The synonyms feature in ElasticSearch is very powerful, but just like most of the ElasticSearch features, it hides complexities and subtleties that might be hard to understand at a first glance.

Synonyms bridge the gap between relating concepts and ideas (i.e. “England”, “UK”) or between slightly different vocabulary usage (like British English “colour” vs. American English “color”) in the documents and queries, which …

At work we started to use Next.js for a new project. So far the experience has been nothing but positive, however recently we hit one of the limitations of the framework. We wanted to inject data, fetched from an API, in all the pages during build time. Specifically we wanted to fetch Feature Flags from our dedicated service into Next.js, in order to conditionally render new features.

You would think that this requirement would be easily covered by Next.js, but …

In this post I want to integrate the previous article with the approach that I used during the deployment of one of my latest Elixir side-projects. Keep …

This post started as a simple guide on how to configure the Fastify web framework to run inside a Google Cloud Function, but its focus quickly switched to a deeper analysis on the authentication to Google Cloud Functions (GCF from now on).

GCF is the FaaS (Function as a Service) platform provided by Google. It’s a serverless execution environment for building and connecting cloud services. With Cloud Functions you write simple, single-purpose functions that are …
