# 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 omitted it will
start checking from the current directory (`.`).
[checker tool]: ../tools/check-napi.js
