any-remover

Automatically remove unnecessary explicit any types from TypeScript code.

Installation

npm install -g any-remover

Or use directly with npx:

npx any-remover

Usage

any-remover [options]

Options

| Option | Description | Default | |--------|-------------|---------| | -p, --project <path> | Path to tsconfig.json | ./tsconfig.json | | -d, --dry-run | Show what would be removed without making changes | false | | --include <glob> | Only process files matching this glob | - | | --exclude <glob> | Skip files matching this glob | - | | -v, --verbose | Show detailed progress | false | | --json | Output results as JSON | false | | -y, --yes | Skip interactive prompts and process all files | false | | --write-interval <ms> | Interval for periodic disk writes (ms) | 30000 |

Examples

Run on current project:

any-remover

Run on a specific tsconfig:

any-remover -p ./packages/core/tsconfig.json

Preview changes without modifying files:

any-remover --dry-run

Process only files in a specific directory:

any-remover --include "src/utils/**"

Run non-interactively with JSON output:

any-remover -y --json

How It Works

any-remover uses a two-phase approach:

1. Phase 1 - Removal: Tests each any type annotation to see if it can be completely removed (letting TypeScript infer the type).

2. Phase 2 - Replacement: For any types that cannot be removed, tests if they can be safely replaced with unknown.

The tool uses smart batch processing with binary search to efficiently test changes while ensuring the project continues to compile.

Requirements

• Your project must compile successfully before running any-remover
• Node.js >= 18.0.0
• TypeScript >= 4.7.0
