About

Api-Interfaces is the gRPC protocol for communication between the api-bridge, the api-web, and the generator_server. Additionally, any other client application communicating directly with api-web also use the interfaces generated from this repository.

See here for some development guides.

Getting Started

These instructions will get you an environment setup to build the interface files from the proto source files.

Prerequisites

The following items are needed to develop api-interfaces:

It is recommended to use ssh cloning with this project for git and for go get, although https does appear to work. To force ssh (for github) put the following in your .gitconfig:

[url "ssh://[email protected]/"]
  insteadOf = https://github.com/

Setup and building

After all the prerequisites are installed and available, this project can be setup by the following:

git clone --recurse-submodules [email protected]:Stability-AI/api-interfaces.git
cd api-interfaces
cmake .
cmake --build .

This will produce files for the various languages in gooseai to support the proto files in src. When rebuilding the files it is recommended to do a clean before as there have been instances of not all files being regenerated without it.

🎈 Usage

The generated files are all output in gooseai. How to use these files depends on the programming language being used. The following sections provide details for each of the supported languages.

The files have different usages and not all are required depending on the situation:

Suffix Client Server
_grpc_pb ✔️1 ✔️
_pb_service ✔️2
_pb ✔️ ✔️
  1. Not needed for typescript/javascript clients.
  2. Only needed for typscript/javascripts clients.

Golang

For Golang the interfaces can be added to the project as a normal module require. To add them run:

go get github.com/Stability-AI/api-interfaces@latest

Similarly to update them just run the same command with the short sha of the version to update to. Use them as you would a normal module.

Python

With the current output, the best way to consume these is to add them as a git submodule to your project. It is recommended to use ssh clone when adding the submodule. To update them just checkout the newer version from within the submodule (and remember to commit the submodule change to your project).

To use them make sure the files are on the python path.

Typescript / Javascript

With the current output, the best way to consume these is to add them as a git submodule to your project. It is recommended to use ssh clone when adding the submodule. To update them just checkout the newer version from within the submodule (and remember to commit the submodule change to your project).

To use them make sure they are in a location that can be found by your typescript/javascript files.

NOTE: Typescript requires both the typescript and javascript files to be available.

Other Languages / Custom Build

If not using the CMake defined builds to generate make sure when building from the source proto files that the following proto include paths are set:

  • src/proto
  • src/tensorizer/proto
