Template Rendering

This plugin exposes a Service with renderTpl method for injecting necessary runtime and handling template rendering.

The logic refers to Server-Side Rendering | Vite

export default class HTMLController extends Controller {
  async html() {
    console.log("route html", this.ctx.req.url);
    if (process.env.NODE_ENV === "production") {
      // Why? Using ctx.render can cache templates to improve performance, while vite.renderTpl uses fs to read html without caching
      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>`
        );
      });
    }
