Mitigating Supply-Chain Risks with DevContainers and 1Password in Node.js Local Development
This article describes how to reduce the risk of npm supply-chain attacks by isolating the local development environment and avoiding storing secrets on disk. The proposed setup uses VS Code DevContainers to run your project inside a container, separating it from the host’s filesystem and credentials. Secrets (API tokens, etc.) are managed via the 1Password CLI and a Connect server so that they are injected just-in-time into the container rather than being kept in .env
files or environment variables on the host. Best practices include rotating tokens, locking down permissions, ensuring secret files are ignored by version control, and cleaning up temporary secret files.
