# sails-arangodb
Provides easy access to `ArangoDB` from Sails.js & Waterline.
Take a look at
sails-arangodb-demo for more up-to-date examples.
This module is a Waterline/Sails adapter, an early implementation of a
rapidly-developing, tool-agnostic data standard. Its goal is to
provide a set of declarative interfaces, conventions, and
best-practices for integrating with all sorts of data sources.
Not just database s-- external APIs, proprietary web services, or even hardware.
Strict adherence to an adapter specification enables the (re)use of
built-in generic test suites, standardized documentation, reasonable
expectations around the API for your users, and overall, a more
pleasant development experience for everyone.
This adapter has been developed pretty quickly and may contain bugs.
### Installation
To install this adapter, run:
```sh
$ npm install sails-arangodb
```
### Usage
This adapter exposes the following methods:
###### `find()`
###### `create()`
###### `update()`
###### `destroy()`
###### `createGraph()` # Create a Named Graph
###### `neighbors()` # Experimental, method signature is subject to change
###### `createEdge()` # Experimental, method signature is subject to change
###### `deleteEdge()` # Experimental, method signature is subject to change
### Connection
Check out **Connections** in the Sails docs, or see the `config/connections.js` file in a new Sails project for information on setting up adapters.
in connection.js
```javascript
localArangoDB: {
adapter: 'sails-arangodb',
host: 'localhost',
port: 8529,
user: 'root',
password: 'CgdYW3zBLy5yCszR',
database: '_system'
collection: 'examplecollection' // ArangoDB specific
}
```
### Schema for Graphs
#### Defining a Named Graph in the Schema
```
/*jshint node: true, esversion: 6*/
'use strict';
const Waterline = require('waterline');
const UsersProfilesGraph = Waterline.Collection.extend({
identity: 'users_profiles_graph',
schema: true,
connection: 'arangodb',
attributes: {
// this is a named graph
$edgeDefinitions: [
{
collection: 'users_profiles',
from: ['users_1'],
to: ['profiles_1']
}
]
}
});
module.exports = UsersProfilesGraph;
```
If a model has an attribute called `$edgeDefinitions` then the model becomes a named
graph. Any further attributes are ignored.
[See tests](tests/) for further examples.
### Unit Testing
To run unit-tests every time you save a change to a file, simply:
```
$ gulp
```
One off run of sails-arangodb specific tests (same as above):
```
$ gulp test # or mocha
```
(Important: you must create a test.json file for your local db instance first - see [test/README.md](test/README.md))
To run the waterline adapter compliance tests:
```
$ gulp waterline
```
Generate api jsdocs:
```
$ gulp docs
```
(these are also generated in the default 'watch' mode above)

### Example model definitions
```javascript
/**
* User Model
*
* The User model represents the schema of authentication data
*/
module.exports = {
// Enforce model schema in the case of schemaless databases
schema: true,
tableName: 'User',
attributes: {
id: {
type: 'string',
primaryKey: true,
columnName: '_key'
},
username: {
type: 'string',
unique: true
},
email: {
type: 'email',
unique: true
},
profile: {
collection: 'Profile',
via: 'user',
edge: 'userCommented'
}
}
};
```
```javascript
// api/models/Profile.js
module.exports = {
tableName: 'profile',
attributes: {
id: {
type: 'string',
primaryKey: true,
columnName: '_key'
},
user: {
model: "User",
required: true
},
familyName: {
type: 'string'
},
givenName: {
type: 'string'
},
profilePic: {
type: 'string'
}
}
}
// api/models/User.js
module.exports = {
tableName: 'user',
attributes: {
id: {
type: 'string',
primaryKey: true,
columnName: '_key'
},
username: {
type: 'string'
},
profile: {
collection: 'profile',
via: 'user',
edge: 'profileOf'
}
}
};
;
```
