# Demo React Application using the libsignal-protocol-typescript

## Deployment

To deploy this website to AWS EC2, 

1. launch a EC2 instance. Allow http and https in the security group config. 

2. SSH into the instance, install necessary packages and clone this repository 

```

# Install nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

# Activate nvm

export NVM_DIR="$HOME/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

# Install Node.js version 16.20.0

nvm install 16.20.0

# Install Git and apache2

sudo apt-get update

sudo apt-get install git apache2 -y

# clone the signal demo app if needed

directory_path="./signal-demo"

if [ -d "$directory_path" ]; then

    echo "Directory $directory_path exists"

else

    echo "Directory $directory_path does not exist"

    git clone https://github.com/haochenuw/signal-demo.git

fi

```

3. Build and setup the dependencies. 

Note: if EC2 build fails. Can build locally.  

```

cd signal-demo 

bash setup.sh 

npm run build 

```  

4. Copy the build files into apache2 location 

```

mv -r build /var/www/SignalBuild

```

If not built on EC2, 

```

scp -r build user@ec2-ip:/var/www/SignalBuild 

```

5. Configure apache2 

```

cd etc/apache2/sites-available

sudo mv 000-default.conf 001-signal.conf

```

Then, put the following into the file 001-signal.conf

```

        ServerName https://ec2-54-201-48-228.us-west-2.compute.amazonaws.com/

        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/SignalBuild

        ErrorLog ${APACHE_LOG_DIR}/error.log

        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SSLEngine on

        SSLCertificateFile /etc/apache2/certs/apache.crt

        SSLCertificateKeyFile /etc/apache2/certs/apache.key

```

6. Setup SSL config (note: this is required for crypto functionalities to work)

```

sudo apt-get install openssl

sudo a2enmod ssl

sudo a2enmod rewrite

sudo mkdir /etc/apache2/certs

```

Then, go into /etc/apache2/apache2.conf and change the section to look like this: 

```

        Options Indexes FollowSymLinks

        AllowOverride ALL

        Require all granted

``` 

Then, generate a self-signed cert

```

cd /etc/apache2/certs

sudo openssl req -new -newkey rsa:4096 -x509 -sha256 -days 365 -nodes -out apache.crt -keyout apache.key

```

7. start service 

```

sudo systemctl restart apache2

```

To verify it works, go to the public IP of your EC2 instance.
