Create your own Covid-19 data tracker

posted in JavaScript on 2020-03-30   covid-19 tracker virus api zeit covid https data github data tracker thevirustracker time johns hopkins university code back end endpoints react created recharts beginning tags tag link countries package sh https c19stats

I'm continuing to experiment with React and TypeScript. The weekend-long project this time was a Covid-19 data tracker. In this blog post I will share how I built c19stats.now.sh. I exposed the data as a public API at the same URL. I guess you, as many other people, follow the situation so you may want to glue your fingers on the keyboard and create something useful around the data. I got lots of fun playing with the diagrams.

VSCode go to definition/implementation fixed

posted in JavaScript on 2020-01-17   vscode typescript intellisense problem implementation working common fixed definition

I just spent ~2 hours on this and I had to blog about it. I bet I will come back to the same problem and it will be nice to have a quick solution at hand. And the problem that I'm talking about is the non working Go to definition or Go to implementation feature of VSCode. Or in other words the JavaScript IntelliSense was not working for me. Of course it was annoying because I had to navigate to files manually via the folder tree on the left or typing the name of the file in the Cmd+Shift+P popup.

Running Prettier for specific Git branch

posted in Architecture on 2020-01-14   prettier git bash script branch file awk print echo file awk run prettier line column file mode files project

I'm working on a project in my own git branch. At the end of my working day I want to do one thing - run Prettier so my code is nicely formatted before I submit the PR for code review. Of course I know about the VSCode Prettier extension but right now my editor is kinda broken and I don't want to mess with it. I'm still on my branch and I run Prettier from the terminal. All good but the amount of changes that happened is so big that my 50+ loc updates are like a needle in a haystack. It is like that because apparently there are already malformatted files in the project. It is definitely not possible to understand what I did because of so much noise. So ... I want to run Prettier but only on the files that I touched in that particular branch.

Start your own JavaScript library using webpack and ES6

posted in JavaScript on 2015-12-30   library js webpack babel true var file module exports eslint function build

Two months ago I published a starter pack for React based on webpack. Today I found out that I need almost the same thing but without the React bit. This simplifies the setup but there are still some tricky parts. So, I made a brand new repository webpack-library-starter and placed all the stuff that we need for creating a JavaScript library.

Node.js Blueprints book - second chapter's clarification

posted in Nodejs on 2014-07-30   express version book app chapter node js blueprints var bodyparser code

Before a couple of months my first book Node.js Blueprints was published by Packt. There are a couple of reviews in Amazon about chapter two. It’s about Express. One of the most popular frameworks in the Node.js ecosystem. The book mentions version 3.0 but the truth is that the code samples are for version 4.0. I feel that I still have to point out the differences and mark these parts of the chapter that are not valid for the newest version of the library.

Why we should think about our CSS

posted in Architecture on 2012-06-05   css browsers block rendering tv device ratio print tv device g print tv e g print browsers download css page browsers download white page browsers experience white page

_The evil that CSS do:- Browsers block rendering until all CSS arrives. With the worst possible experience: white page.- Browsers download CSS they don't need, e.g. print, tv, device-ratio... And most browsers block rendering because of these too- Sometimes CSS blocks the other downloads too (not just block rendering, but block images and scripts that follow) - when followed by an inline SCRIPT or when it's a CSS in conditional comment for IE_Read the full artcile by Stoyan Stefanov here.

AS3: converting XML to JSON object

posted in ActionScript on 2011-04-02   label url image xml id img cdata node var version xml2json class http site int childnode object

I'm absolutely sure that you are using external data in your flash/flex applications. It is a good practice to transfer information in XML format. Most of the projects that I'm working on also use XML and in most of them I have a class that converts the data to JSON object. The problem with this workflow is that the parser's logic is always different because the XML is different. These days I wrote a class that solved this problem and directly converted every given XML file to a JSON object.
