The article appears to be outdated, the replace function has to contain something like this. Check the readme for plugin replace.

add this to the rollup.config.js


replace({
      values: {
        __myapp: JSON.stringify({
            isProd: production,
          ...config().parsed
        }),
      },
    }),

App.svelte file.

<script>
  console.log(__myapp);
  const { isProd, API_URL } = __myapp;
</script>

<h4>{isProd} - {API_URL}</h4>
