[Install Node.js and NPM](/nodejs/docs/setup).\n\nSet up a Sensitive Data Protection CLI app\n------------------------------------------\n\nTo set up a Sensitive Data Protection CLI app using Node.js, do the following:\n\n1. Clone the [Node.js DLP client library](https://github.com/GoogleCloudPlatform/nodejs-docs-samples):\n\n git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples\n\n2. Navigate to the `dlp` directory.\n\n cd nodejs-docs-samples/dlp\n\n3. Install the app dependencies:\n\n npm install\n\nInspect a string for sensitive information\n------------------------------------------\n\nTo scan sample text by using the DLP API and the `inspectString`\nNode.js script, run the following command: \n\n node inspectString.js \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e \"My email address is joe@example.com.\"\n\nThe output is similar to the following: \n\n Findings:\n Info type: EMAIL_ADDRESS\n Likelihood: LIKELY\n\nClean up\n--------\n\n\nTo avoid incurring charges to your Google Cloud account for\nthe resources used on this page, delete the Google Cloud project with the\nresources.\n\n### Delete the project\n\nIf you created a new project for this quickstart, the easiest way to prevent\nadditional charges is to delete the project.\n\n| **Caution** : Deleting a project has the following effects:\n|\n| - **Everything in the project is deleted.** If you used an existing project for the tasks in this document, when you delete it, you also delete any other work you've done in the project.\n| - **Custom project IDs are lost.** When you created this project, you might have created a custom project ID that you want to use in the future. To preserve the URLs that use the project ID, such as an `appspot.com` URL, delete selected resources inside the project instead of deleting the whole project.\n|\n|\n| If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects\n| can help you avoid exceeding project quota limits.\n1. Delete a Google Cloud project: \n\n```\ngcloud projects delete PROJECT_ID\n```\n\n\u003cbr /\u003e\n\n### Revoke your credentials\n\n1.\n Optional: Revoke the authentication credentials that you created, and delete the local\n credential file.\n\n ```bash\n gcloud auth application-default revoke\n ```\n2.\n Optional: Revoke credentials from the gcloud CLI.\n\n ```bash\n gcloud auth revoke\n ```\n\nWhat's next\n-----------\n\n- To get started with inspecting text and images for sensitive data, see\n [How-to guides](/sensitive-data-protection/docs/how-to).\n\n- To better understand inspection, redaction, infoTypes, and likelihood, see\n [Concepts](/sensitive-data-protection/docs/concepts).\n\n- Learn more about the [DLP API](/sensitive-data-protection/docs/reference/rest/v2).\n\n- Learn more about the [Cloud DLP Node.js Client](/nodejs/docs/reference/dlp/latest)."]]
