loopback-full-stack-tenancy

example showing how to implement full-stack stateless multi-tenancy with loopback

Installation & Usage

install server dependencies:

npm install

install client dependencies:

cd client
npm install
node_modules\.bin\gulp

run server:

node .

run client:

open "client/index.html"

Sample-Usecase

• one automatically created user

  username: test@test.com
password: test

• one data-source per family

• one person in each family

• one pet related to each person

• three automatically created memory data-sources

• MS-SQL data-sources that will be dynamically added during runtime

• check server/sql-server-config.js for the connection settings

Multi-Tenancy Sample Features

• separate data-sources hosted via unified REST models
• user-login based access control for data-sources
• fully flexible querying of data-sources
• no state about the active data-source on the server
• the target data-source is determined independently for each request

Notes

If you want to compile the html client bundle yourself you also need to patch the loopback-connector-remote in the client node_modules, with the following code. (There is also a pull-request in loopback-connector-remote to add this change, but it has still to be accepted)

This goes at the end of the file: loopback-full-stack-tenancy\client\node_modules\loopback-connector-remote\lib\relations.js

function defineRelationProperty(modelClass, def) {
    Object.defineProperty(modelClass.prototype, def.name, {
        get: function() {
        var that = this;
        var scope = function() {
            var cached = that.__cachedRelations[def.name];
            
            if (arguments.length == 0)
                return cached;
            
            return that['__get__' + def.name].apply(that, arguments);
        };
        scope.count = function() {
            return that['__count__' + def.name].apply(that, arguments);
        };
        scope.create = function() {
            return that['__create__' + def.name].apply(that, arguments);
        };
        scope.deleteById = scope.destroyById = function() {
            return that['__destroyById__' + def.name].apply(that, arguments);
        };
        scope.exists = function() {
            return that['__exists__' + def.name].apply(that, arguments);
        };
        scope.findById = function() {
            return that['__findById__' + def.name].apply(that, arguments);
        };
        return scope;
        }
    });
