Pragmatic REST: APIs without hypermedia and HATEOAS

If you’re not using HATEAOS then you’re not using REST. That’s true enough, but in many cases adopting HATEOAS doesn’t deliver much value beyond architectural purity.

Using the REST API connector as a data source in Informatica Cloud

It can be pretty straightforward to read REST API resources using Informatica Cloud – so long as you know which levers to pull and your data is in a sympathetic format.

REST APIs don’t need a versioning strategy – they need a change strategy

Change in an API is inevitable. Attempting to manage this change through version numbering usually creates more problems than it solves.

Microservices, REST and the distributed big ball of mud

The “big ball of mud” describes a system architecture that is sprawling, sloppy and haphazard. That’s precisely how you’d describe some emerging microservice architectures.

Why REST is not a silver bullet for service integration

REST is sometimes described as the next “evolutionary step” in service integration. The problem is that REST provides too much of a “dumb pipe” to support genuinely decoupled, fault-tolerant service integration.

The RESTafarian flame wars – common disagreements over REST API design

Debates on the finer points of REST can bring out the worst in people as they seek to define what is and is not “RESTful”. In most cases the debate is unlikely to make the difference between success and failure for an API.

Parsing OData queries for decoupled data entities in ASP.NET WebApi

If you adopt OData you don’t have to expose the entire range of query functionality for every resource. You can use the OData libraries to parse queries and interrogate data directly.

Messaging shouldn’t be used for queries

When developers first start using messaging they can be tempted to use it as a brand new hammer for every nail. Messaging brings a lot to the party, but it isn’t necessarily a suitable transport for fast, synchronous query processing.

Using a tolerant reader for web service integrations in .Net

Using version tolerant readers can help you to cope with changes to service contracts though this does come at the expense of a weaker contract. The approach is more appropriate for fluid services that are prone to frequent change.

Hackable URIs may look nice, but they don’t have much to do with REST and HATEOAS

Structured and “Hackable” URIs are a staple part of SEO-friendly websites. Although developers generically expect to see them in HTTP-based APIs, they should be irrelevant to consumers of a fully RESTful API that leverages HATEOAS.

Can APX help in developing usable and accessible APIs?

Given how important APIs have become in driving the reach of applications and services, it’s surprising how little investment is made in the usability of APIs as opposed to UIs. Perhaps the principals and techniques used by UX should be applied to developing more effective APIs…

Netflix has abandoned OData – does the standard have a future without an ecosystem?

Netflix have closed their OData catalogue and EBay seem to have quietly put their implementation out to grass. With a shrinking ecosystem and no marquee services, does Microsoft’s data standard have a future?

REST services may not have standards, but they should follow conventions

REST is more of an architectural style than a set of standards. That said, a service should follow certain conventions if it is to be predictable and simple to work with.
