Any device with TCP/IP can interact with the application through HTTP requests. • We can interact with a REST API through a number of mediums: command line, Postman, or a web browser. • These applications create and send http requests to the REST API and receive http responses. • Postman can also be used for mocking APIs and automated testing. Javascript and DOM • As a simple example of consuming a REST API we will look at writing a low level single page application that interacts directly with the API. • It will use AJAX to send and receive requests from the server. • It will use Javascript and DOM to update the web page. • We will (redundantly) include it with an existing server-side rendering app. Single Page Applications • Single Page Applications have the browser/client do the heavy lifting in a web application: The server just provides the data while the client does the logic and rendering AJAX AJAX = Asynchronous JavaScript And XML. • AJAX is not a programming language. • AJAX just uses a combination of: – A browser built-in XMLHttpRequest object (to request data from a web server) – JavaScript and HTML DOM (to display or use the data) • AJAX is a misleading name. AJAX applications might use XML to transport data, but it is equally common to transport data as plain text or JSON text.

  • The Jasper Framework: Towards a Platform Independent, Formal Treatment of Web Programming
    The Jasper Framework: Towards a Platform Independent, Formal Treatment of Web Programming James Smith Imperial College London, United Kingdom [email protected] This paper introduces Jasper, a web programming framework which allows web applications to be developed in an essentially platform indepedent manner and which is also suited to a formal treat- ment. It outlines Jasper conceptually and shows how Jasper is implemented on several commonplace platforms. It also introduces the Jasper Music Store, a web application powered by Jasper and imple- mented on each of these platforms. And it briefly describes a formal treatment and outlines the tools and languages planned that will allow this treatment to be automated. 1 Introduction These days a web application may span both server and client side. Facebook is a good example, with much of the site’s functionality being implemented using JavaScript and executed in the browser. Com- munication between client and server sides is also, typically, not just characterised by requests from the browser, requests are also made by JavaScript in the form of Ajax calls. It is not at all obvious, for example, that Facebook fakes conventional browser requests. Clicking on menu items appears to result in such conventional requests being made, since the whole page seems to change, but in fact these are often Ajax calls and the whole page is changed dynamically, rather than a new page being served. In this way the chat pane can remain “on top”, while the page changes “underneath”. Such techniques used to characterise what were known as rich web applications but they are becoming so commonplace nowadays that a rich web application might be considered the norm.

    WaRR: A Tool for High-Fidelity Web Application Record and Replay Silviu Andrica and George Candea School of Computer and Communication Sciences École Polytechnique Fédérale de Lausanne (EPFL), Switzerland {silviu.andrica, george.candea}@epfl.ch Abstract—We introduce WaRR, a tool that records and interactions, and high-fidelity recording requires that all in- replays with high fidelity the interaction between users and teractions be recorded. Replaying fidelity quantifies correctly modern web applications. WaRR consists of two independent played back interactions, and high-fidelity replaying requires components: the WaRR Recorder and the WaRR Replayer. The WaRR Recorder is embedded in a web browser, thus that all interactions be realistically simulated. having access to user actions, and provides a complete inter- High-fidelity record and replay is challenging because the action trace—this confers high recording fidelity.

    SCHOOL OF COMPUTING DEPARTMENT OF COMPUTER SCIENCE AND ENGINEERING UNIT – I-Rich Internet Applications – SCS1401 I. Rich Internet Application Overview Introduction to Web2.0 - Key characteristics of Rich Internet Application - Current Rich Internet Application platforms - Rich Internet Application benefits - Rich Internet Application patterns and best practices - Rich Internet Application architecture - Restful Web Services with Nodes. Introduction to Web 2.0 Web 1.0 • Web 1.0 refers to the first stage in the World Wide Web • Entirely made up of web pages connected by hyperlinks. • A set of static websites that were not yet providing interactive content. • Used as “Information portal”. Examples: Amazon,Yahoo, Personal web pages Web 2.0 • Web 2.0 is the term used to describe a variety of web sites and applications that allow anyone to create and share online information or material they have created. • It allows people to create, share, collaborate & communicate. • Allows everyone to produce their content. • Gives the users the possibility to control their data. • Web 2.0 allows groups of people to work on a document or spreadsheet simultaneously. • In the background a computer keeps track of who made what changes where and when. • Web-based applications can be accessed from anywhere. • Web 2.0 Examples • Web applications ( Google Docs, Flickr) • Video sharing sites (YouTube) • Wikis (Media Wiki) • Blogs (WordPress) • Social networking (Facebook) • Microblogging (Twitter) • Hosted services (Google Maps) Web 3.0 • It refers to the evolution of web utilization and interaction which includes altering the Web into a database. • It enables the upgradation of back-end of the web, after a long time of focus on the front- end • Data isn’t owned but instead shared, where services show different views for the same web / the same data.

MATTHIEU PIZENBERG le vendredi 28 février 2020 Titre : Interactive Computer Vision through the Web Ecole doctorale : Mathématiques, Informatique, Télécommunications de Toulouse (MITT) Unité de recherche : Institut de Recherche en Informatique de Toulouse ( IRIT) Directeur(s) de Thèse : M. VINCENT CHARVILLAT M. AXEL CARLIER Rapporteurs : M. MATHIAS LUX, ALPEN ADRIA UNIVERSITAT Mme VERONIQUE EGLIN, INSA LYON Membre(s) du jury : Mme GÉRALDINE MORIN, TOULOUSE INP, Président M. AXEL CARLIER, TOULOUSE INP, Membre M. CHRISTOPHE DEHAIS, ENTREPRISE FITTINGBOX, Membre M. OGE MARQUES, FLORIDA ATLANTIC UNIVERSITY, Membre M. VINCENT CHARVILLAT, TOULOUSE INP, Membre ii Acknowledgments First I’d like to thank my advisors Vincent and Axel without whom that PhD would not have been possible. I would also like to thank Véronique and Mathias for reviewing this manuscript, as well as the other members of the jury, Oge, Géraldine and Christophe for your attention, remarks and interesting discussions during the defense. Again, a special thank you Axel for all that you’ve done, throughout this long period and even before it started. I haven’t been on the easiest path toward completion of this PhD but you’ve always been there to help me continue being motivated and that’s what mattered most! Wanting to begin a PhD certainly isn’t a one-time moment, but for me, the feeling probably started during my M1 internship. I was working in the VORTEX research team (now REVA) on a project with Yvain and Jean-Denis and it was great! Yet “I don’t think so” was more or less what I kept answering to my teachers when they would ask if I wished to start a PhD at that time.
