Mitigating Javascript's Overhead with Webassembly
Samuli Ylenius Mitigating JavaScript’s overhead with WebAssembly Faculty of Information Technology and Communication Sciences M. Sc. thesis March 2020 ABSTRACT Samuli Ylenius: Mitigating JavaScript’s overhead with WebAssembly M. Sc. thesis Tampere University Master’s Degree Programme in Software Development March 2020 The web and web development have evolved considerably during its short history. As a result, complex applications aren’t limited to desktop applications anymore, but many of them have found themselves in the web. While JavaScript can meet the requirements of most web applications, its performance has been deemed to be inconsistent in applications that require top performance. There have been multiple attempts to bring native speed to the web, and the most recent promising one has been the open standard, WebAssembly. In this thesis, the target was to examine WebAssembly, its design, features, background, relationship with JavaScript, and evaluate the current status of Web- Assembly, and its future. Furthermore, to evaluate the overhead differences between JavaScript and WebAssembly, a Game of Life sample application was implemented in three splits, fully in JavaScript, mix of JavaScript and WebAssembly, and fully in WebAssembly. This allowed to not only compare the performance differences between JavaScript and WebAssembly but also evaluate the performance differences between different implementation splits. Based on the results, WebAssembly came ahead of JavaScript especially in terms of pure execution times, although, similar benefits were gained from asm.js, a predecessor to WebAssembly. However, WebAssembly outperformed asm.js in size and load times. In addition, there was minimal additional benefit from doing a WebAssembly-only implementation, as just porting bottleneck functions from JavaScript to WebAssembly had similar performance benefits. -

A Closer Look at Webassembly
A closer look at WebAssembly Denis Eleskovic 26th August, 2020 Faculty of Computing Blekinge Institute of Technology SE-371 79 Karlskrona Sweden This diploma thesis is submitted to the Faculty of Computing at Blekinge Institute of Technology in partial fulfillment of the requirements for the diploma degree in Software Engineering. The thesis is equivalent to 10 weeks of full time studies. Contact Information: Author: Denis Eleskovic E-mail: [email protected] University advisor: Andreas Arnesson Department of Software Engineering Faculty of Computing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE-371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 ii (45) ABSTRACT WebAssembly is a new emerging technology for the web which offers a low-level bytecode format for other languages to compile to. The aim of the technology is to effectively speed up the performance of the web, as well as to offer a way for developers to port existing libraries and code that were written in static languages such as C/C++ or Rust. The technology is currently supported in all the major browsers of today. This study takes a closer look at how the technology works and how it is compiled and executed across two of the major browsers as compared to JavaScript. Furthermore, a smaller experiment was conducted where AssemblyScript was used to compile to WebAssembly, with AssemblyScript being a typescript-to-WebAssembly compiler. The two technologies were then tested in terms of runtime performance and consistency across two browsers, operating systems as well as with different optimizations. -
A Standalone Webassembly Development Environment for the Internet of Things
A Standalone WebAssembly Development Environment for the Internet of Things Istv´anKoren[0000−0003−1350−6732] Chair of Process and Data Science, RWTH Aachen University, Aachen, Germany [email protected] Abstract. In Industry 4.0, there is a growing demand to perform high- performance and latency-sensitive computations at the edge. Increas- ingly, machine data is not only collected but also processed and trans- lated into actionable decisions influencing production parameters in real- time. However, heterogeneous hardware in the Internet of Things pre- vents the adoption of consistent development and deployment structures as known from service containers. WebAssembly is a recent hardware- agnostic bytecode format that is capable of running not only in the browser, but also on microcontrollers and in cloud environments. In this article, we argue that this web technology can have a real impact by lever- aging tools and programming languages that web engineers are familiar with. As a first step, we present a proof-of-concept integrated develop- ment and deployment environment to execute WebAssembly modules on microcontrollers. Its key feature is a built-in web server that provides a self-contained browser-based IDE to directly develop, compile and flash AssemblyScript code to a device. In this sense, the Web of Things will unfold a streamlined development and deployment context for the ag- ile and low-latency operationalization of adjustable data streaming and action-oriented process adaptations for industrial devices. Keywords: WebAssembly · Internet of Things · Industry 4.0. 1 Introduction Digitalization of industrial assets comes with many promises like higher pro- ductivity, less rejects and smaller lot sizes. -
My First Production Isomorphic React Graphql Project 31 May 2016
Fraser Xu My First Production Isomorphic React Graphql Project 31 May 2016 The story During the past few weeks, I’ve been given the opportunity to rebuild the front-end of a project with “modern approach” to replace an existing CoffeeScript, jQuery, Bower based app running on Ruby on Rails. After about 2 sprints of work(2 weeks for each sprint), we shipped our first version to production last week. Before I started to share my experience, I’d like to give an overview of the architecture for the project. The current stack Library View React State send-actions(like Redux, but management simper) Date fetching GraphQL, Relay Route React-Router Assets serving Webpack Precompile JS Babel Node.js(for server side Server rendering React) Why the current stack? I’ve worked on lots of different projects before with different stacks. And I always have the idea to not use any boilerplate in mind when start a new project. Boilerplates are usually built by and for people with different requirements for a project, and none of them are identical to the one you are trying to build. So usually I will only keep a list of well maintained boilerplate project, and only use them as a reference when my own stack gets into trouble. The new project has a few requirements: Server side rendering for progressive enhanced experience so the page could work for user without JavaScript SEO, we are mainly an e-commercial website, so SEO is the number one priority The app needs to talk to a couple of micro- services, and tokens are usually stored on the server for safety reasons UI state should persist from url, not only for SEO, but also for a better user experience Fast iteration time, to move fast and delivery better user experience Improve performance, the short time we delivery page to user, the longer we can keep the user on the website There are also other requirements which are not for business, and most of them are actually for a better developer experience.
