Dead simple data store. In-memory with persistence to file.
This is a Dead Simple Data Store for Node.js. It's an in-memory data store that automatically persists to file (unless you tell it not to). dsds does not care about speed, security, ACIDity and what not. It's meant for those experiments and quick scripts where you just want to store some data in the easiest and quickest way possible.
It uses synchronous functions just so that you don't have to write a callback.
npm install dsds --save
var dsds = ;
Creates a new data store with the name
name. If you call
the same name again, you will get the cached object so you can access
the same store from different parts of your code.
idProperty: String. This is the name of the property where the ID will be stored in. Default: "id";
persistence: Boolean. Whether the data should be persisted to file. Default: true
autoPersist: Boolean: Whether the data should be automatically persisted on every write operation. Default: true. You can manually call
filePath: String. Path to the file where the data should be persisted. Default:
'./' + name + '.json'. The directories will be automatically created if necessary.
var store =;
Returns the object with the ID
property argument is passed, the corresponding property value of
the record is returned.
var ryu = store;var ryuHeight = store;
property argument is passed this sets the property
the record with ID
id and returns the new property value.
property argument is omitted, this will behave exactly like
var newHeight = store;
Returns an array containing all records.
var fighters = storeall;
data in to the store. And resturns the new object. A unique ID
will be added to the property defined in
var ryu = store;console;
Updates a record and returns the updated record.
data will be merged
in to the existing record and leave the other properties intact.
var id = 'ce4c05cd-00fc-410d-9f17-209b543e232f';var ryu = store;
Replaces a record and returns the new record. Leaves the ID intact.
var id = 'ce4c05cd-00fc-410d-9f17-209b543e232f';var evilRyu = store;
Deletes the record with ID
var id = 'ce4c05cd-00fc-410d-9f17-209b543e232f';store;
Returns an array of all records that pass the test in
filter function internally.
var females = store;
store.find but returns only the first record. Uses lodash's
find function internally.
Writes all records to disc. You don't have to call this manually unless
you have set
Loads the data from
options.filePath. You don't have to call this
