What is Guard? Guards make sure that the application user with the access permission can access that particular area in the application. It is mainly used to protect routes.
CanActivate - this guard helps decide whether a route can be activated or not.
CanActivateChild - this guard helps to decide whether children routes of a route can be activated or not.
CanDeactivate - this guard helps decide whether a route can be deactivated or not.
CanLoad - this guard helps decide whether a module can be loaded lazily or not
Guards can be implemented in different ways, but after all it really boils down to a function that returns either Observable<boolean>, Promise<boolean> or boolean. In addition, guards are registered using providers, so they can be injected by Angular when needed.
To register a guard we need to define a token and the guard function. Here’s what a super simple guard implementation could look like:
Mojito is an environment agnostic, MVC web application framework architected by Ric Allinson which supports agile development of web applications. ... Mojito is capable of running on both client(browser) and the server(Node.js) because both client and server side components are written in single language
Mojito provides seamless MVC framework to manage code base on server as well as on client side. The advantages of using Mojito are:
Mojito has two unique features to empower you on this area.
Runtime context : which is a predefined set of dimensions/variables with a finite number of possibilities/values that will define the state of the execution at any given time. Environment agnostic : the unique ability to run the same code in different runtimes. E.g.: browser, server, iOS UIWebView or any other phoneGap similar runtime.
Multi-Model: Documents, graphs and key-value pairs — model your data as you see fit for your application. Joins: Conveniently join what belongs together for flexible ad-hoc querying, less data redundancy. Transactions: Easy application development keeping your data consistent and safe. No hassle in your client.
ArangoDB is to use the arangoimp command-line tool. arangoimp allows you to import data records from a file into an existing database collection.
ArangoDB provides scalable, highly efficient queries when working with graph data.The database uses JSON as a default storage format, but internally it uses ArangoDB's VelocyPack - a fast and compact binary format for serialization and storage.ArangoDB can natively store a nested JSON object as a data entry inside a collection. Therefore, there is no need to disassemble the resulting JSON objects.
What is KeyStone.Js? KeystoneJS is a powerful Node.js content management system and web app framework built on express and mongoose. Keystone makes it easy to create sophisticated web sites and apps, and comes with a beautiful auto-generated Admin UI.
KeystoneJS is the easiest way to build database-driven websites, applications and APIs in Node.js.
Express.js and MongoDB
Auto-generated Admin UI
Keystone uses Mongoose, the leading ODM for node.js and MongoDB, and gives you a single place for your schema, validation rules and logic.
Keystone can configure Express for you, or you can take over and treat Keystone like any other Express middleware.
You can also easily integrate it into an existing Express app.
Sencha Touch has been merged with Ext JS, which provides developers with everything they need to build data-intensive web apps.
For individual developers and freelancers, Ionic, Onsen UI or Framework7 will be a better choice but for enterprises application, Sencha Touch leads the way.
Sencha Touch scores highly against its competitors by providing a native look and feel across all of the platforms it supports.
Jeet is a grid system built on top of Sass and Stylus. It consists of powerful mixins and functions you can use to create fast responsive layouts.
Unlike many other grids, Jeet provides a more flexible approach for producing layouts. Here are its main advantages:
It doesn’t add any additional markup. It isn’t limited to a specific column size (e.g. 12-column grid). You can use fractions (e.g. 1/4), decimals (e.g. 0.75), or even a combination of them (e.g. 1.5/4) for generating the desired layout. The grid is designed to work in all major browsers including IE9+. If you want to target previous versions of IE, take a look at the Boy boilerplate.
The grid comes in two flavors, one for Sass(SCSS) and another for Stylus. Depending on the preprocessor you want to use, there’s a different installation method.
This library includes a few built-in architectures like multilayer perceptrons, multilayer long-short term memory networks (LSTM), liquid state machines or Hopfield networks, and a trainer capable of training any given network, which includes built-in training tasks/tests like solving an XOR, completing a Distracted Sequence Recall task or an Embedded Reber Grammar test, so you can easily test and compare the performance of different architectures.
