—|Welcome to my Go MCU api Project 👋|—

Experiment with GO, learn some new things, with docker / GO / GraphQL.

TODO

• GO
• Gorm
• gqlgen
• Postgres
• graphql
• docker

API-s used for MCU data

• MCU heroku app

Packages used

• github.com/99designs/gqlgen for GraphQl generator
• jwt-go
• Go chi
• gqlparser
• gorm

• Install go
• Install docker / docker-compose
• Set up .env file

with homebrew:

sudo brew install go

with apt-get):

sudo apt-get install golang

install Golang manually or compile it yourself

To run this project, you will need to add the following environment variables to your .env file

PORT= -> your localhost port for the qraphql playground defaults to 8080

DB_HOST= -> localhost
DB_PORT= -> 5432
DB_USER= -> anything
DB_PASSWORD= -> anything
DB_NAME=-> anything

Clone the project

  git clone https://github.com/NorbertRuff/go-mcu-graphql_api

Go to the project directory

  cd go-mcu-graphql_api

Install dependencies

go get

go mod tidy

First start Postgres server with docker compose:

 docker-compose up -d

Finally run the server:

go run server.go

Now navigate to https://localhost:8080 you can see graphiql playground and query the graphql server.

For example:

You can create a user, this command gives back a JWT Token

mutation createuser {
  createUser(
    variables: {
      username: "bob"
      password: "bob"
      email: "bob"
      firstname: "bob"
      lastName: "bob"
    }
  )
}

Login an existing user, this command gives back a JWT Token

mutation {
    login(variables: { username: "bob", password: "bob" })
}

Query all the movies requires: JWT token

query {
    movies
    {
        imdb_id
        movie_id
        title
        overview
        duration
        user {
            user_id
            username
        }
    }

}

You can generate resolvers and types from gql schema configured in gqlgen.yml

go run github.com/99designs/gqlgen generate 

or

go generate 

One great aspect of Golang is, that you can start go applications via go run server.go, but also compile it to an executable with go build server.go. After that you can start the compiled version which starts much faster.

Build your app and synthesize your stacks.

Generates a .build/ directory with the compiled files.
