Deno Debug

Debug utility for deno.

Usage

import debug from "https://deno.land/x/debuglog/debug.ts";

// create debugger
const service = debug("service");

const serviceName = "app";

// log
service("booting %s", serviceName);

Then run your app.

> DEBUG=* deno run --allow-env app.ts

Todo

• extending debuggers
• custom log functions
• custom formatters
• log override in all namespaces
• inspect opts
• detecting color support
• non-tty env
• add debug to registry

Notes

• Currently debug assumes it is TTY and shows colors by default.
• Deno's inspect differs from node's util.inspect so the output may not be the same.
• We're using a custom format function ported from util. Might be cool to extract it when util is ported entirely.
• We should cover more functionality with tests.
