I'm relatively new to modern JavaScript development and have become concerned about the number of dependencies pulled into even a small Nuxt frontend. I switched from Node to Deno and configured a 30-day minimum dependency age, but the dependency tree still contains an overwhelming number of files from many different sources. I now run the project inside a Podman container, and even run IntelliJ remotely inside that container so the IDE cannot accidentally execute an untrusted dependency directly on my host system. This is starting to feel excessive for a relatively simple project. What layered, practical approach do experienced developers recommend for reducing JavaScript supply-chain risk without turning local development into an overly complicated setup?

The simplest long-term improvement is reducing what you trust. Prefer a small number of well-maintained packages, avoid adding dependencies for trivial functionality, inspect transitive dependencies when practical, and wait before adopting newly published versions. Keep the lockfile under version control and review changes to it carefully. For a frontend project, a container is a sensible extra boundary, especially for development tools, but running the entire IDE remotely may be more isolation than most projects need unless your threat model is particularly strict.
Use the controls provided by your package manager. Keep the configuration in the repository, enforce a minimum release age, disable dependency lifecycle scripts by default, and only allow scripts from packages you have reviewed. Similar options exist across current JavaScript package managers, so you don’t necessarily need to change runtimes just for this. Also review updates instead of blindly installing the newest versions, and run dependency checks as part of continuous integration.
There probably isn’t a single setting that completely prevents supply-chain attacks. A practical approach is to layer mitigations: commit and verify the lockfile so installs are deterministic, keep the dependency tree as small as possible, block lifecycle or install scripts unless they’re explicitly needed, scan dependencies in CI, and use a minimum release age such as 24–48 hours or longer. Containers are also reasonable for reducing the blast radius if something malicious does execute. Your current setup is more cautious than average, but the main goal is limiting damage rather than achieving perfect prevention.
That makes sense. I was treating the container as a way to prevent the problem entirely, but limiting the impact is probably the more realistic goal.
Age limits and script restrictions help, but they don’t solve everything. A compromised package can still be malicious after it has aged, so they should be treated as additional safeguards rather than a complete fix.
