Environment Variables

​

What’s in the environment

​

Declaring variables

[edge_compute]
func_id   = "7819cf01-39a8-400e-9bce-3d792ffa4017"
func_name = "demo-ts"

[env_vars]
LOG_LEVEL   = "info"
MAX_RETRIES = "3"
DEBUG       = "false"

• All values are strings. Parse numbers and booleans in your code.
• Changes take effect on the next telnyx-edge ship — there is no live update.
• Names share the env namespace with bindings. If an [env_vars] entry has the same name as a declared binding — or is named SECRETS while a [[secrets]] block is declared — ship warns that one shadows the other on env and still proceeds; rename one. (A binding named SECRETS, or a duplicate [[secrets]] handle, is a hard error.)

Reading variables

const port = Number(process.env.PORT ?? 8080);         // set by the platform
const logLevel = process.env.LOG_LEVEL ?? "info";      // from [env_vars]
const maxRetries = Number(process.env.MAX_RETRIES ?? "3");
const debug = process.env.DEBUG === "true";

import os

log_level = os.environ.get("LOG_LEVEL", "info")
max_retries = int(os.environ.get("MAX_RETRIES", "3"))
debug = os.environ.get("DEBUG", "false").lower() == "true"

package function

import (
    "os"
    "strconv"
)

func loadConfig() (logLevel string, maxRetries int, debug bool) {
    logLevel = os.Getenv("LOG_LEVEL")
    if logLevel == "" {
        logLevel = "info"
    }
    maxRetries, _ = strconv.Atoi(os.Getenv("MAX_RETRIES"))
    debug, _ = strconv.ParseBool(os.Getenv("DEBUG"))
    return
}

String logLevel = System.getenv().getOrDefault("LOG_LEVEL", "info");
int maxRetries = Integer.parseInt(System.getenv().getOrDefault("MAX_RETRIES", "3"));
boolean debug = Boolean.parseBoolean(System.getenv("DEBUG"));

Environment variables vs secrets

Next Steps

• Secrets — the server-side counterpart for sensitive values, including the typed env.SECRETS surface for TypeScript
• Bindings — typed, pre-authenticated handles instead of raw variables
• Configuration — the full manifest reference: every func.toml and telnyx.toml key
