easygraphql-firebase

easygraphql-firebase is global package that will create a GraphQL server connected to your Firebase real-time database just using a GraphQL schema.

Installation

$ npm install easygraphql-firebase -g

Usage

To get started with your GraphQL-Firebase server you need to have:

  • GraphQL schema.
  • Firebase API key.
  • Firebase database url.

Create a GraphQL schema file.

type Student {
  key: ID!
  age: Int!
  name: String!
}

type School {
  key: ID!
  location: String!
  students: Int!
  name: String!
  student: Student!
}

input StudentInput {
  age: Int!
  name: String!
}

input SchoolInput {
  location: String!
  students: Int!
  name: String!
  phone: String!
  student: StudentInput!
}

type Query {
  getStudentByUsername(name: String!): Student!
  getStudents: [Student!]!
  getSchool(name: String!): School!
  getSchools: [School!]!
}

type Mutation {
  createStudent(input: StudentInput!): Student!
  createSchool(input: SchoolInput!): School!
}

Run on your terminal

$ easygraphql-firebase

by default it is going to run the server automatically.

You can set flags to prevent running it automatically, set apiKey, set databaseUrl and also pass the schema name.

$ easygraphql-firebase schema.gql --apiKey=<YOUR_API_KEY> --databaseUrl=<YOUR_DATABASE_URL> --start=false

and select the GraphQL schema you want to use; also, it will ask for some env variables, you can press enter and add them later.

easygraphql-firebase will start creating the whole project, and also it will add to the new schema some new queries, like

type Query {
  ....
  getUserByKey(key: ID!): User
  getSchoolByKey(key: ID!): School
}

also, there is going to be a folder to make tests, it is using easygraphql-tester so, if you want to test your queries and mutations, visit the folder test and add on cases your own tests, add a name to identify them.

const cases = [
  {
    name: 'Should get school by key',
    query: `
      {
        getSchoolByKey(key: "-LTYEa4geFv52c5rzpCS") {
          name
        }
      }
    `,
    expected: true
  }
]

Result

Validate query
    ✓ Should validate the query: Should get school by key

Collections

The collections that are going to be query are going to be the name of the expected type in lowercase with an s at the end.

E.g If you have this query getStudentByUsername(name: String!): Student! the resolver is going to search on Firebase for a collection called students

Run it

To run your project visit the generated folder and run:

$ npm run start

Recommendations

This a beta version, so the recommendations are:

  • Just set one argument to the queries.
  • Add nested fields from the input, if you want to add custom logic, edit the resolvers.
  • Test your queries / mutations.
  • If you are having a lot of records, and you are making a query that returns an array add a limit to it!

Deploying with Now ▲
