This a dummy project, to play with various technologies :

• finatra
• bootstrap
• highcharts & highstock for timeseries
• dropzone
• elasticsearch
• elastic4s
• better-files

quick starts

• sbt run starts the server which listens on 0.0.0.0:8888

git clone https://github.com/dacr/finatra-dummy.git
sbt run

run in place in developer mode

As soon as something changes, finatra restarts...

sbt '~re-start'
sbt '~re-start -maxRequestSize=500.megabytes'

ps : brought to us thanks to https://github.com/spray/sbt-revolver sbt plugin

Packaging and quick in-place run

sbt assembly
./runit.sh

./runit.sh -help to view options.

  sysctl -w net.ipv4.ip_local_port_range="5000 65535"
  sysctl -w net.ipv4.tcp_tw_reuse=0
  sysctl -w net.ipv4.tcp_tw_recycle=0
