This article mainly introduces "what is web front-end isomorphic rendering". In daily operation, I believe many people have doubts about what web front-end isomorphic rendering is. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what is web front-end isomorphic rendering?" Next, please follow the editor to study!

Homogeneous rendering means that both the front and back ends use js, and our HTML files are loaded with nodejs when rendering for the first time. In Xiaobai's words, homogeneous rendering is neither backend rendering nor front-end rendering, it is a common part between the two. The implementation of homogeneous rendering is actually SSR+CSH, and they are implemented through a piece of code.

Front-end rendering and back-end rendering are mentioned here, each of which has its own advantages. The advantages of front-end rendering include: local refresh, lazy loading technology, you can use js to achieve a variety of cool effects, you can access resources through the cdn server, front and rear separate development, relatively low learning cost. The main advantages of the back-end are: it can well solve the problem of loading the first screen, which is conducive to the optimization of seo.

With the development of technology, frameworks like Vue and React have been able to achieve good isomorphic rendering, which is often referred to as SSR, such as nuxt.js and next.js. In today's extremely common front-end rendering, why do we have the technology of homogeneous rendering?

As mentioned above, homogeneous rendering can actually solve the problems of slow loading of the first screen and optimization of SEO.

Traditional search engines grab the data we need from HTML files, so that the front-end rendered pages cannot be fetched. Developers who have developed vue and react projects know that SPA, which we often use, packages all JS as a whole. One problem that can not be ignored is that the file is too large, resulting in a long wait before rendering. Especially when the network speed is poor, it is not a good experience for users to wait for the white screen to end.

Server rendering can first render the used data to the final HTML for direct display, which can ideally avoid the problem of white screen. But nothing is absolute, if the amount of data on a page is too large, it is inevitable that there will be waiting for the situation to happen.

When it comes to the rendering mode of PHP,JSP, they are all HTML pages rendered by the template engine, which are given to the backend after the front end has finished writing the page, with the suffix php or jsp. In fact, the principle of SSR is the same, except that there is an extra layer of CSH, and its implementation requires the server to provide a piece of initialized data.

At this point, the study of "what is the isomorphic rendering of the web front end" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
