Unlike traditional applications, progressive web apps are a hybrid of regular web pages or websites and a mobile application. This new application model attempts to combine features offered by most modern browsers with the benefits of mobile experience. In , designer Frances Berriman and Google Chrome engineer Alex Russell coined the term "Progressive Web Apps" to describe apps taking advantage of new features supported by modern browsers, including Service Workers and Web App Manifests, that let users upgrade web apps to be first-class applications in their native OS.
Web development tools allow web developers to test and debug their code. They are different from website builders and IDEs in that they do not assist in the direct creation of a webpage, rather they are tools used for testing the user facing interface of a website or web application. Web development tools come as browser add-ons or built in features in web browsers. The most popular web browsers today like, Google Chrome, Firefox, Opera, Internet Explorer, and Safari have built in tools to help web developers, and many additional add-ons can be found in their respective plugin download centers.
Due to the increasing demand from web browsers to do more popular web browsers have included more features geared for developers. While most browsers come equipped with web developer tools, the Chrome developer tools are currently the most talked about and widely used. I'd suggest learning and using the Chrome web developer tools , simply because the best resources for learning web developer tools revolves around Chrome DevTools.
A command-line interface or command language interpreter CLI , also known as command-line user interface, console user interface, and character user interface CUI , is a means of interacting with a computer program where the user or client issues commands to the program in the form of successive lines of text command lines.

It typically maintains a database of software dependencies and version information to prevent software mismatches and missing prerequisites. A component of software configuration management, version control, also known as revision control or source control, is the management of changes to documents, computer programs, large web sites, and other collections of information.
Changes are usually identified by a number or letter code, termed the "revision number," "revision level," or simply "revision. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and with some types of files, merged. The most common solution used for version control today is Git. Learn it! Build automation is the process of automating the creation of a software build and the associated processes including: compiling computer source code into binary code, packaging binary code, and running automated tests.
Gulp is great. However, you might only need npm run. Before turning to additional complexity in your application stack ask yourself if npm run can do the job. If you need more, use Gulp. Web performance optimization, WPO, or website optimization is the field of knowledge about increasing the speed in which web pages are downloaded and displayed on the user's web browser. With the average internet speed increasing globally, it is fitting for website administrators and webmasters to consider the time it takes for websites to render for the visitor. Unit Testing - In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.
Intuitively, one can view a unit as the smallest testable part of an application. Functional Testing - Functional testing is a quality assurance QA process and a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered not like in white-box testing.
Functional testing usually describes what the system does. It occurs after unit testing and before validation testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing. Headless browsers provide automated control of a web page in an environment similar to popular web browsers, but are executed via a command line interface or using network communication.
PhantomJS is no longer maintained , Headless Chrome steps in. Offline development aka offline first is an area of knowledge and discussion around development practices for devices that are not always connected to the Internet or a power source. A website or web application can run on a wide range of computers, laptops, tablets and phones, as well as a handful of new devices watches, thermostats, fridges, etc. How you determine what devices you'll support and how you will develop to support those devices is called, "multi-device development strategy".
Below, I list the most common multi-device development strategies. This chapter highlights a few options for instructor directed learning via front-end development schools, courses, programs, and bootcamps. The table below contains a small selection of instructor-led courses i.
Use the table to get a general idea of what is available, the cost, duration, and locations of courses. Be aware the information can change quickly. If you can't afford a directed education can be very expensive , a self directed education using screencasts, books, and articles is a viable alternative to learn front-end development for the self-driven individual. This chapter identifies the tools of the trade. Make sure you understanding the category that a set of tools falls within, before studying the tools themselves.
Note that just because a tool is listed, or a category of tools is documented, this does not equate to an assertion on my part that a front-end developer should learn it and use it. Choose your own toolbox. I'm just providing the common toolbox options. A source code editor is a text editor program designed specifically for editing source code of computer programs by programmers.
It may be a standalone application or it may be built into an integrated development environment IDE or web browser. Source code editors are the most fundamental programming tool, as the fundamental job of programmers is to write and edit source code. Front-end code can minimally be edited with a simple text editing application like Notepad or TextEdit.
But, most front-end practitioners use a code editor specifically design for editing a programming language. Code editors come in all sorts of types and size, so to speak. Selecting one is a rather subjective engagement. However, I do strongly believe, minimally, a code editor should have the following qualities by default or by way of plugins :. Used to share limited amounts of immediately runnable code.
Not a true code editor but a tool that can be used to share small amounts of immediately runnable code in a web browser. I recommending using Visual Studio Code because of the quality of the tool and the continuous improvements made to the editor that likely won't stop or slow due to the fact that Microsoft is behind the tool.
It is widely used:. Share target browsers between different front-end tools, like Autoprefixer, Stylelint and babel-preset-env. No browser engine or WebView is used. The UI is constructed from native UI components. Then I'd work my way to React. If you are building a simple website that has minimal interactions with data i.zq-dev.quadmetrics.com/10926.php

A lot of work can be done with a task runner like Gulp and jQuery , while avoiding the unnecessary complexity of learning and using an app framework tool. Want something smaller than React, consider Preact. Preact is an attempt to recreate the core value proposition of React or similar libraries like Mithril using as little code as possible, with first-class support for ES If you are building something that needs a grid, spreadsheet, or pivot grid you'll have to look at Kendo UI or Webix. Keep in mind that most of these solutions still require jQuery. For more tools look here.
Before reaching for Gulp make sure npm scripts or yarn script won't fit the bill.
