Mongonaut

NodeJS module that totally Promises to import your JSON, CSV or TSV files to MongoDB.

Usage

let mongonaut = new Mongonaut({
  'host': 'localhost',
  'user': 'tomservo',
  'pwd': 'sol',
  'db': 'experiments',
  'collection': 'movies'
});

// pass a path to data file
mongonaut.import('./data.json')
  .then(function (response) {
    // code to fire on Promise resolve
  });

// change config to point to new collection
// then batch import multiple files.
mongonaut.set('collection', 'inventions');
  .import(['./data2.json', './some/other/data.json', './third.json'])
  .then(function (response) {
      // code to fire on Promise resolve
  });

// export "inventions" collection to a json file
mongonaut.export()
  .then(function (returnedCollections){
    // code to execute on Promise resolve
  });

Constructor(config)

config: object to apply configuration data. Available keys are host, user, pwd, db, collection which are used to authenticate with MongoDB, as well as options jsonArray - set as false if you want to use MongoDB's JSON format. (by default, Mongonaut will expect valid JSON files), and upsertFields if you need to specify fields

If authentication is not desired, then simply omit setting both user and pwd, or in the case of changing settings from using authentication to omitting authtentication, set both user and pwd to empty strings.

returns: Mongonaut instance.

.set([key, val] OR [config])

key: desired config key to set.

val: desired value of mongonaut.config[key]

config object to apply configuration data. Available keys are host, user, pwd, db, and collection which are used to authenticate with MongoDB.

If you intend to use MongoDB's default JSON formatting, then set jsonArray to false.

You can set upsertFields if you intend to specify specific fields for your query. Unless set by a user, Mongonaut ignores this setting.

Remember, both user and pwd must both either be set (for authentication), or set as the default/empty strings (for no authentication). Setting only one or the other will result in an error when you call .import().

note trying to set a key other than host, user, pwd, db or collection will result in an error.

returns: mongonaut

.import(targetfile OR [targetFiles])

targetFile: The file (.json, .csv, or .tsv) containing the data you wish to import to MongoDB.

[targetFiles] An array of file paths containing the data you wish to import.

returns: Promise

Resolving callback will be passed an array of objects (1 for each file originally imported) that contain the file that was imported, as well as the stdout and stderr values.

.export(collectionString OR [collectionStringArray])

collectionString: Name of a collection within the database set by the db property of a mongonaut instance

[collectionStringArray]: An array of strings that each match the name of a collection within the db property of the mongonaut instance.

Note that an argument for .export() is optional, and will default to the collection set within the instnace's configured collection property.

returns: Promise

Resolving callback will be passed an array of objects (1 for each collection originally exported) that contain the collection that was exported, as well as the stdout and stderr values.
