npx jsr add @miyauci/esbuild-deno-env

Usage

The denoEnvPlugin adds a mock Deno.env to the bundle through esbuild inject.

It receives the initial values of the environment variables.

import { denoEnvPlugin } from "@miyauci/esbuild-deno-env";
import { build } from "esbuild";

declare const env: { ENDPOINT: string };

await build({
  stdin: {
    contents: `Deno.env.get("ENDPOINT");`,
  },
  plugins: [denoEnvPlugin(env)],
  bundle: true,
  format: "esm",
});

output:

// deno-env:deno-env:
var DenoEnv = class {
  #env;
  constructor(init = {}) {
    this.#env = new Map(Object.entries(init));
  }
  get(key) {
    return this.#env.get(key);
  }
  set(key, value) {
    this.#env.set(key, value);
  }
  delete(key) {
    this.#env.delete(key);
  }
  has(key) {
    return this.#env.has(key);
  }
  toObject() {
    return Object.fromEntries(this.#env);
  }
};
var env = /* @__PURE__ */ new DenoEnv({ "ENDPOINT": "<ENDPOINT>" });

// <stdin>
console.log(env.get("ENDPOINT"));
