ITB2019 10 in 50: Ten Coldbox Modules You Should be Using in Every App - Jon Clausen

  1. 1. T E N I N F I F T Y T E N C O L D B O X M O D U L E S 
 Y O U S H O U L D B E U S I N G 
  2. 2. Me: Jon Clausen Senior Software Developer,
 Ortus Solutions Grand Rapids, Michigan
  3. 3. C F M I G R AT I O N S
  4. 4. C F M I G R AT I O N S • Version control for your application's database • Changes to database schema are kept in timestamped files that run in order • Two methods: up and down • Built on the QB ( Query Builder ) module, which is database-agnostic • Excellent for deployments across multiple tiers
  5. 5. C F M I G R AT I O N S : Q U I C K S TA R T box install cfmigrations
 box install commandbox-migrations
 box migrate create AddResetTokenToUsersTable
  6. 6. C F M I G R AT I O N S component { function up( schema ) { schema.alter( "users", function( table ){ table.addColumn( table.string( "resetToken", 75 ).nullable() ); } ); } function down( schema ) { schema.alter( "users", function( table ){ table.dropColumn( "resetToken" ); } ); } }
  7. 7. C B A U T H
  8. 8. C B A U T H • Authentication wrapper for Coldbox • Interception points and standardized conventions • Supertype global methods to allow easy access to authentication info in your handlers, views, and interceptors • Simplifies the task of rewriting the auth mechanisms with every new application
  9. 9. C B A U T H : Q U I C K S TA R T box install cbauth • Specify a userServiceClass in your config/ ColdBox.cfc inside erServiceClass • Implement three methods in your user service class and one method in your user object/entity
  10. 10. C B A U T H // Tests the credentials
 public boolean function isValidCredentials( 
 required string username, 
 required string password 
 ){ var user = retrieveUserByUsername( arguments.username ); if( !isNull( user ) ){ return encryptionService.bcryptMatches( 
 ); } else { return false; } } 
 // retrieves the user to test the credentials public function retrieveUserByUsername( required string username ){ return newEntity().where( 'email', arguments.username ).first(); } 
 // retrieves the user by identifier public function retrieveUserById( required string id ){ return newEntity().find( ); }
  11. 11. C B G U A R D
  12. 12. C B G U A R D • Secure routes and events to logged in users and users with specific permissions with component and function annotations • A simple “secured” annotation on a handler prevents execution from all but authenticated users, while additional annotations will check permissions • Handlers/actions may use combinations of actions to provide granular lockdown control • Authentication failures may be re-routed by module and by type of request ( e.g. AJAX vs UI )
  13. 13. C B G U A R D : Q U I C K S TA R T box install cbguard • Implement two methods in your existing authentication service: hasPermission and isLoggedIn • Configure your Coldbox.cfc with the authentication service and any desired override events • Add additional configuration overrides to any application modules
  14. 14. C B G U A R D moduleSettings = { cbguard = { authenticationService : “SecurityService”, authenticationOverrideEvent : “Main.onAuthenticationFailure”,
 authenticationAjaxOverrideEvent : “BaseAPIHandler.onAuthorizationFailure”,
 authorizationOverrideEvent : “Main.onAuthorizationFailure”,
 authorizationAjaxOverrideEvent : “BaseAPIHandler.onAuthorizationFailure”, } };
  15. 15. C B G U A R D component secured{
 function index( event, rc, prc ){...}
 function create( event, rc, prc ) secured=“User:Create”{...} function update( event, rc, prc ) secured=“User:Edit”{…} ...
