Feathers: Microservice Framework Built in The Spirit Of Express

A framework for real-time applications and REST APIs with JavaScript and TypeScript

Feathers is a lightweight web-framework for creating real-time applications and REST APIs using JavaScript or TypeScript.

Feathers can interact with any backend technology, supports over a dozen databases and works with any frontend technology like React, VueJS, Angular, React Native, Android or iOS.

Getting started

You can build your first real-time and REST API in just 4 commands:

$ npm install -g @feathersjs/cli
$ mkdir my-new-app
$ cd my-new-app/
$ feathers generate app
$ npm start

Documentation

The Feathers docs are loaded with awesome stuff and tell you every thing you need to know about using and configuring Feathers.

Testing Microservices Applications

The shift towards microservices and modular applications makes testing more important and more challenging at the same time. You have to make sure that the microservices running in containers perform well and as intended, but you can no longer rely on conventional testing strategies to get the job done.

This is where new testing approaches are needed. Testing your microservices applications require the right approach, a suitable set of tools, and immense attention to details. This article will guide you through the process of testing your microservices and talk about the challenges you will have to overcome along the way. Let’s get started, shall we?

A Brave New World

Traditionally, testing a monolith application meant configuring a test environment and setting up all of the application components in a way that matched the production environment. It took time to set up the testing environment, and there were a lot of complexities around the process.

Testing also requires the application to run in full. It is not possible to test monolith apps on a per-component basis, mainly because there is usually a base code that ties everything together, and the app is designed to run as a complete app to work properly.

Microservices running in containers offer one particular advantage: universal compatibility. You don’t have to match the testing environment with the deployment architecture exactly, and you can get away with testing individual components rather than the full app in some situations.

Of course, you will have to embrace the new cloud-native approach across the pipeline. Rather than creating critical dependencies between microservices, you need to treat each one as a semi-independent module.

The only monolith or centralized portion of the application is the database, but this too is an easy challenge to overcome. As long as you have a persistent database running on your test environment, you can perform tests at any time.

Keep in mind that there are additional things to focus on when testing microservices.

• Microservices rely on network communications to talk to each other, so network reliability and requirements must be part of the testing.
• Automation and infrastructure elements are now added as codes, and you have to make sure that they also run properly when microservices are pushed through the pipeline
• While containerization is universal, you still have to pay attention to specific dependencies and create a testing strategy that allows for those dependencies to be included

Test containers are the method of choice for many developers. Unlike monolith apps, which lets you use stubs and mocks for testing, microservices need to be tested in test containers. Many CI/CD pipelines actually integrate production microservices as part of the testing process.

Contract Testing as an Approach

As mentioned before, there are many ways to test microservices effectively, but the one approach that developers now use reliably is contract testing. Loosely coupled microservices can be tested in an effective and efficient way using contract testing, mainly because this testing approach focuses on contracts; in other words, it focuses on how components or microservices communicate with each other.

Syntax and semantics construct how components communicate with each other. By defining syntax and semantics in a standardized way and testing microservices based on their ability to generate the right message formats and meet behavioral expectations, you can rest assured knowing that the microservices will behave as intended when deployed.

Top Microservices Frameworks

Choose right framework for microservices architecture.

Microservices architecture is a methodology wherein fragment monolithic single application into small applications and services which executes lightweight applications. Business capabilities and independently deployable models are the primary goals for Microservices development. Microservices architecture built using different programming languages and deployed them and connect.

Benefits of Microservices

• Adoption of New technology and process.
• Independent scaling of applications.
• Cloud-ready.
• Seamless integrations.
• Effective Hardware utilization.
• Service level Security.
• API-based functions for reuse effectively.
• Independently Develop and Deploy applications.

Selection Criteria for Framework Selection

The following are some of the critical aspects that can be considered while choosing the proper framework:

• Popularity — Measured by the industry acceptance of the framework based on the number of customers who have made the framework an enterprise standard. The other indicators that could help are the availability of documentation and the number of skilled resources available in the market.
• Maturity of the Community — Reputation of the supporting the framework such as Apache or Google, or Spring. Maturity of the framework in terms of community / commercial support and the frequency of releases to fix issues and add new features.
• Ease of Development — Frameworks selected application development easy and enhances developer productivity. IDEs and tools that support the frameworks also play an essential role in rapid application development.
• Learning Curve — Availability of documentation in the form of tutorials, best practices, and solutions for typical problems play an important role in reducing the learning curve and improving overall developer productivity.
• Architecture Support — Frameworks provide code modules and interfaces with built-in design patterns that remove the coding complexity from application developers.
• Support of Automation — Framework support for automating the tasks related to build and deploy of microservices
• Independent Deployments — Framework has to support dour aspects of independent deployment — upward compatibility, downward compatibility, reusability, and portability
• Continuous Integration — Developers integrate code into a shared repository frequently, preferably several times a day. Each integration can then verified by an automated build and automated tests framework to support.
