Api development Services

“Building an application with no APIs is basically like building a house with no doors. The API for all computing purposes is how you open the blinds and the doors and exchange information.” – Josh Walker, an analyst at Forrester Research Inc. in Cambridge, Mass.

Increasing demand for complex web applications, quality software solutions, and adaptable web designs has result in a growing acceptance of API development. Application Programming Interface solutions ensure reliable interaction between software components and databases, and play a significant role in success of any business endeavor.

Up-to-date APIs are mainly built on the basis of REST architecture (they use HTTP methods (GET, POST, PUT, PATCH, DELETE) to manage operations and data) with modular structure and authorization/authentication (i. e. OAuth/OAuth 2.0, Passport.js, OpenID, basic access tokens).

We understand that APIs should be extensible, scalable, well-documented, secure, and well-tested. For better experience they should enable users to monitor analytics and be less error-prone in use. All these features are enclosed in LoopBack, enterprise-ready framework for Node.js. Moreover LoopBack comprises lots of ready-to-use features that work out-of-box and in this way speed up API development process.  

LoopBack core benefits:

  • Highly-versatile and open source framework – extensive library of Node.js modules that can be used all together or independently;
  • Fine-grained security – LoopBack allows setting up access data for an app, defining roles and customizing access control lists. Access control modules work right out of the box; moreover, LoopBack provides support for social logins through Passport.js;   
  • Deployment and scalability – to facilitate the deployment process and to seize the opportunities of server space all Node apps can be scaled to multiple hosts or multiple processes on a single host. Such vertical/horizontal scaling or simply clustering ensures zero app downtime and works right out of the box with no coding;
  • Swagger 2.0 compliancy ensures interactive documentation, understandability and client SDK generation. Swagger features the largest stack of API toolchain, while it is an easy and still powerful representation of REST API;
  • API versioning facilitates future updates and streamlines further support. You may not upgrade your app right away, but it is a #1 concern while designing your API. Versioning prevents existing apps from breakage when any changes are made, for instance renaming or deleting a parameter can lead to the risk of bringing down many or all the clients’ systems;
  • LoopBack enables gathering and viewing performance analytics via built-in Arc Tool module. Such approach allows developers to find bottlenecks and trace execution paths;
  • Logging is crucial for auditing and debugging apps, for instance during the production stage log rotation can facilitate handling and storage of log files and save server space. We mainly use Winston with its large set of features and easy-of-use. This logging library enables developers to: use various transports or create custom ones; stream/query logs; perform profiling and handle exceptions; use predefined error levels or create custom ones;
  • LoopBack allows you to control the amount of API requests that can be made within a limited period of time. This is better known as rate limiting.
