marpat

Marpat is lightweight object modeling tool that uses ES6 classes to model data. This project is a fork of Camo. Marpat is designed to be a storage agnostic document collection backend. By default Marpat can connect to nedb, mongodb. Additionally, Marpat provides a Client Registry and DocumentClient class. The client registry and DocumentClient class can be used to use a custom backend.

Install and Run

To use Marpat, you must first have installed Node >=8.0.x, then run the following commands:

npm install marpat --save

And at least ONE of the following:

npm install nedb --save

OR

npm install mongodb --save

Quick Start

Marpat was built with ease-of-use and ES6 in mind, so you might notice it has more of an OOP feel to it than many existing libraries and ODMs. Don't worry, focusing on object-oriented design doesn't mean we forgot about functional techniques or asynchronous programming. Promises are built-in to the API. Just about every call you make interacting with the database (find, save, delete, etc) will return a Promise.

Connect to the Database

Before using any document methods, you must first connect to your underlying database. All supported databases have their own unique URI string used for connecting. The URI string usually describes the network location or file location of the database. However, some databases support more than just network or file locations. NeDB, for example, supports storing data in-memory, which can be specified to Marpat via nedb://memory. See below for details:

MongoDB:
- Format: mongodb://[username:password@]host[:port][/db-name]
- Example: const uri = 'mongodb://Ben:abc123@localhost:27017/animals';
NeDB:
- Format: nedb://[directory-path] OR nedb://memory
- Example: const uri = 'nedb://data';

So to connect to an NeDB database, use the following:

const { connect } = require('marpat')

const database;
const uri = 'nedb://data';
connect(uri).then(function(db) {
    database = db;
});

Creating A Model

All models must inherit from the Document class, which handles much of the interface to your backend NoSQL database.

const { Document } = require('marpat');

class Ghostbuster extends Document {
    constructor() {
        super();

        this.name = String;
        this.age = {
            type: Number,
            min: 0
        };
        this.employees = [String];
        this.dateFounded = {
            type: Date,
            default: Date.now
        };
        this.
    }

    static collectionName() {
        return 'companies';
    }
}

Notice how the schema is declared right in the constructor as member variables. All public member variables (variables that don't start with an underscore [_]) are added to the schema. The name of the collection can be set by overriding the static collectionName() method, which should return the desired collection name as a string. If one isn't given, then Marpat uses the name of the class and naively appends an 's' to the end to make it plural. Schemas can also be defined using the this.schema() method. For example, in the constructor() method you could use:

this.schema({
    name: String,
    valuation: {
        type: Number,
        default: 10000000000,
        min: 0
    },
    employees: [String],
    dateFounded: {
        type: Date,
        default: Date.now
    }
});

Currently supported variable types are:

String
Number
Boolean
Buffer
Date
Object
Array
EmbeddedDocument
Document Reference
Joi Schema

Arrays can either be declared as either un-typed (using Array or []), or typed (using the [TYPE] syntax, like [String]). Typed arrays are enforced by Marpat on .save() and an Error will be thrown if a value of the wrong type is saved in the array. Arrays of references are also supported.

To declare a member variable in the schema, either directly assign it one of the types listed above, or assign it an object with options, like this:

this.primeNumber = {
    type: Number,
    default: 2,
    validate: (value) => typeof value === "number"
    min: 0,
    max: 25,
    choices: [2, 3, 5, 7, 11, 13, 17, 19, 23],
    unique: true
};

The default option supports both values and no-argument functions (like Date.now). Currently the supported options are:

type: The value's type (required)
default: The value to be assigned if none is provided (optional)
min: The minimum value a Number can be (optional)
max: The maximum value a Number can be (optional)
choices: A list of possible values (optional)
match: A regex string that should match the value (optional)
validate: A 1-argument function that returns false if the value is invalid (optional)
private: A boolean indicating the member value should be removed by the toJSON method (optional)
unique: A boolean value indicating if a 'unique' index should be set (optional)
required: A boolean value indicating if a key value is required (optional)

