Why do I get the error “JavaScript heap out of memory” during deployment?

The error FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory means your Node.js build process exceeded the available memory during deployment.

To resolve this issue, increase the Node.js memory limit.

Go to the Apps section of the DigitalOcean Control Panel, click your app, and then click the Settings tab.

Under the Environment Variables heading, click Edit, and then in the Keys field, type NODE_OPTIONS. In the Values field, type --max-old-space-size=4096. Then, redeploy your app.

If your build continues to fail with an out of memory error, try optimizing your build.
