# feathers-arangodb  

[![Build Status](https://travis-ci.org/AnatidaeProject/feathers-arangodb.png?branch=master)](https://travis-ci.org/AnatidaeProject/feathers-arangodb)  

[![Dependency Status](https://img.shields.io/david/AnatidaeProject/feathers-arangodb.svg?style=flat-square)](https://david-dm.org/AnatidaeProject/feathers-arangodb)  

[![Download Status](https://img.shields.io/npm/dm/feathers-arangodb.svg?style=flat-square)](https://www.npmjs.com/package/feathers-arangodb)  

  

A [Feathers](https://feathersjs.com) database adapter for [ArangoDB](https://www.arango.org/) using [official NodeJS driver for ArangoDB](https://github.com/arangodb/arangojs).  

  

```bash  

$ npm install --save arangojs feathers-arangodb  

```  

  

> __Important:__ `feathers-arangodb` implements the [Feathers Common database adapter API](https://docs.feathersjs.com/api/databases/common.html) and [querying syntax](https://docs.feathersjs.com/api/databases/querying.html).  

  

> This adapter also requires a [running ArangoDB](https://docs.arangodb.com/3.3/Manual/GettingStarted/) database server.

### Simple Server Example  

```javascript  

import express from '@feathersjs/express';  

import feathers, {HookContext} from '@feathersjs/feathers';  

import cors from 'cors';  

import helmet from 'helmet';  

import compress from 'compression';  

import ArangoDbService, { IArangoDbService, IOptions, AUTH_TYPES } from 'feathers-arangodb'  

import { aql } from "arangojs";  

  

// Set up your feathers app.  

const app = express(feathers());  

app.use(helmet());  

app.use(cors());  

app.use(compress());  

app.use(express.json());  

app.use(express.urlencoded({ extended: true }));  

app.configure(express.rest());  

  

// Create your database settings  

const todoDatabase:IOptions = {  

  collection: 'TODOS',  

  database: 'YOUR_DATABASE_NAME',  

  authType: AUTH_TYPES.BASIC_AUTH,  

  username: 'root',  

  password: 'root',  

};  

// Fast and simple CRUD  

app.use('todos', ArangoDbService(todoDatabase));  

  

// Add in some hooks!  

const todoService = >app.service('todos');  

todoService.hooks({  

  after: {  

    create: [  

      async (context:HookContext) => {  

        // Maybe we want run another AQL query directly on the database.  

        const { database, collection } = await todoService.connect();  

        // Do a query  

        const cursor = await database.query(aql`RETURN LENGTH(${collection})`)  

        // Parse the cursor  

        const count = await cursor.next();  

        // Assign some data to the stuff  

        context.result = {  

          count,  

          data: context.result  

        };  

        return context;  

      }  

    ]  

  }  

});  

  

// Start the app listening  

app.listen(8080);  

console.log('Listening on port 8080');  

```  

  

#### Database Options  



**id** *(optional)* : String : Translated ID key value in payloads. Actual storage in database is saved in the `_key` key/value within ArangoDB. Defaults to `_key`



**expandData** *(optional)* : Boolean : Adapter filters out `_rev` and `_id` from ArangoDB. Setting expandData to true will include these in the payload results. Defaults to `false`



**collection** *(required)* : DocumentCollection | String : Either a string name of a collection, which will be created if it doesn't exist in database, or a reference to an existing arangoDB collection object.



**database** *(required)* : Database | String : Either a string name of a database, which will be created if it doesn't exist on the ArangoDB server, or a reference to an existing ArangoDB database object.



**graph** *(optional)* : Graph | { properties, opts } : Graph options to create a new graph. `name` is required in the properties. [See Documentation](https://docs.arangodb.com/devel/HTTP/Gharial/Management.html#create-a-graph)



**authType** *(optional)* :  String : String value of either `BASIC_AUTH` or `BEARER_AUTH`. Used to define the type of auth to ArangoDB ([see documentation](https://docs.arangodb.com/devel/Drivers/JS/Reference/Database/#databaseusebasicauth)). Defaults to `BASIC_AUTH`



**username** *(optional)* :  String : Used for auth, plaintext username



**password** *(optional)* :  String : Used for auth, plaintext password



**token** *(optional)* :  String : If token is supplied, auth uses token instead of username/password.



**dbConfig** *(optional)* :  ArangoDbConfig : ArangoDB Config file for a new database. [See Documentation](https://docs.arangodb.com/devel/Drivers/JS/Reference/Database/#new-database)



**events** *(optional)* :  Array : FeathersJS Events - [See Documentation](https://docs.feathersjs.com/api/events.html)



**paginate** *(optional)* :  FeathersJS Paginate : FeathersJS Paginate - [See Documentation](https://docs.feathersjs.com/api/databases/common.html#pagination)
