How to make a simple project with vue

With the rapid development of the Vue framework, more and more people are beginning to use it to build front-end projects. Vue is easy to learn and use, flexible, efficient, and reusable, so many new front-end projects are now developed using Vue. So, how to implement a simple project with Vue? This article will answer them one by one for you.

Step one: Set up the Vue environment

Before you start using Vue, you need to install the Vue running environment, including Vue CLI and Node.js. Vue CLI is a command line tool for Vue. It allows you to create a new Vue project and manage more complex projects through the Vue UI interface. Node.js is a necessary dependency of Vue CLI, which allows the project to run in the browser.

After installing Vue CLI and Node.js, you can easily create a new Vue project. Using the Vue CLI, you can create a brand new Vue project with the following command:

vue create my-project
cd my-project
npm run serve

This process may take a while to complete, but once it is complete, you can run the project and view it. Enter http://localhost:8080/ in the browser to access the running project.

Step 2: Design Vue components

In Vue, you need to design multiple components to realize the entire project function. Components can be understood as various elements displayed on a web page, such as buttons, text boxes, pictures, etc. Through the design and combination of components, a complete project can be built.

When designing a component, you need to consider the following points:

1. Function of the component: What functions are to be achieved? Such as login, registration, information upload, etc.
2. Component style: What style does the component need to have? Color, font, size, borders, etc.
3. Component data: What is the data required by the component? How to get data from parent component? How to pass data to child component?
4. Events of components: What events does the component need to respond to? How to handle these events?

According to the above design ideas, the required components can be gradually built.

Step 3: Build Vue routing

In Vue, the routing of the page is managed by Vue Router. Through Vue Router, you can define multiple routing rules and map the routing rules to the corresponding components. Vue Router can easily push and jump between different pages.

To use Vue Router, you need to install it first:

npm install vue-router --save

After installation, create the router directory in the project and create an index.js file in which routing rules are defined. :

import Vue from 'vue';
import Router from 'vue-router';
import Home from './views/Home.vue';
import About from './views/About.vue';

Vue.use(Router);

export default new Router({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home,
    },
    {
      path: '/about',
      name: 'about',
      component: About,
    },
  ],
});

In the above code, two routing rules are defined, one is the homepage path "/", and the other is the about page path "/about". Each routing rule is mapped to a Vue component, which has been defined previously.

Step 4: Data Management

In Vue, you need to consider data management. Data can be managed through Vuex, a state management pattern developed specifically for Vue.js applications. It has a global store object that manages the state of the entire application. Vuex provides some special APIs to modify the store, which allows data in other components to be kept in sync.

To use Vuex, you need to install it first:

npm install vuex --save

Then, create the store directory in the project and create an index.js file in which the state management code is defined:

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

export default new Vuex.Store({
  state: {
    count: 0,
  },
  mutations: {
    increment(state) {
      state.count += 1;
    },
  },
  actions: {
    incrementAsync({ commit }) {
      setTimeout(() => {
        commit('increment');
      }, 1000);
    },
  },
  modules: {},
});

In the above code, a store object is defined, containing three attributes: state, mutations, and actions. The state attribute is used to store state, the mutations attribute contains some methods for modifying the state, and the actions attribute contains some asynchronous operations.

Step 5: API request

In Vue, you need to interact with the backend data. RESTful API calls can be implemented in Vue through Axios. Axios is a Promise-based HTTP library that can interact with browsers and the Node.js platform.

To use Axios, you need to install it first:

npm install axios --save

Then, inside the Vue component, you can make data requests by calling Axios:

import axios from 'axios';

methods: {
  fetchData() {
    axios.get('/api/data').then((res) => {
      this.data = res.data;
    });
  },
},

In the above code, use Axios sends a GET request and saves the obtained data in the component's data attribute.

Step Six: Publish and Deploy

When your Vue project is developed, you need to publish and deploy it to the server. Publishing and deployment are divided into two processes: first package the project, and then deploy the packaged files to the server.

To package the project, you can run the following command:

npm run build

This will generate a packaged file in the dist directory. Then, you can deploy the files in the dist directory to the server.

Conclusion

The above are the steps on how to use Vue to implement a simple project. Through the above steps, you can learn how to use Vue to design components, manage routing, manage status, request APIs, and finally package and deploy the project. If you don’t know enough about Vue, you can continue to learn more and master more advanced technologies.
