Provider Detection

std-env can automatically detect the current runtime provider based on environment variables.

You can use isCI and platform exports to detect it:

import { isCI, platform, platformInfo } from "std-env";

console.log({
  isCI, // true
  platform, // "github_actions"
  platformInfo, // { name: "github_actions", isCI: true }
});

If you want to test provider based on a custom environment variable set, you can also directly use detectProvider:

import { detectProvider } from "std-env";

// { name: "vercel", ci: false }
console.log(detectProvider({ VERCEL: "1" }));

List of well known providers can be found from ./src/providers.ts.

Platform agnotic env

std-env provides a lightweight proxy to access environment variables in a platform agnostic way.

import { env } from "std-env";

Platform agnostic process

std-env provides a lightweight proxy to access process object in a platform agnostic way.

import { process } from "std-env";
