Usage

readPackageJSON

import { readPackageJSON } from "pkg-types";
const localPackageJson = await readPackageJSON();
// or
const packageJson = await readPackageJSON("/fully/resolved/path/to/folder");

writePackageJSON

import { writePackageJSON } from "pkg-types";

await writePackageJSON("path/to/package.json", pkg);

resolvePackageJSON

import { resolvePackageJSON } from "pkg-types";
const filename = await resolvePackageJSON();
// or
const packageJson = await resolvePackageJSON("/fully/resolved/path/to/folder");

readTSConfig

import { readTSConfig } from "pkg-types";
const tsconfig = await readTSConfig();
// or
const tsconfig2 = await readTSConfig("/fully/resolved/path/to/folder");

writeTSConfig

import { writeTSConfig } from "pkg-types";

await writeTSConfig("path/to/tsconfig.json", tsconfig);

resolveTSConfig

import { resolveTSConfig } from "pkg-types";
const filename = await resolveTSConfig();
// or
const tsconfig = await resolveTSConfig("/fully/resolved/path/to/folder");

resolveFile

import { resolveFile } from "pkg-types";
const filename = await resolveFile("README.md", {
  startingFrom: id,
  rootPattern: /^node_modules$/,
  matcher: (filename) => filename.endsWith(".md"),
});

resolveLockFile

Find path to the lock file (yarn.lock, package-lock.json, pnpm-lock.yaml, npm-shrinkwrap.json) or throws an error.

import { resolveLockFile } from "pkg-types";
const lockfile = await resolveLockFile(".");

findWorkspaceDir

Try to detect workspace dir by in order:

1. Nearest .git directory
2. Farthest lockfile
3. Farthest package.json file

If fails, throws an error.

import { findWorkspaceDir } from "pkg-types";
const workspaceDir = await findWorkspaceDir(".");

Types

Note: In order to make types working, you need to install typescript as a devDependency.

You can directly use typed interfaces:

import type { TSConfig, PackageJSON } from "pkg-types";

You can also use define utils for type support for using in plain .js files and auto-complete in IDE.

import type { definePackageJSON } from 'pkg-types'

const pkg = definePackageJSON({})

import type { defineTSConfig } from 'pkg-types'

const pkg = defineTSConfig({})
