Google Developers (previously Google Code) is Google's site for software development tools, application programming interfaces (APIs), and technical resources. The site contains documentation on using Google developer tools and APIs—including discussion groups and blogs for developers using Google's developer products.

There are APIs offered for almost all of Google's popular consumer products, like Google Maps, YouTube, Google Apps, and others.

The site also features a variety of developer products and tools built specifically for developers. Google App Engine is a hosting service for web apps. Project Hosting gives users version control for open source code. Google Web Toolkit (GWT) allows developers to create Ajax applications in the Java programming language.

The site contains reference information for community based developer products that Google is involved with like Android from the Open Handset Alliance and OpenSocial from the OpenSocial Foundation.

Google APIs[edit]

Google offers a variety of APIs, mostly web APIs for web developers. The APIs are based on popular Google consumer products, including Google Maps, Google Earth, AdSense, Adwords, Google Apps and YouTube.[1]

Google Data APIs[edit]

The Google Data APIs[2] allow programmers to create applications that read and write data from Google services. Currently, these include APIs for Google Apps, Google Analytics, Blogger, Google Base, Google Book Search, Google Calendar, Google Code Search, Google Earth, Google Spreadsheets, Google Notebook, and Picasa Web Albums.

Ajax APIs[edit]

Google's Ajax APIs[3] let a developer implement rich, dynamic websites entirely in JavaScript and HTML. A developer can create a map to a site, a dynamic search box, or download feeds with just a few lines of JavaScript.

Ads APIs[edit]

The AdSense and AdWords APIs, based on the SOAP data exchange standard, allow developers to integrate their own applications with these Google services. The AdSense API allows owners of websites and blogs to manage AdSense sign-up, content and reporting, while the AdWords API gives AdWords customers programmatic access to their AdWords accounts and campaigns.

Developer tools and open-source projects[edit]

App Engine[edit]

Google App Engine lets developers run web applications on Google's infrastructure. Google App Engine supports apps written in several programming languages. With App Engine's Java[citation needed] runtime environment, one can build their app using standard Java technologies, including the JVM, Java servlets, and the Java programming language—or any other language using a JVM-based interpreter or compiler, such as JavaScript or Ruby. App Engine also features a dedicated Python runtime environment, which includes a fast Python interpreter and the Python standard library.

Google Plugin for Eclipse[edit]

Google Plugin for Eclipse (GPE) is a set of software development tools that enables Java developers to design, build, optimize, and deploy cloud computing applications. GPE assists developers in creating complex user interfaces, generating Ajax code using the Google Web Toolkit, optimizing performance with Speed Tracer,[4] and deploying applications to Google App Engine. GPE installs into the Eclipse integrated development environment (IDE) using the extensible plugin system.[5] GPE is available under the Google terms of service license.[6]

Google Web Toolkit[edit]

The Google Web Toolkit (GWT) is an open source toolkit allowing developers to create Ajax applications in the Java programming language.[7] GWT supports rapid client–server development and debugging in any Java IDE. In a subsequent deployment step, the GWT compiler translates a working Java application into equivalent JavaScript that programmatically manipulates a web browser's HTML DOM using DHTML techniques. GWT emphasizes reusable, efficient solutions to recurring Ajax challenges, namely asynchronous remote procedure calls, history management, bookmarking, and cross-browser portability. It is released under the Apache License version 2.0.

OR Tools[edit]

Google OR Tools[8] provides programming language wrappers for Operational Research tools such as optimisation and constraint solving.

Project hosting[edit]

Google Code runs a project hosting service[9] that provides revision control offering Subversion, Mercurial[10] and Git[11] (transparently implemented using BigTable as storage), an issue tracker, and a wiki for documentation. The service is available and free for all OSI-approved Open Source projects (as of 2010, it is strongly recommended but no longer required to use one of the nine well-known open source licenses: Apache, Artistic, BSD, GPLv2, GPLv3, LGPL, MIT, MPL and EPL). The site limits the number of projects one person can have to 25.[12] Additionally, there is a limit as to the number of projects that may be created in one day, a 200MB default upload file size limit, which can be raised, and a 5GB per project total size limit.[13] The service provided a file download feature, but on May 2013 the creation of new downloads was disabled, with plans to disable it altogether on January 14, 2014.[14]

Gears[edit]

Gears was beta software offered by Google to enable offline access to services that normally only work online. It installed a database engine, based on SQLite, on the client system to cache data locally. Gears-enabled pages used data from this local cache rather than from the online service. Using Gears, a web application may periodically synchronize the data in the local cache with the online service. If a network connection is not available, the synchronization is deferred until a network connection is established. Thus Gears enabled web applications to work even though access to the network service is not present. Gears is currently discontinued.

Access restrictions[edit]

Error-message seen by someone attempting to access code.google.com from an OFAC-restricted country.

Accessing Google Code website and its hosted contents is banned from countries on the United States Office of Foreign Assets Control sanction list, including Cuba, Iran, North Korea, Sudan and Syria.[15]

Google developer events[edit]

Google I/O is Google's largest developer event, which, since 2009, has been held in the Moscone Center in San Francisco.

Google Developer Day is Google's annual developer event.

Google Summer of Code is a mentoring program to find students for open source projects. In 2007, the program received nearly 6,200 applications.

Google Code Jam is an international programming competition.
