Managing applications¶

Many of the basic application management functions are the same for Cloud Platform-hosted Drupal applications. These functions include:

• Modifying views of applications
• Adding applications
• Renaming applications

For a full explanation of each of these functions, see Managing applications with the Cloud Platform interface.

Managing environments¶

The Cloud Platform implementation of Node.js uses separate environments to help you maintain a clear and orderly workflow as you develop, test, and publish your applications. An application is deployed on each of its environments, but each environment may be in a different state—possibly with a build artifact deployed. Each environment has a URL at which its application can be accessed, but only the production environment’s URL is designed to be visible to the application’s users (website visitors).

Acquia Node.js applications start with one production (Prod) environment, and one development (Dev) environments. See Resources and limitations for Node.js environments for infrastructure details.

• Development environments: Shared between customers
• Production environments: Dedicated to a single customer

Determining Node.js version on an environment¶

The Overview page for an environment displays the Node.js version installed on an environment. To check the version installed on an environment, complete the following steps:

1. Sign in to the Cloud Platform user interface.
2. In the breadcrumbs menu, click the triangle and select your organization, application, and environment to display the environment’s Overview page.
3. On the environment’s Overview page, scroll down to the Information section.

The Cloud Platform user interface displays the Node.js version at the bottom of the Information section as shown in the following example:

Configuring Node.js version on an environment¶

1. Sign in to the Cloud Platform user interface.
2. Select your application and environment.
3. Click the Configure icon. Cloud Platform will display the Configuration panel.

4. In the Configuration panel, select the Node version you want to use for the environment:

   
5. Click Save.

Developing your application¶

Development with Node.js on Cloud Platform requires you create pipelines for your code.

Based on the normal Pipelines workflow, after connecting your application to a repository, you must create your build definition file.

The Cloud Platform uses the conventional npm start command to start your Node.js application. Ensure that you have a snippet similar to the following in your application’s package.json file:

"scripts": {
    "start": "node index.js"
}

Update your Node.js application within the error-handling code so that the code can capture error information and display logs and error messages in log streaming. Node.js applications that capture logs through console.log() and error messages through console.error() can provide effective monitoring and troubleshooting.

Node.js applications on Cloud Platform have a docroot directory. This directory isn’t used by Node.js applications, and can be safely added to your .gitignore file.

          - 'echo Check task log for more details at $PIPELINE_JOB_URL'

Configuring Puppeteer¶

To use the Puppeteer package, add a .puppeteerrc.cjs file in the application root directory with the following content:

const {join} = require('path');

/**
* @type {import("puppeteer").Configuration}
*/
module.exports = {
// Changes the cache location for Puppeteer.
cacheDirectory: join(__dirname, 'browsers', 'puppeteer'),
};

You must replace __dirname with the directory in which you want to install Chrome. Puppeteer uses the specified directory to install and use the Chrome package. Therefore, you do not need the globally installed Chrome package.

For more information, see Puppeteer configuration.
