The text discusses the limitations of storing environment variables in Netlify serverless functions due to AWS Lambda's character limit. It introduces a handy build plugin, `netlify-plugin-inline-functions-env`, which allows developers to use longer environment variables by inlining them at build-time. This plugin can be installed via the Netlify UI or configuration files and offers options for controlling which environment variables are transformed. By using this plugin, developers can now store super-long environment variables without affecting their committed code, making it easier to manage sensitive data such as private keys and API keys.
