Build npm GitHub issues

ts-prune

Find potentially unused exports in your Typescript project with zero configuration.

asciicast Join the chat at https://gitter.im/ts-prune/community

Getting Started

ts-prune exposes a cli that reads your tsconfig file and prints out all the unused exports in your source files.

Installing

Install ts-prune with yarn or npm

# npm
npm install ts-prune --save-dev
# yarn
yarn add -D ts-prune

Usage

You can install it in your project and alias it to a npm script in package.json.

{
  "scripts": {
    "find-deadcode": "ts-prune"
  }
}

If you want to run against different Typescript configuration than tsconfig.json:

ts-prune -p tsconfig.dev.json

Examples

Configuration

ts-prune supports CLI and file configuration via cosmiconfig (all file formats are supported).

Configuration options

  • -p, --project - tsconfig.json path(tsconfig.json by default)
  • -i, --ignore - errors ignore RegExp pattern
  • -e, --error - return error code if unused exports are found
  • -s, --skip - skip these files when determining whether code is used. (For example, .test.ts? will stop ts-prune from considering an export in test file usages)

CLI configuration options:

ts-prune -p my-tsconfig.json -i my-component-ignore-patterns?

Configuration file example ts-prunerc:

{
  "ignore": "my-component-ignore-patterns?"
}

FAQ

How do I get the count of unused exports?

ts-prune | wc -l

How do I ignore a specific path?

ts-prune | grep -v src/ignore-this-path

How do I ignore a specific identifier?

You can either,

1. Prefix the export with // ts-prune-ignore-next
// ts-prune-ignore-next
export const thisNeedsIgnoring = foo;
2. Use grep -v to ignore a more widely used export name
ts-prune | grep -v ignoreThisThroughoutMyCodebase
