Workflow ES


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.

Installing

``

* Javascript (ES6)
* Typescript

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)*
* MongoDB
(more to come soon...)*

$3

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.

#### Queue Providers

SingleNodeQueueProvider (Default built-in provider)*
* Azure
* Redis


#### Distributed lock managers

SingleNodeLockProvider (Default built-in provider)*
* Azure
* Redis Redlock
