How to reduce the Docker image with a NodeJS application? Example reduction from 1.34GB to 157MB

This article discusses how to reduce the size of Docker images for Node.js applications, which is especially important for performance and efficient resource usage. The author explains that standard Node.js images can be quite large, leading to longer startup times and more data to transfer. They introduce various strategies that can be implemented to effectively reduce image size. These include using multi-stage builds and removing unnecessary files and dependencies, which contribute to a smaller overall image. The author provides concrete examples of how to implement these techniques and which tools can be useful in the process. It's also worth noting the importance of project organization, as well-thought-out directory structures can significantly impact the efficiency of Docker image builds.
