Setup instructions

The following instructions will help you to get ready for Le Wagon fullstack bootcamp:

  • Grab a text editor, where you'll spend your day and nights
  • Install a package manager
  • Pimp your Terminal
  • Setup git and GitHub
  • Install Ruby

GitHub account

Have you signed up to GitHub? If not, do it right away.

Upload a picture and put your name correctly on your GitHub account. This is important as we'll use an internal dashboard with your avatars.

Sublime Text 3 - Your text editor

A text editor is one of the most important tools of a developer. Follow these instructions in the Terminal:

sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install -y sublime-text-installer

Sublime Text is free without any time limitation but a popup will appear every ten saves to remind you there is a license to buy. You can hit Esc when this happens, but feel free to buy Sublime Text if you really like this one (there are alternatives).

Git

Download git, the versioning program we'll use every day to archive our code:

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install -y git

Oh-my-zsh - Fancy your Terminal

We will use the shell named zsh instead of bash, the default one.

sudo apt-get install -y zsh curl vim nodejs imagemagick jq
curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh > install.sh && bash install.sh && rm install.sh
# it will ask for your session password

Be careful, those commands will ask you to type your password twice. At the end your prompt should look like this:

If it doesn't, ask a teacher.

To make this change stick, restart your laptop or virtual machine:

sudo shutdown -r 0

GitHub

We need to generate SSH keys which are going to be used by GitHub and Heroku to authenticate you. Think of it as a way to log in, but different from the well known username/password couple. If you already generated keys that you already use with other services, you can skip this step.

Open a terminal and type this, replacing the email with yours (the same one you used to create your GitHub account). It will prompt for information. Just press enter until it asks for a passphrase.

NB: when asked for a passphrase, put something you want (and that you'll remember), it's a password to protect your private key stored on your hard drive. You'll type, nothing will show up on the screen, that's normal. Just type the passphrase, and when you're done, press Enter.

mkdir -p ~/.ssh && ssh-keygen -t rsa -C "[email protected]"

Then you need to give your public key to GitHub. Run:

cat ~/.ssh/id_rsa.pub

It will prompt on the screen the content of the id_rsa.pub file. Copy that text, then go to github.com/settings/ssh. Click on Add SSH key, fill in the Title with your computer name, and paste the Key. Finish by clicking on the Add key green button.

To check that this step is completed, in the terminal run this. You will be prompted a warning, type yes then Enter.

ssh -T [email protected]

If you see something like this, you're done!

# Hi --------! You've successfully authenticated, but GitHub does not provide shell access

If it does not work, try running this before trying again the ssh -T command:

ssh-add ~/.ssh/id_rsa

Don't be in a rush, take time to read this article to get a better understanding of what those keys are used for.

Dotfiles (Standard configuration)

Hackers love to refine and polish their shell and tools. We'll start with a great default configuration provided by Le Wagon, stored on GitHub. As your configuration is personal, you need your own repository storing it, so you first need to fork it to your GitHub account.

➡️ Click here to fork the lewagon/dotfiles repository to your account. Forking means that it will create a new repo in your GitHub account, identical to the original one. You'll have a new repository on your GitHub account, your_github_username/dotfiles. We need to fork because each of you will need to put specific information (e.g. your name) in those files.

Open your terminal. Don't blindly copy paste this line, replace replace_this_with_your_github_username with your own github usernickname.

export GITHUB_USERNAME=replace_this_with_your_github_username

# Example:
#   export GITHUB_USERNAME=ssaunier

Now copy/paste this very long line in your terminal. Do not change this one.

mkdir -p ~/code/$GITHUB_USERNAME && cd $_ && git clone [email protected]:$GITHUB_USERNAME/dotfiles.git

Run the dotfiles installer.

cd ~/code/$GITHUB_USERNAME/dotfiles
zsh install.sh

Then run the git installer. It will prompt you for your name and your email.

