pass, otherwise the project release will not be allowed.Permission SystemFor security issues in scenario 3, we need to establish a permission system. Developers only retain the permissions of the requested deployment, the server to which the project is deployed, the specific path, and the deployed environment are transparent to the developer, so the developer only needs to focus on the business. The proces

word to describe is: frequent. 　　 Plus now the popularity of hybrid apps, Web page update speed, but also for the front-end code frequently updated to provide "objective conditions." 　　 Human nature is more entangled in what is now visible, so front-end developers bear the pressure from the customer, from the product

At present, the Web product interaction is more and more complex, user experience and site front-end performance optimization These all rely on the Web front-end engineers to do, web front-end engineers are design and development

understand my experience, web front-end engineers in web development, to give the page a better sense and structure, richer labels with RDFA micro-data and micro-format and other ways to support the construction of programs, users are more valuable data-driven web. The biggest advantage of HTML5 mobile phone application is that it can be debugged and modified directly on the Web page, the native applicatio

process, the design team usually needs to first design the mockup or demo (html/CSS) interface, and then the developer starts to formally write the code. However, in most cases, developers and designers need to intervene in the early stage of the project to ensure the project progress. The difference is that most developers review the Project Plan (PRD) and prototype review, they are more concerned with technical implementation. Designers prefer to u

career in this proposal: the first choice of new industries, the second choice of new enterprises, the third choice of new departments. The internet industry is a new industry compared to traditional industries; there are many startups; Web front-end engineers are a new post. China's Web front-end engineers are starti

, but you want to be a good front-end development engineer, you should be the maintainer (developer) of these excellent libraries, not just use them. Simply using those good libraries doesn't make you understand the core of the problem. Only try to write some of your own library, and constantly maintain, optimize the code so that you can learn more, why not try i

that the different role of the product understanding and focus is very different. According to the normal project process, the design team usually needs to design the interface mockup or demo (HTML/CSS) before the developer begins to write the code formally. However, in most cases, developers and designers need to be involved in the project upfront in order to ensure the project's progress, and most of the developers are audited through the project

component are maintained near this directory; Because components are independent, components and components can be free combination; A page is simply a container of components, responsible for composing components to form a fully functional interface; You can delete/replace the entire directory when you do not need a component, or if you want to replace the component. The second description of the nearest maintenance principle, I think the most engineering value of the place, it provides a good

Therefore, as a front-end developer, you must master the features of the following mainstream browsers: Mozilla Firefox Chrome Microsoft Internet Explorer Opera Apple Safari While Mastering these browser features, you also

sacrifice, through the ads, we have pre-processing language normalization, the project directory normalization, and even the use of pre-processing methods are standardized (not tender use advanced features). The developer does not care about the environment and does not need to be configured. After five or six years of development experience, many of the problems encountered in development have given me profound influence, knowing that

Problem One: Reactjs components are difficult to reuse in complex interactive pagesThe smallest unit of reuse in a Reactjs is a component. Reactjs components are lighter than ANGULARJS controllers and view. Each component requires only the front-end developer to provide a render function that props maps and map to a state Web page element.Such lightweight compone
