GraphJin Instant GraphQL API
GraphJin gives you an instant secure and fast GraphQL API without code. GraphQL is automagically compiled into an efficient SQL query. Use either as a library or a standalone service. Build your backend APIs 100X faster.
Use in your own code
You can use GraphJin as a library within your own code. The core package exposes just the GraphJin compiler. The Go docs are filled with examples on how to use GraphJin within your own apps as a sort of alternative to using ORM packages. GraphJin allows you to use GraphQL and the full power of GraphJin to access your data instead of a limiting ORM.
go get github.com/dosco/graphjin/core
package main
import (
"context"
"fmt"
"log"
"github.com/dosco/graphjin/core"
"github.com/jackc/pgx/v4/pgxpool"
)
func main() {
db, err := pgxpool.Connect(context.Background(), "postgres://postgres:@localhost:5432/example_db")
if err != nil {
log.Fatal(err)
}
sg, err := core.NewGraphJin(nil, db)
if err != nil {
log.Fatal(err)
}
query := `
query {
posts {
id
title
}
}`
ctx := context.Background()
ctx = context.WithValue(ctx, core.UserIDKey, 1)
res, err := sg.GraphQL(ctx, query, nil, nil)
if err != nil {
log.Fatal(err)
}
fmt.Println(string(res.Data))
}

About GraphJin
After working on several products through my career I found that we spend way too much time on building API backends. Most APIs also need constant updating, and this costs time and money.
It's always the same thing, figure out what the UI needs then build an endpoint for it. Most API code involves struggling with an ORM to query a database and mangle the data into a shape that the UI expects to see.
I didn't want to write this code anymore, I wanted the computer to do it. Enter GraphQL, to me it sounded great, but it still required me to write all the same database query code.
Having worked with compilers before I saw this as a compiler problem. Why not build a compiler that converts GraphQL to highly efficient SQL.
This compiler is what sits at the heart of GraphJin, with layers of useful functionality around it like authentication, remote joins, rails integration, database migrations, and everything else needed for you to build production-ready apps with it.
Better APIs Faster!
Lets take for example a simple blog app. You'll probably need the following APIs user management, posts, comments, votes. Each of these areas need apis for listing, creating, updating, deleting. Off the top of my head thats like 12 APIs if not more. This is just for managing things for rendering the blog posts, home page, profile page you probably need many more view apis that fetch a whole bunch of things at the same time. This is a lot and we're still talking something simple like a basic blogging app. All these APIs have to be coded up by someone and then the code maintained, updated, made secure, fast, etc. We are talking weeks to months of work if not more. Also remember your mobile and web developers have to wait around till this is all done.
With GraphJin your web and mobile developers can start building instantly. All they have to do is just build the GraphQL queries they need and GraphJin fetches the data. Nothing to maintain no backend API code, its secure, lighting fast and has tons of useful features like subscriptions, rate limiting, etc built-in. With GraphJin your building APIs in minutes not days.
