NeDB Adapter

update

• 升级nedb版本
• 修改数据时可以使用$inc
• 修复sails-nedb中每次重启后id就改变的问题

Waterline adapter for NeDB.

A persistent object store which uses Node Embedded Database as the storage engine.

Caution

In case you run multiple sails workers on a machine as part of a load balancing strategy: NeDB is not designed to synchronize file writes across multiple concurrent processes. Running an NeDB-backed sails app with more than 1 worker WILL eventually lead to inconsistent, and very likely corrupted data.

Installation

Install from NPM.

$ npm install @laomu/sails-nedb --save

The NeDB dependency is actually pulled from my forked repo of the original, because I needed to add aggregation support at the DB layer. If and when this pull request gets merged into the main line, the dependendency will be switched back to the npm module.

Sails Configuration

Add the nedb config to the config/connections.js file. No special configuration is necessary. One can optionally set the filePath to point to a particular location. Files get saved to .tmp inside the application root by default.

Acknowledgement

A big thanks to the contributors of NeDB, sails-disk, and sails-mongo. This adapter owes its existence in no small amount to each of these projects :).

About Waterline

Waterline is a new kind of storage and retrieval engine. It provides a uniform API for accessing stuff from different kinds of databases, protocols, and 3rd party APIs. That means you write the same code to get users, whether they live in mySQL, LDAP, MongoDB, or Facebook.
