mongodb-io v0.2.5

mongodb-io

export & import mongodb documents, base on mongodump and mongorestore.

Support

only for linux x64 and OS X x64.

Usage

import DBIO from 'mongodb-io';

config

The second argument in DBIO.export or DBIO.import, params and default value seems like:

{
  host: 127.0.0.1,
  port: 27017,
  user,
  password,
  out: 'dump', // export filename
  drop: false, // Before restoring the collections from the dumped backup, drops the collections from the target database.
  filePath: '' // path to read `tar.gz` file for mongorestore.
}

export

var filePath = await DBIO.export({config, dbs}); // this is a `tar.gz` file

if dbs is not a array, will export all dbs. dbs is seems like:

['dbName1', {name: 'dbName2', collections}, ...]

the array of database names, or database settings you want to export.

collections is seems like:

['collectionName1', {name: 'collectionName2', query: '{_id: 111}'}, ...]

the array of collection names, or collection settings you want to export.

import

await DBIO.import({config, dbs});

In each item of dbs or collections you could set drop, like that item in config.

errors

Error: {name: 'DBIO_XXX_ERR', message: 'where error happend'}
