Config File

chant uses a chant.config.ts file at the project root for configuration.

Minimal Config

chant.config.ts

export default {
  lexicons: ["aws"],
};

Full Config

chant.config.ts

export default {
  lexicons: ["aws"],

  lint: {
    extends: ["@intentius/chant/lint/presets/strict"],

    rules: {
      "EVL001": "error",
      "COR002": "warning",
      "COR009": "off",
    },

    overrides: [
      {
        files: ["src/legacy/**/*.ts"],
        rules: {
          "EVL001": "warning",
          "COR005": "off",
        },
      },
    ],

    plugins: ["./lint-rules/org-standards.ts"],
  },
};

Fields

lexicons

An array of lexicon names the project uses.

ownership

Opt-in cloud-side ownership marking. When stack is set, the serializer stamps a chant ownership marker carrying this stack (and optional env) identity onto every supported resource at synthesis time:

ownership: {
  stack: "billing",   // stamped onto every resource (enables marking)
  env: "prod",        // optional environment identity
  // enabled: false,  // set to disable without removing the block
}

The marker is the record that later lets delete be precise without an authoritative state file — ownership lives on the cloud resource, not in a file chant has to host or lock. It is stamped into each target’s native metadata channel:

Channel	Targets	Keys
Labels	Kubernetes, GCP (Config Connector)	app.kubernetes.io/managed-by=chant, chant.intentius.io/stack, chant.intentius.io/env
Tags	AWS	chant:managed-by=chant, chant:stack, chant:env
Tags	Azure	chant-managed-by=chant, chant-stack, chant-env

The marker carries stack identity, not just managed=true, so one stack never mistakes another’s resources for its own. Ownership means “carries chant’s marker”, not “carries only chant’s marker” — co-stamping with other tools (ArgoCD, Terraform) is fine, and explicit per-resource tags/labels win on key collisions. Walk-away cost stays zero: these are standard tags/labels, nothing proprietary.

lint.extends

An array of preset configuration paths to inherit from:

extends: ["@intentius/chant/lint/presets/strict"]

lint.rules

A map of rule ID to severity or [severity, options] tuple:

rules: {
  "EVL001": "error",
  "COR009": ["warning", { max: 12 }],
}

lint.overrides

File-specific rule overrides using glob patterns:

overrides: [
  {
    files: ["src/legacy/**/*.ts"],
    rules: { "EVL001": "warning" },
  },
]

lint.plugins

An array of plugin paths to load custom lint rules:

plugins: ["./lint-rules/org-standards.ts"]

Config Resolution

1. Load chant.config.ts from the project root
2. Resolve and merge all extends presets (in order)
3. Apply local rules on top
4. Load plugins
5. At lint time, apply overrides to matching files
