The purpose of this article is to share with you what spa means in vue. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In vue, the full name of spa is "single-page application", which means "single page application" in Chinese. It is an application with only one Web page, which is a Web application that loads a single HTML page and dynamically updates the page when the user interacts with the application.

The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.

SPA in Vue

SPA (single-page application, single-page application). An application with only one Web page is a Web application that loads a single HTML page and dynamically updates that page as the user interacts with the application.

Load the corresponding HTML,JavaScript and CSS when the Web page is initialized. Once the page is loaded, SPA will not reload or jump the page because of the user's operation; instead, it uses the routing mechanism to achieve the change of HTML content, and the interaction between UI and users to avoid page reloading.

Differences from traditional multi-page programs:

Traditional multi-page program: every time you request the server to return a complete page

Single-page application: only the first time the page is loaded, and each subsequent request is just to get the necessary data. Then, the data obtained by parsing the js in the page is displayed on the page.

Advantages:

1 reduces the request volume, speeds up the page response speed, and reduces the pressure on the server

2 better user experience, let users feel the fluency of native app in web app

Disadvantages:

Because the technology uses ajax, the page is not good for SEO, but it can be avoided by other technologies.

(SEO principle: spiders of search engines only recognize general hyperlinks of href, but not JavaScript code. They will climb in when they encounter general hyperlinks, but will not climb in when they encounter JavaScript. That is, the search engine cannot catch the content dynamically loaded by AJAX. )

1) Server rendering 2) static page (specially for crawlers)

Main technical points:

1 ajax

2 use of anchor points (_ window.location.hash #)

3 hashchange event

The idea of realization is:

Listen for events with changing anchor values and request corresponding data according to different anchor values

1 the anchor point (#) was originally used to jump inside the page to locate and display the corresponding content

2 in SPA, anchors are used as identifiers to request different resources, request data, and display content
