langium-zod / generate

Function: generate()

function generate(opts): Promise<void>;

Defined in: generate.ts:162

Programmatic entry point for the langium-zod generate command.

Loads langium-config.json from opts.langiumConfigPath, resolves the grammar file path, parses the grammar with Langium services (including eager import loading so cross-file references link correctly), then calls generateZodSchemas with the merged configuration. Prints a success message to stdout when generation completes.

Parameters

Parameter	Type	Description
opts	GenerateOptions	GenerateOptions specifying the langium config path and optional pre-merged generator config.

Returns

Promise<void>

Throws

Error when the langium-config.json or grammar file cannot be found, or when the config defines no languages.

Example

import { generate } from 'langium-zod';
import { resolve } from 'node:path';

await generate({
  langiumConfigPath: resolve(process.cwd(), 'langium-config.json'),
  config: {
    outputPath: 'src/generated/zod-schemas.ts',
    stripInternals: true,
  },
});
// Prints: ✓ Generated Zod schemas → src/generated/zod-schemas.ts
