This is the repository for code samples used in the public AWS documentation. The examples use the AWS Software Developer Kits (SDKs) for the supported programming languages. For more information, see Tools to Build on AWS.
The code examples are organized by programming language. For instance, all of the examples for the AWS SDK for Java Developer Guide are kept in the java directory.
You can also try using the preview of our use case index of examples (and let us know what you think about it).
Inside each of the language-specific directories, you'll find a README file that explains how to build and run the examples contained within it.
The example code inside the language-specific directories is organized by the AWS service abbreviation ("s3" for Amazon S3 examples, and so on).
To propose a new code example for the AWS documentation team to consider working on, create a new request.
The AWS documentation team is looking to produce code examples that cover broader scenarios and use cases, versus simple code snippets that cover only individual API calls.
From time to time, the AWS documentation team will select some of these proposals to begin working on. To view their decisions, see the code examples roadmap. If you feel strongly about seeing the timeline of a particular proposal accelerated or the scope of a particular proposal expanded or focused, be sure to +1 the related issue, add comments to it, or both, and the team will take this under consideration.
The AWS documentation team typically moves accepted proposals in the roadmp from the Wish List stage to the Backlog stage, then to the In Progress stage, and finally to the Recently Completed stage. The Wish List stage represents proposals that the team might begin working on at some point in the future but with no expected timeline, while the Backlog stage represents proposals that the team will likely begin working on soon. To view the team's progress, see the code examples roadmap.
If you plan to contribute examples for use in the documentation (the purpose of this repository), please read this section carefully so that we can work together more effectively. For process instructions and additional guidance, see the Guidelines for contributing.
Make sure that the code can be built and run. There's nothing more frustrating in developer documentation than code examples that don't work. Build the code and test it before submitting it!
Do not include personal account data, keys or IDs in your examples. Code should obtain access keys from the standard SDK credentials and config files, use environment variables or external data files, or query the user for this information.
Format code lines to 80 characters. Long lines can be enclosed in a scrollable box for HTML, but in a PDF build, long lines will often spill off the side of the page, making the code unreadable. If your code includes long text strings, consider breaking these into smaller chunks and concatenating them together.
Use short(er) variable names. To aid in readability and to help keep line length down, use short yet descriptive names for variables. Do not simply mimic class names when creating variables that represent an object of that class. It nearly always results in excessively long variable names, making it difficult to keep code lines within 80 characters.
Use spaces, not tabs, for indentation. Tabs are variable-length in most editors, but will usually render as 8 characters wide in printed documentation. Always use spaces to ensure consistent formatting in printed code.
You can ignore this rule for makefiles, which may require the use of tabs, but these are typically only used for building examples, and are not included in documentation.
Minimize the use of comments. Code is ignored for translation, so comments in code are not translated for the printed documentation's target language. Comments should not be needed in most code used for documentation, since the goal is clarity and ease of understanding. By making code self-explanatory, you'll make better code for documentation and reduce the need to add comments.
Place comments on separate lines from code. If you must add a comment for explanation or any other purpose, make sure that it's placed on a separate line from code (not inline). This allows readers of the source file to read the comment, yet it can be stripped out when including snippets from the file within documentation.
