“Oh, I heard you are a programmer. Can you help me to create a site?”

Almost every year, I get into a situation when I need to set up a new javascript project. Projects with a modern framework like Angular already configured for us. But what about more simple apps or widgets, which should be framework agnostic? Usually, we need to have: a liver-reload, TypeScript, CSS-preprocessor, a framework for unit testing, and linter. This guide will be about building a production-ready starter kit, which will satisfy all our requirements.

Generating PDF files is one of the most used features in SaaS projects. I even saw people ask the Firebase team on Twitter to implement an extension for this functionality.

Cloud Functions for Firebase is a serverless framework that lets you run backend code in response to events and HTTPS requests. Our JavaScript or TypeScript code is stored in Google’s cloud and runs in a managed environment.

Google just announced some updates for Google Chrome on Android devices. One of the updates is Floom. It’s an amusing tool, which shows in augmented reality the hole through the Earth near you. So you can see what is on the other side of the planet from the place where you are standing right now.
