Loads and provides NEDB connections

nedb-service loads NEDB dat abases from a folder and provides connections. It flushes the DB connections every hour.

The lib provides singleton persistent connections, which can be used in different modules of the application.

Synopsis

// Init in your `index.js`
const dbService = require("@popovmp/nedb-service");
dbService.init(path.join(__dirname, "db-folder"), ".db");

// Use in all other files
const pageDb = dbService.getConnection("page");

pageDb.fineOne({author: "popov"}, {_id: 0},
   pageDb_findOne_ready);

function pageDb_findOne_ready(err, data) {
   console.log(JSON.stringify(data));
}

Installation

npm install @popovmp/nedb-srevice

Logging errors

nedb-service uses the micro-logger ( https://npmjs.com/package/@popovmp/micro-logger ) package for logging errors.

When micro-logger is not initialized, it logs in the console. If you want to log the errors in a log file, init micro-logger in your index.js as follows;

const logger = require("micro-logger").init("./logs/log.txt");

Methods

nedb-service exports two methods:

/**
 * Initialize the DB Service
 * Reads the DB files and sets a connection for each of them
 *
 * @param {string} dbDirectory - directory containing the DB files
 * @param {string} dbFileExt - DB files extension (including the dot)
 */
function init(dbDirectory, dbFileExt)

/**
 * Gets a connection to a DB
 *
 * @param {string} dbName
 * @returns {DataStore}
 */
function getConnection(dbName)
