Download: PDF epub. This is a guide that everyone can use to learn about the practice of front-end development. 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.

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.

Front-end web development, also known as client-side development is the practice of producing HTML, CSS and JavaScript for a website or Web Application so that a user can see and interact with them directly. The challenge associated with front end development is that the tools and techniques used to create the front end of a website change constantly and so the developer needs to constantly be aware of how the field is developing. The objective of designing a site is to ensure that when the users open up the site they see the information in a format that is easy to read and relevant.

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.

A front-end developer architects and develops websites and web applications using web technologies i. A person enters into the field of front-end development by learning to build a website or web application which relies on HTML, CSS, and JavaScript and commonly runs in a web browser but can also run in a headless browser , WebView , or as compilation input for a native runtime environment.

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".

How exactly does one become a front-end developer? Well, it's complicated. Just consider this road map:. Today, in general, one can't go to college and expect to graduate with a degree in front-end engineering. And, I rarely hear of or meet front-end developers who suffered through what is likely a deprecated computer science degree or graphic design degree to end up writing HTML, CSS, and JavaScript professionally. From my perspective, most of the people working on the front-end today generally seem to be self-taught from the ground up or cross over into the front-end space from design or computer science fields.

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.

go here Learn the actual underlying technologies, before learning abstractions. Don't learn jQuery, learn the DOM. Don't learn TypeScript, learn JavaScript. Don't just use Bootstrap, learn UI patterns. These avenues of becoming a front-end developer are typically teacher directed courses, that follow a more traditional style of learning, from an official instructor i. Keep in mind, if you are considering an expensive training program, this is the web! Everything you need to learn is on the web for the taking, costing little to nothing.

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.

On the one side, you have JavaScript-focused programmers who write JavaScript for front-end runtimes that likely have computer science skills with a software development history. In , when entering or trying to understand the front-end developer space you will absolutely feel this divide. The term front-end developer is on the verge of meaninglessness without clarifying words to address what type of front-end developer is being discussed. Below is a list and description of various front-end job titles Keep in mind titles are hard. The common, or most used i. Front-End Engineer aka JavaScript Developer or Full-stack JavaScript Developer : The job title given to a developer who comes from a computer science, engineering, background and is using these skills to work with front-end technologies.

This role typically requires computer science knowledge and years of software development experience.

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.

Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications. A uniform resource locator URL also called a web address is a reference to a resource that specifies the location of the resource on a computer network and a mechanism for retrieving it. URLs occur most commonly to reference web pages http , but are also used for file transfer ftp , email mailto , database access JDBC , and many other applications.

The nodes of every document are organized in a tree structure, called the DOM tree. Objects in the DOM tree may be addressed and manipulated by using methods on the objects. JavaScript is a high level, dynamic, untyped, and interpreted programming language. Alongside HTML and CSS, it is one of the three essential technologies of World Wide Web content production; the majority of websites employ it and it is supported by all modern web browsers without plug-ins. JavaScript is prototype-based with first-class functions, making it a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.

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:.
