Overview of Vue.js 3 CRUD example

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.js 3 CRUD Application.

– Create a Tutorial:

– Retrieve all Tutorials:

– Click on Edit button to update a Tutorial:

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 3 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 App.

Vue.js 3 Component Diagram with Vue Router & Axios

– The App component is a container with router-view. It has navbar that links to routes paths.

– TutorialsList component gets and displays Tutorials. – Tutorial 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 3
vue-router 4
axios 0.21.1
bootstrap 4

Project Structure

Let me explain it briefly.

– package.json contains 4 main modules: vue, vue-router, axios, bootstrap. – There are 3 components: TutorialsList, Tutorial, AddTutorial. – router.js defines routes for each component. – http-common.js 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 3 Project

Open cmd at the folder you want to save Project folder, run command: vue create vue-3-crud

You will see some options, choose Default ([Vue 3] babel, eslint). After the process is done. We create new folders and files like the following tree:

public

src

components

AddTutorial.vue

Tutorial.vue

TutorialsList.vue

services

TutorialDataService.js

App.vue

main.js

package.json

Add Bootstrap to Vue 3 CRUD example

Run command: npm install bootstrap jquery popper.js.

Open src/main.js and import Bootstrap as following-

import { createApp } from 'vue'
import App from './App.vue'
import 'bootstrap'
import 'bootstrap/dist/css/bootstrap.min.css'
...

Add Vue Router to Vue 3 CRUD example

– Run the command: npm install vue-router@4.

– In src folder, create router.js and define Router as following code:

import { createWebHistory, createRouter } from "vue-router";

const routes =  [
  {
    path: "/",
    alias: "/tutorials",
    name: "tutorials",
    component: () => import("./components/TutorialsList")
  },
  {
    path: "/tutorials/:id",
    name: "tutorial-details",
    component: () => import("./components/Tutorial")
  },
  {
    path: "/add",
    name: "add",
    component: () => import("./components/AddTutorial")
  }
];

const router = createRouter({
  history: createWebHistory(),
  routes,
});

export default router;

We create the routes as an array, each route has:

path: the URL path where this route can be found.
name: optional name to use when we link to this route.
component: component to load when this route is called.

We also use createWebHistory to switch from using hash to history mode inside the browser, using the HTML5 history API.

– Open src/main.js and import the router in our application:

...
import router from './router'

createApp(App).use(router).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">
      <router-link to="/" class="navbar-brand">bezKoder</router-link>
      <div class="navbar-nav mr-auto">
        <li class="nav-item">
          <router-link to="/tutorials" class="nav-link">Tutorials</router-link>
        </li>
        <li class="nav-item">
          <router-link to="/add" class="nav-link">Add</router-link>
        </li>
      </div>
    </nav>

    <div class="container mt-3">
      <router-view />
    </div>
  </div>
</template>

<script>
export default {
  name: "app"
};
</script>

Initialize Axios for Vue 3 CRUD HTTP Client

Now we’re gonna install axios with command: npm install axios. Then, under src folder, we create http-common.js 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.js

import http from "../http-common";

class TutorialDataService {
  getAll() {
    return http.get("/tutorials");
  }

  get(id) {
    return http.get(`/tutorials/${id}`);
  }

  create(data) {
    return http.post("/tutorials", data);
  }

  update(id, data) {
    return http.put(`/tutorials/${id}`, data);
  }

  delete(id) {
    return http.delete(`/tutorials/${id}`);
  }

  deleteAll() {
    return http.delete(`/tutorials`);
  }

  findByTitle(title) {
    return http.get(`/tutorials?title=${title}`);
  }
}

export default new TutorialDataService();

Create Vue 3 Components

As I’ve said before, we have 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>
import TutorialDataService from "../services/TutorialDataService";

export default {
  name: "add-tutorial",
  data() {
    return {
      tutorial: {
        id: null,
        title: "",
        description: "",
        published: false
      },
      submitted: false
    };
  },
  methods: {
    saveTutorial() {
      var 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 = {};
    }
  }
};
</script>

<style>
.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">
      <div class="input-group mb-3">
        <input type="text" class="form-control" placeholder="Search by title"
          v-model="title"/>
        <div class="input-group-append">
          <button class="btn btn-outline-secondary" type="button"
            @click="searchTitle"
          >
            Search
          </button>
        </div>
      </div>
    </div>
    <div class="col-md-6">
      <h4>Tutorials List</h4>
      <ul class="list-group">
        <li class="list-group-item"
          :class="{ active: index == currentIndex }"
          v-for="(tutorial, index) in tutorials"
          :key="index"
          @click="setActiveTutorial(tutorial, index)"
        >
          {{ tutorial.title }}
        </li>
      </ul>

      <button class="m-3 btn btn-sm btn-danger" @click="removeAllTutorials">
        Remove All
      </button>
    </div>
    <div class="col-md-6">
      <div v-if="currentTutorial">
        <h4>Tutorial</h4>
        <div>
          <label><strong>Title:</strong></label> {{ currentTutorial.title }}
        </div>
        <div>
          <label><strong>Description:</strong></label> {{ currentTutorial.description }}
        </div>
        <div>
          <label><strong>Status:</strong></label> {{ currentTutorial.published ? "Published" : "Pending" }}
        </div>

