ZENV

ZENV is a TypeScript library for validating and parsing environment variables. It is based on the popular Zod library, which provides a simple and intuitive API for defining and validating data schemas.

Installation

To install ZENV, use npm:

npm install @d6v/zenv

Usage

To use ZENV, first define a schema for your configuration file using the Zod API. Then, use the parse function provided by ZENV to parse and validate your configuration file.

Here's an example:

import { z } from "zod";
import { zenv } from "@d6v/zenv";

const schema = z.object({
  port: z.number().min(0).max(65535),
  host: z.string().optional(),
  debug: z.boolean().optional(),
});

const validatedEnv = zenv(schema);

In this example, we define a schema for a configuration file that has three properties: port, host, and debug. The port property is required and must be a number between 0 and 65535. The host and debug properties are optional and can be either a string or a boolean, respectively.

API

ZENV provides the following API:

zenv(schema: z.ZodSchema, options: ZenvOptions): z.infer<z.ZodSchema> Parses and validates an env variables object using the given Zod schema. Returns an object with the parsed values if the object is valid, or throws an error with a detailed error message if the object is invalid.

Options

The zenv function accepts an optional options object as its second argument. The following options are available:

interface ZenvOptions {
  env?: process.env;
  parser?: (value: any) => any;
  useDotenv?: boolean;
  dotenvConfig?: DotenvConfigOptions;
}
