- 6. Definition of Website A website (also written as web site) A collection of web pages and related content Identified by a common domain name Published on at least one web server. wikipedia.org, google.com, amazon.com, and etc…
- 7. Introduction to Web • A document on the web is called a Web Page. • A Web page is identified by Uniform Resource Locator (URL). • A URL is also commonly referred to as a Web Address. • A website refers to the location on the internet of the Web pages and related files.
- 8. What is Web Development?
- 9. Definition: Developing a Web site for the Internet or an intranet. Range from developing A simple single static page of plain text to complex web applications, electronic businesses, and social network services.
- 12. Front-end
- 13. Three Layers of Web Design
- 14. HTML
- 15. Do you imagine how this page would like without HTML
- 16. Looks ugly… Doesn’t it ?
- 17. No HTML •Without any markup to give your page content structure, the browser renders unformatted and unstyled text. •HTML Tags give structure and meaning to your content.
- 18. Let us Add HTML tags to our page… Looks Better…. But still not Good …
- 19. But What should we do to make the page look nice ? The answer is use CSS….
- 20. CSS = Cascading Style Sheet
- 21. Rules: Set of rules defining how an html element will be “presented” in the browser. CSS Rules: p { color: red; } #title { font-style: italic; Border: 1px dotted blue; } .content { Font-weight: bold; Background: yellow; } 21
- 22. Something can and can’t change with CSS: Can Change • colors • font • font size • backgrounds • spacing • sizes • borders • Position(layout) Can’t change • content • Markup
- 23. After adding CSS to page: Looks Perfect !
- 24. Text + HTML + CSS = Web Page
- 25. Now time for Actions ! Java Script
- 26. JavaScript is not a Java: • JavaScript was not developed at Sun Microsystems, the home of java. • JavaScript was developed at Netscape in 1995. • It’s not a light version of Java. • It was not based on Java.
- 27. JavaScript: Classic JavaScript is a client-side language used to add interactivity to your web pages.
- 28. What can do with JavaScript?
- 29. What can do with JavaScript?
- 30. Some JavaScript Frameworks in Recent Trend: • Angular JS • React JS • Node JS • Vue JS
- 32. Python: Now, it's my belief that Python is a lot easier than to teach to students programming and teach them C or C++ or Java at the same time because all the details of the languages are so much harder. Other scripting languages really don't work very well there either. - Guido van Rossum.
- 33. Python • Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding. • One area where Python shines is web development. Python offers many frameworks to power some of the world’s most popular sites such as Spotify, Mozilla, Reddit, the Washington Post and Yelp.
- 34. Python Frameworks: • A framework is a collection of modules or packages which helps in writing web applications. While working on frameworks in python we don’t have to worry about the low level details such as protocols, sockets or thread management.
- 35. Operations Involved in Frameworks: • Url Routing – Routing is the mechanism of mapping the URL directly to the code that creates the web page. • Input form handling and validation – Suppose you have a form which takes some input, the idea is to validate the data and then save it. • Output formats with template engine – A template engine allows the developers to generate desired content types like HTML, XML, JSON.
- 36. Operations Involved in Frameworks: • Database connection – Database connection configuration and persistent data manipulation through an ORM. • Web security – Frameworks give web security against cross-site request forgery aka CSRF, sql injection, cross-site scripting and other common malicious attacks. • Session storage and retrieval – Data stored in the session storage gets cleared when the page session ends.
- 37. Classification of Frameworks: • Full (high-level) - Come with many pre installed components and lot of low level task automation. • Micro (low-level) - Come with many pre installed components and lot of low level task automation.
- 38. Python Frameworks: • Full (high-level) • Django • Web2py • Turbogears • Micro (low-level) • Flask • Pyramid • CherryPy • Bottle.py
- 39. MySQL: • MySQL is the most popular database system used in Web Development. • MySQL is a database system used on the web. • MySQL is a database system that runs on a server. • MySQL is ideal for both small and large applications. • MySQL is very fast, reliable, and easy to use. • The data in a MySQL database are stored in tables. A table is a collection of related data, and it consists of columns and rows.
- 41. Job Options in Web Development: • Application Developer. • Web developer. • UI/UX Developer. • Web Content Manager.
