    Introduction

    This package, Mongoosejs-cli, is a package for nodejs to help generate and run migrations and seeders for mongoosejs with ease.

    Note that this is an unofficial CLI package for mongoosejs.

    Prerequisites🔨

    • node >=11.0.0
    • yarn >= 1.16.0 || npm >= 6.0.0
    • mongoosejs >= 5.5.12

    Installation🛠

    Globally

    There are two ways to of installing and using this package:

    yarn global add mongoosejs-cli
    • Usage
      • mongoose

    Locally

    yarn add mongoosejs-cli
    • Usage
      • npx mongoosejs-cli

    Note 📓

    It is recommended to install the package in your project(local). We'll be using the local approach in the following examples.

    Usage

    Make sure you have mongoose already installed in your project before proceeding.

    To display list of options that the command has, do the following

    npx mongoosejs-cli

    You'll see the following on your terminal:

    Options:
      --help     Show help                                                                                    [boolean]
      --version  Show version number                                                                          [boolean]

    To initialize the project

    We recommend that after viewing the lis of commands, first thing to do, is to generate the required files and directories needed to get started. It can achieved by entering the following command.

    npx mongoosejs-cli init

    This will generate the following:

     config/
      config.json
     models/
      index.js
     migrations/
     seeders/
    • config/ => the directory containing all your configuration files
      • config.json => the default configuration files that contains the database connection strings based on the environment(NODE_ENV). You can add extra environments as well.
    • models/ => the directory that contains all your mongoose models you generated through the package
      • index.js => this file does the database connection and imports all your models
    • migrations/ => directory containing all your migration files
    • seeders/ => directory containing all your seed files

    Options

    Changing path

    By default, mongoosejs-cli generates the migrations, seeders and models directories and files in the root directory of your project. To change this behaviour, create a new file called .mongooserc manually or use the the following command:

    touch .mongooserc

    and paste the following code inside the new created file

    const path = require('path');
    
    module.exports = {
      'config': path.resolve('config', 'database.json'),
      'models-path': path.resolve('db', 'models'),
      'seeders-path': path.resolve('db', 'seeders'),
      'migrations-path': path.resolve('db', 'migrations')
    }

    Now the CLI will look for its

    • configuration settings inside ./config/database.json
    • models files inside ./db/models/
    • migration files inside ./db/migrations/
    • seed files inside ./db/seeders/

    Configuration file

    By default the CLI will try to use the file config/config.js. You can modify that path either via the --config flag or via the option mentioned earlier. Here is how a configuration file might look like (this is the one that npx mongoosejs-cli init generates):

    {
      "development": {
        "database": {
          "url": "mongodb://localhost/mongoose_dev",
          "options": {
            "useNewUrlParser": true
          }
        }
      },
      "test": {
        "database": {
          "url": "mongodb://localhost/mongoose_test",
          "options": {
            "useNewUrlParser": true
          }
        }
      },
      "production": {
        "database": {
          "protocol": "mongodb",
          "username": "root",
          "password": "password",
          "name": "database_production",
          "host": "localhost",
          "port": "",
          "options": {
            "useNewUrlParser": true
          }
        }
      }
    }

    Configuration for connecting over SRV

    In case you are using MongoDB Atlas or any other services that supports srv, kindly remove database name known as "name" from the database main object and assign its value to a new string called "dbName" in the options object, such as the following.

    {
    
      "production": {
        "database": {
          "protocol": "mongodb+srv",
          "username": "root",
          "password": "password",
          "host": "subdomain.mongodb.com",
          "port": "",
          "options": {
            "useNewUrlParser": true,
            "dbName": "database_production",
          }
        }
      }
    }

    In case you want to use a url string instead, do the following

    {
    
      "production": {
        "database": {
          "url": "mongodb+srv://root:password@subdomain.mongodb.com/database_production",
          "options": {
            "useNewUrlParser": true,
            "dbName": "database_production",
          }
        }
      }
    }

    FAQ

    The Mongoosejs Command Line Interface (CLI) Frequently Asked Question

    Initialize mongoose to create necessary files in the project

    $ npx mongoosejs-cli init
    

    How can I generate a model?

    Specify model name with --name argument. List of table fields can be passed with --attributes option. Note that the datatypes are using Mongoose SchemaTypes when defining them using the CLI.

    $ npx mongoosejs-cli model:create --name User --attributes name:String,state:Boolean,birth:Date,card:Number
    

    You can create your own custom datatypes as plugins after the model file has been generated for you. Refer to Mongoose Plugins, on how to do so.

    How can I create a migration?

    Specify migration name with --name argument

    $ npx mongoosejs-cli migration:create --name <migration_name>
    

    How do call/use a model defined?

    You can call/use a model(eg: Player) by doing the following:

    const models = require('path_to_models_folder');
    
    const players = await models.Player.find({});
    
    console.log(players) // will print players collection

    What is the command to execute all migrations?

    $ npx mongoosejs-cli db:migrate
    

    How can I make a migrations rollback?

    $ npx mongoosejs-cli db:migrate:undo:all
    

    How can I create a seeder?

    Specify seeder name with --name argument

    $ npx mongoosejs-cli seed:create --name <seeder_name>
    

    How can I run the seeders?

    $ npx mongoosejs-cli db:seed:all
    

    How can I make the seeders rollback?

    $ npx mongoosejs-cli db:seed:undo:all
    

    Do you have an example of how the structure of the project look like?

    Yes. Please check the examples folder in this project. Screenshots can also be found here

    Credits👌

    This package would not have been made possible if not for the following:

    • Mongoosejs Contributors and maintainers for the awesome ORM specially for mongodb on nodejs
    • Sequelize for their CLI, which Mongoosejs-cli structure was heavily based on.
    • Kefranabg, for his readme-md-generator package which generated the skeleton for this readme file.
    • Nodejs, Yarnpkg, NPM etc...
