# feathers-ottoman
[](https://github.com/bwgjoseph/feathers-ottoman/blob/master/LICENSE)
[](https://www.npmjs.com/package/feathers-ottoman)
__IMPORTANT__: This is still in early development stage, please report any issue found
This library is written against [ottoman-2.2.1](https://github.com/couchbaselabs/node-ottoman) and is tested against [Couchbase 7.1.1](https://docs.couchbase.com/server/7.0/introduction/intro.html) which supports [scope and collection](https://docs.couchbase.com/server/7.0/learn/data/scopes-and-collections.html)
---
A [Feathers](https://feathersjs.com) database adapter for [Ottoman](https://ottomanjs.com/), an object modeling tool for [Couchbase](https://www.couchbase.com/)
```bash
$ npm install feathers-ottoman
```
> __Important:__ `feathers-ottoman` 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 Couchbase](https://docs.couchbase.com/tutorials/getting-started-ce/index.html) database server
## API
### `service([options])`
Returns a new service instance initialized with the given options. `Model` has to be a `Ottoman` model. See the [Ottoman Guide](https://ottomanjs.com/guides/schema.html#defining-your-schema) for more information on defining your model
```js
// commonjs
const service = require('feathers-ottoman');
// es6 / typescript
import { service } from 'feathers-ottoman';
app.use('/messages', service({ Model }));
app.use('/messages', service({ Model, id, events, paginate, ottoman: { lean, consistency } }));
```
__Options:__
- `Model` (**required**) - The Ottoman model definition
- `id` (*optional*, default: `'id'`) - The name of the id field property. Note that the `id` has to be also define when initializing the `Ottoman Model` if not using default value
- `events` (*optional*) - A list of [custom service events](https://docs.feathersjs.com/api/events.html#custom-events) sent by this service
- `paginate` (*optional*) - A [pagination object](https://docs.feathersjs.com/api/databases/common.html#pagination) containing a `default` and `max` page size
- `whitelist` (*optional*) - A list of additional query parameters to allow
- `multi` (*optional*) - Allow `create` with arrays and `update` and `remove` with `id` `null` to change multiple items. Can be `true` for all methods or an array of allowed methods (e.g. `[ 'remove', 'create' ]`)
- `ottoman.lean` (*optional*, default: `true`) - Runs queries faster by returning plain objects instead of `Ottoman Model`
- `ottoman.consistency` (*optional*, default: `NONE`) - Define default [Search Consistency Strategy](https://docs.couchbase.com/server/current/learn/services-and-indexes/indexes/index-replication.html#index-consistency)
> **Note:** You can get access to the Ottoman model via `this.Model` inside a [hook](https://docs.feathersjs.com/api/hooks.html) and use it as usual. See the [Ottoman Guide](https://ottomanjs.com/guides/schema.html#defining-your-schema) for more information on defining your model
## Example
Here is an example of a Feathers server with a `messages` Ottoman service
```
$ npm install @feathersjs/feathers @feathersjs/express ottoman feathers-ottoman
```
In `index.js`:
```js
// Initialize Ottoman connection
const { Ottoman, getModel, Schema, SearchConsistency } = require('ottoman');
const ottoman = new Ottoman();
ottoman.connect({
connectionString: 'couchbase://localhost',
bucketName: 'messageBucket',
username: 'user',
password: 'password',
});
const modelOptions = {
// specify `idKey` if not using default
// idKey: 'customId',
scopeName: 'messageScope',
collectionName: 'messageCollection',
};
const schema = new Schema({
text: { type: String },
});
ottoman.model('message', schema, modelOptions);
ottoman.start();
// Setup feathers service
const feathers = require('@feathersjs/feathers');
const express = require('@feathersjs/express');
const { Service } = require('feathers-ottoman');
// Creates an ExpressJS compatible Feathers application
const app = express(feathers());
// Parse HTTP JSON bodies
app.use(express.json());
// Parse URL-encoded params
app.use(express.urlencoded({ extended: true }));
// Host static files from the current folder
app.use(express.static(__dirname));
// Add REST API support
app.configure(express.rest());
// Register a Ottoman message service
app.use('/messages', new Service({
Model: getModel('message'),
// if `idKey` is specify for the Model
// id: 'customid',
ottoman: {
lean: true,
consistency: SearchConsistency.LOCAL,
},
paginate: {
default: 10,
max: 100
}
}));
// Register a nicer error handler than the default Express one
app.use(express.errorHandler());
// Create a dummy Message
app.service('messages').create({
text: 'Message created on Ottoman server'
}).then(function(message) {
console.log('Created messages', message);
});
app.listen(3030).on('listening', () => console.log('feathers-ottoman example started'));
```
Run the example with `node .` and go to [localhost:3030/messages](http://localhost:3030/messages)
For a complete example, take a look at [feathers-ottoman-demo](https://github.com/bwgjoseph/feathers-ottoman-demo) repository
## Development
### Setup
1. Run `docker-compose up -d`
2. Wait 5-10 sec for all services to fully initialized
3. Launch a command prompt and run `docker exec -it feathers-couchbase bash`
4. Once inside the container, run `cd scripts` then `./setup-couchbase.sh`, type `y` if prompted. See details below
5. You can now access couchbase via `localhost:8091` and login using `admin:password`
#### setup-couchbase script
This script will initialize and setup couchbase node and cluster using the couchbase-cli, hence, no manual setup is required. It will:
1. Initialize the node with `admin:password` credentials
2. Initialize the cluster with only `data, index, query, fts` services enabled
3. Create `user:password` with `full admin` rights
4. Creates a bucket: `testBucket`
5. Creates a scope: `testpostscope` under `testBucket`
6. Creates a collection: `testpostcollection` under `testpostscope`
7. Creates index on `testBucket` and `testBucket.testpostscope.testpostcollection`
## Release
1. Update `package.json and package-lock.json` version
2. Run `logchanges`
3. Commit `CHANGELOG.md` [chore: update CHANGELOG for X.X.X]
4. Commit `package.json and package-lock.json` [X.X.X]
5. Git tag `vX.X.X`
6. Run `npm publish --dry`
7. Run `npm publish`
8. Git push
9. Create new release in Github
