@neodx/fs

File system enhancements and common stuff.

API`s overview:

• scan(path, ['*.js', '*.module.ts', '!*.test.{ts,js}']) - glob reader with multiple inputs support
• ensureDir(path), ensureFile(path) - Safe file/dir creation with all required ancestors
• exists(path), isFile(path), isDirectory(path) - Safe path checks
• deepReadDir(path) - Deep version of readdir
• parseJson(input), serializeJson(input) - Safe JSON parser and serializer with JSONC support
• getFileHash(path), getHash(content) - Returns file hash based on its content (HEX)

API

scan

Glob-based (via tiny-glob) multiple patterns scanner with exclusion support

import { scan } from '@neodx/fs';

await scan(process.cwd(), ['*.js', '!*.config.js']);
await scan(process.cwd(), '**/*.ts', '**/*.js');

ensureFile(path) and ensureDir(path)

Recursively creates missed file or dir with all required ancestors if one of them is not exists.

Automatically avoid duplicated calls:

import { ensureFile, ensureDir } from '@neodx/fs';

// Everything works as expected
await Promise.all([
  ensureDir('foo/baz'),
  ensureFile('foo/bar/2.ts'),
  ensureDir('foo/bar'),
  ensureFile('foo/bar/1.ts'),
  ensureDir('foo')
]);

isFile, isDirectory, exists

The following APIs are useful for safe paths checking.

• exists(path) - Returns true if the path exists
• isFile(path) - Returns true if the path exists, and it's a file
• isDirectory(path) - Returns true if the path exists, and it's a directory

deepReadDir(path, { absolute = false })

Returns flat list with all children's paths. Paths are relative by default.

import { deepReadDir, isFile } from '@neodx/fs';

const files = await deepReadDir(myPath);

for (const file of files) {
  if (await isFile(file)) {
    await doSmth(file);
  }
}

parseJson and serializeJson

import { parseJson, serializeJson } from '@neodx/fs';
import { writeFile, readFile } from 'fs/promises';

const json = parseJson(await readFile('tsconfig.json', 'utf-8'));

await writeFile(
  'tsconfig.json',
  serializeJson({
    ...json,
    compilerOptions: {
      ...json.compilerOptions,
      target: 'esnext'
    }
  }),
  'utf-8'
);

Inspired by fs-extra and others.
