API
The project is an ES6 module. Simply import the module:
import OpenSCAD from "./openscad.js";
// OPTIONAL: add fonts to the FS
import { addFonts } from "./openscad.fonts.js";
// OPTIONAL: add MCAD liibrary to the FS
import { addMCAD } from "./openscad.mcad.js";
// Instantiate the application
const instance = await OpenSCAD();
// OPTIONAL: add fonts to the FS
addFonts(instance);
// OPTIONAL: add MCAD liibrary to the FS
addMCAD(instance);
// Write a file to the filesystem
instance.FS.writeFile("/input.scad", `cube(10);`);
// Run OpenSCAD with the arguments "/input.scad -o cube.stl"
instance.callMain(["/input.scad", "-o", "cube.stl"]);
// Read the data from cube.stl
const output = instance.FS.readFile("/cube.stl");For more information on reading and writing files check out the Emscripten File System API.
