Overview

Process arguments, environment variables, and the working directory.

Everything here reads or writes the environment of the running process itself. Nothing is read from a .env file and nothing is cached to disk: what you see is what the process inherited at start, plus whatever you write with Env.set after that.

.rnx

import { Env } from "@std/env";

Env.set("GREETING", "hi");
print(Env.get("GREETING"));
print(Env.get("NOT_SET_ANYWHERE") == "");
print(Env.cwd().len() > 0);

When to use it

Reach for @std/env when a program reads its configuration from the outside: CLI arguments, environment variables, or the current directory. Process.run covers spawning; Env covers reading.
