Because Vite statically replaces `import.meta.env`, you cannot access it with dynamic keys like `import.meta.env[key]`.

When using SSR, environment variables can be accessed at runtime based on the SSR adapter being used. With most adapters you can access environment variables with `process.env`, but some adapters work differently. For the Deno adapter, you will use `Deno.env.get()`. See how to [access the Cloudflare runtime](/en/guides/integrations-guide/cloudflare/#cloudflare-runtime) to handle environment variables when using the Cloudflare adapter. Astro will first check the server environment for variables, and if they don't exist, Astro will look for them in .env files.
