Introduction ======== This is a node.js driver for OrientDB using the OrientDB binary protocol. Installation ======== ``` npm install orientdb ``` As developer you should fork/clone this repo and once you have it on your machine, do the following in your repo directory: ``` npm install ``` Versioning ========== In order to make it clearer what OrientDB version is supported we will the following versionning scheme: `x.y.z`, where `x.y` is the the OrientDB major and minor version. For example: - when OrientDB releases version `1.3.0` we will start publishing versions `1.3.z` - when OrientDB version `1.4.0` is out, we will start publishing 1.4.z versions The `z` part of our version is **our internal** patch number for that OrientDB release. This will be used using the [semantic versioning (semver)](http://semver.org/) rules. For example: - before an OrientDB release (say `1.5.0`), we will use versions like `1.5.0-alpha1` or `1.5.0-beta1` - by the time OrientDB releases version `1.5.1`, we are probably further with the patch number `z` (say `1.5.3`) due to bug correction, forgotten features, etc. To test OrientDB `1.5.1` we will start using versions like: `1.5.4-beta1`, where our `1.5.4` version will correspond to the OrientDB release `1.5.1`. Is this clear? ;) Tutorial ======== To start using OrientDB and nodejs, check out the ["Blog Tutorial"](https://github.com/gabipetrovay/node-orientdb/wiki/Blog-Tutorial-with-ExpressJS-and-OrientDB). Status ======== This OrientDB driver is almost mature now, but we are still testing it. While we use it in production already and therefore it implements a sufficient number of features for making a fully featured application, we recommend you make some thorough tests before you do it as well. If you find any problems, let us know such that we can improve things. Until version 1.0 we also don't guarantee any backwards compatibility and API stability since we are trying things out. But 1.0 should not be far from now. The following commands are not implemented yet (just pick one and send us a pull request): * RECORD_CHANGE_IDENTITY * RECORD_CLEAN_OUT * POSITIONS_FLOOR * POSITIONS_CEILING * PUSH_RECORD * PUSH_DISTRIB_CONFIG * DB_COPY * REPLICATION * CLUSTER For a more complete list, check out the [Driver Compatibility Matrix](#driver-compatibility-matrix) Supported database versions ======== We test each release against the following OrientDB versions: 1.1.0, 1.3.0. We've had to drop OrientDB 1.2.0 support because of this [issue](https://github.com/nuvolabase/orientdb/issues/949). If you're using 1.2.0, we strongly encourage you to evaluate 1.3.0. Testing ======== An OrientDB Graph Edition server instance must be running. Use the [test configuration files](https://github.com/gabipetrovay/node-orientdb/tree/master/config/test) to provide data to the tests about the running instance (user, port, etc.). Then run: `npm test` to run all the tests under `test`, or `node test/db_open_close.js` to run a specific test. And make sure all run before you make a pull request. NOTE: The `test/z_shutdown.js` will shutdown the server. So make sure it's the last one to run. (i.e. Don't add a test that is after this one in Lexicographical order.) Connecting to a database ======== ```javascript var orient = require("orientdb"), Db = orient.Db, Server = orient.Server; var dbConfig = { user_name: "admin", user_password: "admin" }; var serverConfig = { host: "localhost", port: 2424 }; var server = new Server(serverConfig); var db = new Db("temp", server, dbConfig); db.open(function(err) { if (err) { console.log(err); return; } console.log("Database '" + db.databaseName + "' has " + db.clusters.length + " clusters"); // use db.command(...) function to run OrientDB SQL queries }); ``` Changes ======== See [ChangeLog](https://github.com/gabipetrovay/node-orientdb/blob/master/ChangeLog) Driver Compatibility Matrix ======== The following table list all the commands exposed by OrientDB. It's here to help you helping us: just pick one of the not yet implemented commands and send us a pull request. Each command has a JS API if it's already supported, or a "not yet implemented" if not. It also has a Yes/No/Not yet label under each supported OrientDB versions: commands may be implemented but may be available only with recent OrientDB.
