Mutation ДЄll that without any extra code or configuration. You can run PostGraphile with the following command: By default Postgres uses the implicit public schema (and you can with Graphile too), but by definining our own, we can explicitly expose only what we want to to our api. The only thing really out of the ordinary here is the schema. For the most part this is the exact kind of thing you would create for use with an ORM.

IвЂ™m using UUIDs here because IвЂ™m cool, but auto increment (type SERIAL in Postgres) ids would work find too. Otherwise youвЂ™ll need to use the command line. Postico gives you a UI to create a new database, and you can execute raw queries in the вЂњSQL QueryвЂќ view. If youвЂ™re on a mac, I recomment installing Postgres.app and Postico. post, body text NOT NULL, created_at timestamp NOT NULL DEFAULT now () ) comment ( id uuid PRIMARY KEY DEFAULT uuid_generate_v4 (), post_id uuid REFERENCES app. user, title text NOT NULL, body text, created_at timestamp NOT NULL DEFAULT now () ) CREATE TABLE app. post ( id uuid PRIMARY KEY DEFAULT uuid_generate_v4 (), user_id uuid REFERENCES app. user ( id uuid PRIMARY KEY DEFAULT uuid_generate_v4 (), first_name text NOT NULL, last_name text NOT NULL, created_at timestamp NOT NULL DEFAULT now () ) CREATE TABLE app. As long as you mark foreign keys as referencing other tables, Graphile will connect them.ДЇor example, letвЂ™s create a blog database with users, posts and comments:Д¬REATE EXTENSION 'uuid-ossp' CREATE SCHEMA app CREATE TABLE app. To get started, all you need is a Postgres database and a few tables. Even a good ORM will use several queries when prefetching relations. Additionally, becuase itвЂ™s able to combine the entire API request into a single query, it avoids the typical N+1 query problem that most ORMs suffer from. It is able to be extended and merged with other GraphQL APIs and extentions, or completely replaced with an ORM that reuses the same schema. Postgres does all the things, and Graphile takes advantage of many built in features, many of which you would be using with a traditional ORM, along with some that you probably should be using. Graphile is a tool that generates a fully working GraphQL API almost entirely from a Postgres database. And thereвЂ™s a lot of boilerplate in the middle to make it all work properly.Д®nter PostGraphile. Now, you may be writting really advanced backend api logic with custom algorithms and lasers, but the apis I write mostly take data from a database (almost always PostgreSQL) and return it to the client as JSON. But lately, IвЂ™ve been asking my apis an uncomfortable question: If what you are building is an app (either web or native), it probably involves writting some kind of api layer. I always say that a working prototype is worth a thousand meetings. But even estabilished companies can benefit from getting a working prototype or beta out. This is espeically true for side projects and startups where you have limited time and runway to get an idea fleshed out and figure out what works and what doesnвЂ™t.

One of the most important aspects to software development is rapid prototyping.

ItвЂ™s a note for me, I hope it could help other people too.Rapid API development using PostgreSQL, GraphQL, and PostGraphile I posted only a few examples here, about what seems the most common use cases to me. Querying on JSONB objects is almost as simple as classic SQL queries.

UPDATE users SET metadata = metadata - 'country' Final note The operator - removes a key from an object. SELECT * FROM users WHERE metadata '' 10.

For this case you may need to add a GIN index on metadata column. This operator can compare partial JSON strings against a JSONB column. You can query with the operator on metadata. Select items by the value of a first level attribute (#1 way)
