Template Engine Variables

The Boilerplate comes shipped with a Zero-Dep Template Engine that rapidly scaffolds Domain folders, routes, CRUD actions, schemas, and test blocks whenever you run bun gen:domain <name>.

The source templates live in src/templates/domain/.

Built-In Wildcards

When the bundler parses a text-file template (like get-by-id.ts or routes.ts), it replaces specific hard-coded wildcards with the CLI argument you submitted string-manipulated to the specific style.

If you extend or customize the core scaffolding templates to fit your business logic, you can safely use these wildcards:

Wildcard String	Target Format	CLI Output Example for bun gen:domain process	Use Case
__name__	Strict Literal	process	For directory names, path parameters (/process/:id), general lowercased references, and Cache mapping tags.
__Capitalized__	Capitalized	Process	Essential for naming TypeScript classes, Fastify Route function definitions (e.g. export default async function routesProcess(server)), and schema names.

Example Usage inside a Template

// src/templates/domain/actions/delete-entity.ts

// The compiler sees:
import { tag } from "@infrastructure/repositories/references";
import __name__ from "../entity";

// And outputs (if gen:domain user):
import { tag } from "@infrastructure/repositories/references";
import user from "../entity";
