Gutenberg: You Can't Teach an Old Dev New Tricks - WordCamp Chicago 2018Mike Hale
Gutenberg is coming, and it’s bringing a lot of changes to how WordPress themes and plugins will be developed. What does that mean for a a grumpy, old developer like me? Well if you want to keep working in WordPress, it means it’s time to buckle down and lean something new. In this session we’ll cover some of the changes Gutenberg means for developers, and all the new tools, languages and libraries you need to to learn to start to develop with Gutenberg.
Are you having trouble with all the things happening in web technology lately? Frustrated with the rate of change? Hard to keep up? Then we have good news for you: a little while ago, we at Jayway did a tech radar on web technology and we would like to share it with you.
Some of the technologies we will cover are: ECMAScript 6, React, Angular, Ember, Isomorphic/Universal web applications, Unidirectional client data flow, Backend-as-a-Service, Meteor, and Static site generators.
We will also do a small comparison of the web tech radar we did 18 months ago, and draw conclusions from the differences and the current rate of change.
Finally, we'll give some advices for navigating in the ever changing landscape of new web technology.
The document discusses hosting and scaling ASP.NET Core Blazor Server applications using SignalR and the Azure SignalR Service. It covers how SignalR enables real-time functionality using techniques like WebSockets, Server-Sent Events and long polling. It also discusses scaling options for SignalR like using sticky sessions, TCP connections and a Redis backplane. The Azure SignalR Service is presented as a scalable option with pricing information. A demo and bonus content on CircuitHandler are also mentioned.
Website cloning refers to copying an existing website's design or scripts to create a new website without having to write new code. There are two main types of website cloning: script cloning and design cloning. Script cloning involves copying the backend scripts that control a website's functionality, while design cloning copies the frontend layout and design but allows changing the content. The document then explains how to clone a website using the backtrack 5 operating system by copying its scripts and design.
- Server-side rendering techniques like pjax and client-side includes allow for partial page updates and better caching while enabling cross-team components and server-driven updates.
- These techniques provide benefits like simpler deployments and operations while addressing challenges like rate of change and device diversity.
- Examples include using pjax for partial page updates over AJAX and client-side includes for caching and reusable content across includes.
This document summarizes an approach to modern web development that separates applications into logical components with single responsibilities. It advocates for building APIs with frameworks like Grails to handle data exchange, separate admin interfaces, and static single page applications using front-end frameworks. Key points include using test-driven development, continuous integration, and pre-generating static content to improve performance and reduce server loads.
Briefly about Drupal and communication. How can we produce data (other than HTML) and receive data. What layers we can use. We mention a lot of things such as XML-RPC
What's behind the hype about Blazor? Is Javascript dead? Another Silverlight? If you are a .Net developer you will love Blazor: the new framework to build web/desktop and even mobile apps with C#. In this talk we will cover Blazor hosting models, Javascript Interop, Components, and a lot more.

Refactoring to a Single Page ApplicationCodemotion
"Refactoring to a Single Page Application" by Marcello Teodori
In origine era il monolite. Spesso dietro una startup web di successo c'è un'applicazione in tecnologia singola (Java, Rails, ecc.) che cresce finché fatica a scalare all'aumentare degli utenti e con essa il relativo processo di sviluppo all'aumentare degli sviluppatori. Sul back-end una strategia consolidata è suddividere progressivamente il monolite in microservice. Per il front-end la soluzione duale è estrarre gradualmente il codice HTML, CSS e JavaScript in una Single Page Application, applicando diverse tecniche come quelle maturate durante la mia esperienza in Workshare.
At the origin there was a monolith. Behind a successful startup often lies a single technology application (Java, Rails, etc.) that grows until it hardly scales with the number of customers and likewise its development process as developers increase. A consolidated strategy on the back-end is to progressively slice the monolith into micro-services. A dual solution on the front-end is to gradually extract HTML, CSS and JavaScript code into a Single Page Application, applying some techniques like the ones I've been maturing during my experience in Workshare.

