Скачать или смотреть node_modules Missing from Volume After Successful npm Install Docker

The issue where node_modules is not present in a Docker volume after running npm install can occur due to how Docker volumes work. By default, Docker volumes can overwrite the container's file system, and if you're mounting a local volume, an empty or missing node_modules directory in the host can cause this problem


The best solution to ensure node_modules is present in your Docker container without being affected by the host system is to use a named volume for node_modules. This keeps node_modules inside the container and prevents it from being overwritten by the host.

1. Use a Named Volume for node_modules

Update your docker-compose.yml like this:

version: '3'
services:
app:
image: node:14
working_dir: /usr/src/app
volumes:
.:/usr/src/app # Mount project directory
node_modules:/usr/src/app/node_modules # Use named volume for node_modules
command: npm install

volumes:
node_modules:
