migrate-to-lodash-es

Easily migrate your JavaScript/TypeScript imports from lodash to lodash-es in seconds.

This CLI tool scans your project files and rewrites:

// Before
import { isEmpty, omitBy, pickBy, without } from 'lodash'

into:

// After
import isEmpty from 'lodash-es/isEmpty'
import omitBy from 'lodash-es/omitBy'
import pickBy from 'lodash-es/pickBy'
import without from 'lodash-es/without'

✨ Features

• Recursively scans directories
• Works on .js, .ts, .tsx files
• Supports both named and single imports
• Can migrate entire projects or a single file
• Keeps all other code intact

📦 Installation

npm install -g migrate-to-lodash-es

🚀 Usage

Migrate a whole project

migrate-to-lodash-es ./src

Migrate a single file

migrate-to-lodash-es src/pages/component/component.tsx

💡 Example

Before

import { isEmpty, omitBy } from 'lodash'
import without from 'lodash'

After

import isEmpty from 'lodash-es/isEmpty'
import omitBy from 'lodash-es/omitBy'
import without from 'lodash-es/without'

⚙️ Options (coming soon)

• --dry-run → Show what would change without modifying files
• --backup → Save .bak files before migration

📂 Supported File Types

• .js
• .jsx
• .ts

🛠 How it works

The tool:

1. Reads your file(s)
2. Finds imports from lodash
3. Converts them into individual ESM imports from lodash-es
4. Writes the changes in place
