Lura
Lura is a free Go library for developers building a stateless API gateway or proxy for cloud-native and on-premises setups.
What Lura is
Lura is a free Go library for developers building a stateless API gateway or proxy for cloud-native and on-premises setups. It combines backend sources behind endpoints, so a client can request data from multiple services through one endpoint and receive selected fields. Its proxy can group, wrap, transform, and shrink responses, and includes an EntityFormatter for response manipulation. Building blocks include configuration, router, and proxy packages, with helpers for encoding, logging, and service discovery. Documented middleware covers balancing, concurrent requests, request and response logging, response merging, and HTTP URL patterns. Lura supports HTTP(S); the documentation describes adapters for transports such as Thrift, gRPC, AMQP, and NATS as possible additions. The router layer can also be extended with other HTTP routers, frameworks, or middleware. Lura is compiled from source, which requires Go. KrakenD Community Edition is identified as an implementation using Lura. The project is hosted by The Linux Foundation and points users to its issue tracker and Slack channel for communication.
Good
- Free, open-source Go library
- Combines multiple backend sources behind one endpoint
- Includes middleware for balancing and response merging
- Router layer can be extended
- Supports HTTP(S)
Watch out
- Requires Go to compile
- Provided as a library to include in an application
- Other transport protocols require added adapters
Who it suits
Lura is for developers who want to build an API gateway or proxy inside their own Go application. It fits teams that can compile and self-host a Go library.
Verdict
Lura provides gateway building blocks and response processing for developers working in Go. It supports HTTP(S) directly, while other transports require adapters.