#RADC4L16: An API-First Archives Approach at NPRCamille Salas
This document discusses NPR's transition to a new digital archives system called Artemis 2.0. It took an API-first approach, developing the backend API first before building out the frontend. Key points discussed include developing a flexible data model, separating the frontend and backend codebases, using a proxy layer for business logic, and lessons learned around documentation, expectations, and migration challenges. The new system provides benefits like increased searchability, flexibility to adapt to growing needs, and more efficient metadata workflows.
Web performance optimization - MercadoLibrePablo Moretti
The document provides techniques and tools for improving web performance. It discusses how reducing response times can directly impact revenues and user experience. It then covers various ways to optimize the frontend, including reducing time to first byte through DNS optimization and caching, using content delivery networks, HTTP compression, keeping connections alive, parallel downloads, and prefetching. It also discusses optimizing images, JavaScript loading, and introducing new formats like WebP. The overall document aims to educate on measuring and enhancing web performance.
Creating a custom API for a headless Drupal involves using the Services module to define endpoints and resources. The Services module introduces endpoints, which define authentication and attach resources. Resources define CRUD operations and custom actions that can target specific resources. To create an API, endpoints and resources are configured through the Services module to expose the desired data and functionality through the custom API.
The document provides an overview of the MEAN stack, which uses JavaScript for full-stack development. It discusses the evolution of web development from separate front-end and back-end work to full-stack JavaScript with Node.js. The MEAN stack combines MongoDB for the database, Express for the web framework, Angular for the front-end, and Node.js as the runtime environment. Each component is introduced, with Node.js using a single-threaded and asynchronous model, Express providing features like routing and middleware, Angular using templates and two-way data binding, and MongoDB as a flexible document database.
This document discusses building APIs and services for mobile apps using Ruby. It provides background on the speaker and history of web and mobile development. It then covers how mobile apps now rely on web APIs to access data, and how building APIs is similar to building web apps but without views. The document discusses designing APIs, testing APIs, and building APIs using various Ruby frameworks like Rails, Sinatra, and the Grape microframework. It emphasizes designing the API interface first before implementation and supporting API versioning for mobile apps.

Web App Prototypes with Google App EngineVlad Filippov
This document discusses using Google App Engine and its Python SDK for quickly prototyping web applications. Some key points covered include:
- App Engine allows developers to build and host web apps and supports Python runtimes. It offers scalable hosting and APIs for common tasks like user auth and data storage.
- The Python SDK makes it easy to quickly create prototypes by providing a local development server, a scalable datastore, and APIs that handle common tasks so developers can focus on unique features.
- Examples of prototyping tasks demonstrated include adding entities to the datastore, building basic views and filters, and testing the prototype. Frameworks like webapp2 and appengine-rest-server can further accelerate the prototyping process
This document discusses using PHP to build a website generator with an intuitive interface for website creation and administration. It describes having sub-pages that can contain different elements like lists of people or projects, and pages made of one or many sub-pages. The technologies used are PHP, MySQL, CSS, JavaScript, and security is added through username/password and encryption. PHP is described as a scripting language especially suited for dynamic web pages that can interact with databases like MySQL. In comparison, PHP is said to be faster than both JSP and ASP.
The document discusses techniques for improving web performance, including reducing time to first byte, using content delivery networks and HTTP compression, caching resources, keeping connections alive and reducing request sizes. It also covers optimizing images, loading JavaScript asynchronously to avoid blocking, and prefetching content. The overall goal is to reduce page load times and improve user experience.

This document discusses different types of caching that can improve performance for PHP applications. It covers opcode caching, which speeds up code execution; data caching using key-value stores like APC, Memcached, and Redis to cache user data; reverse proxy caching with Varnish to cache responses; and browser caching using HTTP headers to cache responses locally. The document provides examples and advantages of each approach. Opcode caches like Zend Optimizer+ and APC compile PHP to bytecode for faster execution. Data caches store user data to reduce database queries. Reverse proxies cache responses for multiple clients. Browser caching improves load times for return visitors.
