ONDEWO S2T APIs

This repository contains the original interface definitions of public ONDEWO APIs that support gRPC protocols. Reading the original interface definitions can provide a better understanding of ONDEWO APIs and help you to utilize them more efficiently. You can also use these definitions with open source tools to generate client libraries, documentation, and other artifacts.

The core components of all the client libraries are built directly from files in this repo using the proto compiler.

For an end-user, the APIs in this repo function mostly as documentation for the endpoints. For specific implementations, look in the following repos for working implementations:

• Python
• Angular
• JavaScript
• TypeScript
• NodeJS

Please note that some of these implementations are works-in-progress. The repo will make clear the status of the implementation.

Overview

ONDEWO APIs use Protocol Buffers version 3 (proto3) as their Interface Definition Language (IDL) to define the API interface and the structure of the payload messages. The same interface definition is used for gRPC versions of the API in all languages.

There are several ways of accessing APIs:

1. Protocol Buffers over gRPC: You can access APIs published in this repository through GRPC, which is a high-performance binary RPC protocol over HTTP/2. It offers many useful features, including request/response multiplex and full-duplex streaming.

2. ONDEWO Client Libraries: You can use these libraries to access ONDEWO Cloud APIs. They are based on gRPC for better performance and provide idiomatic client surface for better developer experience.

Discussions

Please use the issue tracker in this repo for discussions about this API, or the issue tracker in the relevant client if it is language-specific.

Generate gRPC Source Code

API client libraries can be built directly from files in this repo using the proto compiler.

Automatic Release Process

The entire process is automated to make development easier. The actual steps are simple:

TODOs after Pull Request was merged in:

• Checkout master:

  git checkout master

• Pull the new stuff:

  git pull

• (If not already, run the setup_developer_environment_locally command):

  make setup_developer_environment_locally

• Update the ONDEWO_S2T_API_VERSION in the Makefile
• Add the new Release Notes in RELEASE.md in the format:

  ## Release ONDEWO S2T API X.X.X       <---- Beginning of Notes
  
     ...<NOTES>...
  
  *****************                      <---- End of Notes
  

• Commit and push the changes made in RELEASE.md and Makefile
• Release:

  make ondewo_release

---

The make ondewo_release command can be divided into 5 steps:

• cloning the devops-accounts repository and extracting the credentials
• creating and pushing the release branch
• creating and pushing the release tag
• creating the GitHub release

The variable for the GitHub Access Token is inside the Makefile, but the value is overwritten during make ondewo_release, because it is passed from the devops-accounts repo as an argument to the actual release command.

Automatic Release Process - Clients

Every available Client of this API can be released from this repository, to make the release process for major and minor changes easier.

The generic release_client command depends on 4 variables:

• ONDEWO_S2T_API_VERSION -- Current API version
• GENERIC_CLIENT -- specifies SSH git link to client-repository
• RELEASEMD -- position of RELEASE.md inside the client-repository
• GENERIC_RELEASE_NOTES -- template text of client release notes

To release all clients in sequence, use the make release_all_clients command.

Proto Documentation

The documentation for this, and all other APIs and their available versions, can be found on ondewo.github.io. For Offline usage, it can also be found in the docs folder.

As part of the pre-commit hooks, update_githubio is run. It will preemptively stop if:

• The command is not run on the master branch
• There already exists a version-object with the specified version in the data.js of the ondewo.github.io repository

⚠️ This command is dependent on your installation of NPM and NodeJS -- Make sure to install both, or run make setup_developer_environment_locally
