Debug

This module exports a single function dbg that prints a variable and return it.

Its taken from rust dbg! macro. The nice thing about it that it can be inserted anywhere, see below for an example.

This is very useful for debugging.

Examples

Example 1

import dbg from "@sigma/dbg";

// the nice thing is that `dbg` can be inserted anywhere
const fn1 = () => 4;
const fn2 = (n: number) => n + 1;
let value = fn2(dbg(fn1()));

// output: var = 4

Browsers:

Browsers and runtimes that don't support node apis, should use @sigma/dbg/browser entrypoint.

Note: Bun currently does not support util.callSites so it should also import from @sigma/dbg/browser.
