Possible bug in 3.1.2, import.meta.env.MODE always set to "development"

[jfranciscosousa]

No matter what I do, import.meta.env.MODE is always set to development in both snowpack dev and snowpack build. Reverting back to before 3.0.13 fixed the issue.

My config:

module.exports = {
  mount: {
    src: "/assets",
    static: { url: "/", static: true },
  },

  routes: [{ match: "routes", src: ".*", dest: "/index.html" }],

  plugins: [
    "@snowpack/plugin-postcss",

    "@snowpack/plugin-react-refresh",

    "@snowpack/plugin-typescript",

    "@snowpack/plugin-dotenv",

    [
      "@snowpack/plugin-webpack",
      {
        extendConfig: (config) => ({
          ...config,
          optimization: {
            ...config.optimization,

            splitChunks: {
              chunks: "all",
            },
          },
        }),
      },
    ],
  ],

  devOptions: {
    open: "none",
    output: "stream",
  },

  alias: {
    root: "./src",
  },
};