  16. 16. C B VA L I D AT I O N
  17. 17. C B VA L I D AT I O N • An oldie but goodie. • Works with a variety of different entities, models, DAOs, etc • Supertype methods to simplify validation in handlers • Global or model-specific constraints may be specified
  18. 18. C B VA L I D AT I O N : Q U I C K S TA R T box install cbvalidation • Add constraints to your config, models or objects • Add validation routines in your handler CRUD methods
  19. 19. C B VA L I D AT I O N this.constraints = { firstName : { required : true }, lastName : { required : true }, password : { required : true }, email : { required : true, validator : "UniqueValidator@cborm" } }; moduleSettings = { cbvalidation = { sharedConstraints = { modifiedTime = { required: true }, modifiedBy = { required: true }, } } };
  20. 20. C B S T O R A G E S
  21. 21. C B S T O R A G E S • Another oldie but goodie. • Provides you with a collection of *smart* interfaces for dealing with common scopes and storage mechanisms ( i.e. - cookies, cache ) • Consistent methods for dealing with all scopes - you can change from SessionStorage to CookieStorage without refactoring code • Cookie Storage handles automatic encryption/decryption • Cache Storage simplifies distributed caching of authentication and “session” persistence
  22. 22. C B S T O R A G E S : Q U I C K S TA R T box install cbstorages • Begin implementing usage in your auth services and other places where storage scopes are used
  23. 23. C B S T O R A G E S component{
 property name=“cookieStorage” inject=“CookieStorage@cbstorages”;
 property name=“sessionStorage” inject=“CacheStorage@cbstorages”;
  24. 24. C B S T O R A G E S function setAuthorizedUser( required User user ){         //set our session storage var         sessionStorage.setVar(             name="AuthorizedUser",             value=arguments.user.getId()         );         // set a cookie which we can use for timeout evaluation         cookieStorage.setVar(             name="AuthorizedUser",             value=arguments.user.getId(),             expires = dateDiff( 'd', now(), dateAdd( 'n', now(), 20 ) )         );         return this; } function logout(){ if( isSessionAuthenticated() ){         sessionStorage.deleteVar( "AuthorizedUser" );         cookieStorage.deleteVar(“AuthorizedUser" ); } }
  25. 25. B C RY P T
  26. 26. B C RY P T • Creates cryptographically strong (and slow) hashes • Implements one-way encryption - can never be decrypted • Usages: Paswords, Pins, API Tokens, etc • Given many recent, very public user/password data thefts, you owe it to yourself to use this one…
  27. 27. B C RY P T : Q U I C K S TA R T box install BCrypt • Add additional configuration options and begin using to secure your passwords
  28. 28. B C RY P T /** * BCrypt a string */ function bCrypt( string value ){     return variables.bCrypt.hashPassword( ARGUMENTS.value ); } /** * Verify if a string matches */ function bCryptMatches( string provided, string stored ){     try{         return variables.bCrypt.checkPassword( provided,stored );     } catch( "java.lang.IllegalArgumentException" e ){         return false;     } }
  29. 29. C B M A I L S E R V I C E S
  30. 30. C B M A I L S E R V I C E S • Object-Oriented email with a consistent interface • Data tokens in views to support dynamic data • Built-in protocols ( CFMail, File-based, Postmark ) • Other protocols available through forge box • Allows for global configuration of sender information • Additional protocols are easily developed
  31. 31. C B M A I L S E R V I C E S : Q U I C K S TA R T box install cbmailservices • Add additional configuration options to your Coldbox configuration
  32. 32. C B M A I L S E R V I C E S var contactMail = mailService.newMail( to=event.getValue( "recipient", getSetting( "mailSettings" ).to ),, subject=rc.subject ); contactMail.setBody( renderView( view=“email/contacts/index" ) ); mailService.send( contactMail );
  33. 33. M E M E N T I F I E R
  34. 34. M E M E N T I F I E R • Transforms objects into data structures • Injects itself in to model objects and can be configured and extended • Exceptionally fast transformations as native functions ( no passing around of objects or collections during transformation)
  35. 35. M E M E N T I F I E R : Q U I C K S TA R T box install mementifier • Add additional memento configuration to your modules
  36. 36. M E M E N T I F I E R this.memento = { // An array of the properties/relationships to include by default defaultIncludes = [ "id", "username", "firstName", "lastName", "email", "avatar" ], defaultExcludes = [], neverInclude = [ "password", "PIN" ], defaults = { "roles" : [], "explicitPermissions" : [] }, mappers = {} };

  38. 38. C F F R A C TA L
  39. 39. C F F R A C TA L • Another tool for rich transformations of data objects • Include and exclude items • Custom serialization, filtering and sanitization of data ( e.g. XML, JSON, Arrays, Maps, etc ) • Prevents repetitive code in your handlers
  40. 40. C F F R A C TA L : Q U I C K S TA R T box install cffractal • Add transformers and serialization handling in your handlers
  41. 41. C F F R A C TA L fractal .builder() .collection( users ) .withTransformer( "UserTransformer" ) .withIncludes( "roles" ) .convert();
  42. 42. C F F R A C TA L event.paramValue( “format”, “json” );
 switch( rc.format ){
 case “xml”:
 var serializer = “XMLSerializer@cffractal”;
 var serializer = “ResultsMapSerializer@cffractal”;
  43. 43. C B S T R E A M S
  44. 44. C B S T R E A M S •  Enable functional-style operations on streams of elements ( e.g. - collections ) • Elements in a stream are processed and passed across the processing pipeline ( e.g. parallel transformations, while maintaining synchronicity ) • Unlike traditional CFML functions like map(), reduce() and filter(), which duplicate, streams maintain the integrity of the original collection • Chainable syntax which mimics native collection member functions
  45. 45. C B S T R E A M S : Q U I C K S TA R T box install cbstreams
  46. 46. C B S T R E A M S return streamBuilder .new( users )
 .map( function( user ){ return {
 “firstName” : user.firstName,
 “lastName” : user.lastName
 } } ) .sorted( function( item1, item2 ){ return item1.lastName.compareNoCase( item2.lastName ); } ) .forEach( function( item ){ item[ “fullName” ]=item.firstName & “ “ & item.lastName; } );
