GoLang GraphQL MongoDB CRUD Project

This project is a comprehensive example of building a GraphQL API in GoLang for performing CRUD (Create, Read, Update, Delete) operations with a MongoDB database. It serves as a practical reference for developers looking to create efficient and scalable GraphQL-based applications.

1. Create a new folder for the Project mkdir graphql
2. Mod init your project, give it whatever name you like go mod init github.com/athunlal/graphql
3. Get gql gen for your project go get github.com/99designs/gqlgen
4. Add gqlgen to tools.go printf '// +build tools\npackage tools\nimport _ "github.com/99designs/gqlgen"' | gofmt > tools.go
5. Get all the dependencies go mod tidy
6. Initialize your project go run github.com/99designs/gqlgen init
7. After you've written the graphql schema, run this - go run github.com/99designs/gqlgen generate
8. After you've built the project, these are the queries to interact with the API -
