Postman socketio11/4/2023 Postman displays the latest information to viewers of the collection in real time. Postman keeps a record of the update in version control stored with your profile.You add a parameter to the Postman collection.Every user action in Postman results in a series of API calls handled over websocket connections, following a publish-subscribe pattern, so that information flows in real time between users and across teams.įor example, this is what happens when you log in to Postman and update a collection: It has the daunting task of synchronizing all the activity in the Postman client on your local machine with Postman servers. One of the Postman services that grew too big to be managed efficiently is called Sync. When this happens at Postman, many engineers across different teams end up contributing to the code, requiring careful coordination across every team for each and every update. These services allow the team to rapidly iterate, but may start acting more like a bloated monolith, a big ball of mud, or whatever you want to call these unwieldy creatures. Unfortunately, a service can sometimes grow too big, providing a breadth of seemingly unrelated services. Most microservices at Postman are loosely coupled so they can evolve independently of other teams. The Server Foundation team is an example of a functional team at Postman that creates and manages stuff used across the entire engineering organization This team is also where the resident AWS and infrastructure experts reside. These engineers create the utilities used by other squads to build, ship, and observe their own features. The Server Foundation team is an example of a functional team at Postman. While most engineers work in squads, some work in functional teams that build components shared across the entire engineering organization. Guided by the principles of domain-driven design, each squad develops internal microservices and Postman features for Postman users. Most development teams at Postman work in cross-functional squads focused on a single core domain, such as documentation or version control. Here is the story of how Postman engineers developed the Bifrost websocket gateway by chipping away at a service that grew too big. That is the natural evolution of software design. Operating in the real world means occasionally re-evaluating old ways of thinking to adjust to new circumstances. Similarly, and equally magically, our Bifrost websocket gateway lets Postman clients instantaneously connect to Postman services.Īs I’ve previously shared in How Postman Engineering Does Microservices Today, all software architectures are a continuous work in process. In the Marvel Cinematic Universe, Bifrost is the name of the rainbow bridge that allows instantaneous travel between the realms of gods and humanity.
