factorio-data

JavaScript tooling for turning Wube's Factorio Lua prototype data into typed JSON/TypeScript artifacts.

The first supported artifact is recipe data. The extractor executes the Wube data stage files with a small Lua harness, then normalizes every recipe prototype into JSON and builds an index of craftable products. Recipe, ingredient, result, and craftable product entries include both game prototype icon paths where available and best-effort Factorio Wiki image/page URLs. Raw resource prototypes are also indexed with the planets where their map generation settings expose them.

Build recipe data

This project expects lua to be available on PATH.

bun install
bun run build:recipes

Outputs:

• generated/recipes.json
• generated/recipes.ts

Library usage

import { extractRecipes, writeRecipeArtifacts } from "factorio-data";

const recipeData = await extractRecipes();
const ironPlateRecipes = recipeData.recipesByProduct["item:iron-plate"].recipes;
const ironPlateIcon = recipeData.recipesByProduct["item:iron-plate"].wikiIconUrl;
const ironOrePlanets = recipeData.resourcesByProduct["item:iron-ore"].planets;
const coalAvailability = recipeData.resources.coal.planets;

await writeRecipeArtifacts({ outDir: "generated" });

Validate Wiki URLs

bun run check:wiki-urls

The checker writes invalid URL details, including every recipe/product reference path, to generated/invalid-wiki-urls.json.
