Getting Started 🚀

For an overview of gRPC in general, checkout the official DOCS here. There are clear and simple walkthroughs for each of the 12 programming languages supported by gRPC. Butter, Yodelay’s furry mascot, recommends choosing your preferred language, uploading the .proto file into yodelay and then using those examples to walk through this readme.

git clone
cd Yodelay
npm install

Test your endpoints locally ☄

Navigate to the Yodelay folder in your terminal and run the following command:

npm start

NPM start will build the bundle, make it available in your browser at localhost:3000, start the client server on port 4000, and start a demo grpc server at localhost:8080

Go to your browser and enter the URL:
