use ViteServer middleware mode as eggjs plugin 插件开发 - Egg
配置
通过 config/plugin.ts 配置启动 vite 插件:
export default {
vitePlugin: {
enable: true,
package: "@banshan-alec/egg-vite-middleware",
},
};在 config/config.${env}.ts 配置基础配置：
export default (appInfo: EggAppInfo) => {
return {
vitePluginConfig: {
dev: process.env.NODE_ENV === "development",
envModeKey: "NODE_ENV",
root: path.resolve(appInfo.baseDir, ".."),
configFile: path.resolve(appInfo.baseDir, "../vite.config.ts"),
},
cluster = {
listen: {
open: true, // 设置open: true 可以自动打开浏览器
port: 6019,
hostname: '0.0.0.0',
},
};
};
};模板渲染
本插件暴露一个 Service，renderTpl 用于注入必要的运行时，和处理模板渲染
逻辑参考 Server-Side Rendering | Vite
export default class HTMLController extends Controller {
async html() {
console.log("路由html", this.ctx.req.url);
if (process.env.NODE_ENV === "production") {
// Why? 使用ctx.render可以缓存模板，提高性能，vite.renderTpl使用的是fs读取html，不会缓存
await this.ctx.render(
"index.html",
{ appInfo: "xxx" },
{
viewEngine: "nunjucks",
}
);
} else {
await this.ctx.service.vite.renderTpl((code) => {
return html.replace(
"{{ appInfo }}",
`<script>Object.defineProperty(window,'MyEnv',{value:Object.freeze(${JSON.stringify(
{ appInfo: "xxx" }
)}),writable: false});</script>`
);
});
}
}
