Top 23 Codegen Open-Source Projects

• tabby

  26 17,420 9.9 Rust

  Self-hosted AI coding assistant

  

Project mention: 17 Best Developer Productivity Tools to Try | dev.to | 2024-05-10

Two other tools emerging in this category are SuperMaven and TabbyML, both use fast and secure LLM for code completion and recommendations.

• wire

  30 12,368 2.7 Go

  Compile-time Dependency Injection for Go

  

Project mention: Borgo is a statically typed language that compiles to Go | news.ycombinator.com | 2024-04-30

code generation is a mostly disjoint topic from DI. Granted, some solutions like https://github.com/google/wire use code generation, but you're exactly right about their pitfalls. If your dev environment doesn't have good support for generated code, it is a nightmare. If you can goto-definition the generated code, then it is suddenly feasible, but perhaps still a bad choice.

• InfluxDB

  www.influxdata.com featured

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• graphql-code-generator

  69 10,636 9.1 TypeScript

  A tool for generating code based on a GraphQL schema and GraphQL operations (query/mutation/subscription), with flexible support for custom plugins.

Project mention: Integrating GraphQL Codegen with Storyblok: Step-by-Step Guide | dev.to | 2024-01-15

The @graphql-codegen library is a bridge between your GraphQL schema and the actual code you write. It automates the generation of boilerplate code, ensuring that your data fetching layer is always up to date with your content structure.

• gqlgen

  43 9,635 9.3 Go

  go generate based graphql server library

  

Project mention: Who moved my error codes? Adding error types to your GoLang GraphQL Server | dev.to | 2023-06-25

GraphQL’s spec, as it turns out, does not specify how servers should handle internal errors at all, leaving it entirely to the choice of the frameworks’ creators. Take for example our GoLang GraphQL framework of choice - gqlgen. It makes no distinction between intentional and unexpected errors: all errors are returned as-is to the client within the error message. Internal errors, which often contain sensitive information like network details and internal URIs, would leak to clients easily if not caught manually by the programmer.

• Insanity

  12 7,544 9.2 Swift

  Meta-programming for Swift, stop writing boilerplate code.

Project mention: Insanity VS SpeziTemplateApplication - a user suggested alternative | libhunt.com/r/Sourcery | 2023-11-18

• NSwag

  40 6,503 8.7 C#

  The Swagger/OpenAPI toolchain for .NET, ASP.NET Core and TypeScript.

Project mention: TypeSpec: A New Language for API-Centric Development | news.ycombinator.com | 2024-04-29

https://github.com/RicoSuter/NSwag

There is no need to be facetious solutions like these exist for many platforms and ecosystems out there.

With best regards.

• rust-bindgen

  50 4,131 9.0 Rust

  Automatically generates Rust FFI bindings to C (and some C++) libraries.

• zydis

  4 3,201 7.6 C

  Fast and lightweight x86/x86-64 disassembler and code generation library

  

Project mention: Exploring x86-64 Instruction Encoding | news.ycombinator.com | 2024-01-07

• openapi-typescript-codegen

  9 2,685 9.6 TypeScript

  NodeJS library that generates Typescript or Javascript clients based on the OpenAPI specification

Project mention: Django 5.0 Is Released | news.ycombinator.com | 2023-12-04

I’d also add that if you use Typescript with an OpenAPI client generator (https://github.com/ferdikoomen/openapi-typescript-codegen) it can immensely alleviate some of the biggest pain points of seperate backend and front-end. It always used to be a major pain in the ass with the amount of overhead an API change would incur - updating documentation, postman, constant communication between backend and front-end devs, etc. Now I just npm run generate, I see new API changes in my Git client and Typescript errors for code that needs updating.

Also, using a library like Tanstack Query or Rdtk Query can almost completely eliminate manual state management, and kinda makes the whole development experience feel almost like SSR.

• orval

  20 2,297 9.6 TypeScript

  orval is able to generate client with appropriate type-signatures (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification, either in yaml or json formats. 🍺

Project mention: HonoJS: Small, simple, and ultrafast web framework for the Edges | news.ycombinator.com | 2024-04-15

In cases where the client needs to stay separate, we have had a good experience with Orval[1] to generate a fully-typed @tanstack/query client from our OpenAPI spec.

• inkwell

  16 2,158 8.2 Rust

  It's a New Kind of Wrapper for Exposing LLVM (Safely)

Project mention: Compiler Optimization Learning Suggestions | /r/Compilers | 2023-08-04

Secondly, I have learned about LLVM, and I have learned about the Inkwell library on Rust (It's a New Kind of Wrapper for Exposing LLVM (Safely)). Has anyone used this library before? Is this a good practice? Is it suitable for my compiler? Can I write some optimization passes of my own using this library?

• moq

  16 1,771 3.6 Go

  Interface mocking tool for go generate (by matryer)

Project mention: vektra/mockery has fully released the "packages" feature! This blog explains what it is and how it works. | /r/golang | 2023-07-11

• astring

  1 1,141 4.3 JavaScript

  🌳 Tiny and fast JavaScript code generator from an ESTree-compliant AST.

• ogen

  10 1,095 9.5 Go

  OpenAPI v3 code generator for go

  

Project mention: I write HTTP services in Go after 13 years (Mat Ryer, 2024) | news.ycombinator.com | 2024-02-09

https://github.com/ogen-go/ogen

Write openapi definition, it'll do routing, definition of structs, validation of JSON schemas, etc.

All I need to do is implement the service.

Validating an integer range for a querystring parameter is just too boring. And too easy to mistype when writing it manually.

Anyways, so far only been playing, so haven't found the bad parts yet.

• genqlient

  6 985 6.7 Go

  a truly type-safe Go GraphQL client

  

Project mention: GitHub - Warashi/compgen: Compgen is a gqlgen plugin designed to simplify the generation of ComplexityRoot for gqlgen. | /r/golang | 2023-06-01

The client support in particular is currently very awkward. For instance, there's this discussion around Hasura in the Khan/genqlient repo: https://github.com/Khan/genqlient/issues/272

• vtprotobuf

  3 819 7.9 Go

  A Protocol Buffers compiler that generates optimized marshaling & unmarshaling Go code for ProtoBuf APIv2

  

• flapigen-rs

  4 756 5.6 Rust

  Tool for connecting programs or libraries written in Rust with other languages

• generator

  6 728 9.1 JavaScript

  Use your AsyncAPI definition to generate literally anything. Markdown documentation, Node.js code, HTML documentation, anything!

  

Project mention: AsyncAPI: a practical look | dev.to | 2024-05-03

The "most official" AsyncAPI generator linked from the AsyncAPI site will follow the references in the "allOf" structure to generate the subclasses of the Pet class. But it will ignore the "discriminator" logic and actually fail because it does know what to do with the "petType" attribute repeated in the derived types (e.g. StickInsect).