To reference another document, just use its class name as the type.

class Dog extends Document {
    constructor() {
        super();

        this.name = String;
        this.breed = String;
    }
}

class Person extends Document {
    constructor() {
        super();

        this.pet = Dog;
        this.name = String;
        this.age = String;
    }

    static collectionName() {
        return 'people';
    }
}

Schema Declaration

Embedded Documents

Embedded documents can also be used within Documents. You must declare them separately from the main Document that it is being used in. EmbeddedDocuments are good for when you need an Object, but also need enforced schemas, validation, defaults, hooks, and member functions. All of the options (type, default, min, etc) mentioned above work on EmbeddedDocuments as well.

var { Document } = require('Marpat');
var { EmbeddedDocument } = require('Marpat');

class Money extends EmbeddedDocument {
    constructor() {
        super();

        this.value = {
            type: Number,
            choices: [1, 5, 10, 20, 50, 100]
        };

        this.currency = {
            type: String,
            default: 'usd'
        };
    }
}

class Wallet extends Document {
    constructor() {
        super();
        this.contents = [Money];
    }
}

const wallet = Wallet.create();
wallet.contents.push(Money.create());
wallet.contents[0].value = 5;
wallet.contents.push(Money.create());
wallet.contents[1].value = 100;

wallet.save().then(function() {
    console.log('Both Wallet and Money objects were saved!');
});

Creating and Saving

To create a new instance of our document, we need to use the .create() method, which handles all of the construction for us.

const lassie = Dog.create({
    name: 'Lassie',
    breed: 'Collie'
});

lassie.save().then(function(l) {
    console.log(l._id);
});

Once a document is saved, it will automatically be assigned a unique identifier by the backend database. This ID can be accessed by the ._id property.

If you specified a default value (or function) for a schema variable, that value will be assigned on creation of the object.

An alternative to .save() is .findOneAndUpdate(query, update, options). This static method will find and update (or insert) a document in one atomic operation (atomicity is guaranteed in MongoDB only). Using the {upsert: true} option will return a new document if one is not found with the given query.

Loading

Both the find and delete methods following closely (but not always exactly) to the MongoDB API, so it should feel fairly familiar.

If querying an object by id, you must use _id and not id.

To retrieve an object, you have a few methods available to you.

.findOne(query, options) (static method)
.find(query, options) (static method)

The .findOne() method will return the first document found, even if multiple documents match the query. .find() will return all documents matching the query. Each should be called as static methods on the document type you want to load.

Dog.findOne({ name: 'Lassie' }).then(function(l) {
    console.log('Got Lassie!');
    console.log('Her unique ID is', l._id);
});

.findOne() currently accepts the following option:

populate: Boolean value to load all or no references. Pass an array of field names to only populate the specified references
- Person.findOne({name: 'Billy'}, {populate: true}) populates all references in Person object
- Person.findOne({name: 'Billy'}, {populate: ['address', 'spouse']}) populates only 'address' and 'spouse' in Person object
- select: removes all properties from the returning data except those that match an array of values, or _id and _schema
- Person.findOne({}, {select: ['name']}) returns data with properties _id, _schema, and name.

.find() currently accepts the following options:

populate: Boolean value to load all or no references. Pass an array of field names to only populate the specified references
- Person.find({lastName: 'Smith'}, {populate: true}) populates all references in Person object
- Person.find({lastName: 'Smith'}, {populate: ['address', 'spouse']}) populates only 'address' and 'spouse' in Person object
sort: Sort the documents by the given field(s)
- Person.find({}, {sort: '-age'}) sorts by age in descending order
- Person.find({}, {sort: ['age', 'name']}) sorts by ascending age and then name, alphabetically
limit: Limits the number of documents returned
- Person.find({}, {limit: 5}) returns a maximum of 5 Person objects
skip: Skips the given number of documents and returns the rest
- Person.find({}, {skip: 5}) skips the first 5 Person objects and returns all others
select: removes all properties from the returning data except those that match an array of values, or _id and _schema
- Person.find({}, {select: ['name']}) returns data with properties _id, _schema, and name.

