It broadly outlines and discusses the practice of front-end engineering: how to learn it and what tools are used when practicing it in It is specifically written with the intention of being a professional resource for potential and currently practicing front-end developers to equip themselves with learning materials and development tools. Secondarily, it can be used by managers, CTOs, instructors, and head hunters to gain insights into the practice of front-end development.
The materials referenced and discussed in the book are either best in class or the current offering to a problem. The book should not be considered a comprehensive outline of all resources available to a front-end developer. The value of the book is tied up in a terse, focused, and timely curation of just enough categorical information so as not to overwhelm anyone on any one particular subject matter. The intention is to release an update to the content yearly. This is currently the fourth year an edition has been released. Chapter 0 provides a lite recap of the year in front-end development and what may be to come.
Chapter 5 organizes and list the tools used by front-end developers and Chapter 6 highlights front-end information outlets. This chapter provides a baseline explanation for front-end development and the front-end developer discipline.
Diagnostic tests like these send the system a request to perform an action, and that request generates signals, such as other CAN packets, that are used to perform the work. Choose the textbook packaged with the resources that best meet your course and student needs. Not to be confused with Google Goggles. I think I just found a very nice femur there. Tag values also have an attrs attribute that shows all the HTML attributes of the tag as a dictionary. The arguments passed to these functions typically include the start address of a table, its structure or shape, and which variables index elements of the table.
This is further complicated by the fact that users now use a large variety of devices with varying screen sizes and resolutions thus forcing the designer to take into consideration these aspects when designing the site. They need to ensure that their site comes up correctly in different browsers cross-browser , different operating systems cross-platform and different devices cross-device , which requires careful planning on the side of the developer.
These four run times scenarios are explained below. A web browser is software used to retrieve, present, and traverse information on the WWW.
Typically, browsers run on a desktop or laptop computer, tablet, or phone, but as of late a browser can be found on just about anything i. The most common web browsers are shown in order of most used first :. Headless browsers are a web browser without a graphical user interface that can be controlled from a command line interface programmatically for the purpose of web page automation e. Think of headless browsers as a browser that you can run programmatically from the command line that can retrieve and traverse web page code. Webviews are used by a native OS, in a native application, to run web pages.
Think of a webview like an iframe or a single tab from a web browser that is embedded in a native application running on a device e.
The most common solutions for webview development are:. Eventually, what is learned from web browser development can be used by front-end developers to craft code for environments that are not fueled by a browser engine i. As of late, development environments are being dreamed up that use web technologies e. This chapter will break down and broadly describes the practice of front-end engineering starting with, "How Front-End Developers Are Made".
If you were to set out today to become a front-end developer I would loosely strive to follow the process outlined below Chapter 3 and Chapter 4 will dive into more details on learning resources. A short word of advice on learning.
However, if you need someone to tell you how to take and learn what is low cost to free, and hold you accountable for learning it, you should consider a traditional instructor lead class room setting. Otherwise, I am not aware of any other profession that is practically free for the taking with an internet connection, a couple of dollars a month for screencasting memberships , and a burning desire for knowledge. For example, if you want to get going today, consuming one or more of the following self-directed resources below can work:. When getting your start, you should fear most things that conceal complexity.
Abstractions e. It is assumed that on this journey you are not only learning, but also doing as you learn and investigate tools. Some suggest only doing to learn. While others suggest only learning about doing. I suggest you find a mix of both that matches how your brain works and do that.
But, for sure, it is a mix! So, don't just read about it, do it. Learn, do.
Repeat indefinitely because things change fast. This is why learning the fundamentals, and not abstractions, are so important. A great divide has been brewing in the front-end developer space for several years between two very different types of so-called front-end developers.
This role typically requires computer science knowledge and years of software development experience.

Front-End Accessibility Expert : When the word "Accessibility" is included in the job title, this will denote that the developer has extensive experience crafting front-end technologies that support accessibility requirements and standards. Front-End Dev. Ops : When the word "DevOps" is included in the job title, this will denote that the developer has extensive experience with software development practices pertaining to collaboration, integration, deployment, automation, and quality.
The following core web technologies are employed by front-end developers consider learning them in this order :. For a comprehensive list of all web related specifications have a look at platform. The nine technologies just mentioned are defined below along with a link to the relevant documentation and specification for each technology. Web browsers can read HTML files and render them into visible or audible web pages. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.
Cascading Style Sheets CSS is a style sheet language used for describing the look and formatting of a document written in a markup language.
Below is a list of all the interfaces that is, types of objects that you may be able to use while developing your Web app or site. Code for parsing and generating JSON data is readily available in many programming languages. The ECMA standard is minimal, describing only the allowed grammar syntax, whereas the RFC also provides some semantic and security considerations. The JSON filename extension is. Accessibility refers to the design of products, devices, services, or environments for people with disabilities. Beyond the skills just mentioned, a front-end developer might also be specifically skilled in one or more of the following:.
Generally speaking, front-end technologies can run on the aforementioned operating systems and devices using the following run time web platform scenarios:.
