import { readPackage } from "pkg-types";
const localPackage = await readPackage();
// or
const package = await readPackage("/fully/resolved/path/to/folder");Writes package data with format detection based on file extension.
import { writePackage } from "pkg-types";
await writePackage("path/to/package.json", pkg);
await writePackage("path/to/package.json5", pkg);
await writePackage("path/to/package.yaml", pkg);Finds the nearest package file (package.json, package.json5, or package.yaml).
import { findPackage } from "pkg-types";
const filename = await findPackage();
// or
const filename = await findPackage("/fully/resolved/path/to/folder");import { readPackageJSON } from "pkg-types";
const localPackageJson = await readPackageJSON();

const filename = await resolveFile("README.md", {
startingFrom: id,
rootPattern: /^node_modules$/,
matcher: (filename) => filename.endsWith(".md"),
});Find path to the lock file (yarn.lock, package-lock.json, pnpm-lock.yaml, npm-shrinkwrap.json, bun.lockb, bun.lock, deno.lock) or throws an error.
import { resolveLockFile } from "pkg-types";
const lockfile = await resolveLockFile(".");Try to detect workspace dir by in order:
- Farthest workspace file (
pnpm-workspace.yaml,lerna.json,turbo.json,rush.json,deno.json,deno.jsonc) - Closest
.git/configfile - Farthest lockfile
- Farthest
package.jsonfile
If fails, throws an error.
import { findWorkspaceDir } from "pkg-types";
const workspaceDir = await findWorkspaceDir(".");Finds closest .git/config file.
import { resolveGitConfig } from "pkg-types";
const gitConfig = await resolveGitConfig(".")Finds and reads closest .git/config file into a JS object.
import { readGitConfig } from "pkg-types";
const gitConfigObj = await readGitConfig(".")Stringifies git config object into INI text format and writes it to a file.
import { writeGitConfig } from "pkg-types";
await writeGitConfig(".git/config", gitConfigObj)Parses a git config file in INI text format into a JavaScript object.
import { parseGitConfig } from "pkg-types";
const gitConfigObj = parseGitConfig(gitConfigINI)Stringifies a git config object into a git config file INI text format.
import { stringifyGitConfig } from "pkg-types";
const gitConfigINI = stringifyGitConfig(gitConfigObj)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, GitConfig } 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({})import type { defineGitConfig } from 'pkg-types'
const gitConfig = defineGitConfig({})Published under the MIT license.
