Node.js Bindings

The Node.js binding has a book of its own:

→ dynamic-config for Node.js

npm install dynamic-config-node

import { DynamicConfig, zodValidator } from "dynamic-config-node"
import { z } from "zod"

const Database = z.object({ host: z.string(), port: z.number().default(5432) })

const db = await new DynamicConfig({ key: "db", validate: zodValidator(Database) })
  .file("config.toml")
  .env("APP_")
  .initAndCurrent()
//    ^? { host: string; port: number }

Rust resolves, your schema validates, JavaScript reads a cached object. One prebuilt binary per platform through Node-API, so the same binary serves every Node version the package claims and nothing compiles at install time.

The Node documentation is its own book, on the same site, and links back here for the engine's own behaviour.