Be careful, you need to put the same email as the one you sign up with on GitHub.

cd ~/code/$GITHUB_USERNAME/dotfiles
zsh git_setup.sh

Please now quit all your opened terminal windows.

Sublime Text auto-configuration

Open a new terminal and type this:

stt

It will open Sublime Text in the context of your current folder. That's how we'll use it.

Wait 1 minute for additional packages to be automatically installed (New tabs with text will automatically open, containing documentation for each new package installed).

To check if plugins are installed, open the Command Palette (⌘ + ⇧ + P on OSX, Ctrl + ⇧ + P on Linux), type in Packlist and then Enter, you should see a couple of packages installed (like Emmet).

If you don't, please install all of them manually. The list is referenced here.

Installing Ruby (with rbenv)

First we need to clean up any previous Ruby installation you might have:

Open a Terminal, and run:

if [ -x "$(command -v rvm)" ]; then rvm implode && sudo rm -rf ~/.rvm; fi
if [ -d ~/.rbenv ]; then sudo rm -rf ~/.rbenv; fi

Then in the terminal, run:

sudo apt-get install -y build-essential tklib zlib1g-dev libssl-dev libffi-dev libxml2 libxml2-dev libxslt1-dev libreadline-dev
sudo apt-get clean
sudo mkdir -p /usr/local/opt && sudo chown `whoami`:`whoami` $_
git clone https://github.com/rbenv/rbenv.git /usr/local/opt/rbenv
git clone https://github.com/rbenv/ruby-build.git /usr/local/opt/rbenv/plugins/ruby-build
source ~/.zshrc

You should get a warning in the prompt, just ignore it from now (Ruby is not installed yet).

Now, you are ready to install the latest ruby version, and set it as the default version.

Run this command, it will take a while (5-10 minutes)

rbenv install 2.3.1

Once the ruby installation is done, run this command tell the system to use the 2.3.1 version by default.

rbenv global 2.3.1

Then restart your Terminal (close it and reopen it).

ruby -v

You should see something starting with ruby 2.3.1p. If not, ask a teacher.

Installing some gems

gem install bundler rspec rubocop pry pry-byebug hub colored

Never install a gem with sudo gem install! Even if you stumble upon a Stackoverflow answer (or the Terminal) telling you to do so.

Postgresql

In a few weeks, we'll talk about SQL and Databases and you'll need something called Postgresql, an open-source robust and production-ready database. Let's install it now.

sudo apt-get install -y postgresql postgresql-contrib libpq-dev build-essential
echo `whoami` > /tmp/caller
sudo su - postgres
psql --command "CREATE ROLE `cat /tmp/caller` LOGIN createdb;"
exit
rm -f /tmp/caller

Check-up

Let's check if you successfully installed everything.

Quit all opened Terminal, open a new one and run the following commands:

curl -Ls https://raw.githubusercontent.com/lewagon/setup/master/check.rb | ruby

It should tell you if your workstation is ready :) If not, ask a teacher.

Alumni

Register as a Wagon alumni by going to alumni.lewagon.org/onboarding. Select your batch, sign in with GitHub and enter all your information.

Your teacher will then validate that you are indeed part of the batch. You can ask him to do it as soon as you completed the registration form.

Once the teacher has approved your profile, go to your email inbox. You should have 2 emails:

  • One from Slack, inviting you to the Le Wagon Alumni slack community (where you'll chat with your buddies and all the previous alumni). Click on Join and fill the information.
  • One from GitHub, inviting you to lewagon team. Accept it otherwise you won't be able to access the lecture slides.

Slack

Download the Slack native app from the Slack page. In Linux (Beta) section, choose Ubuntu 64-bit and download it.

Then install it:

cd ~/Downloads
sudo dpkg -i slack-desktop-*.deb

Launch the app and sign in to lewagon-alumni organization.

Make sure you upload a picture there.

You can also sign in to Slack on your iPhone or Android device!

The idea is that you'll have Slack open all day, so that you can share useful links / ask for help / decide where to go to lunch / etc.

Enjoy your ride with Le Wagon :)
