| # 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 Node-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 (`.`). | |
