Display Javascript console logs with jsfiddle

Jsfiddle is mainly made to test javascript code in a web context (aka with HTML and CSS). But, if you just want to use is to test backend code, you probably want to see results in the console. This can be done by adding the following library to your project :

Install Microsoft Visual Studio Code on a chromebook

My chromebook is fantastic! As it supports Linux integration feature, I can open a terminal and install every Debian based packages I want such as Microsoft Visual Studio Code. Let's go!


Step 1 - Import the Microsoft GPG key :

curl -sSL https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

Step 2 - Add the Visual Studio Code repository :

sudo add-apt-repository "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main"

Step 3 - Install the latest version of Visual Studio Code

sudo apt update
sudo apt install code

That's all!

Install Node.js on a chromebook

If you have a chromebook which supports Linux experimental integration feature (look for this in your global parameters), then you can open a bash terminal. The Linux behind the scene seems to be Debian based.

So, to install Node.js, forget the classic way with sudo apt-get install nodejs because you will get an old release. Instead of that, you can to this :

Step 1 – Add Node.js PPA

sudo apt-get install curl software-properties-common
curl -sL https://deb.nodesource.com/setup_12.x | sudo bash -

Step 2 – Install Node.js

sudo apt-get install nodejs

That's all!

Self upgrade of npm and node.js

Even I'm an old Java developer, I'm a newbie on node and npm and it's a new playground for me.

My project is to product some JS code (maybe TypeScript). As every software architect, my first question was : how to structure, package and deliver my project. This is done with npm (the package manager from node.js).

I've got npm on my laptop (installed with a classic sudo apt-get install npm) but I realized it's an old release.

Hopefully, node.js echosystem is great and everything can be self upgraded. Thus, you don't need any new debian package.  Great! Let's'do this :

# Let's upgrade node.js to the last stable release 
sudo npm cache clean -f
sudo npm install -g n
sudo n stable

# Then, we upgrade npm
sudo npm install npm@latest -g

# If your npm -v doesn't return the new version, you sould have multiple npm executable in your path
# On my Ubuntu, I changed the symbolic link
sudo ln -sf /usr/local/bin/npm /usr/bin/npm

That's all!

Remove ugly bash (shell) directory highlight colors

Tired of green over blue colors in default Ubuntu shell for directories ?

Just type this from your shell console to update your bash profile :

echo -e "\nLS_COLORS=\$LS_COLORS:'ow=1;33' ; export LS_COLORS\n" >> ~/.bashrc

Enjoy:)
