Setup a development enviroment for SpeakIT

This guide assumes you want to use a virtual machine instead of messing around in your host operative system, it is especially useful if you are using a windows computer.

But the same dependecies are required regardless of what OS you are using so the instructions here should be somewhat relevant anyway.

Install a new virtual machine with Ubuntu

Download virtualbox for your current OS https://www.virtualbox.org/wiki/Downloads

Download the latest Ubuntu LTS .iso image from https://ubuntu.com/download/desktop

Now create a new virtual machine and install ubuntu, google if you need futher instructions.

Log into the machine

First lets update the machine.

$ sudo apt update
$ sudo apt upgrade

The machine might need a restart after this.

The machine is missing some of our dependencies so let's install them.

Install git

$ sudo apt install git

Install any decent editor, e.g. vscode or emacs

Go to https://code.visualstudio.com/docs/setup/linux and download the .deb package install it via the command

$ cd ~/Downloads && sudo apt install ./<file>.deb

Now you should be able to search for and open vscode in your VM.

Now we are going to install our other dependecnies

The frontend part of SpeakIT is built with yarn, the easiest way to install is via the node pakcage manager, so install npm first using:

$ sudo apt install npm

Ather this we can install yarn with npm

$ sudo npm install --global yarn

The backend is built with go so lets install go with the instructions at https://golang.org/doc/install

Download the tar-ball "Download go for linux"
Extract the archive you downloaded into /usr/local, creating a Go tree in /usr/local/go using the following command

$ sudo tar -C /usr/local -xzf go1.16.4.linux-amd64.tar.gz

Edit your .profile file in your home directory and add the following line to the end of that file

export PATH=$PATH:/usr/local/go/bin

From your terminal run the following command $ source ~/.profile
Now $ go version should return the version you just installed

SpeakIT can also use docker and docker-compose for development so lets install them.

$ sudo apt install docker-compose

Clone the repo and build/run

First we need to set a GOPATH variable, e.g. you could set it in a directory called go in your home directory:

$ cd ~
$ mkdir go

Now set the variable in your .profile by adding the following line

export GOPATH=~/go

And run the following command:

$ source ~/.profile

Now we clone our repo into our GOPATH-directory

$ git clone https://github.com/cthit/speakIT $GOPATH/src/github.com/cthit/speakIT

Since SpeakIT started before go modules you need to modify go to be able to build the backend without complaining. This can be done with the following command. $ go env -w GO111MODULE=auto

Now run the following the download the rest of the dependencies

$ cd $GOPATH/src/github.com/cthit/speakIT
$ (cd backend; go get -d)
$ (cd frontend; yarn)

When this is done the application can be started

Running backend $ (cd backend; go install) && $GOPATH/bin/backend
Runnig frontend $ (cd frontend; yarn start)
