Development Guide

Deepstream development is a great way for you to go into depth about building performant nodeJS applications, and contributions are always welcome with lots of ❤

Contributing to is as simple as:

  1. Downloading nodeJS (10+)
  2. Cloning the repo
  3. Run npm i / yarn install to install dependencies
  4. Make your changes / Add a test
  5. Run npm t / npm run e2e to see if the unit tests all pass

For power users who want to make sure the binary works, you can run sh scripts/ true. You'll need to download the usual node-gyp build environment for this to work and we only support the latest LTS version to compile. This step is usually not needed though unless your modifying resource files or changing dependencies.

Post release sanity test for linux distributions:

  1. access a linux machine

  2. copy over the sanity test using:

curl -O

  1. depending on your distribution, run
  • debian/ubuntu: bash deb
  • centos/aws: bash rpm
  • any linux distro: bash tar
