete the Tutorial:
get()
update()
delete()

Configure Port for Vue Typescript CRUD App
Because most of HTTP Server use CORS configuration that accepts resource sharing retrictted to some sites or ports, so we also need to configure port for our App.
In project root folder, create vue.config.js file with following content:
module.exports = {
devServer: {
port: 8081
}
}
We’ve set our app running at port 8081
.
Run Vue Typescript App
You can run our App with command: npm run serve
.
If the process is successful, open Browser with Url: http://localhost:8081/
and check it.
This Vue Client will work well with following back-end Rest APIs:
– Express, Sequelize & MySQL
– Express, Sequelize & PostgreSQL
– Express, Sequelize & SQL Server
– Express & MongoDb
– Spring Boot & MySQL
– Spring Boot & PostgreSQL
– Spring Boot & MongoDB
– Spring Boot & SQL Server
– Spring Boot & H2
– Spring Boot & Cassandra
– Spring Boot & Oracle
– Python/Django & MySQL
– Python/Django & PostgreSQL
– Python/Django & MongoDB
Conclusion
Today we’ve built a Vue Typescript example – CRUD Application successfully with Vue Router, Axios, Bootstrap. Now we can consume REST APIs, display and modify data in a clean way. I hope you apply it in your project at ease.
