property Process.mainModule

Usage in Deno

import { type Process } from "node:process";
Deprecated

Since v14.0.0 - Use main instead.

The process.mainModule property provides an alternative way of retrieving require.main. The difference is that if the main module changes at runtime, require.main may still refer to the original main module in modules that were required before the change occurred. Generally, it's safe to assume that the two refer to the same module.

As with require.main, process.mainModule will be undefined if there is no entry script.
