Learn Gulp, Mongodb and Particle

MongoDB has a quite powerful aggregation framework that allows you to write data processing pipelines. Documents in the MongoDB collection go through a series of stages or a pipeline that transforms them into an aggregated result. In this short video series, you will learn how to write aggregations in MongoDB.

MongoDB Aggregation Framework

In this series we will take a look at Gulp. Gulp is a task runner. It is the commander of our army of helper robots that take critical, yet totally mundane, tasks and perform them hundreds of times per day so we don't have to. When we sit down to work, we want to enter a single command, and then spend the rest of our day writing code, testing, and basically not thinking about how it is all glued together in the background.

Automation is critical to any project of significant size. We will start with the Eggly Bookmarks application, and develop proper build automation that will include **production ready** tools that you can start using in your applications today!

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Angular Automation with Gulp

In this lesson, we are going to learn how to create a config file to store common values so that we can reuse them multiple times in our `gulpfile.js`. As our `gulpfile.js` grows in complexity, we may find that we are introducing complex and multiple file path references. By creating a `gulp.config.js` file, we can simplify these references and make it easier to refactor and extend in the future. 

Angular Automation: Gulp Config

In this lesson, we are going to learn how to use `gulp.watch` to detect local file changes and execute additional Gulp tasks. To illustrate this concept, we are also going to hook up `gulp-jshint` to automation lint our JavaScript as we make changes to our code.

Angular Automation: Gulp Watch

Angular projects require automation. Period.

Angular Automation: Introduction to Gulp

In this lesson, we are going to learn how to copy assets from one place to another using Gulp. This is important as you start to prepare your source files to be deployed into production. We will learn how to implement `gulp.src`, `gulp.pipe` and `gulp.dest` as well as the **del** plugin as we copy our files from the source directory into a build directory.

In this lesson, we are going to learn how to use the `gulp-inject` plugin to sanely and efficiently manage our file references with our HTML. Manually declaring JavaScript references will quickly get out of hand as your application grows in size and complexity. The `gulp-inject` plugin solves this problem by taking a stream of files, converting them into string references and then injecting those references into your HTML via annotations.

In this lesson, we are going to learn how to automatically serve our project via an HTTP server using `gulp-serve`. Being able to serve our project from an HTTP server allows us to bypass a myriad of development issues such as loading remote source files.

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

Mongoose allows you to easily select resources by ID from your MongoDB. This is an important aspect to creating an API.

In this lesson, we will learn how tasks work in Gulp. We will talk about how to define a task and what each parameter in the definition does. We will see how task dependencies work and talk about how to handle asynchronous issues using `run-sequence`.

Angular Automation: Gulp Tasks

In this lesson, we learn how to get up and running with Gulp by initializing our project with ```npm init``` and then installing the Gulp CLI globally and then installing it locally to our project. We finish the lesson off by creating our first Gulp file and running our first Gulp task.

Learn how to import data into your MongoDB and then use Express to serve a simple Node.js API.

Gulp is a toolkit for automating painful or time-consuming tasks in your development workflow, so you can stop messing around and build something.

Building upon the `watch` task that we begin this lesson with, we’ll look at how to create a local development server using the `app` directory as the web root. By using Browsersync to achieve this, we can also instruct all connected browsers to automatically reload each time our bundle is re-generated. Browsersync has a public `.stream()` method that is designed exactly for this purpose.

Babel has support for the latest version of JavaScript through syntax transformers. These plugins allow you to use new syntax, right now without waiting for browser support.

What is already a nice workflow using Gulp, Browserify, Watchify & Browsersync to enable auto rebuilds & live browser reloading can be further improved by adding Babelify. A simple wrapper around the popular transpiler Babel, Babelify can ‘transform’ source files as they pass through our stream to enable certain Javascript features not yet available in the Browser or Node. We end the lesson by looking at how to generate & extract sourcemaps using `exorcist`.

Browserify lets you require('modules') in the browser by bundling up all of your dependencies.

Let's look at the basics of setting up Gulp and Browserify. Creating a Gulp task from scratch, we'll cover how to utilise the Browserify API to generate a single `bundle.js` file, catch and log any errors that occur in the compilation process, transform the stream into a format that can be consumed by `gulp.dest` and finish by writing the bundle to a `dist` directory.

Gulp and Browserify - Initial Setup

A brief introduction to using GulpJS in your JavaScript application and creating your first Gulp task.

Installing and Writing a Default Task with Gulp

Beginning with a single Gulp task capable of generating a one-time Browserify bundle, we enable file-watching and incremental rebuilds by incorporating Watchify. We add a second task `watch` & refactor our initial code to enable the bulk of it to be re-used. We’ll look at exactly how to ‘wire’ these tools together and how the relationship between Watchify & Browserify can manifest into a seriously efficient workflow.

Gulp and Browserify - Hooking up Watchify

We will look at bundling your JavaScript files using Gulp, Gulp-Concat, and Gulp-Uglify

Before powering up the Particle Photon we are going to look at what each of the components are on the board.

Particle Photon Component Overview

Aggregation in MongoDB is really powerful and allows you to create solid pipelines to extract and transform data. This is an introductory video that aims to demonstrate the basics of aggregation — we will see how to create some basic pipeline to extract data using `$match` and manipulate the output using `$project` stages.

The aggregation stages/operators covered in this video are:

* [`$match`](https://docs.mongodb.com/manual/reference/operator/aggregation/match/index.html)
* [`$project`](https://docs.mongodb.com/manual/reference/operator/aggregation/project/index.html)
* [`$concat`](https://docs.mongodb.com/manual/reference/operator/aggregation/concat/)

You can see the list of all the [available operators in the MongoDB docs](https://docs.mongodb.com/manual/reference/operator/aggregation/)


Find and Manipulate Data using Aggregation in MongoDB

In our last lesson, we learnt the basics of MongoDB aggregation and saw how we can [find and manipulate data](https://egghead.io/lessons/mongodb-find-and-manipulate-data-using-aggregation-in-mongodb). In this continuation, we will see how we can sort, skip and limit records during our aggregation stages.

The aggregation stages/operators covered in this video are:

* [`$sort`](https://docs.mongodb.com/manual/reference/operator/aggregation/sort/index.html)
* [`$skip`](https://docs.mongodb.com/manual/reference/operator/aggregation/skip/index.html)
* [`$limit`](https://docs.mongodb.com/manual/reference/operator/aggregation/limit/index.html)
