Mongoose API for Scala.js

mongoose - Mongoose MongoDB ODM.

Description

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.

NOTE: This is a work-in-progress binding.

Build Dependencies

• SBT v1.2.x

Build/publish the SDK locally

 $ sbt clean publish-local

Running the tests

Before running the tests the first time, you must ensure the npm packages are installed:

$ npm install

Then you can run the tests:

$ sbt test

import io.scalajs.JSON
import io.scalajs.nodejs._
import io.scalajs.npm.mongodb.doc
import io.scalajs.npm.mongoose._

// define the schema

// register the model
val Contacts = Mongoose.model("Contact", contactSchema)

// create and populate an instance of the model
val newContact = Contacts()
newContact.name = "John Doe"
newContact.age = 21
newContact.bio = "Lover of life"
newContact.date = js.Date.now()

for {
    // connect to the database
    _ <- Mongoose.connectAsync("mongodb://localhost:27017/test").future

    // delete the contact
    deleted <- oneContactWhere.remove().toFuture
    _ = println(s"deleted contact: ${JSON.stringify(deleted)}")
} {
    println("Done.")
}

Artifacts and Resolvers

To add the Mongoose binding to your project, add the following to your build.sbt:

libraryDependencies += "io.scalajs.npm" %%% "mongoose" % "0.5.0"

Optionally, you may add the Sonatype Repository resolver:

resolvers += Resolver.sonatypeRepo("releases")
