[erseco]

This commit migrates the console commands from Symfony to NestJS using the NestCommander library. The migration includes:

New Files

CLI Infrastructure

• src/cli.ts: CLI entry point using CommandFactory
• src/commands/command.module.ts: Main command module with TypeORM integration

JWT Commands

• src/commands/jwt/generate-jwt.command.ts: Generate JWT tokens with custom claims
• src/commands/jwt/validate-jwt.command.ts: Validate and decode JWT tokens

User Management Commands

• src/commands/user/create-user.command.ts: Create new users in the database
• src/commands/user/user-role.command.ts: Manage user roles (add/remove/list)
• src/commands/user/generate-api-key.command.ts: Generate API keys for users

Maintenance Commands

• src/commands/maintenance/database-test.command.ts: Test database connectivity
• src/commands/maintenance/validate-providers.command.ts: Validate provider configuration (stub)

Documentation

• CLI_COMMANDS.md: Comprehensive documentation for all CLI commands with usage examples

Modified Files

Dependencies

• package.json: Added nest-commander, jsonwebtoken, and related type definitions
• package.json: Added npm scripts for CLI execution (cli, cli:prod)

Commands Migrated (7/18)

✅ Migrated Commands:

• app:jwt:generate
• app:jwt:validate
• app:create-user (alias: app:add-user)
• app:user:role (aliases: app:user:promote, app:user:demote)
• app:generate-api-key
• app:database-test
• app:validate-providers (stub - requires ProviderConfigurationService migration)

⏳ Pending Migration (11 commands):

• Export commands (8): elp:convert, elp:export, elp:export-{elp,html5,html5-sp,ims,scorm12,scorm2004,epub3}
• app:translations:extract
• app:tmp-files:cleanup
• elp:convert

Technical Details

• All commands use NestCommander decorators (@command, @option)
• Proper dependency injection with TypeORM repositories
• Consistent error handling with appropriate exit codes
• Support for all original command options and arguments
• Commands follow NestJS module structure for better maintainability

Breaking Changes

None - Symfony commands remain available in symfony_legacy/ directory

Future Work

The export commands require migration of the following services first:

• OdeService and OdeExportService
• FileHelper and file management services
• Format-specific exporters (HTML5, SCORM, IMS, EPUB)

See CLI_COMMANDS.md for complete usage documentation.
