mongo-fixeeds

Simple fixtures and seeds loading tool for MongoDB inspired by pow-mongodb-fixtures

Installation

$ npm install mongo-fixeeds

How to use

Fixtures or seeds can be placed into separate files or one in different hierarchy of directories, there are 2 modes using this tool, normal mode and custom mode, you can specify the operation for each fixtures and seeds in custom mode.

The data files must export objects with the same key name as the MongoDB collection name, and the value must be an array or object contains the documents.

suppose we have some data to load as follows:

// user-seeds.js
const users = [
  {
    _id: new ObjectId('5a714a8e7a50fd6a8ca792c0'),
    name: 'Alice',
    sex: 0,
    createdAt: new Date(),
    updatedAt: new Date()
  }
];

const accounts = [
  {
    _id: new ObjectId('5a79f976cd1f373fd5a75980'),
    user: new Objectid('5a714a8e7a50fd6a8ca792c0'),
    name: '[e-mail]',
    createdAt: new Date(),
    updatedAt: new Date()
  }
];

Normal mode

All documents will be loaded by default in MongoDB using upsert behaviour, _id must be specified for each document.

exports.users = users;
exports.accounts = accounts;

Custom mode

You can specify operation or behaviour for each document in custom mode, exports data key must be an object, the documents must be set to data property as its value.

Insert operation

// users will be inserted to MongoDB except that
// those can be found by _id in MongoDB.
// if _id not specified for user document, next time running will load a new user to MongoDB
exports.users = { 
  data: users, 
  operation: 'insert',
  except: e => ({_id: e._id }) // can be omitted here, because it's the default behaviour
};

// accounts will be inserted to MongoDB except that
// those can be found by name in MongoDB.
exports.accounts = {
  data: accounts,
  operation: 'insert',
  except: e => ({ name: e.name })
};

Update operation

// accounts will be upserted to MongoDB except that
// those can be found by name in MongoDB
// excludes properties will not be modified at next running
// excludes will only work on operation 'update'
exports.accounts = {
  data: accounts,
  operation: 'update',
  excludes: ['createdAt'],
  except: e => ({ name: e.name })
};

Ignore documents

Sometimes data will only be exported to other documents to use, you can use ignore to specify the documents will not be loaded to MongoDB.

module.exports = {
  data: accountInfos,
  ignore: true
};

APIs

Loader(mongoUrl, options)

Return a new Loader instance connect to a specified MongoDB and load strategy.

• mongoUrl, complete url with specified database name
• options
  • excludes, properties will be ignored when data running repeatedly, only valid on operation update, all proerties will be updated every load if not set
  • operations, only insert and update supported, default value is update if not set
  • files, the files will be loaded to MongoDB, all files on that directory will be loaded if not set

const mongoFixeeds = require('mongo-fixeeds');
const options = {
  excludes: ['createdAt'],
  operation: 'update',
  files: ['seeds.js']
};
const mongoUrl = 'mongodb://localhost:27017/mongo-test';
const seedsLoder = new mongoFixeeds.Loader(mongoUrl, options);

load(dataFilesPath)

Load all specified data to MongoDB under the specified directory recursively.

const mongoFixeeds = require('mongo-fixeeds');
const seedsPath = path.join(__dirname, '../data/seeds');
const options = {
  excludes: ['createdAt'],
  operation: 'update',
  files: ['seeds.js']
};
const mongoUrl = 'mongodb://localhost:27017/mongo-test';
const seedsLoder = new mongoFixeeds.Loader(mongoUrl, options);
seedsLoder.load(seedsPath)
  .then(({ mc, uc, ic }) => {
    console.log('modifiedCount:', mc);
    console.log('upsertedCount:', uc);
    console.log('insertedCount:', ic);
  });

clearAll()

Clear all collections data in MongoDB.

seedsLoder.clearAll();

clearAllAndLoad(dataFilesPath)

Clear all collections data and then load all data into MongoDB.

seedsLoder.clearAllAndLoad(seedsPath)
  .then(({ mc, uc, ic }) => {
    console.log('modifiedCount:', mc);
    console.log('upsertedCount:', uc);
    console.log('insertedCount:', ic);
  });
