# Process Builder Improvements ## Overview This document outlines the planned improvements for the Process Builder core components. The improvements are designed to be manageable and maintainable while adding essential functionality. ## Variable System ### 1. Global Variables ```javascript { name: 'string', type: 'string|number|boolean|object|array', defaultValue: any, description: 'string', scope: 'global', isRequired: boolean, isReadOnly: boolean } ``` ### 2. Process Variables ```javascript { name: 'string', type: 'string|number|boolean|object|array', defaultValue: any, description: 'string', scope: 'process', isRequired: boolean, isReadOnly: boolean, direction: 'in|out|inout' // for process arguments } ``` ### 3. Task/Form Arguments ```javascript { name: 'string', type: 'string|number|boolean|object|array', defaultValue: any, description: 'string', direction: 'in|out|inout', isRequired: boolean, validation: { rules: [], customValidation: 'string' // custom validation script } } ``` ## Core Components Improvements ### 1. Start Event ```javascript { type: 'start', data: { description: 'Process start point', triggerType: 'manual', // manual, scheduled schedule: null, // for scheduled triggers variables: { input: [], // process input arguments output: [] // process output arguments }, globalVariables: [] // global variables used in this process } } ``` ### 2. End Event ```javascript { type: 'end', data: { description: 'Process end point', resultType: 'success', // success, error variables: { input: [], // variables required for end event output: [] // variables to be returned }, returnValues: [] // values to return to calling process } } ``` ### 3. Task ```javascript { type: 'task', data: { description: 'A general task', assignee: '', taskType: 'manual', // manual, automated priority: 'medium', // low, medium, high dueDate: null, variables: { input: [], // task input arguments output: [] // task output arguments }, notifications: { onAssign: true, onComplete: true } } } ``` ### 4. Form Task ```javascript { type: 'form', data: { description: 'Form submission task', formId: null, formName: null, formSettings: { allowDraft: true, autoSave: true }, variables: { input: [], // form input arguments output: [] // form output arguments }, dataMapping: { input: [], // map process variables to form output: [] // map form to process variables } } } ``` ### 5. Gateway ```javascript { type: 'gateway', data: { description: 'Decision gateway', conditions: [], defaultPath: 'Default', gatewayType: 'exclusive', // exclusive, parallel variables: { input: [], // variables needed for conditions output: [] // variables to pass to next node }, timeout: { enabled: false, duration: 0 } } } ``` ## New Core Components ### 1. Script Task ```javascript { type: 'script', data: { description: 'Execute custom script', scriptType: 'javascript', script: '', variables: { input: [], // script input arguments output: [] // script output arguments }, timeout: 30 // seconds } } ``` ## Implementation Priority ### Phase 1 - Essential Improvements 1. Implement basic variable system - Global variables - Process variables - Task/Form arguments 2. Add basic trigger types to Start Event 3. Add result types to End Event 4. Add task priorities and due dates 5. Add form settings for drafts and auto-save ### Phase 2 - Enhanced Features 1. Add variable validation system 2. Add data mapping for forms 3. Add script task component 4. Add timeout handling 5. Add notifications system ### Phase 3 - Advanced Features 1. Add subprocess component 2. Add advanced gateway conditions 3. Add process templates 4. Add process versioning 5. Add process analytics ## Variable System Features ### 1. Variable Types - String - Number - Boolean - Object - Array - Date - File - Custom types ### 2. Variable Scopes - Global (accessible across all processes) - Process (accessible within a process) - Task/Form (accessible within a task/form) - Local (accessible within a script) ### 3. Variable Operations - Create/Delete - Read/Write - Copy/Move - Transform - Validate - Persist ### 4. Variable Passing - Process to Process - Task to Task - Form to Process - Script to Process - Gateway Conditions ## Notes - Keep improvements focused on essential functionality - Maintain backward compatibility - Ensure easy maintenance - Document all new features - Add proper validation - Include error handling - Implement proper variable scoping - Add variable type checking - Include variable persistence ## Future Considerations - Process templates - Process versioning - Process analytics - Advanced notifications - Custom validations - Process documentation - Process testing - Process deployment - Variable encryption - Variable versioning - Variable dependencies Last updated: June 10, 2024
