# Welcome to `include/grpc/impl/codegen` |
||||
|
||||
## Why is this directory here? |
||||
|
||||
This directory exists so that generated C++ code can include selected files upon |
||||
which it depends without having to depend on the entire gRPC C++ library. This |
||||
directory thus exists to support `include/grpcpp/impl/codegen`. This constraint |
||||
is particularly relevant for users of bazel, particularly if they use the |
||||
multi-lingual `proto_library` target type. Generated code that uses this target |
||||
only depends on the gRPC C++ targets associated with these header files, not the |
||||
entire gRPC C++ codebase since that would make the build time of these types of |
||||
targets excessively large (particularly when they are not even C++ specific). |
||||
|
||||
## What should user code do? |
||||
|
||||
User code should *not* include anything from this directory. Only generated code |
||||
and gRPC library code should include contents from this directory. C++ user code |
||||
should instead include contents from the main `grpcpp` directory or its |
||||
accessible subcomponents like `grpcpp/support`. It is possible that we may |
||||
remove this directory altogether if the motivations for its existence are no |
||||
longer strong enough (e.g., if the gRPC C++ library no longer has a need for an |
||||
`impl/codegen` directory of its own). |

target type or if the additional overhead of depending on gRPC C++ is not high). |