        <router-link :to="'/tutorials/' + currentTutorial.id" class="badge badge-warning">Edit</router-link>
      </div>
      <div v-else>
        <br />
        <p>Please click on a Tutorial...</p>
      </div>
    </div>
  </div>
</template>

<script>
import TutorialDataService from "../services/TutorialDataService";

export default {
  name: "tutorials-list",
  data() {
    return {
      tutorials: [],
      currentTutorial: null,
      currentIndex: -1,
      title: ""
    };
  },
  methods: {
    retrieveTutorials() {
      TutorialDataService.getAll()
        .then(response => {
          this.tutorials = response.data;
          console.log(response.data);
        })
        .catch(e => {
          console.log(e);
        });
    },

    refreshList() {
      this.retrieveTutorials();
      this.currentTutorial = null;
      this.currentIndex = -1;
    },

    setActiveTutorial(tutorial, index) {
      this.currentTutorial = tutorial;
      this.currentIndex = tutorial ? index : -1;
    },

    removeAllTutorials() {
      TutorialDataService.deleteAll()
        .then(response => {
          console.log(response.data);
          this.refreshList();
        })
        .catch(e => {
          console.log(e);
        });
    },
    
    searchTitle() {
      TutorialDataService.findByTitle(this.title)
        .then(response => {
          this.tutorials = response.data;
          this.setActiveTutorial(null);
          console.log(response.data);
        })
        .catch(e => {
          console.log(e);
        });
    }
  },
  mounted() {
    this.retrieveTutorials();
  }
};
</script>

<style>
.list {
  text-align: left;
  max-width: 750px;
  margin: auto;
}
</style>

If you click on Edit button of any Tutorial, the app will direct you to Tutorial page with url: /tutorials/:tutorialId.

You can add Pagination to this Component, just follow instruction in the post: Vue Pagination with Axios and API (Server Side pagination) example

Item details Component

For getting data & update, delete the Tutorial, this component will use 3 TutorialDataService methods:

get()
update()
delete()

components/Tutorial.vue

<template>
  <div v-if="currentTutorial" class="edit-form">
    <h4>Tutorial</h4>
    <form>
      <div class="form-group">
        <label for="title">Title</label>
        <input type="text" class="form-control" id="title"
          v-model="currentTutorial.title"
        />
      </div>
      <div class="form-group">
        <label for="description">Description</label>
        <input type="text" class="form-control" id="description"
          v-model="currentTutorial.description"
        />
      </div>

      <div class="form-group">
        <label><strong>Status:</strong></label>
        {{ currentTutorial.published ? "Published" : "Pending" }}
      </div>
    </form>

    <button class="badge badge-primary mr-2"
      v-if="currentTutorial.published"
      @click="updatePublished(false)"
    >
      UnPublish
    </button>
    <button v-else class="badge badge-primary mr-2"

    <button type="submit" class="badge badge-success"
      @click="updateTutorial"
    >
      Update

    <p>{{ message }}</p>
  </div>

  <div v-else>
    <br />
    <p>Please click on a Tutorial...</p>
  </div>
</template>

<script>
import TutorialDataService from "../services/TutorialDataService";

export default {
  name: "tutorial",
  data() {
    return {
      currentTutorial: null,
      message: ''
    };
  },
  methods: {
    getTutorial(id) {
      TutorialDataService.get(id)
        .then(response => {
          this.currentTutorial = response.data;
          console.log(response.data);
        })
        .catch(e => {
          console.log(e);
        });
    },

    updatePublished(status) {
      var data = {
        id: this.currentTutorial.id,
        title: this.currentTutorial.title,
        description: this.currentTutorial.description,
        published: status
      };

      TutorialDataService.update(this.currentTutorial.id, data)
        .then(response => {
          console.log(response.data);
          this.currentTutorial.published = status;
          this.message = 'The status was updated successfully!';
        })
        .catch(e => {
          console.log(e);
        });
    },

    updateTutorial() {
      TutorialDataService.update(this.currentTutorial.id, this.currentTutorial)
        .then(response => {
          console.log(response.data);
          this.message = 'The tutorial was updated successfully!';
        })
        .catch(e => {
          console.log(e);
        });
    },

    deleteTutorial() {
      TutorialDataService.delete(this.currentTutorial.id)
        .then(response => {
          console.log(response.data);
          this.$router.push({ name: "tutorials" });
        })
        .catch(e => {
          console.log(e);
        });
    }
  },
  mounted() {
    this.message = '';
    this.getTutorial(this.$route.params.id);
  }
};
</script>

<style>
.edit-form {
  max-width: 300px;
  margin: auto;
}
</style>

Configure Port for Vue 3 CRUD example

Because most of HTTP Server use CORS configuration that accepts resource sharing restricted 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.js 3 CRUD example

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.js 3 CRUD example successfully with Axios and Vue Router. Now we can consume REST APIs, display and modify data in a clean way. I hope you apply it in your project at ease.

There is Typescript version at: Vue 3 Typescript example with Axios: Build CRUD App

Or you can add Pagination Component: Vue Pagination with Axios and API example

Or Vuetify version: Vuetify data-table example with a CRUD App | v-data-table

Happy learning, see you again!
