# Checker Tool

**node-addon-api** provides a [checker tool][] that will inspect a given
directory tree, identifying all Node.js native addons therein, and further
indicating for each addon whether it is an N-API addon.

## To use the checker tool:

  1. Install the application with `npm install`.

  2. If the application does not depend on **node-addon-api**, copy the
     checker tool into the application's directory.

  3. If the application does not depend on **node-addon-api**, run the checker
     tool from the application's directory:

     ```sh
     node ./check-napi.js
     ```

     Otherwise, the checker tool can be run from the application's
     `node_modules/` subdirectory:

     ```sh
     node ./node_modules/node-addon-api/tools/check-napi.js
     ```

The tool accepts the root directory from which to start checking for Node.js
native addons as a single optional command line parameter. If ommitted it will
start checking from the current directory (`.`).
