That right there is the power of community tooling backing an abstraction like GraphQL. In this article, Sandip Devarkonda will explore what GraphQL is, and then take it for a spin by building a poll app in which users can vote and on-screen aggregated results are updated in real time.

Overusing inline CSS or JS code, as opposed to serving code through static resources, can harm the site’s performance. In this article, Leonardo Losoviz will learn how to load dynamic code through static files instead, avoiding the drawbacks of too much inline code. You will see, as an example, how WordPress loads 43kb of scripts to print the Media Manager, which are pure JavaScript templates and could perfectly be loaded as static resources.

When creating a multi-step form in which a file is uploaded and manipulated, if the application is running on several servers behind a load balancer, then we need to make sure that the file is available all throughout the execution of the process, for whichever server handles the process at each step. In this article, Leonardo Losoviz will solve this issue by creating a repository accessible to all servers where to upload the files, based on AWS S3.

While effective bundling of resources on the web has received a great deal of mindshare in recent times, how we ship front-end resources to our users has remained pretty much the same. The average weight of JavaScript and style resources that a website ships with is rising — even though build tooling to optimize the website has never been better. With the marketshare of evergreen browsers rising fast and browsers launching support for new features in lockstep, is it time we rethink asset delivery for the modern web? Today, Shubham Kanodia will give you some answers.

Dealing with this in JavaScript can be tricky. But what if instead of fight against it we could leverage on it to achieve nice stuff like function composition with virtual methods? This is what Willian Martins is going to explore in this article about one of the potential upcoming JavaScript features: The Bind Operator. The goal here is to add some hype around it and create awareness of the hard work that TC39 is doing to find consensus, fix all the syntax and semantics issues and have it shipped with the next releases of ECMAScript.
