**Shortcuts:**
- [Oat++ High Level Overview](https://oatpp.io/docs/start/high-level-overview/) - Get a quick overview of Oat++ features.
- [Example Project](https://github.com/oatpp/example-crud) - A complete example of a "CRUD" service (UserService) built with Oat++. REST + Swagger-UI + SQLite.### Build Powerful API And Document It With Swagger-UI
See [ApiController](https://oatpp.io/docs/components/api-controller/) for more details.
```cpp
ENDPOINT_INFO(getUserById) {
info->summary = "Get one User by userId";info->addResponse>(Status::CODE_200, "application/json");
info->addResponse>(Status::CODE_404, "application/json");
info->addResponse>(Status::CODE_500, "application/json");info->pathParams["userId"].description = "User Identifier";
}
ENDPOINT("GET", "users/{userId}", getUserById,
PATH(Int32, userId))
{
return createDtoResponse(Status::CODE_200, m_userService.getUserById(userId));
}
```### Access Databases And Keep Your Data Consistent
See [Oat++ ORM](https://oatpp.io/docs/components/orm/) for more details.
```cpp
QUERY(createUser,
"INSERT INTO users (username, email, role) VALUES (:username, :email, :role);",
PARAM(oatpp::String, username),
PARAM(oatpp::String, email),
PARAM(oatpp::Enum::AsString, role))
```## Frequently Asked Questions
### Q: "Oat++" name?
- "Oat" is something light, organic, and green. It can be easily cooked and consumed with no effort.
- "++" gives a hint that it is "something" for C++.### Q: What is the main area of Oat++ application?
Oat++ is used for many different purposes, from building REST APIs that run on embedded devices to
building microservices and highly-loaded cloud applications.But the majority of use cases appears to be in **IoT** and **Robotics**.
### Q: How portable is Oat++?
Theoretically, Oat++ can be **easily** ported everywhere where you have **threads** and **network stack**.
With an additional comparably small effort, it can be ported almost everywhere depending on how
much you strip it and what would be the final binary size.See [supported platforms](https://oatpp.io/supported-platforms/) for additional info.
### Q: What is the size of a minimal Oat++ application?
About **1Mb**, depending on C/C++ std-lib and oatpp version.
### Q: Which Oat++ API to choose, Simple or Async?
Always choose **Simple API** wherever possible. Simple API is more developed and makes the code cleaner.
Async API is designed for small, specific tasks that run at high concurrency levels ex.:
- Serving file downloads to a large number of concurrent users (1K users and more).
- Streaming to a large number of clients (1K or more).
- Websocket Chat servers.For all other purposes use simple API.
