kvapp

A fully built-out, production-ready skeleton of a Rust microservice API.

The example microservice: A simple database service for NoSQL key/value database.

Motivation

Create a production-ready clone-and-go Rust template for a multi-threaded HTTP REST microservice, that is fully wired for familiar production artifacts such as Github Actions testing and docker container builds.

Features

Uses the latest actix, tokio libraries
Multi-threaded
Includes end-to-end integration test framework
HTTP request logging
Configuration via JSON config file, or CLI
Server Info and Health Check API meta-endpoints
Docker-ized
Integrated with GitHub CI

Using kvapp

Standard rust cargo binary setup:

$ cargo build
$ cargo run

Server configuration

A JSON configuration file is required, to specify database. Command line options are also available.

Configuration file

See example-cfg-kvapp.json for an example configuration file.

database section

The database section contains an object which describes a database to configure and expose via this API service.

Specify a short name, local path and other db attributes to configure the database.

name: Short URI-compatible name, exposed via API at database name.
path: Local filesystem path to sled db directory.

Command line help

Also, limited options are available at the command line. Run --help to view available options:

$ cargo run -- --help

Testing

End-to-end integration testing is performed in the usual cargo way:

$ cargo test

Server API

The microservice API is described in the kvapp API documentation.
