Overview

Package core provides an API to include and use the GraphJin compiler with your own code. For detailed documentation visit https://graphjin.com

Example usage: 

package main

import (
	"database/sql"
	"fmt"
	"time"
	"github.com/dosco/graphjin/core"
	_ "github.com/jackc/pgx/v4/stdlib"
)

func main() {
	db, err := sql.Open("pgx", "postgres://postgrs:@localhost:5432/example_db")
	if err != nil {
		log.Fatal(err)
	}

	gj, err := core.NewGraphJin(nil, db)
	if err != nil {
		log.Fatal(err)
	}

	query := `
		query {
			posts {
			id
			title
		}
	}`

	ctx = context.WithValue(ctx, core.UserIDKey, 1)

	res, err := gj.GraphQL(ctx, query, nil)
	if err != nil {
		log.Fatal(err)
	}

}
Example (BlockQueryWithRoles) 
gql := `query {
		users {
			id
			full_name
			email
		}
	}`

conf := newConfig(&core.Config{DBType: dbType, DisableAllowList: true})
conf.RolesQuery = `SELECT * FROM users WHERE id = $user_id`
conf.Roles = []core.Role{{Name: "disabled_user", Match: "disabled = true"}}

err := conf.AddRoleTable("disabled_user", "users", core.Query{Block: true})
if err != nil {
	panic(err)
}

gj, err := core.NewGraphJin(conf, db)
if err != nil {
	panic(err)
}

ctx := context.WithValue(context.Background(), core.UserIDKey, 50)
res, err := gj.GraphQL(ctx, gql, nil, nil)
if err != nil {
	fmt.Println(err)
} else {
	fmt.Println(string(res.Data))
}

Output:

{"users": null}

GraphQL function is called on the GraphJin struct to convert the provided GraphQL query into an SQL query and execute it on the database. In production mode prepared statements are directly used and no query compiling takes places.

In developer mode all names queries are saved into a file `allow.list` and in production mode only queries from this file can be run.

}

Query struct contains access control values for query operations

type ReqConfig 

type ReqConfig struct {
	// Namespace is used to namespace requests within a single instance of GraphJin. For example queries with the same name
	// can exist in allow list in seperate namespaces.

	// APQKey is set when using GraphJin with automatic persisted queries
	APQKey string

	// Pass additional variables complex variables such as functions that return string values.
	Vars map[string]interface{}
}

ReqConfig is used to pass request specific config values to the GraphQLEx and SubscribeEx functions. Dynamic variables can be set here.

type Resolver added in v0.15.56 

type Resolver interface {
	Resolve(ResolverReq) ([]byte, error)
}

Resolver interface is used to create custom resolvers Custom resolvers must return a JSON value to be merged into the response JSON.

Example Redis Resolver: 

type Redis struct {
	Addr string
	client redis.Client
}

func newRedis(v map[string]interface{}) (*Redis, error) {
	re := &Redis{}
	if err := mapstructure.Decode(v, re); err != nil {
		return nil, err
	}
	re.client := redis.NewClient(&redis.Options{
		Addr:     re.Addr,
		Password: "", // no password set
		DB:       0,  // use default DB
	})
	return re, nil
}

func (r *remoteAPI) Resolve(req ResolverReq) ([]byte, error) {
	val, err := rdb.Get(ctx, req.ID).Result()
	if err != nil {
			return err
	}

	return val, nil
}

func main() {
	conf := core.Config{
		Resolvers: []Resolver{
			Name: "cached_profile",
			Type: "redis",
			Table: "users",
			Column: "id",
			Props: []ResolverProps{
				"addr": "localhost:6379",
			},
		},
	}

	gj.conf.SetResolver("redis", func(v ResolverProps) (Resolver, error) {
