A very small node module that provides basic access to the activiti process engine (http://activiti.org)) using the node java bridge (see https://github.com/joeferner/node-java).
This module is a result of some experiments with the node platform.
Trying out the useful node java bridge to leverage java libraries in node.
As a show case I have chosen the activiti process engine so that I can use executable bpmn models in node.
(an alternative way to use activiti is by using its REST-API, however this module provides a way to use activiti embedded).
npm install activiti --save
In general, the first step is to configure activiti (data store, users, etc.). For example, access to a h2 database can be configured as follows.
activiti.configure({
processEngineName : "myEngine",
jdbcUrl: "jdbc:h2:tcp://localhost/c:/myDB",
jdbcUsername: "sa",
jdbcPassword: "sa",
});COnfiguration is useful to define a druable data store for activiti because if no configuration is provided, a h2 in memory database will be used and tables will be automatically created and dropped.
After configuration a process engine is created and the activiti API can be used.
The following example reads the list of all process definitions.
// access the activiti library
var activiti = require('activiti');
// use the repository service to access process definitions
var repository = activiti.repositoryService(),
// query all deployed process defintions
var processes = repository.createProcessDefinitionQuerySync().listSync();
console.log("Deployed Processes : " + processes.sizeSync());npm test
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code.
- 0.1.0 Initial release Based on Activiti 5.14
