Introduction to front-end engineering system construction

Brief description

I had the honor to attend the TFC Tencent Web Front-end Conference last week and witnessed the wonderful speeches of various front-end masters, which were full of useful information. The conference process is divided into a main venue in the morning and three sub-venues in the afternoon. The topics shared cover front-end cutting-edge content such as new Web technologies, Node.js, frameworks, engineering, and graphics processing. It also includes valuable experiences with Tencent’s front-end characteristics such as extreme performance optimization and massive user operations, which have good practical reference value. . The front-end has developed rapidly in recent years, evolving from simple pages to increasingly complex web applications. In order to cope with this huge business development, a variety of tools have been produced to improve development efficiency, such as the innovation of front-end frameworks. And the front-end is moving toward engineering, driving technology development through business, and using technology to improve business. The front-end is no longer the same, and has slowly entered the stage of history, haha.
Because there are too many topics shared, I cannot attend the lectures one by one. I mainly listened to several topics of interest in the main venue: front-end engineering system construction, V8 performance optimization for front-end developers, and TC39 by foreign lecturer Nicolas. , ECMAScript sharing.

Front-end engineering system construction

This topic was shared by Zhang Yunlong, a master of front-end engineering in the industry, the core developer of FIS construction tools, and the current CTO of National Broadcasting. The main purpose of front-end engineering is to implement a set of standard process specifications through engineering and improve front-end development efficiency. A series of practices such as performance optimization, build tools, continuous integration, test deployment, release monitoring, and agile development have greatly improved productivity. I chose this topic mainly because the construction tool used in project development is FIS. Through sharing, I can gain a deeper understanding of the construction principles. Currently, construction tools are used to achieve code compression, merging, local debugging, etc., which facilitates daily development work. The master talked about the problems and solutions encountered in front-end engineering practice from his own business environment, which has very good practical value. The key points are as follows:

• Front-end architecture: component development + subsystem split

• Continuous integration: based on Gitlab-CI environment and GitFlow development specifications

• System testing: Automatic regression checking system based on Dom-Diff.

• Agile Development: Physical Kanban (Recommended Reading "Kanban Practice")

V8 Performance Optimization

MIDU (justjavac ) The content shared by the master this time is slightly advanced and involves the working principle of the javascript engine. By learning the relevant knowledge of JavaScript engine optimization, you can write JavaScript code with better performance.
