astro-env v0.0.6

astro-env

This is an Astro integration that allows you to validate and type your environement variables automatically using zod.

Usage

Installation

Install the integration automatically using the Astro CLI:

pnpm astro add astro-env

npm astro add astro-env

yarn astro add astro-env

Or install it manually:

1. Install the required dependencies

pnpm add astro-env

npm install astro-env

yarn add astro-env

2. Add the integration to your astro config

+import astroEnv from "astro-env";

export default defineConfig({
  integrations: [
+    astroEnv({ ... }),
  ],
});

Configuration

Here is the TypeScript type:

export type Options = {
    schema: AnyZodObject;
    generateTypes?: boolean;
    generateEnvTemplate?: boolean;
}

schema

Zod schema used to validate your environment variables. You can import zod from astro/zod:

import astroEnv from "astro-env";
import { defineConfig } from "astro/config";
import { z } from "astro/zod";

// https://astro.build/config
export default defineConfig({
	integrations: [
		astroEnv({
			schema: z.object({
				ABC: z.string(),
			}),
		}),
	],
});

When using generateTypes, make sure that the schema doesn't contain any transform and that all values are strings (they can be z.string().url() for example).

generateTypes

If set to true, generates .astro/astro-env.d.ts with types based on the schema and updates src/env.d.ts. Defaults to true.

generateEnvTemplate

If set to true, generates a .env.template with keys based on the schema. Defaults to false

Contributing

This package is structured as a monorepo:

pnpm i --frozen-lockfile

Start the playground:

pnpm playground:dev

You can now edit files in package. Please note that making changes to those files may require restarting the playground dev server.
