MUTATIONS

In GraphQL - mutations are the ideal things that are used to make DELETE, UPDATE or CREATE request to the database. Just like in RESTful APIS where you used PUT/GET/DELETE/POST requests to access the database, in GraphQL you use mutations to perform the equivalent actions that you use in RESTful APIS.

Below are the mutations used in this project.

Mutations used to ADD / UPDATE / DELETE records on Company Model for the MongoDB 👇.

mutation {
#---- COMPANY MODEL ----
# --- ADD NEW PRODUCTION COMPANY ---
  addProductionCompany(name:"New Cinema") {
    message
  }
# --- UPDATE PRODUCTION COMPANY NAME ( INFO )---
  updateProductionCompanyInfo(oldName:"Neto", newName:"Betty") {
    message
  }
# --- DELETE PRODUCTION COMPANY ---
  deleteProductionCompany(_id: "610903cfeae8f11fc4dac940") {
    message
  }

#---- COMPANY MODEL ----
# --- ADD NEW MOVIE ---
  addMovie(title:"Stranger Things", prodCompany:"NetFlix") {
    message
  }
# --- DELETE MOVIE ---
  deleteMovie(_id: "61095a76e6716d35ea15ef71") {
    message
  }
# --- UPDATE MOVIE TITLE ---
  updateMovieTitle(_id: "61095a76e6716d35ea15ef71", title: "Netflix") {
    message
  }
# --- UPDATE MOVIE PRODUCTION COMPANY ---
  updateMovieProdCompany(_id: "61095a76e6716d35ea15ef71", prodCompany:"Netflix") {
    message
  }
}

Queries.

In GraphQL - Queries are used to ask/request for data or information. Queries are equivalent to GET request in RESTful APIS.

Below are the queries used in this project.

Queries used to look for records on Company And Movie Model for the MongoDB 👇.

{
# --- Get All Production Companies With Their Movies ---
  companies {
    name
    _id
    movies {
      title
    }
  }
# --- Get All Movies ---
  movies {
    _id
    title
    prodCompany
  }
# --- Search Movie Using Movie Title ---
  searchMovie(title:"Blades") {
    _id
    prodCompany
  }
# --- Search Movie Using Movie Production Company And Get All Their Movies---
  searchProdCompany(name:"Netflix") {
    name
    movies {
      title
    }
  }
}
