vars — EdgeSpark variables - EdgeSpark Documentation

vars reads plain runtime configuration values from the current environment. Use it for non-sensitive values such as URLs, client IDs, feature flags, and log levels.

`vars.get(name)`

Declare the key in server/src/defs/runtime.ts, then read it in your route code:

server/src/index.ts

import { vars } from "edgespark";
import { Hono } from "hono";

const app = new Hono().get("/api/public/config", (c) => {
  return c.json({
    apiBaseUrl: vars.get("PUBLIC_API_BASE_URL"),
  });
});

export default app;

vars.get(...) returns string | null.

Manage vars

edgespark var list
edgespark var set PUBLIC_API_BASE_URL=https://api.example.com
edgespark var delete PUBLIC_API_BASE_URL

Use platform limits for current var naming and quota constraints.

Manage variables

Set, delete, and organize runtime vars in the repo-based workflow.

secret reference

Use secrets instead when the value is sensitive.
