Creating custom APIs to solve shortcomings in existing JavaScript Front-End Frameworks

Sammanfattning: The technology of creating web-based applications has been expanding and making better user interfaces that can support many different focus groups, such as building a website that is flexible and easy-to-use for children and/or the elderly. Another expansion has been in the field of storages of data and connectivity. These technologies, however, have a steep learning curve for new developers. With the rise of these new techniques, a unique contemporary set of skills have been introduced, the Front-End, which is a layer that involves the presentation aspect of an application. React.js is a popular JavaScript framework for front-end development. It has become the most framework for user  interface design. In today’s market there are several other frameworks that one can utilize for front-end solutions such as Angular v2 and Vue.js. The results of this thesis is the improvement on creating a developer friendly custom creation of unique elements. By following proper processes when using the API, one can learn and create their own custom API to their own liking. The API created is a basic GUI addition to React, which enables a Log-In interface that can be easily manipulated by following the thesis, and/or by tracing the steps in the code. This is useful for those that want to have a template GUI API.
