node-mongoose-cli

mongoose-cli

A handy CLI for speeding up mongoose-related workflow. Generate model and migration files automatically, and seed data.

NPM use

npm install -g node-mongoose-cli

This will give you the mongoose command. Type that to get the help page.

1. Make your first model with:

mongoose-cli generate model [model name]

2. Set the Mongo URI (configurate)

mongoose-cli setUri 'mongodb://user:pass@localhost:27017/cli'

Now you can save to your DB, seed it, drop it, and probe it with one of the shells.

3. Use these commands

help: Provides details for a command

seed: Runs or Revert the seed

drop: Drops some or all of the collections

generate: Creates a model or migration or seed file

4. Easily connect to MongoDB and require models!

You can require the models individually, or just require them all like so:

const db = require('./db');
// db.ModelName.find().then(res=>{}); //example

Docs

Getting help

mongoose-cli help [command name]

Get details for a command.

Initializing project

mongoose-cli init

Generates files and directory structure (triggered automatically when a model is generated).

Setting MongoDB URI

mongoose-cli setUri <uri>

Tells mongoose where the MongoDB is. Give it a mongo connection string, e.g. mongodb://user:pass@localhost:27017/db. If you need to dynamically determine the URI (e.g. have it depend on an enviroment variable), then you should directly edit the db/connection-config.js file instead.

Creating models

mongoose-cli generate model <model name>

Example

# JavaScript data types 
mongoose-cli generate model user

generates this model file called User.js:

    ...
    
module.exports = mongoose.model('User', UserSchema);

Seeders

Create seed

mongoose-cli generate seed <model name>

Start seed for model

mongoose-cli seed run <name-model>

or all seeders

mongoose-cli seed run all

Revert seed for model

mongoose-cli seed undo <name-model>

or all seeders

mongoose-cli seed undo all

Migrations

mongoose-cli generate migration <model name>

MongoDB doesn't technically need migrations since the schema is in the application layer. However, if similar operations need to be done on many documents in a collection, a migration file is a convenient place to do that. These files are just scripts with the model required in them.

const mongoose = require('mongoose');
let User = require('../models/User.js');
 
 
// manipulate your data here
User.find({})
    .then(results => {
        // you migration actions
    
        console.log(results);
        mongoose.connection.close();
    });

Once generated and editted, they need to be run manually, e.g. node db/migrations/User-1447177237834.js.

Drop collections

mongoose-cli drop [model names]

Use this command to empty a collection or several. Drop all collections with no arguments.
