The public\n[`node` image from Docker Hub](https://hub.docker.com/_/node/)\ncomes preinstalled with the `npm` tool. You can configure Cloud Build\nto build your `Node.js` project with this tool.\n\nBefore you begin\n----------------\n\nThe instructions on this page assume that you are familiar with `Node.js`. In\naddition:\n\n- Be familiar with [npm](https://docs.npmjs.com/about-npm).\n- Have your `Node.js` project handy, including `package.json` and `test.js` files.\n- Make sure your `package.json` file includes a `start` script and a `test` script.\n- Be familiar with [how to write a Cloud Build configuration file](/build/docs/build-config).\n- Have an npm repository in Artifact Registry. If you don't have one, [create a new repository](/artifact-registry/docs/repositories/create-repos).\n- To run the `gcloud` commands in this page, install the [Google Cloud CLI](/sdk).\n\nBuilding with `npm`\n-------------------\n\nTo execute your tasks in the `node` image from Docker Hub, specify the image URL\nin the `name` field in the [Cloud Build config file](/build/docs/build-config-file-schema).\nCloud Build starts the container specified in the `name`\nfield using the image's default entrypoint. To override the default entrypoint\nand define how the build step should be run when it is invoked, add an\n`entrypoint` field in your build step. The `node` image in Docker Hub comes\npreinstalled with the `npm` tool. Specify the tools in the `entrypoint` field to\ninvoke them as the entrypoint of your build step.\n\nIn the following example build config file:\n\n- The `name` field specifies that the `node` image from Docker Hub is used by Cloud Build to execute your task. When you're specifying the `node` image, you can either omit the node version to default to `:latest`, or specify a [node version](https://hub.docker.com/_/node/) to use a specific version. For example, `name: node` will use the latest version of node, and `name: node:12` will use `node:12`.\n- The `entrypoint` field specifies that the `npm` tool is used\n when the `node` image is invoked.\n\n steps:\n - name: 'node'\n entrypoint: 'npm'\n\nConfiguring `Node.js` builds\n----------------------------\n\n1. In your project root directory, create a\n config file named `cloudbuild.yaml`.\n\n2. **Install dependencies** : Before you can build your application, you must\n ensure that all of your project's dependencies are installed from `npm`. You\n can install dependencies using the `install` command within the `npm` build\n step. The `args` field of a build step takes a list of arguments and passes\n them to the image referenced by the name field. In your build config file,\n add `install` to the `args` field to invoke the `install` command:\n\n steps:\n - name: 'node'\n entrypoint: 'npm'\n args: ['install']\n\n3. **Add tests** : If you've defined a `test` script in your `package.json`, you\n can configure Cloud Build to run the script by adding `test` to the\n `args` field:\n\n steps:\n - name: 'node'\n entrypoint: 'npm'\n args: ['install']\n - name: 'node'\n entrypoint: 'npm'\n args: ['test']\n\n4. **Run custom commands** : If your `package.json` contains any custom commands,\n you can configure Cloud Build to run that command. In the `args`\n field, add `run` as the first argument followed by the name of the custom\n command. The following build config file has arguments to run a custom\n command called `build`:\n\n steps:\n - name: 'node'\n entrypoint: 'npm'\n args: ['install']\n - name: 'node'\n entrypoint: 'npm'\n args: ['test']\n - name: 'node'\n entrypoint: 'npm'\n args: ['run', 'build']\n\n5. **Upload to Artifact Registry**:\n\n In your config file, add the `npmPackages` field and specify your npm\n repository in Artifact Registry: \n\n artifacts:\n npmPackages:\n - repository: 'https://\u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e-npm.pkg.dev/\u003cvar translate=\"no\"\u003ePROJECT-ID\u003c/var\u003e/\u003cvar translate=\"no\"\u003eREPOSITORY_NAME\u003c/var\u003e'\n packagePath: '\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nx\"\u003ePACKAGE_PATH\u003c/span\u003e\u003c/var\u003e'\n\n Replace the following values:\n - \u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e: the [location](/artifact-registry/docs/repo-locations) for your repository in Artifact Registry.\n - \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: the ID of the Google Cloud project that contains your Artifact Registry repository.