* Find the package.json file, either from a TypeScript file somewhere not
11 +
* in a 'dist' folder, or a built and/or installed 'dist' folder.
12 +
*
13 +
* Note: this *only* works if you build your code into `'./dist'`, and that the
14 +
* source path does not also contain `'dist'`! If you don't build into
15 +
* `'./dist'`, or if you have files at `./src/dist/dist.ts`, then this will
16 +
* not work properly!
17 +
*
18 +
* The default `pathFromSrc` option assumes that the calling code lives one
19 +
* folder below the root of the package. Otherwise, it must be specified.
20 +
*
21 +
* Example:
22 +
*
23 +
* ```ts
24 +
* // src/index.ts
25 +
* import { findPackageJson } from 'package-json-from-dist'
26 +
*
27 +
* const pj = findPackageJson(import.meta.url)
28 +
* console.log(`package.json found at ${pj}`)
29 +
* ```
30 +
*
31 +
* If the caller is deeper within the project source, then you must provide
32 +
* the appropriate fallback path:
33 +
*
34 +
* ```ts
35 +
* // src/components/something.ts
36 +
* import { findPackageJson } from 'package-json-from-dist'
37 +
*
38 +
* const pj = findPackageJson(import.meta.url, '../../package.json')
39 +
* console.log(`package.json found at ${pj}`)
40 +
* ```
41 +
*
42 +
* When running from CommmonJS, use `__filename` instead of `import.meta.url`
43 +
*
44 +
* ```ts
45 +
* // src/index.cts
46 +
* import { findPackageJson } from 'package-json-from-dist'
47 +
*
48 +
* const pj = findPackageJson(__filename)
49 +
