Workflow ES is a workflow / saga library for Node.js (or modern browsers). It supports pluggable persistence and concurrency providers to allow for multi-node clusters.
Install the core npm package "workflow-es"
npm install workflow-es --save
Since workflows are typically long running processes, they will need to be persisted to storage between steps. There are several persistence providers available as seperate npm packages.
- Memory Persistence Provider (Default provider, for demo and testing purposes)
- (more to come soon...)
By default, the WorkflowHost service will run as a single node using the built-in queue and locking providers for a single node configuration. Should you wish to run a multi-node cluster, you will need to configure an external queueing mechanism and a distributed lock manager to co-ordinate the cluster. These are the providers that are currently available.
