We know the programming structures that are used as a basis for software development so that developers avoid having to start writing from scratch each time they program new software, which would result in a great inefficiency. There are proven proposals in the form of program codes for a large number of standard functions in the field of software development. Generally, within the framework of the object-oriented programming, classes come into play that is used as software object execution projects. In general, a framework represents a collection of different classes that cooperate with each other and that determines, thus, the basic structure of each software that will be developed by taking this framework as a basis. Frameworks for web applications, whose abbreviated form is a web framework.
As a basis for software development, web frameworks should offer simple and clear structures that facilitate their maintenance and make it possible for developers to create web applications in a short period of time. To comply with these requirements, many web frameworks refer to three basic principles of design:
Do not repeat yourself (DRY): the principle of not repeating has to do with avoiding redundancy. Redundant information, such as duplicate codes, which can be avoided, has a negative effect on software maintenance, since, in the case of having to adapt the code fragments, changes must be made in different parts of the software. Program code.
Keep it short and simple (KISS): to a problem, a solution. This is the basic principle of the KISS paradigm, which is oriented to the principle of parsimony or economy: if more than one solution is found for a given situation, one should choose the one that requires the least number of hypotheses and variables. To use a framework or to solve a specific problem should use the least amount of code possible.
Convention over configuration: the greater the configuration, the greater the effort necessary for its management. On the contrary, conventions offer the possibility of reducing complexity. Therefore, web frameworks should establish accredited procedures in the form of a default configuration and offer, optionally, other configuration possibilities.
If these design principles are taken into account, the application of web frameworks in software development offers numerous advantages. However, the advantages of frameworks also entail certain limits for developers, who consider some structural restrictions as disadvantages.
Advantages of web frameworks
The use of web frameworks in the field of software development is motivated by a reduction in both time and costs. The fundamental idea is, in this respect, the reuse of the codes. This is, above all, related to basic functions such as database connections, templates for creating web pages, caching or security-related functions, which frameworks make available in the form of code modules. With this, the efforts derived from software development are limited to the specific program code of the new application. Due to the fact that most web frameworks are proposed as free and free software, they generally do not generate acquisition costs.
In addition, frameworks encourage the generation of cleaner source codes, since for standard functions developers can resort to already tested components. The fragments of code available in the frameworks experience, for the most part, numerous development cycles and are continuously optimized thanks to a community that acts as a tester and collaborates in the development tasks, which allows to discover and eliminate security breaches. of new components quickly in the case of large-scale projects. In the forums of the projects, partly moderated by support teams, an exchange between users and developers also takes place.
Disadvantages of web frameworks
On the Internet, there is an overwhelming number of frameworks for website development services in London that differ from each other both in the principle of structuring and the spectrum of functions, so that software projects may even require the application of different web frameworks. In this sense, developers are faced with the problem of having to choose the most appropriate structure for their project. Frequently, arrangements are made to adopt the boundaries of the framework to the project in question. Because frameworks are conceived as universal solutions, developers rarely use all the functions of the fixed structure. Depending on the volume of the framework, applications may contain more code than necessary, so in this case, you can talk about over a load of code.
Another disadvantage is the fact that developers tend to depend on a particular manufacturer or a community of developers and, in special cases, the use of frameworks is linked to certain license conditions. In addition, problems may arise when the development of frameworks is suspended. Because the developers have to become familiar with the creation of the corresponding program structure and with the possibilities of use, a certain period of adaptation is needed, although this is relativized by the time saving that comes with the predefined functions and code components. In this sense, critics refer to the risk of losing basic knowledge, since users who program based on the fundamentals of frameworks no longer deal so much with the programming languages used.
Because you can freely access the source code of most web frameworks, in principle everyone can become familiar with it. Applications for business use that are developed on the basis of public access code components tend to be, in the eyes of hackers, more transparent than the apps themselves, which do not have an open source.
