djt-codegen

1.0.1 verified Fri May 01 auth: no javascript

A templated code generation tool for the Dart-to-JS-Transpiler (DJT) ecosystem. Current stable version 1.0.1, released occasionally. It generates JavaScript and TypeScript declaration files from a schema definition, targeting DJT transpilation workflows. Differentiates by providing a simple CLI for schema-to-output transformation with DTS support.

Common errors

error Error: Cannot find module 'djt-codegen' ↓

cause Package not installed or missing from node_modules.

fix

Run 'yarn add djt-codegen' or 'npm install djt-codegen'.

error SyntaxError: Unexpected token 'export' ↓

cause Using CommonJS require with an ESM-only package.

fix

Use import syntax or update Node to version that supports ESM.

Warnings

gotcha The -dts flag generates TypeScript definitions but may not cover all schema features. ↓

fix Manually verify generated DTS files for completeness.

gotcha Schema file must be valid JavaScript exporting a schema object; JSON files not supported. ↓

fix Ensure schema file uses module.exports = { ... } syntax.

Install

npm install djt-codegen

yarn add djt-codegen

pnpm add djt-codegen

Imports

generate
wrong
```
const generate = require('djt-codegen').generate
```
correct
```
import { generate } from 'djt-codegen'
```
Package is ESM-only; CommonJS require may fail depending on Node version.

default

wrong

const djtCodegen = require('djt-codegen')

correct

import djtCodegen from 'djt-codegen'

Default export is not documented; prefer named exports.

CodegenOptions
```
import { CodegenOptions } from 'djt-codegen'
```
TypeScript type (if exists); check package types.

Quickstart

Shows CLI usage with schema input, JS output, and DTS generation; also demonstrates programmatic API if available.

// Run via CLI (recommended):
// yarn djt-codegen -s ./schema.js -o ./lib.js -dts ./lib.d.ts

// Or programmatically (if package exports API):
import { generate } from 'djt-codegen';
const fs = require('fs');
const schema = JSON.parse(fs.readFileSync('./schema.json', 'utf8'));
generate({ schema, output: './lib.js', dts: './lib.d.ts' });
