Couchbase Mobile<\/span><\/a> is the NoSQL database solution for mobile. It has an embedded NoSQL database (Couchbase Lite), built-in synchronization (Sync Gateway), and is all backed by a highly scalable and performant<\/span> NoSQL database server (Couchbase Server). <\/span>\u00a0<\/span><\/p>\n\n\n\n

With the recent announcement that <\/span>Parse<\/span><\/a> will be shutting down indefinitely, developers are left to figure out how to migrate \u00a0their Parse mobile applications to another technology.<\/span><\/p>\n\n\n\n

Below is a simple example of how you can migrate an existing Parse app to Couchbase Mobile, backed by <\/span>Digital Ocean<\/span><\/a>. <\/span><\/p>\n\n\n\n

Storing data in Couchbase Mobile is similar as storing data in Parse. \u00a0The key-value pairs in the ‘ParseObject’ is equivalent to a document in Couchbase. \u00a0On Android, let us compare the code between writing data in Parse versus writing data in Couchbase Lite. : <\/span><\/p>\n\n\n\n

Here\u2019s an example of writing data in Parse:<\/span><\/p>\n\n\n\n

ParseObject gameScore = new ParseObject("GameScore");\r\ngameScore.put("score", 0129);\r\ngameScore.put("playerName", "SooA Lim");\r\ngameScore.put("cheatMode", false);\r\ngameScore.saveInBackground();\r\n<\/code><\/pre>\n\n\n\n
Here\u2019s an example of writing data in Couchbase Lite:<\/span><\/p>\n\n\n\n
Map<String, Object> gameScore = new HashMap<String, Object>();\r\ngameScore.put(\u201cscore", \u201c0129");\r\ngameScore.put(\u201cplayerName", \u201cSooA Lim");\r\ngameScore.put(\u201ccheatMode", \u201cfalse");\r\ndocument.putProperties(gameScore);<\/code><\/pre>\n\n\n\n
As you see from this example, usage patterns in Parse and Couchbase Mobile are quite similar.<\/span><\/p>\n\n\n\n
Synchronization<\/h3>\n\n\n\n
From a datastore perspective, Couchbase Mobile is a more complete solution. Couchbase is a full-stack database with integrated synchronization and security, and includes features like conflict resolution, events, REST API, Stream and Batch API, and more. Parse was limited in these types of capabilities. \u00a0\u00a0<\/span><\/p>\n\n\n\n
Here are some more examples of how you use the Couchbase Mobile database in your mobile code:<\/span><\/p>\n\n\n\n
\/\/ Get the database (and create it if it doesn\u2019t exist).\r\nManager manager = new Manager();\r\nDatabase database = manager.getDatabase("mydb");\r\n\r\n\/\/ Create replicators to push & pull changes to & from the cloud.\r\nURL url = new URL("\u201dhttps:\/\/www.my.com\/mydb\/");\r\nReplication push = database.createPushReplication(url);\r\nReplication pull = database.createPullReplication(url);\r\npush.setContinuous(true);\r\npull.setContinuous(true);\r\n\r\n\/\/ Add authentication.\r\nAuthenticator authenticator = AuthenticatorFactory.createBasicAuthenticator(name, password);\r\npush.setAuthenticator(authenticator);\r\npull.setAuthenticator(authenticator);\r\n\r\n\/\/ Listen to database change events.\r\ndatabase.addChangeListener(this);\r\n\r\n\/\/ Start replicating.\r\npush.start();\r\npull.start();\r\n\r\n\/\/ Create a new document (i.e. a record) in the database.\r\nDocument document = database.createDocument();\r\nMap<String, Object> properties = new HashMap<>();\r\nproperties.put("firstName", "John");\r\ndocument.putProperties(props);                                                                                                                                                                                                                                                                                                                                                                                                                                                <\/code><\/pre>\n\n\n\n
