JSON Web Tokens: Downsides, Best Practices and Secure and Robust Alternatives

Leider ist der Eintrag nur auf English verfügbar.JSON Web Tokens (JWTs) nowadays are commonly used for transmitting authentication data in web applications, especially those exhibiting the widespread client-server architecture where you have a fat client / single-page application written in JavaScript as a front-end and a back-end server providing REST endpoints for use by that front-end client. However, while common there are good arguments against this practice. In a nutshell, JWT often are used for storing session data such user authorization and authentication ...

Jess Frazelle: “For the Love of Pipes”

Leider ist der Eintrag nur auf English verfügbar.Somewhat recently, Jess Frazelle wrote about her love of UNIX pipes, a sentiment I wholeheartedly share, to the extent that I think web apps should behave more like Unix programs by making data readily available via APIs so other applications can easily process that data. This, in a nutshell, is the Unix philosophy as stated by Doug McIlroy: Make each program do one thing well. To do a new job, build afresh rather than complicate old ...

HTTP and REST Standards, Protocols and Headers for More Secure and More Robust Applications

Leider ist der Eintrag nur auf English verfügbar.Standards.REST is a website that helps you create better, more robust HTTP- and REST-based applications by providing an overview of existing, proven standards that allow you to build on existing solutions rather than re-invent the wheel yourself. The list of standards mentioned includes OAuth 2.0, the HTTP Caching standard and Application-Level Profile Semantics (ALPS), which - among others - is used extensively in Spring Data REST and Spring HATEOAS. On a closely related note, Stefan ...

More on JSON and REST API Specifications

Leider ist der Eintrag nur auf English verfügbar.Expanding on my previous posts about annotating and validating JSON data structure with JSON Schema defining and documenting REST APIs using Swagger I have two additional suggestions for tools that help you define and build HTTP-based APIs in a less haphazard, more deliberate manner: JSON API: While JSON Schema allows you to annotate and validate JSON-based data types JSON API gives you clear, opinionated guidelines for structuring JSON API responses so you don't have think about those implementation ...

Swagger: A Roundtrip Tool For Creating And Consuming REST APIs

Leider ist der Eintrag nur auf English verfügbar.In this second part of my series on useful tools for developing CRUD applications I'd like to introduce Swagger and Swagger Codegen in particular. Introduce perhaps isn't exactly the right word because first of all Swagger is quite well known in developer circles these days. Secondly, a few months ago I wrote a blog post about how to use Swagger to generate client SDKs for REST APIs. Swagger - originally having originated at Wordnik is ...

Using Swagger to Generate Client SDKs for REST APIs

Leider ist der Eintrag nur auf English verfügbar.These days Swagger is a popular, easy-to-use tool for (semi-)automatically documenting REST APIs on-the-fly. For example, in order to document a REST API created with Spring Boot and Jersey literally all you have to do is add these two entries to your Maven pom.xml: [xml] <dependency> <groupid>io.springfox</groupid> <artifactid>springfox-swagger2</artifactid> <version>2.6.1</version> </dependency> <dependency> <groupid>io.springfox</groupid> <artifactid>springfox-swagger-ui</artifactid> <version>2.6.1</version> </dependency> [/xml] You'll then get a ready-made documentation for all your REST API endpoints. An example of how this looks like can be seen here. While this already is very useful in that it ...

Testing REST Services with REST Assured

Leider ist der Eintrag nur auf English verfügbar.RESTful service testing can be unwieldy and difficult to get started with. Providing a REST API implies using a variety of technologies and techniques such as HTTP, JSON, authentication, various payload transfer mechanisms and content types. This is where a tool that abstracts over these technical details and facilitates their application comes in handy. REST Assured is a high-level DSL for testing REST APIs. It draws upon behaviour-driven development (BDD) and hence makes for ...

ng-admin: Create admin panels from REST APIs

Leider ist der Eintrag nur auf English verfügbar.ng-admin is a helpful AngularJS UI component that automatically creates an admin user interface for RESTful APIs. Such a component is particularly useful for instance with back end applications in enterprise contexts because it allows you to quickly implement and iterate basic user interfaces based on your current model and its API.
