Creating a GraphQL server with Golang. In this project I implemented a simple library system database, where you can query to database with GraphQL. It uses sqlite3 to create the main database, and then it will create the library schema for books and authors. After that you can submit your queries in GraphQL type and get the response from the server.
One important thing to note is that GraphQL is not a query language like our traditional SQL. It is an abstraction that sits in-front of our APIs and is not tied to any specific database or storage engine. This is actually really cool. We can stand up a GraphQL server that interacts with existing services and then build around this new GraphQL server instead of having to worry about modifying existing REST APIs.
Execute server:
go run main.goSetup server using docker:
docker build . -t my-go-graphql
docker run -d -p 5000:5000 my-go-graphqlAfter that you can check the server status in localhost:5000
If you get the guid page, you are good to go. You can submit your queries by the following request:
curl -X POST -H "Content-Type: application/json" \
-d '{"query": "[GraphQL query]"' \
https://localhost:5000/queryJust insert your GraphQL query into request.
