Formats GraphQL schema definition language (SDL) document.
As schema grows in size, it becomes desirable to automate schema organisation. The primary function of format-graphql is to sort definitions and fields in an alphabetical order, therefore enabling predictable discovery and grouping of related schema entities.
Alphabetically sorts definitions, fields and arguments.
Input:
type Query {
bananas: [Banana!]!
apples: [Apple!]!
}
type Apple {
name: String!
id: ID!
}
type Banana {
name: String!
id: ID!
}
Output:
type Apple {
id: ID!
name: String!
}
type Banana {
id: ID!
name: String!
}
type Query {
apples: [Apple!]!
bananas: [Banana!]!
}

-
schema: string -
options(optional): object:{ sortDefinitions?: boolean, sortFields?: boolean, sortArguments?: boolean, }
import {formatSdl} from 'format-graphql';
formatGraphql('type Foo { bar: String }');I recommend using husky to setup a pre-commit hook that would format the schema, e.g.
"husky": {
"hooks": {
"pre-commit": "format-graphql --write true src/schema.graphql"
}
