Run dev harness

This repo includes a sample application which is used for testing and development of the SignalR client and the server.

Open the tanka-graphql.sln and start the graphql.dev.chat.web project. This will start a simple chat server using the tanka.graphql.server.

Start the client by following instructions below:

# Install dependencies
src\graphql.server.link> yarn install

# Link the server-link
src\graphql.server.link> yarn link

# Watch for source changes and recompile the link
src\graphql.server.link> yarn watch

# Install dependencies
dev\graphql.dev.chat.ui> yarn install

# Use the linked server-link
dev\graphql.dev.chat.ui> yarn link @tanka/tanka-graphql-server-link

# Watch for source changes and recompile the sample
dev\graphql.dev.chat.ui> yarn start
