Graphweaver is a GraphQL Gateway that can connect many data sources together to create an API. It can be used to create a headless CMS, an API Gateway, or used as a Backend for mobile apps.

Why?

We consistently find that everyone has lots of sources of truth. You know, CRM holding customer data, accounting systems handling invoices, and more scattered across different SaaS platforms and databases? It's a real pain to sync it all up!

In the past we used to copy data from everywhere to the DB, but that always breaks at some point.

Well, after years of grappling with this issue, we wanted a way to easily build a single GraphQL API in front of all those sources. An API that allows you to execute queries that even span across datasources (give me DB records where customer in CRM name is "Bob"), and also allows you to administer your data all from one place.

That's why we built Graphweaver. We've been using it on our projects for about a year now and think you'll love it too!

Features

๐Ÿ“ Code-first GraphQL API: Save time and code efficiently with our code-first approach. ๐Ÿš€ Built for Node in Typescript: The power of Typescript combined with the flexibility of Node.js. ๐Ÿ”— Connect to Multiple Datasources: Seamlessly integrate Postgres, MySql, Sqlite, REST, and more. ๐ŸŽฏ Instant GraphQL API: Get your API up and running quickly with automatic queries and mutations. ๐Ÿ”„ One Command Import: Easily import an existing database with a simple command-line tool.

grappa features and specs

  • Expressive Assertions
    Grappa provides a rich set of expressive assertions which allow for writing readable and concise test cases.
  • Chainable Syntax
    The library supports a chainable syntax that can improve the readability and maintainability of test assertions.
  • Integration
    Grappa can be integrated with multiple testing frameworks, such as Pytest, which can make it easier to incorporate into existing test suites.
  • Extensibility
    The framework supports custom matchers, allowing developers to extend the library's functionality tailored to their specific needs.

Possible disadvantages of grappa

  • Learning Curve
    For developers new to the library, there may be a learning curve associated with understanding the syntax and capabilities of Grappa.
  • Documentation
    Depending on the state of the project, the documentation may not be comprehensive, potentially making it challenging for new users to learn.
  • Community Support
    As a niche library, Grappa might not have as large a community or support as some more widely used testing frameworks.
  • Maintenance
    Open-source projects can sometimes experience slower development and updates, which could impact long-term usability if the project becomes less actively maintained.

Graphweaver features and specs

  • Integration
    Graphweaver allows for the integration of multiple data sources, providing a unified view and ease of data management.
  • Efficiency
    It enhances the efficiency of data retrieval by using GraphQL, which minimizes data over-fetching.
  • Flexibility
    Graphweaver supports flexible query structures, which can be tailored to specific data needs and requirements.
  • Developer Experience
    Provides a developer-friendly experience with comprehensive documentation and tools to streamline the development process.

Possible disadvantages of Graphweaver

  • Complexity
    The initial setup and configuration can be complex, especially for developers who are not familiar with GraphQL or integrating diverse data sources.
  • Learning Curve
    There might be a steep learning curve for new users who are not accustomed to using GraphQL or related technologies.
  • Resource Intensive
    Integrating many data sources might demand higher computational resources, which could increase operational costs.

Analysis of grappa

Overall verdict

  • Grappa is a solid, mature parsing library for the JVM that lets developers build parsers directly in Java using a fluent, PEG-based (Parsing Expression Grammar) approach without needing a separate grammar file or code generation step.

Why this product is good

  • Uses Parsing Expression Grammars (PEG), which are unambiguous and easier to reason about than traditional context-free grammars
  • Grammars are written in pure Java as a fluent DSL, so there's no external grammar file or code-generation build step
  • Integrates naturally into existing Java/JVM projects and tooling
  • Supports parser actions, error recovery, and value stack manipulation for building ASTs
  • Successor to the popular Parboiled library, benefiting from lessons learned in that project
  • Open source and hostable/inspectable directly on GitHub

Recommended for

  • Java and JVM developers who want to build parsers without learning a separate grammar language
  • Projects needing custom domain-specific languages (DSLs) or configuration formats
  • Developers who prefer PEG semantics over ambiguous CFG-based tools like ANTLR
  • Teams that want parser logic kept inline in their codebase rather than generated
  • Prototyping and small-to-medium parsing tasks where fluent Java code is convenient

  • Getting started creating a web app with multiple data sources? Graphweaver!
    Weโ€™re a small dev team based in Sydney and in between client projects weโ€™ve been working on our own open-source tool, Graphweaver. Graphweaver allows you to combine multiple data sources (Databases, Rest APIs, Saas platforms) and expose a single GraphQL API. Itโ€™s a bit like Hasura or Step Zen but with more of a code-first flexibility. It can take your database and with a single import command, generate your code... Source: almost 3 years ago
