This is a REPL (read-eval-print-loop) for mongoose.

Node 7.5

This project relies on async await to provide a good experience, please ensure that you have a compatible version of NodeJs.

To add to project:

npm install --save-dev @hubba/hubba-repl

To use:

const repl = require('@hubba/hubba-repl');

// Initialize the mongoose connection
mongoose.connect( config.mongo.uri, config.mongo.options );

// initialize the repl
repl({
    dirname: path.join(__dirname, '../server/'),
    mongoose
});

The repl can be initialized with the path of the directory to walk through to find models.

The default model files that will be loaded are: modelFileRegex The regular expression deciding which files are to be loaded.

Once the files are loaded by node, they will be checked if they export a specific interface.

The model files must export mongoose models as their root export. EX:

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

Once integrated the repl provides some a command:

List all the models that have been loaded.

    node repl.js
    > .models
    [ 
    'UserMetadata',
    'User',
    'SchemaVersion' ]

This will list all of your models that have been loaded and are available in the global scope.

This will also list all the paths of a model if a model is specified.

    node repl.js
    > .models User
    name : String - 
    status : String - draft,published
    updatedAt : Date  
    createdAt : Date  
    deleted : Boolean  
    deletedAt : Date 

The first element in the list is the model property. The second property after the colon is the type. If there is a dash then the following properties are available enum values.

To find a model -- for the sake of example lets use User -- you may use a variety of commands:

    node repl.js
    > User.find({})
    [{ _id: 597ba6811a651e6be35fe859,
    n: 'Blahblah User'}]
    > User.findById('597ba6811a651e6be35fe859')
    { _id: 597ba6811a651e6be35fe859,
    n: 'Blahblah User'} 
    > User.findOne({_id: ObjectId('597ba6811a651e6be35fe859')})
    { _id: 597ba6811a651e6be35fe859,
    n: 'Blahblah User'} 

ObjectId Method will automatically create a mongoose object id, the idea behind this is for those people who want to use a syntax similiar to the mongodb REPL have the ability.

To create a model you can use User.create. The model will run all pre and post hooks as well as any validations.

If your model is initialized with the isWritable attribute false, then create will throw an exception when called.

    node repl.js
    > User.create({n: 'Test User'})
    { _id: 597ba6811a651e6be35fe859,
    n: 'Test User'}

If you would like to do a multi document update then you can use the User.setWhere(query, values) command.
