Environment Config Record

Environment variables arrive as strings, then scripts convert them into typed config.

env.ts

type EnvConfig = {
    debug: boolean;
    retries: number;
};

function readConfig(env: Record<string, string>): EnvConfig {
    return {
        debug: env.DEBUG === "true",
        retries: Number(env.RETRIES)
    };
}

const debugText: string = ;
const env: Record<string, string> = {
    DEBUG: debugText,
    RETRIES: "3"
};
const config: EnvConfig = readConfig(env);

console.log(`${config.debug ? "debug" : "normal"}:${config.retries}`);

type EnvConfig = {
    debug: boolean;
    retries: number;
};

function readConfig(env: Record<string, string>): EnvConfig {
    return {
        debug: env.DEBUG === "true",
        retries: Number(env.RETRIES)
    };
}

const debugText: string = ;
const env: Record<string, string> = {
    DEBUG: debugText,
    RETRIES: "3"
};
const config: EnvConfig = readConfig(env);

console.log(`${config.debug ? "debug" : "normal"}:${config.retries}`);

environment config A typed config object keeps string environment input at the edge of a script.