Google App Engine is a Platform as a Service that allows developers to build and host web applications in Google's data centers. It supports applications written in Java, Python, Go, and PHP. Developers can use App Engine's Datastore for NoSQL storage, Cloud SQL for relational databases, and Cloud Storage for file storage. Additional services like URL Fetch, Mail, and Memcache are also provided. App Engine is suitable for applications that need scalability, don't require access to local files, and can handle requests within 60 seconds.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Editor's Notes
This presentation will provide a high level introduction and overview of the technologies behind progressive web apps: service workers, cache API, IndexedDB, and the manifest file. I’ve decided to structure the presentation in this for at least two reasons I can think of. Firstly, the technologies behind progressive web apps, while not exactly brand new, are not equally implemented in all browsers as yet if at all. Secondly, as a self contained subject progressive web apps is fairly brief, meaning either you know nothing about them at all or pretty much everything there is to know. If I haven’t lost you at this point, good! Let’s continue.
This presentation will provide a high level introduction and overview of the technologies behind progressive web apps: service workers, cache API, IndexedDB, and the manifest file. I’ve decided to structure the presentation in this for at least two reasons I can think of. Firstly, the technologies behind progressive web apps, while not exactly brand new, are not equally implemented in all browsers as yet if at all. Secondly, as a self contained subject progressive web apps is fairly brief, meaning either you know nothing about them at all or pretty much everything there is to know. If I haven’t lost you at this point, good! Let’s continue.
With all that said, why do we care about progressive web apps? Really, what we want is to ensure that neither network connectivity, browser or device choice is a limiting factor for using our web application. In fact, we can go further than this and enhance the app performance for the whole range of network connectivity. At the one end, with ideal network connectivity, we can ensure that the page loads as quickly as possible by fetching locally cached assets instead of fetching them across the network. At the other end, with poor or even no connectivity, we can serve up some experience where this would not have been possible.
More broadly, progressive web apps unlock multiple capabilities such as push notifications and web app display customisation that compete directly with a native app. We can make the move to much more lightweight web app alternatives that much more compelling.
I should also flag up some conflation between progressive web apps and offline-first initiatives. Although progressive web apps enable offline interaction, offline should never be the end goal - we really just care about reliability over flaky network connections. Offline is just a nice add-on, but that won’t stop be using the term!
Also should make clear, this is only considering the current Chrome support
AppCache is just a configuration manifest - problems we have in development simply require us to read documentation. Other problems: forcing updates, reads from cache even if offline etc.
Service workers are again case of code over configuration: can debug, test etc. We have complete control over the experience
Repeatable patterns: exists plugins to save us time of writing from scratch every time
Service workers and cache can be used independently, but together can be effective replacement for AppCache
Moving on to progressive web apps as there are now. The main workhouse are service workers
“Workers” as in run in own thread in browser. A service worker is run in a worker context: it therefore has no DOM access, and runs on a different thread to the main JavaScript that powers your app, so it is not blocking. It is designed to be fully async; as a consequence, APIs such as synchronous XHR and localStorage can't be used inside a service worker.
Both main program and service worker pattern work in event dispatch / event listening
Perhaps no surprise that service workers are fully asynchronous. , APIs such as synchronous XHR and localStorage can't be used inside a service worker.
Access to multiple API such as cache API and fetch API. Will return to cache API later, but for completeness just discuss fetch a bit more here. fetch API is a new alternative to XHR API with full promise support.
Basic idea: service worker acts a programmable proxy server
Because of this, service workers must be served over HTTPS only to prevent man in the middle attacks. Can still develop on localhost - considered secure origin
Lifecycle independent of the page: assets, page, and service worker have separate lifetimes. In fact the service worker has a maximum lifespan of 24hours. We will go into this a bit more soon, but to elaborate, after 24 hours, the browser will look to replace the existing service worker once all
The specific implementation of a progressive web depends very much on the kind of web app you are developing, and the kind of progressive experience you want to enable. For this presentation and the demo, I will consider the case where we have a hard dependency on our assets - we need them for the page to load as expected. If you are interested in other patterns, this link is to an article by Jake Archibald talking about different strategies for both caching and serving assets. In our case, we are going to register the service worker as a progressive enhancement in the main app script. Then in the service worker script, we will declare the resources to cache and well, cache them. On a subsequent page reload, the service worker will step in and serve up the cached assets. Additionally, we can make the further step in our fetch event, we can request missing assets from the network if needs be.
