This time I will show you how to use @angular/cli V6.0 to develop PWA applications, and what are the precautions for using @angular/cli V6.0 to develop PWA applications. The following are practical cases. Let’s take a look.
What is PWA
PWA (Progressive Web App) utilizes TLS, webapp manifests and service workers to enable applications to install and use it offline. In other words, a PWA is like a native app on your phone, but it's built using web technologies like HTML5, JavaScript, and CSS3. When built correctly, PWAs are indistinguishable from native apps. The main features of PWA include the following three points:
- Reliable - even in unstable network environments, it can load and display instantly
- Stickiness - Like a native application on the device, with an immersive user experience where users can Add to desktop
- PWA itself emphasizes progressiveness and does not require all requirements for security, performance, and experience to be met at once. Developers can check existing features through the PWA Checklist.
Angular has officially released V6.0, and we can already use the corresponding @angular/cli V6.0 to directly develop PWA applications. Not much to say below, let’s take a look at the detailed introduction.
Step one: Install @angular/cli V6.0If you have an old version on your machine, please uninstall it first.
Open your terminal and execute:
npm install -g @angular/cli
After successful installation, use ng -v to check the version number:
Execution:
ng new test-ng-pwaAfter the creation is successful, take a look at the project and execute:
ng serve --openSeeing this interface in the browser means everything is OK:
Stop the project, and then execute it in the terminal:
ng add @angular/pwaThe effect is as follows: ##Because the built-in Server of @angular/cli is compiled with --prod Service-worker was not supported at that time, so a third-party lite-server was installed on it. Its official documentation is here:
https://npmjs.com/package/lite-server, please execute :
npm install lite-server --save-dev npm install lite-server --global
After installation, execute: npx ng build --prod && lite-server --baseDir dist/test-ng-pwa
Then open your browser to access port 3000. You can see that the service-worker has started successfully:
Android, and ChromeOS are all supported. Try it yourself!

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
