The document discusses state management in web applications using Redux and MobX. It presents a call center management app to demonstrate both approaches. Redux uses actions, reducers, and middleware for state management with a defined data flow. MobX uses decorators to automatically manage state with less code but less testability. Best practices include connecting only smart components to the store and using the store for reusable data. While Redux is more complex and testable, MobX is more automatic but "magical".

Kanban - Establish a Delivery Rhythm
Kanban - Establish a Delivery RhythmAvarteq This document discusses establishing efficient delivery rhythms in agile software development projects using Kanban. It notes that fixed delivery rhythms with timeboxing can cause inefficiencies. Kanban uncouples delivery from prioritization and development cycles. Delivery costs include coordination costs between teams and transaction costs of delivering software. The document recommends defining a delivery rhythm based on these costs and the business value. It suggests increasing the delivery rhythm and reducing coordination and transaction costs to improve delivery efficiency.

Serverless architecture: focus on code, performance and costs
Serverless architecture: focus on code, performance and costsLaura La Manna Serverless architecture focuses on code, performance, and costs. It decreases concern over infrastructure management and allows developers to focus on business logic. With serverless, there is no infrastructure to manage, resources auto-scale with no wasted resources, and customers only pay for what they use. However, serverless architectures are not truly cost-free or without limits. Performance, costs, code portability, and standards are important factors to consider when determining if serverless is appropriate.

From Zero to Serverless (DogFoodCon 2018)
From Zero to Serverless (DogFoodCon 2018)Chad Green So many times our customers need a simple routine that can be executed on a routine basis but the solution doesn’t need to be an elaborate solution without going the trouble of setting servers and other infrastructure. Serverless computer is the abstraction of servers, infrastructure, and operating systems and make getting solutions to your customer’s needs much quicker and cheaper. During this session we will look at how Azure Functions will enable you to run code on-demand without having to explicitly provision or manage infrastructure.
Cloud-native Data: Every Microservice Needs a Cache
Cloud-native Data: Every Microservice Needs a Cachecornelia davis Presented at the Pivotal Toronto Users Group, March 2017
Cloud-native applications form the foundation for modern, cloud-scale digital solutions, and the patterns and practices for cloud-native at the app tier are becoming widely understood – statelessness, service discovery, circuit breakers and more. But little has changed in the data tier. Our modern apps are often connected to monolithic shared databases that have monolithic practices wrapped around them. As a result, the autonomy promised by moving to a microservices application architecture is compromised.
With lessons from the application tier to guide us, the industry is now figuring out what the cloud-native architectural patterns are at the data tier. Join us to explore some of these with Cornelia Davis, a five year Cloud Foundry veteran who is now focused on cloud-native data. As it happens, every microservice needs a cache and this evening will drill deep on that topic. She’ll cover a variety of caching patterns and use cases, and demonstrate how their use helps preserve the autonomy that is driving agile software delivery practices today.

Lets go to the background
Lets go to the backgroundRan Wahle This document discusses background operations in web applications including background sync, periodic background sync, and background fetch. Background sync allows sending data whenever the network is available, periodic background sync gives the feeling of constant connection to the server even when offline, and background fetch allows downloading content from the network without stopping when the network throttles or stops. These background operations help make the user experience less dependent on the network status.
Permissions api
Permissions apiRan Wahle The document discusses the new Permission API which provides a unified way for websites to query, request, and revoke user permissions and handle changes. It allows developers to know the permission status without asking, and be notified of changes. Some permissions like camera and accelerometer may not work the same way yet as it is still an experimental API. Links are provided for the specification, MDN documentation, a polyfill, and demo code.
Lets go vanilla
Lets go vanillaRan Wahle The presentation discusses the evolution of browsers, JavaScript, and frameworks. It argues that while frameworks provide useful features like data binding and routing, they can also lock developers into certain approaches. Reinventing the wheel with vanilla JavaScript is possible using browser APIs and standards like custom elements, attributes, events, and the History API. Programming directly with vanilla JavaScript ensures familiarity with underlying capabilities and flexibility to choose the best tools.