Before looking at some code, let’s look at the service worker lifecycle in a bit more detail
A service worker has a lifecycle that is completely separate from your web page.
To install a service worker for your site, you need to register it, which you do in your page's JavaScript. Registering a service worker will cause the browser to start the service worker install step in the background.
We use eventhandlers to bind the install, activate and fetch events
During the install step, you'll want to cache some static assets. If all the files are cached successfully, then the service worker becomes installed. If any of the files fail to download and cache, then the install step will fail and the service worker won't activate (i.e. won't be installed). If that happens, don't worry, it'll try again next time. But that means if it does install, you know you've got those static assets in the cache.
At the activation step we handle management of old caches, which we'll cover during the service worker update section.
After the activation step, the service worker will control all pages that fall under its scope, though the page that registered the service worker for the first time won't be controlled until it's loaded again. Once a service worker is in control, it will be in one of two states: either the service worker will be terminated to save memory, or it will handle fetch and message events that occur when a network request or message is made from your page.
Only ever one service worker in control of a page at one time, if there is already an active service worker for a given page, a new service worker is queued in the waiting state. Once all instances of the current web app are closed, the old service worker is prepped for deletion and the new worker is activated.
A new service worker is required usually due to some update to the service worker script. We can force a service worker update through basic cache invalidation e.g. changing the name of our assets cache.
Downloaded at least every 24 hours
From project code:
Implementation in sw.js
sw.js can only have scope of files either in the immediate directory it is placed in or subdirectories. For this reason it is typical to place service at project root. It may be preferable in development to place the service worker, then at build time move it to project root
Discuss `filesToCache` array
Discuss event listeners
Register in js/app.js
Progressive enhancement
Can specify scope - this limits files service workers can access
I’m now going to demonstrate this behaviour in the browser
Service worker installation event
Refresh cache storage to show update cache
Service worker fetch
Service worker response
Showw offline
Application > Cache > Cache Storage > static cache name (specified in sw.js)
Application > Service workers > toggle “Update on reload”
Installing a new service worker - will automatically if service worker changed, e.g. versioning assets
We are using localstorage to store todos, and cache API for static assets
Browsers have hard limit as to how much disk space is made available to a given origin - should ensure that caches are frequently purged
A single origin can have multiple cache objects, collected under the CacheStorage API
As of Chrome 46, the Cache API will only store requests from secure origins, meaning those served over HTTPS.
More flexible than AppCache
Service workers have no persistent state - require indexedDB to support multiple service workers
LocalStorage does not support query language
Transactions good for dealing with problems that may arise from multiple instances across multiple tabs. Transactions are atomic.
Transaction scope is defined when it is initialised and fixed for the lifetime of the transaction. This to prevent possible overlap with multiple writes to the same object store. This is designed to prevent race conditions.
Include link tag in main HTML file
It is a best practice to place the manifest link on all your site’s pages, so it will be retrieved by Chrome right when the user first visits, no matter what page they land on.
Demo with GIF
DevTools: Toggle force upload in sources tab - force new service worker install event on cmd-r/ctrl-r
Use serviceworker-internals to debug failing installations
Available as CLI and chrome plugin - audits page to show presence of service worker, 200 status when offline, and other useful metrics
Service workers have been around since 2013
All these are still in progress
Achieve good performance even with full page reloads (server reloads) without javascript
Stream are a big deal in front end web development nowaday. Identity streams: stream resources in the background without requiring javascript
Navigation preload: quicker network response time, at same time as service worker boot up
Service-worker-navigation-preload header
Foreign fetch: dedupe third party requires via service worker
Background fetch: solve issues caused by background sync, higher visibility
