PostGraphile VS PostGraphQL

• Automatic API Generation
  PostGraphile automatically generates a GraphQL API from a PostgreSQL database, simplifying the development process by eliminating the need to manually create API endpoints.
• Efficient Performance
  PostGraphile is optimized for performance, offering features like query planning and batching to ensure that it handles large and complex queries efficiently.
• Rapid Prototyping
  The tool enables rapid prototyping by quickly turning a database schema into a working API, which is useful for testing ideas and building MVPs.
• Feature Rich
  PostGraphile supports various advanced features out-of-the-box, such as real-time updates with subscriptions, advanced filtering, and pagination.
• Strong PostgreSQL Integration
  Being specifically designed for PostgreSQL, PostGraphile provides deep integration with PostgreSQL features, making it possible to leverage database functions, views, and security features directly.

Possible disadvantages

• Steep Learning Curve
  While powerful, PostGraphile can be complex to learn, especially for developers unfamiliar with PostgreSQL or GraphQL, due to its extensive configuration options and feature set.
• Limited to PostgreSQL
  PostGraphile is designed to work specifically with PostgreSQL, which means it cannot be used with other databases like MySQL or MongoDB, limiting its applicability in diverse tech stacks.
• Overhead for Simple Applications
  For simple applications, the advanced features and automatic generation can create unnecessary overhead, potentially complicating simple CRUD operations.
• Less Control Over SQL
  Since automatic GraphQL generation is based on the database schema, developers may have less fine-grained control over the SQL queries that are generated, which can be a limitation for highly optimized or specific query requirements.
• Dependency on Database Schema
  Changes in the database schema directly affect the API, which can be a drawback if the schema evolves frequently, requiring more cautious database management to ensure API stability.

• Automatic Schema Generation
  PostGraphQL automatically generates a GraphQL schema based on the structure and relationships within your PostgreSQL database, reducing the need for manual schema definition and maintenance.
• Efficiency
  By leveraging PostgreSQL functions, PostGraphQL can efficiently execute complex queries directly within the database, leading to potentially faster query performance.
• Consistent API
  The tool ensures a consistent and predictable API is generated from the database schema, which can simplify client-side development and integration.
• Support for PostgreSQL Features
  PostGraphQL takes advantage of PostgreSQL's advanced features such as triggers, views, and stored procedures, allowing for rich and powerful API capabilities.

Possible disadvantages

• Complexity with Custom Logic
  Implementing custom business logic can become complex, as it often requires embedding logic within the database using SQL or PL/pgSQL, which may not be as straightforward as writing it in a standalone application server.
• Overhead for Simple Applications
  For simple applications with limited database interactions, PostGraphQL might introduce unnecessary complexity and overhead compared to using a traditional REST API or a simpler GraphQL server.
• Learning Curve
  Developers unfamiliar with PostgreSQL might face a learning curve in leveraging the full capabilities of PostGraphQL, particularly if they're not accustomed to database-centric application design.
• Tight Coupling with Database
  PostGraphQL closely ties the API design to the database schema, which may reduce flexibility in cases where the API design needs to evolve independently of the database structure.

• [Question] What will it take to create an automated graphQL API with Elixir?

  There are tools like Hasura/Haskell, Postgraphile/Node.js or Graphjin/Golang that could generate an automatic graphQL API from a Postgres database. Im new to Elixir and really love it. I wonder if there is anything similar these. I heard... Source: almost 4 years ago

• Best Orm that uses Graphql and Postgres

  If you point is to abstract all the CRUD/GraphQL application, Go isn’t needed. You can go with PostgREST or Postgraphile. Source: almost 4 years ago

• Ask HN: Locally generate GraphQL schema and resolvers from DB

  What do you mean locally? Hasura is OSS, and you can run it locally (you have autogenerated SQL statements) Here you can just use Nhost and its CLI; Alternatives are https://github.com/graphile/postgraphile or dgraph as you mentioned.... - Source: Hacker News / almost 4 years ago

• Supabase (YC S20) raises $80M Series B

  I've personally found Postgraphile to be fantastic. Nicer to use than Hasura and fully OSS: https://github.com/graphile/postgraphile/. - Source: Hacker News / over 4 years ago
