Symfony2 - global templating variables in PHP renderer with ChillDevViewHelpersBundle

Thursday, 16 June 2016, 10:47

Short time ago, while working on one of my projects i faced a problem with PHP templating engine in Symfony2 (again the same) - passing pre-defined variables to view renderer. For some reason it's not possible to define global variables for PHP templating engine. It is possible for Twig (with TwigBundle), but there is no equivalent of that for PHP. After googling for a moment and browsing some of Stack Overflow questions I ensured myself that it's not possible and that I'm not the only one who is looking for such a feature.

Deploying Lambda@Edge with pl.wrzasq.lambda

Thursday, 22 November 2018, 13:12

When working with cloud, one of the most efficient approaches you can leverage is serverless architecture. This concept allows you to define your entire application as set of interacting resources, without worrying about underlying infrastructure. Serverless applications can scale virtually to infinity, are cost-effective, lower maintenance costs (forget about patching kernels, installing system packages, defining upgrade paths etc.). Per-se, serverless it is a general pattern, but I will focus on AWS as this is my area of expertise - here, the main computing unit in serverless world is Lambda. It is a FaaS component that allows you to run your piece of code "in the cloud", which means decoupled form any computing hardware. Such code pieces can be triggered by you to perform some computation, but can also act as a handlers for various events across the platform (like SNS message processors, API Gateway authorization handlers and many many more). One of such integration ways is Lambda@Edge, which allows for handling CloudFront request events.

FrontPageFilter - SPA with server side pages in Java

Thursday, 06 October 2016, 20:29

Time flies, browsers become more and more modern, they are more and more up-to-date. As the common web standards and new frontend technologies are being adopted you can shift more stuff to the client-side. Particularily it means nowadays you can leave most of the frontend part on your JavaScript application shoulders. Thanks to that SPA approach is getting more and more popular. Especially that most search engines and webmaster tools are now able to understand and execute JavaScript code to build full site representation for analysis. With all of these in mind it's an attractive idea to develop your backend application as a pure JSON API (it doesn't have to be pure REST) and handle everything related to presentation layer on a frontend (browser) side. But you still need an application to serve it all from your server(s). Which means your backend application still needs to be a web application.

Symfony2 - simple, yet useful tips

Thursday, 16 June 2016, 10:47

It's been a while since my last article and activity, as I was mainly concentrated on my private life and commercials projects, but even though my top commitment was updating projects dependencies on GitHub I also experimented with some different approaches for organising Symfony2 projects. I want to share some of my thoughts, so you may also benefit from using it or tell me why these ideas are stupid. I don't want to write here some obvious stuff like "write unit tests", "use Composer" etc. - you can read that in every single tutorial for Symfony2. Some of my tricks are plain simple but not obvious, some, on the other hand look strange, but saved my ass, so you can give them a try. Please excuse my a bit chaotic form (and content), but I'm writing this in my free time while commuting by train :P.
