tl;dr In this post I’ll try to show what, in my opinion, are the current pain points on the common ways to do ssr in React, comparing existing solutions in a didactic way.

First of all, what’s SSR?. SSR is the acronym for server side rendering. On a high level, this means generating the complete web page on the server without having to rely on the client side javascript.

We won’t enter into details of why we’d want to do this, but, it can be mainly motivated by SEO concerns, accessibility or just performance.

This is a round up of the first talk I did called “No metas todo en la misma bolsa: generando bundles por dispositivo” (which could be translated to the title of this article).

This is the second post in a series where I explain how to encapsulate the specific device logic into a Razzle plugin:

tl;dr; the idea is to reduce the needed boilerplate in order to serve particular experiences for each device.

This post will be more code related, I’ll show…


Some months ago the company where I work introduced a new policy called bring your own device (BYOD). Although, many already had set up the company’s google mail on our phone for free, now we were encouraged to use our personal device to work, but in order to do so, we had to install a Google App Device Policy.

My first step was opening gatsby tutorial. Although, I must admit that the people from gatsby did a great work writing the docs, it seems to be targeted to new comers, i just…


Tl;dr; In the post i’ll show how to pass custom command line arguments to test suits run by Jest framework.

Lately i’ve using Tescafe for doing some end to end test (for those who doesn’t know, it is a Node.js tool to automate end-to-end web testing) and i’ve really like the proposed way to deal with configuration.

Basically, Tescafe has this question in their faq: How do I work with configuration files and environment variables? in which they just tell you “use an argument parser library to parse custom commands”.

This is the first post in a series where I explain how to build a react progressive web application that targets specific devices constraints:

tl;dr; the idea is to incrementally start serving particular experiences for each device (i.e: Mobile / Desktop) in the lazy programming way.
