> Examples for Google's Open Source stack and deployment to the cloud.



The main technologies in the stack are:

* [Angular](https://angular.io/)

* [Protocol Buffers](https://developers.google.com/protocol-buffers/)

* [gRPC](https://grpc.io/)

* [Bazel](https://bazel.build/)



## Hands-on experience

Try these Google Cloud Shell tutorials:



Multi-language code formatting tool built with Bazel:

## Supported languages



Protos, gRPC and Bazel are polyglot. The examples in this repo are mostly in Java and Typescript, but there's support for many other languages:

* gRPC and Protocol Buffers are supported by Google in C++, Java (and Android Java), Python, Go, C#, Objective-C, PHP, Dart, Ruby and JavaScript (incl. Node.js).

* Bazel is supported by Google in Java (incl. Android builds), Objective-C (incl. iOS builds), C++, Go, Dart, Rust, Sass and Scala.

* The community has added support for many others languages. See [this list](https://github.com/google/protobuf/blob/master/docs/third_party.md) for Protocol Buffers and gRPC, and [this one](https://github.com/jin/awesome-bazel#rules) for Bazel.



## Top examples

* Lots of [Protocol Buffer examples](https://github.com/search?utf8=%E2%9C%93&q=repo%3Agoogle%2Fstartup-os+extension%3Aproto&type=Code&ref=advsearch&l=&l=).

* [gRPC-Web](https://github.com/oferb/startup-os-example/tree/master/app): a js client library running in the browser, connected to a gRPC server through an HTTP proxy. Both server and client use gRPC auto-generated stubs to handle communication.

* gRPC [microservices example](https://github.com/google/startup-os/blob/master/tools/reviewer/local_server/LocalServer.java).

* [Docker example](https://github.com/google/startup-os/tree/master/examples/docker): building containers using Bazel (no dockerfile needed!).

* [Kubernetes](https://github.com/google/startup-os/tree/master/examples/k8s): a config file showing how to run a container built with Bazel on k8s.

* [CI example](https://github.com/google/startup-os/tree/master/.circleci): Using CircleCI to run CI (continuous integration) and test all Bazel targets.

* [Firebase](https://firebase.google.com): Java client for storing Protocol Buffers [here](https://github.com/google/startup-os/blob/master/common/firestore/FirestoreProtoClient.java).

* [Dagger](https://github.com/google/dagger): Java Dependency Injection framework  ("Next gen Guice"), see examples [here](https://github.com/google/startup-os/tree/master/examples/dagger).

* [Flogger](https://github.com/google/flogger): Java logger with fluent API, see examples [here](https://github.com/google/startup-os/search?q=com.google.common.flogger.FluentLogger&unscoped_q=com.google.common.flogger.FluentLogger).

* [Android app](https://github.com/google/startup-os/tree/master/examples/android): An Android app built with Bazel and integrated to Firebase.



## Tools

There are several useful tools in the [tools section](https://github.com/google/startup-os/tree/master/tools).



## How to use StartupOS

You can treat StartupOS as a "developer image" with a pre-built setup and associated tools.



You can either:

* Clone this repo and evolve it on your own.

* Treat it as a dependency to your own repo. An example for that is here: https://github.com/oferb/startup-os-example



## Installation

Install [Bazel](https://docs.bazel.build/versions/master/install.html). That's it!



## Build & Test

* Build everything: `./build.sh`

* Run all tests: `./test.sh`



## About monorepos

A monorepo is a software development approach where all code is stored in a single repository. Some things are easier to do in a monorepo, such as sharing a proto file across front-end and backend, some things are harder, such as per-repo control over collaborators, email notifications, commit history etc.

We're working on an approach where multiple repos can act as a single monorepo, while still being separate repos, using multi-repo tooling such as [multi-repo code review](tools/reviewer).



Some good reads about the monorepo approach:

* [trunkbaseddevelopment.com/monorepos](https://trunkbaseddevelopment.com/monorepos/)

* [Why Google stores billions of lines of code in a single repository](https://cacm.acm.org/magazines/2016/7/204032-why-google-stores-billions-of-lines-of-code-in-a-single-repository/fulltext)



## Platforms

While Bazel supports Linux, Mac and Windows, this repo supports Linux and Mac.

If you're on Windows 10, you can use [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/ru-ru/windows/wsl/about).

It gives you a Linux environment, without the overhead of a virtual machine.



#### Installing Windows Subsystem for Linux:

Please follow the [guide](https://docs.microsoft.com/ru-ru/windows/wsl/install-win10).

Note: You may have to do a Windows upgrade. If you need it, it will ask for it at the beginning of the installation.
