# install mongodb using brew
brew install mongodb

# create the folder where mongo will store its data
mkdir -p /usr/local/var/mongodb

# ensure this data directory has the correct permissions
sudo chown -R `id -un` /usr/local/var/mongodb

# mongodb stores its configuration file under /usr/local/etc/mongod.conf
# check this file to confirm the dbPath has been set correctly, or to get this value in the future
cat /usr/local/etc/mongod.conf

# should give output similar to this:
systemLog:
  destination: file
  path: /usr/local/var/log/mongodb/mongo.log
  logAppend: true
storage:
  dbPath: /usr/local/var/mongodb
net:
  bindIp: 127.0.0.1

brew install yarn

# start local mongodb instance in a shell window
mongod -dbpath /usr/local/var/mongodb

# in a different shell window navigate to the root of this repository and run the following command:
yarn install

# run the application
npm start

# or to run watch on the file system:
npm run watch
