Mongo collections dumper

This is lightweight utility that allows you to easily dump and restore mongo collections. No mongodump dependency. Data can be stored in memory or on disk. Useful for fixtures reload.

Usage

With memory storage

import MongoDumper from 'mongo-collections-dumper';

let db = ...; // get database handler;

runSomeFixtures(); // prepare some data to dump

// save all collections in array
let fixturesData = MongoDumper.dump({
    storage: 'memory',
    db
});


// tests are great use case for mongo dumper
describe('Users', () => {
    beforeEach(function () {
        // rollback database to starting point before each test
        MongoDumper.restore({
            storage: 'memory',
            collectionsData: fixturesData,
            db
        });
    });
});

With file storage

import MongoDumper from 'mongo-collections-dumper';

let db = ...; // get database handler;

// fixtures for empty project are great use case for mongo dumper
if (databaseIsEmpty()) {

    // you can setup database from file added to project repo
    let {restored} = MongoDumper.restore({
        storage: 'file',
        file: 'fixtures.json',
        db
    });

    // if there's no file you can add fixtures and add them to repo
    if (!restored) {
        runSomeFixtures();

        MongoDumper.dump({
            storage: 'file',
            file: 'fixtures.json',
            db
        });        
    }
