Nitropack should not override NODE_ENV when run command nuxt generate.

[kaokei]

I am developing an SSG project using Nuxt and Ant Design Vue. When I run the nuxt generate command, initially, the NODE_ENV is indeed set to production, which is as expected. However, during the pre-rendering phase, the NODE_ENV is overridden to prerender.

This results in Ant Design Vue generating incorrect class name prefixes. The relevant code is as follows:

File Path: ant-design-vue/es/_util/cssinjs/hooks/useCacheToken.js

const hashPrefix = process.env.NODE_ENV !== 'production' ? 'css-dev-only-do-not-override' : 'css';

The code that overrides NODE_ENV in Nitropack is as follows:

  nitro.logger.info("Initializing prerenderer");
  nitro._prerenderedRoutes = [];
  nitro._prerenderMeta = nitro._prerenderMeta || {};
  const prerendererConfig = {
    ...nitro.options._config,
    static: false,
    rootDir: nitro.options.rootDir,
    logLevel: 0,
    preset: "nitro-prerender"
  };

And

  let NODE_ENV = nitro.options.dev ? "development" : "production";
  if (nitro.options.preset === "nitro-prerender") {
    NODE_ENV = "prerender";
  }
  const buildEnvVars = {
    NODE_ENV,
    prerender: nitro.options.preset === "nitro-prerender",
    server: true,
    client: false,
    dev: String(nitro.options.dev),
    DEBUG: nitro.options.dev
  };
