Readme
reflectapi is a library and a toolkit for writing web API services in Rust and generating compatible clients, delivering great development experience and efficiency.
Features
Code-first definition of services with API over HTTP
100% compatible type-safe and extensible clients delivering same simplicity and intent of the server API
Multi-language client generation :
TypeScript - stable
Rust - stable
Python - experimental
Documentation rendering using Redoc tool
Web framework agnostic with plugable Axum support included, other frameworks are possible
Full support for all serde attributes
Full enablement for all Rust types , including standard library, common popular crates and adding support for 3rd party and custom types is straightforward

Development notes
Building and running
Ensure that you have prettier and rustfmt available in your PATH to format generated code.
To run the demo server:
cargo run -- bin reflectapi-demo
To generate client in Typescript for demo server:
cargo run -- bin reflectapi -- codegen --language typescript --schema reflectapi-demo/reflectapi.json --output reflectapi-demo/clients/typescript
To run the Typescript generated client. Note: requires the demo server running
cd reflectapi-demo/clients/typescript/
npm install
npm run start
To generate client in Rust for demo server:
cargo run -- bin reflectapi -- codegen --language rust --schema reflectapi-demo/reflectapi.json --output reflectapi-demo/clients/rust/generated/src/
To run the Rust generated client. Note: requires the demo server running
cd reflectapi-demo/clients/rust/
cargo run -- all-features
To generate client in Python for demo server:
cargo run -- bin reflectapi -- codegen --language python --schema reflectapi-demo/reflectapi.json --output reflectapi-demo/clients/python
Updating Snapshots
This project uses insta for snapshot testing to ensure code generation output is correct and stable. When tests fail due to snapshot mismatches:
Review the changes first to ensure they are expected
Update snapshots using one of these commands:
# Interactive review (recommended)
cargo insta review
# Auto-accept all changes (use with caution)
cargo insta accept
Re-run tests to verify they pass:
cargo test
Building Documentation
# Install required tools (one-time setup)
cargo install mdbook mdbook-keeper
# Build documentation
cd docs
mdbook build
# Serve documentation locally
mdbook serve # Opens at http://localhost:3000
# Note: mdbook-keeper automatically runs doctests during build
# The build command both generates HTML and tests code examples
