Overview

Each rule has emojis denoting:

• 📄 if the rule applies to schema documents
• 📦 if the rule applies to operations
• 🚀 graphql-eslint rule
• 🔮 graphql-js rule
• 🔧 if some problems reported by the rule are automatically fixable by the --fix command line  option
• 💡 if some problems reported by the rule are manually fixable by editor suggestions 

Name	Description	Config	📄 / 📦	🚀 / 🔮	🔧 / 💡
alphabetize	Enforce arrange in alphabetical order for type fields, enum values, input object fields, operation selections and more.		📄 📦	🚀	🔧
description-style	Require all comments to follow the same style (either block or inline).		📄	🚀	💡
executable-definitions	A GraphQL document is only valid for execution if all definitions are either operation or fragment definitions.		📦	🔮
fields-on-correct-type	A GraphQL document is only valid if all fields selected are defined by the parent type, or are an allowed meta field such as __typename.		📦	🔮	💡
fragments-on-composite-type	Fragments use a type condition to determine if they apply, since fragments can only be spread into a composite type (object, interface, or union), the type condition must also be a composite type.		📦	🔮
input-name	Require mutation argument to be always called “input” and input type to be called Mutation name + “Input”.		📄	🚀	💡
known-argument-names	A GraphQL field is only valid if all supplied arguments are defined by that field.		📄 📦	🔮	💡
known-directives	A GraphQL document is only valid if all @directives are known by the schema and legally positioned.		📄 📦	🔮
known-fragment-names	A GraphQL document is only valid if all ...Fragment fragment spreads refer to fragments defined in the same document.		📦	🔮
known-type-names	A GraphQL document is only valid if referenced types (specifically variable definitions and fragment conditions) are defined by the type schema.		📄 📦	🔮	💡

match-document-filename	This rule allows you to enforce that the file name should match the operation name.		📦	🚀
naming-convention	Require names to follow specified conventions.		📄 📦	🚀	💡
no-anonymous-operations	Require name for your GraphQL operations. This is useful since most GraphQL client libraries are using the operation name for caching purposes.		📦	🚀	💡
no-deprecated	Enforce that deprecated fields or enum values are not in use by operations.		📦	🚀	💡
no-duplicate-fields	Checks for duplicate fields in selection set, variables in operation definition, or in arguments set of a field.		📦	🚀	💡

no-root-type	Disallow using root types mutation and/or subscription.		📄	🚀	💡
no-scalar-result-type-on-mutation	Avoid scalar result type on mutation type to make sure to return a valid state.		📄	🚀	💡
no-typename-prefix	Enforces users to avoid using the type name in a field name while defining your schema.		📄	🚀	💡
no-undefined-variables	A GraphQL operation is only valid if all variables encountered, both directly and via fragment spreads, are defined by that operation.		📦	🔮
no-unreachable-types	Requires all types to be reachable at some level by root level fields.		📄	🚀	💡
no-unused-fields	Requires all fields to be used at some level by siblings operations.		📄	🚀	💡
no-unused-fragments	A GraphQL document is only valid if all fragment definitions are spread within operations, or spread within other fragments spread within operations.		📦	🔮
no-unused-variables	A GraphQL operation is only valid if all variables defined by an operation are used, either directly or within a spread fragment.		📦	🔮
one-field-subscriptions	A GraphQL subscription is valid only if it contains a single root field.		📦	🔮
overlapping-fields-can-be-merged	A selection set is only valid if all fields (including spreading any fragments) either correspond to distinct response names or can be merged without ambiguity.		📦	🔮
possible-fragment-spread	A fragment spread is only valid if the type condition could ever possibly be true: if there is a non-empty intersection of the possible parent types, and possible types which pass the type condition.		📦	🔮
possible-type-extension	A type extension is only valid if the type is defined and has the same kind.		📄	🔮	💡
provided-required-arguments	A field or directive is only valid if all required (non-null without a default value) field arguments have been provided.		📄 📦	🔮

require-description	Enforce descriptions in type definitions and operations.		📄	🚀
require-field-of-type-query-in-mutation-result	Allow the client in one round-trip not only to call mutation but also to get a wagon of data to update their application.		📄	🚀
require-import-fragment	Require fragments to be imported via an import expression.		📦	🚀	💡
require-nullable-fields-with-oneof	Require input or type fields to be non-nullable with @oneOf directive.		📄	🚀

require-selections	Enforce selecting specific fields when they are available on the GraphQL type.		📦	🚀	💡
require-type-pattern-with-oneof	Enforce types with @oneOf directive have error and ok fields.		📄	🚀
scalar-leafs	A GraphQL document is valid only if all leaf fields (fields without sub selections) are of scalar or enum types.		📦	🔮	💡
selection-set-depth	Limit the complexity of the GraphQL operations solely by their depth. Based on graphql-depth-limit .		📦	🚀	💡
strict-id-in-types	Requires output types to have one unique identifier unless they do not have a logical one. Exceptions can be used to ignore output types that do not have unique identifiers.		📄	🚀
