Dotenv

Dotenv handling for deno.

Usage

Setup a .env file in the root of your project.

.env

GREETING=hello world

Then import the configuration using the config function.

app.ts

import { config } from "https://raw.githubusercontent.com/pietvanzoen/deno-dotenv/v0.0.2/dotenv.ts";

console.log(config());

Then run your app.

> deno app.ts
{ GREETING: "hello world" }

path?: string: Optional path to .env file. Defaults to ./.env.
export?: boolean: Set to true to export all .env variables to the current processes environment. Variables are then accessable via deno’s env function. Defaults to false.

The parsing engine currently supports the following rules:

BASIC=basic becomes {BASIC: 'basic'}
empty lines are skipped
lines beginning with # are treated as comments
empty values become empty strings (EMPTY= becomes {EMPTY: ''})
single and double quoted values are escaped (SINGLE_QUOTE='quoted' becomes {SINGLE_QUOTE: "quoted"})
new lines are expanded if in double quotes (MULTILINE="new\nline" becomes

{MULTILINE: 'new
line'}

inner quotes are maintained (think JSON) (JSON={"foo": "bar"} becomes {JSON:"{\"foo\": \"bar\"}")
whitespace is removed from both ends of the value (see more on trim) (FOO=" some value " becomes {FOO: 'some value'})
