caffeine_lang

The pure compiler core for the Caffeine DSL. It generates reliability SLOs (Terraform for Datadog) from service expectation definitions. The vendor abstraction (Vendor enum, Platform registry, multi-vendor compiler dispatch) is in place so additional vendors can be added by registering a new Platform and generator module.

Usage

# gleam.toml

let result = compiler.compile_from_strings(blueprints, expectations, output_path)

In the browser

import { compile_from_strings } from "./caffeine-browser.js";
const result = compile_from_strings(blueprintsJson, expectationsJson, "org/team/service.json");
