Let's talk about the access process of Vue project

With the development of front-end technology, more and more companies and developers choose to use the Vue framework to develop web applications. Vue is a lightweight but powerful JavaScript framework that draws on some features of Angular and some ideas of React, while also having its own advantages. In the development process of Vue, the access process is a very critical part. Below I will introduce you to the access process of the Vue project.

1. Construction of Vue project

First, we need to use the Vue CLI command line tool to create a Vue project. Vue CLI is an official command line tool that can quickly build Vue projects.

After installing Vue CLI, we can enter the following command to create a new project:

vue create my-project

The "my-project" here can be replaced with your own project name, and then follow the prompts to select With some options, you can quickly create a Vue project.

After the project is created, we can start the project through the following command:

npm run serve

In this way, we can access our Vue project by entering localhost:8080 in the browser.

2. Access process of Vue project

The access process of Vue project can be divided into two parts: client access and server access.

1. Client-side access

Client-side access refers to the process of users accessing the Vue project in the browser. The entry file of the Vue project is src/main.js, which will create a Vue instance and mount it to index.html, which is the starting point of the Vue project.

In Vue projects, we usually use vue-router to manage front-end routing. vue-router can help us jump between pages, and also supports advanced features such as dynamic routing and nested routing.

When the user enters a routing address in the browser, vue-router will find the Vue component corresponding to the route based on the routing rules in the configuration file and render it on the page. This process is usually asynchronous, so a loading effect is needed to prompt the user to wait.

2. Server access

Server access refers to the interaction process between the Vue project and the back-end server. In Vue projects, we usually use axios to send HTTP requests and process responses. Axios can be regarded as a proxy for HTTP requests.

When we send an HTTP request to the backend server, axios will forward the request to the backend server. The backend server will process the request based on the requested URL address, request parameters and other information, and return the processing results to axios. axios then parses the processing results into JSON format and returns it to the Vue component as response data.

3. Summary

Through the above introduction, we can see that the access process of the Vue project is a complex process that involves front-end routing, asynchronous requests and other aspects. Therefore, when designing a Vue project, you need to take these aspects into consideration and reasonably plan the relationship between Vue components and the way of data interaction with the back-end server. At the same time, you also need to be familiar with the use of tools such as Vue CLI and axios in order to better build a high-quality Vue project.