\n - \u003cvar translate=\"no\"\u003eREPOSITORY_NAME\u003c/var\u003e: the name of your npm repository in Artifact Registry.\n - \u003cvar translate=\"no\"\u003ePACKAGE_PATH\u003c/var\u003e: the path for the local directory containing the npm package that you want to upload to Artifact Registry. We recommend using an absolute path. Your \u003cvar translate=\"no\"\u003ePACKAGE_PATH\u003c/var\u003e value can be `.` to use the current working directory, but the field cannot be omitted or left empty. This directory must contain a `package.json` file.\n6. **Optional: Enable provenance generation**\n\n Cloud Build can generate verifiable\n [Supply chain Levels for Software Artifacts (SLSA)](https://slsa.dev/) build\n provenance metadata to help secure your continuous integration pipeline.\n\n To enable provenance generation, add\n [`requestedVerifyOption: VERIFIED`](/build/docs/build-config-file-schema#options)\n to the `options` section in your config file.\n7. **Start your build** : [manually](/build/docs/running-builds/start-build-manually) or\n [using build triggers](/build/docs/automating-builds/create-manage-triggers).\n\n Once your build completes, you can [view repository details](/artifact-registry/docs/repositories/list-repos)\n in Artifact Registry.\n\n You can also [view build provenance metadata](/build/docs/securing-builds/generate-validate-build-provenance#view) and [validate provenance](/build/docs/securing-builds/generate-validate-build-provenance#validate_provenance).\n\nRunning tests on multiple `node` versions\n-----------------------------------------\n\nSometimes it is necessary to ensure that your project works across multiple\nversions of `node`. You can create and configure\n[Cloud Build triggers](/build/docs/running-builds/create-manage-triggers)\nsuch that:\n\n- In your build config file, specify the `node` version as a [substitution variable](/build/docs/configuring-builds/substitute-variable-values).\n- Create one trigger for each version of `node` against which you want to build your application.\n- In each of the trigger settings, use the substitution variable value field to indicate the version of the `node` for that trigger.\n\nThe following steps explain how to specify the `node` version using trigger-specific\nsubstitution variables:\n\n1. In your repository root, add a build config file, which specifies the\n `node`version as a substitution variable. In the following example build\n config file, `$_NODE_VERSION` is a [user-defined substitution variable](/build/docs/configuring-builds/substitute-variable-values#using_user-defined_substitutions):\n\n steps:\n - name: 'node:$_NODE_VERSION'\n entrypoint: 'npm'\n args: ['install']\n - name: 'node:$_NODE_VERSION'\n entrypoint: 'npm'\n args: ['test']\n\n2. For each version of `node` you want to build against, create a build trigger\n using the following steps:\n\n 1. Open the **Triggers** page in the Google Cloud console:\n\n [Open Triggers page](https://console.cloud.google.com/cloud-build/triggers)\n 2. Select your project from the project selector drop-down menu at the top of\n the page.\n\n 3. Click **Open**.\n\n 4. Click **Create trigger**.\n\n On the **Create trigger** page, enter the following settings:\n 1. Enter a name for your trigger.\n\n 2. Select the repository event to start your trigger.\n\n 3. Select the repository that contains your source code and build\n config file.\n\n 4. Specify the regex for the branch or tag name that will start your\n trigger.\n\n 5. **Configuration**: Choose the build config file you created\n previously.\n\n 6. Under **Substitution variables** , click **Add variable**.\n\n 1. Under **Variable** , specify the `node` version variable you used in your build config file, and under **Value** specify the version of the `node`. For example, `_NODE_VERSION` and `12`.\n 5. Click **Create** to save your build trigger.\n\nYou can use these triggers to build your code on the version of `node` you\nspecified in the trigger.\n\nWhat's next\n-----------\n\n- Learn how to [view build results](/build/docs/view-build-results).\n- Learn how to [safeguard builds](/software-supply-chain-security/docs/safeguard-builds).\n- Learn how to [build container images](/build/docs/building/build-containers).\n- Learn how to [build Go applications](/build/docs/building/build-go).\n- Learn how to [perform blue/green deployments on Compute Engine](/build/docs/deploying-builds/deploy-compute-engine).\n- Learn how to [troubleshoot build errors](/build/docs/troubleshooting)."]]
