Informations about the package lighthouse-utils
Lighthouse Utils (no longer maintained)
This package can generate queries for the Lighthouse GraphQL library. This is not a standalone package, so Lighthouse is listed as a dependency.
To generate queries, all you need to do is define a couple of GraphQL Types and run the generate command. Scroll down to 'Schema' to learn more.
We also include a couple of Directives and Scalar types. More about that later on.
Installation
Install via composer
Alternatively, you can try the example installation below.

Usage
This package uses Laravel Auto Discovery to register itself with your application.
It exposes a GraphQL interface interface on the /graphql
route.
To get started, run the following command in your Laravel application:
A config file will be generated: config/lighthouse.php
. You can change these values if you want.
Schema generation
Define your GraphQL schema by adding Types, Queries and Mutations in app/GraphQL/Types
, app/GraphQL/Queries
and app/GraphQL/Mutations
directories.
If you want to change these paths, publish the config file for this package and change the paths there.
Currently this package only supports custom Types, Queries and Mutations are ignored. You can define your custom types and run the command below to auto-generate queries and mutations for those types. In the future it will be possible to add custom queries and mutations to the above directories. These will then also be used in the generated schema.
For more information on schemas and basic Lighthouse usage, check the Lighthouse docs
To generate your schema.graphql
file, run the following command:
The schema will be generated to the path as defined in the Lighthouse config, lighthouse.schema.register
Custom Queries and Mutations
It might happen that you need a custom query or mutation beside the generated schema. In this package you have the ability to add custom queries and mutations by creating .graphql
files in the default directories
app/GraphQL/Queries
and app/GraphQL/Mutations
(These directories are adjustable by editing the config/lighthouse.php
file)
Take for example a custom query to retrieve an instance of a model:
This query will be parsed after running the schema generation command and will be added to the Query section of the schema.graphql
Scalar types
Currently two scalar types are included. More about scalar type usage can be found here.
Date
A date string with format Y-m-d. Example: "2018-01-01"
scalar Date @scalar(class: "DeInternetJongens\\LighthouseUtils\\Schema\\Scalars\\Date")
DateTimeTZ
A date string with format Y-m-d H:i:s+P. Example: "2018-01-01 13:00:00+00:00"
scalar DateTimeTz @scalar(class: "DeInternetJongens\\LighthouseUtils\\Schema\\Scalars\\DateTimeTz")
PostalCodeNl
A postal code as valid for The Netherlands, format 1111aa. Example: "7311SZ"
An RFC 5321 compliant e-mail
FullTextSearch
Indicates that a field searches through multiple fields.
To use this scalar, you need to add a scope on your model scopeFullTextSearch
. Example:
In the scope you can basically define whatever kind of query you want.
Directives
To run more advanced queries, a couple of directives are included. These are automatically registered with Lighthouse, so you can use them at your own discretion.
Currently these directives are included:
- contains
- ends_with
- gte
- gt
- lte
- lt
- in (comma seperated string)
- not_contains
- not_ends_with
- not
- not_in (comma seperated string)
- not_starts_with
- starts_with
- fullTextSearch
Migrations
This package stores the generated schema in the database, so the schema is available outside the schema.graphql
and can be used to sync permission.
Publish the migration and migrate the database.
Authorization
To protect your queries and migrations from unauthorized users, you can enable the Authorization feature. To enable authorization, make sure you have published the config for this package and add the following line to your .env file:
LIGHTHOUSE_UTILS_AUTHORIZATION=true
When a schema is generated the event DeInternetJongens\LighthouseUtils\Events\GraphQLSchemaGenerated
will be fired.
In your application you can listen for this event to sync the generated permissions with your application.
The event has a schema
variable with the generated schema.
The generated queries and their corresponding permissions will also be persisted to your database to the graphql_schema
table.
An Eloquent model for this table is included with this package.
