Create a dockerignore template for Node.js/JavaScript projects

Creates a dockerignore template with patterns to ignore Node.js and JavaScript related files and directories. `

Usage

dk_template_ignore_node(.dockerignore = NULL)

Arguments

.dockerignore

Optional existing dockerignore object to add patterns to

Value

A dockerignore object with Node.js-related ignore patterns

Details

This template adds patterns to ignore Node.js and JavaScript related files and directories, including:

• node_modules/: Package dependencies

• npm-debug.log*, yarn-error.log*: Package manager logs

• package-lock.json, yarn.lock: Lock files

• .npm/, .yarn/: Cache directories

• *.tgz: Packaged modules

• .pnp.*: Plug'n'Play files

• .cache/: Build cache

• .eslintcache: ESLint cache

These files are typically not needed in a Docker image or can be regenerated during the build process. Ignoring them can significantly reduce the build context size, especially node_modules/ which can be very large.