Web workers 
Web workers Ran Wahle Web workers allow JavaScript to run in background threads to optimize performance. A worker runs in a separate global context and can communicate with the main thread via messaging. A shared worker can serve multiple browsing contexts and uses ports to send and receive messages between contexts. Workers parallelize work to speed up tasks while shared workers facilitate sharing state across contexts by using a single worker instance.
Using legacy code with micro frontends
Using legacy code with micro frontendsRan Wahle Ran Wahle discusses using micro frontends to integrate legacy code into a modern single page application (SPA) in a peaceful way. A demo is shown integrating three sample applications - one using jQuery, one using Angular 6, and one using Angular 5 and Firebase. Micro frontends allow each application to have its own URL routing and inner routing while reusing backend services. Wrapping applications as custom elements is also discussed as an alternative to iframes for less isolation while still maintaining independence. The talk concludes that micro frontends can help extend legacy code and blend applications together to achieve "world peace" between new and old approaches.

Our story about on-going migration from angularJs to Angulat
Javascript async / await Frontend-IL
Javascript async / await Frontend-ILRan Wahle The document discusses async/await in JavaScript. It explains that async/await allows writing asynchronous code that looks synchronous by using the await keyword to "turn" a promise into its resolved value. Async functions always return promises, even though code below await reads synchronously. Async/await simplifies code by avoiding callback nesting and is supported in modern browsers.
Angular 2.0 change detection
Angular 2.0 change detectionRan Wahle The document discusses Angular 2.0 change detection. It describes how Angular 2.0 change detection is more efficient and predictable compared to Angular 1.x by using a component-based approach rather than a graph. Each component has its own change detector that is generated at compile time. Change detection occurs top-down via the change detection tree. The document also discusses strategies like OnPush, immutable objects, observables, and manually controlling change detection.
Code migration from Angular 1.x to Angular 2.0
Code migration from Angular 1.x to Angular 2.0Ran Wahle Front-end.IL session about making your AngularJs 1.x code ready for andular 2.0 and mirgating using the UpgradeAdapter module.
Async patterns in javascript
Async patterns in javascriptRan Wahle The document discusses various asynchronous patterns in JavaScript, including using events, callbacks with Socket.IO, promises, observables, iterators, generators, and async/await. It provides code examples for promise creation, using the Fetch API, ES2015 iterators, and TypeScript's async/await syntax. The presentation aims to demonstrate asynchronous patterns for event handling, promises, iterators/generators, and async/await in TypeScript and Angular 2.
Angular js 2
Angular js 2Ran Wahle AngularJs 2.0 introduces components as the fundamental building blocks, replacing directives. The presentation covers getting started with AngularJs 2.0, including dependencies, configuration, components, data binding, services, routing and migration from Angular 1. It emphasizes that Angular 2 is a rewrite built on newer standards to improve performance and reduce opinionation. Migration involves componentizing the application and using an upgrade adapter to support a hybrid Angular 1 and 2 app.
Asyncawait in typescript
Asyncawait in typescriptRan Wahle The document summarizes a presentation about using async/await to write asynchronous JavaScript code in a synchronous style. It begins with an introduction to promises as the standard pattern for asynchronous programming. It then demonstrates how async/await allows writing asynchronous code that looks synchronous using async functions and the await keyword. Under the hood, async/await uses generators produced by the TypeScript compiler. The presentation includes code examples and demos of geolocation and reverse geocoding using promises and async/await. It concludes with additional resources for learning more about iterators, generators, and async/await.
Angular%201%20to%20angular%202
Angular%201%20to%20angular%202Ran Wahle Angular 2.0 introduces significant changes from Angular 1.x including a new component-based architecture, use of TypeScript for static typing, and improved performance. The document discusses how to prepare Angular 1.x applications for migration by refactoring into components and using TypeScript. It also provides an overview of key differences in Angular 2.0 like bootstrapping, data binding, dependency injection and services.
What’s new in angular 2 - From FrontEnd IL Meetup
What’s new in angular 2 - From FrontEnd IL MeetupRan Wahle This document provides an overview of the key differences between Angular 1.x and Angular 2.0. Angular 2.0 introduces components, new data binding, and dependency injection based on newer standards like ES6. Components are classes with templates and metadata, replacing directives. Data binding uses property and event binding instead of two-way binding. Change detection is enhanced for performance. Angular 2.0 apps are bootstrapped differently by creating and bootstrapping components instead of modules.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)
What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.
