Kratos is a microservice-oriented governance framework implements by golang, which offers convenient capabilities to help you quickly build a bulletproof application from scratch, such as:
- The [communication protocol](https://go-kratos.dev/docs/component/api) is based on the HTTP/gRPC through the definition of Protobuf.
- Abstract [transport](https://go-kratos.dev/en/docs/component/transport/overview) layer are support: [HTTP](https://go-kratos.dev/docs/component/transport/http) / [gRPC](https://go-kratos.dev/docs/component/transport/grpc).
- Powerful [middleware](https://go-kratos.dev/en/docs/component/middleware/overview) design, support: [Tracing (OpenTelemetry)](https://go-kratos.dev/docs/component/middleware/tracing)、[Metrics (Prometheus is default)](https://go-kratos.dev/docs/component/middleware/metrics)、[Recovery](https://go-kratos.dev/en/docs/component/middleware/recovery) and more.
- [Registry](https://go-kratos.dev/en/docs/component/registry) interface able to be connected with various other centralized registries through plug-ins.
- The [standard log interfaces](https://go-kratos.dev/en/docs/component/log) ease the integration of the third-party log libs and logs are collected through the *Fluentd*.
- The selection of the content [encoding](https://go-kratos.dev/en/docs/component/encoding) is automatically supported by Accept and Content-Type.
- Multiple data sources are supported for [configurations](https://go-kratos.dev/en/docs/component/config) and dynamic configurations (use atomic operations).
- In the protocol of HTTP/gRPC, use uniform [metadata](https://go-kratos.dev/en/docs/component/metadata) transfer method.
- You can define [errors](https://go-kratos.dev/en/docs/component/errors/) in protos and generate enums with protoc-gen-go.
## Goals
Kratos is accessible, powerful, and provides tools required for large, robust applications.
## Learning Kratos
Kratos has the most extensive and thorough [documentation](https://go-kratos.dev/docs/getting-started/start) and [example](./examples) library of all modern web application frameworks, making it a breeze to get started with the framework.
We also provide a [moderm template](https://github.com/go-kratos/kratos-layout), This template should help reduce the work required to setup up a modern project.
### Goals
Kratos boosts your productivity. With the integration of excellent resources and further support, programmers can get rid of most issues might encounter in the field of distributed systems and software engineering such that they are allowed to focus on the release of businesses only. Additionally, for each programmer, Kratos is also an ideal one learning warehouse for many aspects of microservices to enrich their experiences and skills.
### Principles
* **Simple**: Appropriate design, plain and easy code.

* **Fault-tolerance**: Designed against failure, enhance the understanding and exercising of SRE within Kratos to achieve more robustness.
* **Toolchain**: Includes an extensive toolchain, such as the code generation of cache, the lint tool, and so forth.
## Features
* [APIs](examples/helloworld/helloworld): The communication protocol is based on the HTTP/gRPC through the definition of Protobuf.
* [Errors](examples/errors/api): Both the definitions of error code and the handle interfaces of code generation for tools are defined by the Enum of the Protobuf.
* [Metadata](examples/metadata): In the protocol of HTTP/gRPC, the transmission of service atomic information are formalized by the Middleware.
* [Config](examples/config): Multiple data sources are supported for configurations and integrations such that dynamic configurations are offered through the manner of *Atomic* operations.
* [Logger](examples/log): The standard log interfaces ease the integration of the third-party log libs and logs are collected through the *Fluentd*.
* [Metrics](examples/metrics): *Prometheus* integrated by default. Furthermore, with the uniform metric interfaces, you can implement your own metric system more flexible.
* [Tracing](examples/traces): The OpenTelemetry is conformed to achieve the tracing of microservices chains.
* [Encoding](encoding): The selection of the content encoding is automatically supported by Accept and Content-Type.
* [Transport](transport/transport.go): The uniform plugins for [Middleware](middleware) are supported by [HTTP](examples/http/middlewares)/[gRPC](examples/middleware/main.go).
* [Registry](examples/registry): The interfaces of the centralized registry is able to be connected with various other centralized registries through plug-ins.
* [Validation](examples/validate): Verification rules defined in Protobuf can be supported by HTTP/gRPC service.
* [SwaggerAPI](https://github.com/go-kratos/swagger-api/blob/main/examples/helloworld/server/main.go): Swagger API generated Automatically and embed Swagger UI endpoint can be started by adding [Swagger plugin](https://github.com/go-kratos/swagger-api).
