Setting Up

Server

Before proceeding server make sure you have installed MongoDB and the mongo daemon is running.

Once you have setup MongoDB, install npm dependencies.

cd server
npm install

Launch development server by running,

npm start

For production use we recommend using forever.

npm install -g forever
forever start ./utils_scripts/foreverConfig.json

While bootstrapping the database administrator account can be created as follows,

node util_scripts/addAdmin.js

The default administrator credentials are "admin:admin".

Client

To launch the client, we must first install electron. We recommend installing electron globally.

npm install -g electron

Once electron is installed, proceed to download Anaconda installers. Please note that installers for all supported operating systems is downloaded during this step and consume up to 10GB of memory.

cd client
./download_conda.sh

The client app can be launched in development mode via,

npm start

To create a binary for the client first install electron-packager.

npm install -g electron-packager

To build artifacts simply run,

./build_app.sh

Note: MacOS artifacts should be created on Mac machines only.
