Node.js utilities and TypeScript definitions for `package.json` and `tsconfig.json`.

## Install

```sh
# ✨ Auto-detect
npx nypm install pkg-types

# npm
npm install pkg-types

# yarn
yarn add pkg-types

# pnpm
pnpm install pkg-types

# bun
bun install pkg-types

# deno
deno install pkg-types
```

## Usage

### `readPackageJSON`

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

### `writePackageJSON`

```js
import { writePackageJSON } from "pkg-types";

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

### `resolvePackageJSON`

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

### `readTSConfig`

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

### `writeTSConfig`

```js
import { writeTSConfig } from "pkg-types";

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

### `resolveTSConfig`

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

### `resolveFile`

```js
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`, `bun.lockb`, `bun.lock`) or throws an error.

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

### `findWorkspaceDir`

Try to detect workspace dir by in order:

1. Farthest workspace file (`pnpm-workspace.yaml`, `lerna.json`, `turbo.json`, `rush.json`)
2. Closest `.git/config` file
3. Farthest lockfile
4. Farthest `package.json` file

If fails, throws an error.

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

### `resolveGitConfig`

Finds closest `.git/config` file.

```js
import { resolveGitConfig } from "pkg-types";

const gitConfig = await resolveGitConfig(".")
```

### `readGitConfig`

Finds and reads closest `.git/config` file into a JS object.

```js
import { resolveGitConfig } from "pkg-types";

const gitConfigObj = await readGitConfig(".")
```

### `writeGitConfig`

Stringifies git config object into INI text format and writes it to a file.

```js
import { writeGitConfig } from "pkg-types";

await writeGitConfig(".git/config", gitConfigObj)
```

### `parseGitConfig`

Parses a git config file in INI text format into a JavaScript object.

```js
import { parseGitConfig } from "pkg-types";

const gitConfigObj = parseGitConfig(gitConfigINI)
```

### `stringifyGitConfig`

Stringifies a git config object into a git config file INI text format.

```js
import { parseGitConfig } from "pkg-types";

const gitConfigINI = stringifyGitConfig(gitConfigObj)
```

## Types

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

You can directly use typed interfaces:

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

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

```js
import type { definePackageJSON } from 'pkg-types'

const pkg = definePackageJSON({})
```

```js
import type { defineTSConfig } from 'pkg-types'

const pkg = defineTSConfig({})
```

```js
import type { defineGitConfig } from 'pkg-types'

const gitConfig = defineGitConfig({})
```
