Hello, World! | OpenCascade.js

~~cnpm install opencascade.js~~

~~cnpm install vite-plugin-wasm --save-dev~~

当你不知道文件写哪的时候trae还是有点用的

‘’‘

import { defineConfig } from 'vite';
import wasm from 'vite-plugin-wasm';
import rollupWasm from '@rollup/plugin-wasm';export default defineConfig({plugins: [wasm(),  // Handles Wasm ESM integrationrollupWasm()  // Provides Rollup-level Wasm support],// Optional: If you need to adjust Wasm loading behavioroptimizeDeps: {exclude: ['opencascade.js']  // Prevent Vite from pre-bundling the Wasm module}
});

重装另一个

pnpm install opencascade.js@beta

配置您的 Bundler | OpenCascade.js --- Configuring Your Bundler | OpenCascade.js

  initOpenCascade().then(oc => {// Initialize with explicit WASM file path configuration// Use the initialized oc object to create the boxconst box = oc.BRepPrimAPI_MakeBox(new oc.gp_Pnt_3(ox, oy, oz), // Note: Fixed typo `oc.gp_Pnt_3` → `oc.gp_Pnt`width,height,depth).Shape();// 创建 STEP 写入器const writer = new oc.STEPControl_Writer();// 设置 STEP 协议版本（AP203：仅几何数据；AP214：含机械属性）oc.Interface_Static_1("write.step.schema", "AP203");

有了

~~import initOpenCascade from "opencascade.js/dist/opencascade.full.js";~~

import initOpenCascade from "opencascade.js/dist/opencascade.full.wasm?init";

~~太酷了，和我的问题一模一样~~

Webpack 和vite什么区别

pnpm install --save-dev webpack-cli webpack-dev-server

webpack.config.js

module: {rules: [{test: /\.wasm$/,type: "javascript/auto",  // 避免 Webpack 默认解析为 JSONloader: "file-loader"     // 确保 WASM 文件被正确打包}]}// Webpack 5 配置（移除废弃的 `node` 字段）fallback: {fs: false;          // 不填充 Node.js 的 `fs` 模块（前端无需）perf_hooks: false;os: false;worker_threads: false;crypto: false;stream: false}
