envy

envy allows transparent access to both environment variables and .env file.

Description

Applications typically need to access configuration via environment variables.

• During development, the application has to read the .env file to obtain those variables
• In production, the application has to access shell environment variables via Deno.env

Ideally, the application should be able to access environment variables the same way, regardless of whether it’s supplied via the .env file or via shell.

envy makes that possible.

Usage

import { load } from "https://deno.land/x/envy/mod.ts";

const env = await load();

console.log(env["PORT"]);

envy loads both the .env file and the Deno.env object, then combine them into a single object. The application can then access the environment variables transparently. It follows these rules:

• It follows deno convention by using the standard library to load .env behind the scene
• If .env file does not exist, it simply ignores it and proceeds
• If the same variable exists in multiple places, shell environment variable takes precedence.
• envy creates a new object to hold the loaded environment variables, without modifying the Deno.env object.
