It will then forward the requests to the myapp application. What’s going on?Īt this point of the tutorial, the URL of the web application will be requested instead of the myapp URL. Īlternately, specify the start command with cf push -c.This command will update the myapp application and deploy the web application. This saves a manifest.yml in your app with the settings youĮdit the manifest.yml file and create a start command as follows: - applications : - name : my-app command : node my-app.js. The first time you deploy, you are asked if you want to save your configuration. For more information about Procfiles, see the Configuring a Production Server topic. You can specify the web start command for a Node.js app in a Procfile or in the app deployment manifest. This sets max_old_space_size based on the available memory in the instance. To resolve this issue, set the OPTIMIZE_MEMORY environment variable to true (requires node v6.12.0 or greater). Node does not know how much memory it isĪllowed to use, and thus sometimes allows the garbage collector to wait past When running node apps, you might notice that instances are occasionally ![]() To also run your app locally, set the default port as 3000. You must use the PORT environment variable to determine which port yourĪpp should listen on. See the GitHub Node.js buildpack page for current information. In general, Cloud Foundry supports the two most recent versions of Node.js. You can specify the version of Node.js you want to use in the engine node of Application package fileĬloud Foundry expects a package.json in your Node.js app. To specify the versions of Node.js and npm an app requires, edit the app’s package.json, as described in “node.js and npm versions” in the nodejs-buildpack repository. The buildpack uses a default Node.js version. You can find current information about this buildpack on the Node.js buildpack release page in GitHub. About the Node.js buildpackįor information about using and extending the Node.js buildpack in Cloudįoundry, see the nodejs-buildpack repository in GitHub. This topic provides Node-specific information to supplement the general guidelines in the Pushing an App topic.
