import.meta

The import.meta object is a way for a module to access information about itself. It's part of the JavaScript language, but its contents are not standardized. Each "host" (browser, runtime, etc) is free to implement any properties it wishes on the import.meta object.

Bun implements the following properties.

import.meta.dir;   // => "/path/to/project"
import.meta.file;  // => "file.ts"
import.meta.path;  // => "/path/to/project/file.ts"
import.meta.url;   // => "file:///path/to/project/file.ts"

import.meta.main;  // `true` if this file is directly executed by `bun run`
                   // `false` otherwise

import.meta.resolve("zod"); // => "file:///path/to/project/node_modules/zod/index.js"
