Features

restfb has been designed with several objectives in mind. The most important of these are defined as follows.

Zero runtime dependencies

You don't need to include additional libraries in your project. There are no dependency conflicts. In addition, RestFB is highly portable and can be used in both Android projects and normal Java applications.

Maximal extensibility

Although we provide a standard implementation for our core components, each component can be replaced with a custom implementation. This allows RestFB to be easily integrated into any kind of project. Even Android projects are supported.

Minimal public API

TThe RestFB API is really minimal and you only need to use one method to get information from Facebook and one to publish new items to Facebook. We provide default implementations for all the core components, so you can drop the jar into your project and be ready to go.

Simple metadata-driven configuration

Our Facebook types are simple POJOs with special annotations. This configuration is designed for ease of use and can be used to define custom types very easily.

Download

RestFB can be downloaded from Github or used as a Maven dependency. There is also a sample project on Github.

Contribute

Working with source code

It's easy to work directly with the RestFB source code. This is necessary if you need to use an unreleased version or want to contribute to the code. It's very important to know that RestFB is using the Lombok code generator. All types use special annotations to generate the boilerplate code for the setters and getters. It's important to know that we made the design decision to handle Lists and Maps differently - the Lombok annotations are not used for them and we provide add(), remove() and getList() methods. The returned List is immutable to prevent inner Lists and Maps from being altered by other objects. This idea can be found at Martin Fowler's blog.

You need to install Lombok in your IDE to compile RestFB. If you don't, you will see a lot of compilation errors and missing methods. More information about installing Lombok for different IDEs can be found here.

Contributing to RestFB

Contributing code is an essential part of open source and we try to make this as easy as possible. All you need to do is fork RestFB on Github and send us a pull request. We have some requirements to merge the pull request into our Dev branch.

  • The code must be formatted with our code formatter (have a look at the misc folder)
  • The code should conform to our general design standards (if you feel it's necessary to go against the grain, please ask us first!)
  • Existing unit tests have to run without error (we use CI)
  • The pull request should be mergeable
  • Explain why you made the change and why it's beneficial
  • jUnit tests are a big plus
  • The pull request should be based on the dev branch
  • Group and squash your commits, fewer are better

These conditions are defined to make everyone's lives easier and cause fewer conflicts when merging a pull request into the dev branch. If you put some work in a pull request and it meets our requirements, it's very likely we'll merge it the same day.

If you don't want to dive into the RestFB code you can open an issue. We are very grateful for every issue you open, no matter what kind it is. We fix bugs, explain Facebook and answer your questions about RestFB and Facebook.
