Juniper Tech OS Handlers

These are the handlers that tie into various events inside of the Juniper Tech Ingstion Stack. These are meant to be small functions that handle specific tasks. Each package requires...

• Dockerfile
• Devspace yml config
• .env file

Each handler needs to accept these env variables:

• topic (the event topic to subscribe to)
• kafka url

Getting Started

We use docker to start development infrastructure, it is required to have running before you can begin developing the server side portion of the application. This is a nodejs ingestion server that interfaces with a separate database, this server doesn't handle sensor onboarding, only ingestion of data at the moment. In the future, device onboarding and management will be moved either to this repository or a separate repository.

Development

• Install dependencies with yarn install
• devspace (yarn global add devspace)
• run docker volume create timeseries-db-volume
• run docker-compose up -d to make sure services have started

Only needed for package publishing

• run lerna link && lerna bootstrap to symlink cross dependencies
