DEEP Dependency Injection Library (deep-di)

DEEP Framework is a serverless web framework, core component of the Platform-as-a-Service that abstracts web apps and web services from specific cloud providers. This framework enables developers build cloud-native applications or platforms using microservices architecture in a completely serverless approach.

At this moment only Amazon Web Services is supported. Developers are encouraged to add support for Microsoft Azure, Google Cloud Platform, and so on.

Getting Started

DEEP Framework can be used as a module in front-end or back-end. To learn more, scroll down to What is DEEP Framework?

To see the power of DEEP Framework, execute the following 4 simple steps in command line:

1. Install DEEP CLI, also known as deepify:

npm install deepify -g

deepify is a collection of tools that empower developers and devops engineers to automate the management of web apps built on top of DEEP ecosystem.

1. Using deepify, dump locally the helloworld example:

deepify helloworld ~/deep-hello-world

deepify will clone the repository from GitHub and pull all the dependencies in one place.

1. Using deepify, run locally the helloworld example:

deepify server ~/deep-hello-world -o

deepify launches a web server that can be used for local development, without making calls to web services from cloud providers like AWS.

1. Using deepify, deploy to AWS the helloworld example:

deepify deploy ~/deep-hello-world

deepify provisions the infrastructure and deploys the web app, empowering developers and devops engineers to automate the process.

To learn more about helloworld example, or other web apps that run in production, scroll down to Who is using DEEP Framework?

Additional Notes

Note 1: To use DEEP Framework globally, just run in command line:

npm install deep-framework -g

Note 2: Alternatively, to use DEEP Framework as dependency, include it in package.json file. For example:

{
  "name": "say-hello-world",
  "version": "0.0.1",
  "description": "AWS Lambda that says hello to the world",
  "dependencies": {
    "deep-framework": "1.0.*",
    ...
  },
  ...
}

Note 3: Also, when needed, consider specifying only some libraries instead of entire framework. For example:

{
  "name": "say-hello-world",
  "version": "0.0.1",
  "description": "AWS Lambda that says hello to the world",
  "dependencies": {
    "deep-db": "1.0.*",
    "deep-event": "1.0.*",
    "deep-resource": "1.0.*",
    ...
  },
  ...
}

What is DEEP Framework?

DEEP Framework is a nodejs package that is published on npmjs: https://www.npmjs.com/package/deep-framework.

If you are new to node and npm, check out how to install nodejs tutorial.

DEEP Framework is a nodejs package. In fact it's a collection of nodejs packages, also known as DEEP Abstracted Libraries. Here below is the complete list:

DEEP Abstracted Library	Api Docs	Abstracted Web Service(s)
deep-asset	Assets Management Library	Amazon S3
deep-cache	Cache Management Library	Amazon ElastiCache
deep-core	Core Management Library	-
deep-db	Database Management Library	Amazon DynamoDB, Amazon SQS
deep-di	Dependency Injection Management Library	-
deep-event	Events Management Library	Amazon Kinesis
deep-fs	File System Management Library	Amazon S3
deep-kernel	Kernel Management Library	-
deep-log	Logs Management Library	Amazon CloudWatch Logs
deep-notification	Notifications Management Library	Amazon SNS
deep-resource	Resouces Management Library	AWS Lambda, Amazon API Gateway
deep-security	Security Management Library	AWS IAM, Amazon Cognito
deep-validation	Validation Management Library	-

Who is using DEEP Framework?

There are couple examples / web apps that are using DEEP Framework at their core:

DEEP Hello World

DEEP Hello World (https://github.com/MitocGroup/deep-microservices-helloworld) is a web app that show cases a full stack example of using DEEP Microservices in the context of Platform-as-a-Service. Developers can either fork this repository or npm install deepify -g (https://www.npmjs.com/package/deepify) and run in the command line deepify helloworld ~/deep-hello-world.

DEEP Todo App

DEEP Todo App (https://github.com/MitocGroup/deep-microservices-todo-app) is a web app inspired from AngularJS TodoMVC Example (https://github.com/tastejs/todomvc/tree/master/examples/angularjs). It reuses AngularJS module and integrates using DEEP Framework to streamline development and deployment using cloud-based web services.

DEEP Marketplace

DEEP Marketplace (https://www.deep.mg) is Software-as-a-Service, built on top of DEEP, that empowers customers to choose functionality from listed microservices and deploy them together as an web app into their own AWS accounts with just few clicks; as well as empowers developers to create and publish their microservices and monetize them in similar approach to Apple's App Store.

What else is relevant?

Digital Enterprise End-to-end Platform, also known as DEEP, is low cost and low maintenance Platform-as-a-Service powered by abstracted web services from cloud providers like Amazon Web Services. This approach has been labeled as Serverless Architecture.

Appendix A: Serverless Architecture

DEEP is an ecosystem of DEEP Marketplace, DEEP Framework and DEEP CLI, also known as deepify. It enables developers build serverless applications using abstracted services from cloud providers like Amazon Web Services.

Appendix B: DEEP Ecosystem

DEEP aims to remove the heavy lifting from enterprise software through microservices architecture, where developers (let’s label them lego producers) focus only to build microservices (let’s label them lego pieces), while the platform does the rest: comes pre-built and pre-scaled, low-cost and low-maintenance, very secure and very fast. Customers (let’s label them lego consumers) will go to the marketplace, choose the microservices they need and deploy them as web apps into their own accounts on AWS (or other cloud providers).

In summary: We empower lego consumers to license curated lego pieces from a marketplace of lego producers.
