Alternatives and detailed information of graphql-gateway

graphql-gateway - SDL-based GraphQL gateway for REST and GraphQL-based micro-services

⚠️ Project is a POC and at very early experimental/WIP stage! ⚠️

Getting Started

You can use graphql-gateway as a docker container:

docker run -it -p 8080:8080 -v $(pwd):/schema tenshi/graphql-gateway

For you convenience, you can define an alias for it and put it in your .bashrc:

alias graphql-gateway='docker run -it -p 8080:8080 -v $(pwd):/schema tenshi/graphql-gateway'

After this is done, you can start the sever just by executing graphql-gateway - the server will automatically read the schema from all *.graphql files in a current working directory and watch them for changes.

There is also a fat JAR available on release notes: graphql-gateway.jar.

Configuration

Docker container accepts a number of environment variables:

General
- PORT - Int - server port (by default 8080)
- BIND_HOST - String - bind host (by default 0.0.0.0)
- GRAPHIQL - Boolean - enable/disable GraphiQL (by default true)
- PLAYGROUND - Boolean - enable/disable graphql-playground which replaces GraphiQL (by default true)
- INCLUDE_DIRECTIVES - List of String - include specific directive sets (available directive sets are: http, graphql, faker, basic)
- EXCLUDE_DIRECTIVES - List of String - exclude specific directive sets (available directive sets are: http, graphql, faker, basic)
Query tracing and logging
- SLOW_LOG_ENABLED - Boolean - enable/disable logging of slow queries (by default true)
- SLOW_LOG_THRESHOLD - FiniteDuration - SlowLog extension threshold (by default 10 seconds)
- SLOW_LOG_EXTENSION - Boolean - enable/disable SlowLog GraphQL extension (by default false)
- SLOW_LOG_APOLLO_TRACING - Boolean - enable/disable Apollo tracing GraphQL extension (by default true)
Schema live reloading
- WATCH_ENABLED - Boolean - enable/disable schema file reloader (by default true)
- WATCH_THRESHOLD - FiniteDuration - internal poll interval for file watcher (by default 50 millis)
- WATCH_PATHS - List of String - which directories to watch for schema files (by default ".")
- WATCH_GLOB - List of String - which files are the schema files (by default "**/*.graphql")
Limits
- LIMIT_COMPLEXITY - Double - query complexity limit (by default 10000)
- LIMIT_MAX_DEPTH - Int - max query depth (by default 15)
- ALLOW_INTROSPECTION - Boolean - enable/disable GraphQL introspect API (by default true)

The full configuration can be found in the reference.conf.

Supported SDL Directives

Schema definition is based on GraphQL SDL. SDL syntax allows you to define full GraphQL schema with interfaces, types, enums etc. In order to provide resolution logic for the fields, you can use directives described below. Directives will define how fields will behave. By default (if no directive is provided), field resolve function will treat a contextual value as a JSON object and will return its property with the same name. (check out an example schema)

`@httpGet`

directive @httpGet(
  url: String!, 
  headers: [Header!],
  delegateHeaders: [String!] 
  query: [QueryParam!], 
  forAll: String) on FIELD_DEFINITION

input Header {
  name: String!
  value: String!
}

input QueryParam {
  name: String!
  value: String!
}

Provides a way to resolve the field with a result of a GET HTTP request.

Supports following arguments:

url - the URL of an HTTP request
headers - headers that should be sent with the request (e.g. [{name: "Authorization", value: "Bearer FOOBARBAZ"}])
query - query string parameters that should be sent with the request (e.g. [{name: "page-number", value: "1"}])
forAll - A JSON Path expression. For every element, returned by this expression executed against current context value, a separate HTTP request would be sent. An elem placeholder scope may be used in combination with this argument.

url, headers and query may contain the placeholders which are described below. value directive may be used in combination with httpGet - it will extract part of the relevant JSON out of the HTTP response.

`@includeSchema`

directive @includeSchema(
  name: String!
  url: String!
  headers: [Header!],
  delegateHeaders: [String!] 
  query: [QueryParam!]
  oauth: OAuthClientCredentials) repeatable on SCHEMA

input OAuthClientCredentials {
  url: String!
  clientId: String!
  clientSecret: String!
  scopes: [String!]!
}

Includes external GraphQL schema (based on GraphQL endpoint URL)

`@includeFields`

directive @includeFields(
  "the name of the schema included with @includeGraphQL"
  schema: String!
  
  "the name of the type from the external schema" 
  type: String!
  
  "optional list of fields to include (of not provided, all fields are included)"    
  fields: [String!]
  
  "optional list of fields to exclude"    
  excludes: [String!]) repeatable on OBJECT

Adds fields loaded from the external GraphQL schema.

`@fake`

directive @fake(
  expr: String, 
  type: FakeType, 
  min: Int, 
  max: Int, 
  past: Boolean, 
  future: Boolean) on FIELD_DEFINITION

Provides fake data. If the field returns a list, it's size can be customized with min/max. If the field returns a DateTime, then past/future would be used.

The fake data type can be customized with an expression expr. An expression has following structure:

#{category.name 'arg1','arg2'}

Here is a small example:

type Info {
  createAt: DateTime
}

type Query {
  name: String! @fake(expr: "name.fullName")
  address: String! @fake(expr: "#{address.fullAddress} - #{numerify 'SOME######'}")
  info: Info! @fake
}

Applies both a numerify(String) and a letterify(String) over the incoming string.
letterify(letterString: String, isUpper: Boolean)

Returns a string with the '?' characters in the parameter replaced with random alphabetic characters. For example, the string "12??34" could be replaced with a string like "12AB34".
letterify(letterString: String)

`@fakeConfig`

directive @fakeConfig(locale: String, seed: Int) on SCHEMA

Customize fake data generation

`@const`

directive @const(value: Any!) on FIELD_DEFINITION | SCHEMA

Provides a way to resolve a field with a constant value. value can be any valid GraphQL input value. It would be treated as a JSON value.

`@jsonConst`

directive @jsonConst(value: String!) on FIELD_DEFINITION | SCHEMA

Provides a way to resolve a field with a constant value. value should be a valid JSON value.

`@arg`

directive @arg(name: String!) on FIELD_DEFINITION

Provides a way to resolve a field with value of one of its arguments.

`@value`

directive @value(name: String, path: String) on FIELD_DEFINITION

Extracts a value(s) from the context object. It supports following extractors via arguments (only one can be used):

name - Extracts a named property value from a context JSON object
path - A JSON Path expression. It would be executed against current context JSON value.

`@context`

directive @context(name: String, path: String) on FIELD_DEFINITION

Extracts a value(s) from the context object defined on the schema level. It supports following extractors via arguments (only one can be used):

name - Extracts a named property value from a JSON object
path - A JSON Path expression. It would be executed against current context JSON value, which is defined at the schema level.

Placeholders

Placeholders may be used in some the directive arguments (inside of the strings) and the syntax looks like this:

${value.$.results[0].film}

The placeholder consists of two parts separated by dot (.): the scope (value in this case) and the extractor ($.results[0].film) - a JSON Path extractor in this example). The scope defines a place/value from which you would like extract a value. Following scopes are supported:

arg - field argument
value - a context value
ctx - a context value which is defined on a schema level
elem - an extracted element that comes from the forAll argument
env - an environment variable

The extractor can be either a string (the name of the property) or a JSON Path expression.
