Dockerfile.dev

# Development container for documentdb-agentic-memory.
#
# Purpose: run `npm install`, `npm run build`, `npm test`, etc. without
# installing Node.js or build toolchain on the host machine.
#
# Usage (via compose.dev.yml):
#   docker compose -f compose.dev.yml run --rm dev npm install
#   docker compose -f compose.dev.yml run --rm dev npm run build
#   docker compose -f compose.dev.yml run --rm dev npm test

FROM node:20-bookworm-slim

# `better-sqlite3` is a native module and needs a C++ toolchain at install time.
# python3 / make / g++ cover that. `git` is handy for `npm` packages that pull
# from VCS, and `ca-certificates` lets npm reach the registry over TLS.
# `libcurl4` is needed by the `mongod` binary that mongodb-memory-server
# downloads for the integration tests; the slim base image omits it.

# The base image already provides a non-root `node` user at uid 1000.
# Pre-create the node_modules mountpoint owned by `node` so a fresh named
# volume inherits those permissions on first creation.
