1. Web site rendering mode ---- rendering server and client rendering
1.1 server-side rendering (rendering backend SSR)
The case of the back-end rendering HTML, the browser will be received directly into the final after a string of HTML server computing presented to the user, calculated here is server parsed template file is stored in the server to complete, in this case , the browser only the HTML parsing, display, and manipulation by the display system of the operating system calls the image contents represented by the HTML displayed to the user on a display.
Benefits: less time-consuming front-end (front end only responsible html on display), which will help SEO
Disadvantages: large amount of network traffic, occupancy (part, a small part) server computing resources, response out of the amount of data will be (a little) big point, changed the front-end templates and interactive style of what was to follow the same linkage modifications
1.2 client rendering (front-end rendering CSR) ------ SPA --- single-page application
Rendering refers to the front-end browser will get some information from the back-end, such information may angularjs template files about, or JSON data interchange format and other packaged data, and even direct valid HTML string. These forms are not important, it is important that the arrangement of the information form the final tissue-readable HTML string is done by the browser, after forming a HTML string, and then displayed.
Benefits: a small amount of network traffic data (reduces the pressure on the server)
Disadvantages: front-end time-consuming, is not conducive to SEO
--- seo issues and problems first screen 2. The front-end rendering encountered
SEO is well understood. Because traditional search engine will crawl data from HTML, leading to the front page rendering can not be crawled. SPA commonly used front-end rendering all JS whole package will not be ignored is the file is too large, resulting in a long wait before rendering. Especially when the speed difference, allowing users to wait for the end of black and white is not a good experience.
2.1 front-end rendering SEO solve problems
In recent years, along with the rise of the front frame of the SPA; caused by the separation of the front and rear ends of SEO issues, I believe that each front-end siege Lions have encountered. Here is an example to say Vue solve SEO methods;
2.1.1 view ------ SSR
First vue2.x directly provide a complete service to build Vue side rendering. Vue.js is a framework for building client applications. By default, Vue assembly may be output in the browser, and operation for generating a DOM DOM. However, it is also possible to render the same component as the server-side HTML string, send them directly to the browser, the application will still mark the most "mixed" for the client fully interactive.
Rendering Vue.js server applications can also be considered a "homogeneous" or "universal" because most of the application's code can be run on the server and the client.
2.1.2 shock ------ Nuxt.js
Application from scratch to build a server-side rendering is quite complex. Fortunately Nuxt.js makes it all very simple. Nuxt Vue is based on a higher level of ecological framework, provides an extremely convenient development experience Vue end application services rendered. Cool is that you can even use it as a static station generator. Recommended attempt.
Nuxt.js is to create a Universal Vue.js application framework.
Its main scope is to render the UI, while the abstract client / server distribution.
Our goal is to create a framework flexible enough so that you can be used as the main library project or the current project-based Node.js is.
Nuxt.js pre-set enables developers Vue.js application server more enjoyable for all configurations.
In addition, we also offer another option called nuxt generate the deployment. It will build a static application Vue.js generated. We believe that this choice could be the next important step in the development of Microsoft's Web services applications.
As a framework, Nuxt.js offers many features that help you develop between the client and server side, such as asynchronous data, middleware and layout.
