loopback-example-connector (remote)

This is a very simple example of using the LoopBack remote connector, loopback-connector-remote.

Overview

The example has the following structure:

server: A LoopBack application that connects to a backend data source (just the in-memory data source here) and provides a CRUD API (both Node and REST) to interact with the data source.
client: A Node application that connects to the LoopBack server application using the remote connector. This acts as a very simple Node client SDK for LoopBack.
common/models: Model definitions shared between client and server applications. Using a shared model definition ensures that client and server expect the same model structures. This simple example defines onlyone model: Person, with a single property, name.
examples: Contains examples of using the Node SDK in client to connect to the server API.
create.js: A simple example script that creates a new Person record (instance).

How to run the examples

Clone the repo

$ git clone https://github.com/strongloop/loopback-example-connector.git
$ cd loopback-example-connector
$ git checkout remote

Starting the Server

Initially, you need to run npm install to install all the dependencies for both client and server. Then, start the server application.

$ cd client
$ npm install
$ cd ../server
$ npm install
$ node .

Basic CRUD Example

Now in another shell, run an example that uses the client “SDK.”

$ node examples/create.js
Created Person...
{ name: 'Fred', id: 1 }

Now open LoopBack Explorer at http://0.0.0.0:3001/explorer/. This provides a view into the server application REST API.

Go to http://0.0.0.0:3001/explorer/#!/People/find to expand the GET /People operation.Then click Try it!.

In Response Body, you will see the record that create.js created via the Node client SDK:

[
  {
    "name": "Fred",
    "id": 1
  }
]

Auth Example

This example demonstrates the following basic tasks (using the remote connector):

Registering a user
Logging in as a user
Defining a custom remote method
Securing access to custom methodsAfter running the server, you can run the examples/auth.js example in a separate shell.

$ node examples/auth.js
Got error (Authorization Required) when trying to call method without auth
Registered a user
Logged in as foo@bar.com
Set access token for all future requests. (MGd...JMA==)
Called a custom method (myMethod) as a logged in user
Logged out and unset the acces token for future invocations
Got error (Authorization Required) when trying to call method without auth