.findOneAndUpdate() currently accepts the following options:

populate: Boolean value to load all or no references.
- Person.findOneAndUpdate({name: 'Ben'},{name: 'Ben Danger'},{lastName: 'Smith'}, {populate: true}) populates all references in Person object
select: removes all properties from the returning data except those that match an array of values, or _id and _schema
- Person.findOneAndUpdate({name: 'Ben'},{name: 'Ben Danger'}, {select: ['name']}) returns data with properties _id, _schema, and name.

Deleting

To remove documents from the database, use one of the following:

.delete()
.deleteOne(query, options) (static method)
.deleteMany(query, options) (static method)
.findOneAndDelete(query, options) (static method)

The .delete() method should only be used on an instantiated document with a valid id. The other three methods should be used on the class of the document(s) you want to delete.

Dog.deleteMany({ breed: 'Collie' }).then(function(numDeleted) {
    console.log('Deleted', numDeleted, 'Collies from the database.');
});

Counting

To get the number of matching documents for a query without actually retrieving all of the data, use the .count() method.

Dog.count({ breed: 'Collie' }).then(function(count) {
    console.log('Found', count, 'Collies.');
});

Hooks

Marpat provides hooks for you to execute code before and after critical parts of your database interactions. For each hook you use, you may return a value (which, as of now, will be discarded) or a Promise for executing asynchronous code. Using Promises throughout Marpat allows us to not have to provide separate async and sync hooks, thus making your code simpler and easier to understand.

Hooks can be used not only on Document objects, but EmbeddedDocument objects as well. The embedded object's hooks will be called when it's parent Document is saved/validated/deleted (depending on the hook you provide).

In order to create a hook, you must override a class method. The hooks currently provided, and their corresponding methods, are:

pre-init: preInit(data)
pre-validate: preValidate()
post-validate: postValidate()
pre-save: preSave()
post-save: postSave()
pre-delete: preDelete()
post-delete: postDelete()
post-find: postFind()

Here is an example of using a hook (pre-delete, in this case):

class Company extends Document {
    constructor() {
        super();

        this.employees = [Person];
    }

    static collectionName() {
        return 'companies';
    }

    preDelete() {
        var deletes = [];
        this.employees.forEach(function(e) {
            var p = new Promise(function(resolve, reject) {
                resolve(e.delete());
            });

            deletes.push(p);
        });

        return Promise.all(deletes);
    }
}

The code above shows a pre-delete hook that deletes all the employees of the company before it itself is deleted. As you can see, this is much more convenient than needing to always remember to delete referenced employees in the application code.

Note: The .preDelete() and .postDelete() hooks are only called when calling .delete() on a Document instance. Calling .deleteOne() or .deleteMany() will not trigger the hook methods.

Custom Database Driver

Marpat provides two default database driver (NeDbClient and MongoDbClient). If you need to write you own database driver you can register it with the ClientRegistry service.

var { connect, ClientRegistry, DatabaseClient } = require('Marpat');

class MyClient extends DatabaseClient {
    static canHandle(url) {
        return url.indexOf('foo://') === 0;
    }
}

ClientRegistry.add(MyClient);

connect('foo://bar').then(function(db) { });

Misc.

Marpat.Client(): Retrieves the marpat database client
Marpat.Client().driver(): Retrieves the underlying database driver (MongoClient or a map of NeDB collections)
Document.toJSON(): Serializes the given document to just the data, which includes nested and referenced data

Transpiler Support

While many transpilers won't have any problem with Marpat, some need extra resources/plugins to work correctly:

Babel
- babel-preset-marpat: Babel preset for all es2015 plugins supported by marpat
TypeScript
- DefinitelyTyped/marpat: marpat declaration file (h/t lucasmciruzzi)
- IndefinitivelyTyped/marpat: Typings support for marpat (h/t WorldMaker)
