Features

RestFB is designed with several goals in mind. The key goals are defined as follows.

Minimal public API

The RestFB API is really minimal and you simply need to use a method to fetch information from and one to publish new items to Facebook. We provide default implementations for all core components, so you can drop the jar in your project and are ready to go.

Maximal extensibility

Although we provide a default implementation for our core components, every component may be replaced with a custom implementation. Therefore RestFB integrates flawlessly in every kind of project. Even Android projects are supported.

Simple metadata-driven configuration

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

Zero runtime dependencies

You don't need to have any additional libraries included in your project. You will not run into trouble with dependency clashes. In addition, RestFB is highly portable and usable in both Android projects and normal Java applications.

Download

RestFB may be downloaded from Github or used as Maven dependency. Additionally, an example project can be found on Github.

Download from Github

Newest Version of the library is available via RestFB's home on Github.

Download from Maven

RestFB is a single JAR - just drop it into your app and you're ready to go. Download it from Maven Central:
maven central restfb version

Restfb example

You can find a sample project at Github. That project can help you get up and running quickly.

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 have to install Lombok in your IDE to compile RestFB. If you don't do this, you will see a lot of compilation errors and missing methods. Further information regarding the installation of Lombok for different IDEs can be found here.

Contributing to RestFB

Contributing code is a essential part of open source and we try to make this as easy as possible. You only need to fork RestFB at Github and send us a pull request. We have some prerequisites to merge the pull request in 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 may open an issue. We are very thankful for every issue you open, no matter what kind it is. We solve bugs, explain Facebook, and answer your RestFB and Facebook questions.
