New API + Sub2API Stack Installer

An npm CLI that installs the upstream New API and Sub2API Docker stacks on a Linux host. It generates credentials locally, creates two isolated Compose networks, pulls upstream images, starts the services, and verifies their HTTP health endpoints.

Requirements

• Linux with Node.js 20 or newer and npx
• Docker Engine with a running daemon
• Docker Compose plugin (docker compose)
• The current user must be able to run docker info without sudo
• Network access to the npm registry and Docker Hub

Node.js is only needed to run this installer. The applications themselves run entirely in Docker.

Run Locally

From this package directory:

npx --yes . install

Until the package is published, it can also be run by absolute directory:

npx --yes /home/ubuntu/newapi-sub2api-installer install

After publication to npm:

npx --yes @yibi/[email protected] install

Production automation should specify an exact npm package version instead of @latest.

Commands

api-stack install
api-stack status
api-stack logs
api-stack logs --service new-api
api-stack update
api-stack uninstall
api-stack uninstall --purge --confirm-purge

The default installation directory is ~/.local/share/api-stack. Override it for every command with --install-dir, or set API_STACK_INSTALL_DIR.

Example unattended installation:

npx --yes @yibi/[email protected] install \
  --new-api-host 0.0.0.0 \
  --new-api-port 3000 \
  --sub2api-host 127.0.0.1 \
  --sub2api-port 8081 \
  --timezone Asia/Shanghai

Installed Services

The generated Compose project contains two isolated networks:

new-api-network                 sub2api-network
  new-api                        sub2api
  new-api-postgres               sub2api-postgres
  new-api-redis                  sub2api-redis

Defaults follow the upstream deployment layouts:

• calciumion/new-api:latest, PostgreSQL 15, and Redis
• weishaw/sub2api:latest, PostgreSQL 18 Alpine, and Redis 8 Alpine
• New API listens on 0.0.0.0:3000
• Sub2API listens on 127.0.0.1:8081
• Databases and Redis are not exposed on host ports

Use --new-api-image and --sub2api-image to pin application tags or digests.

Credentials and Data

Credentials are generated with Node's cryptographic random generator and stored in .env with mode 0600. They are never embedded in docker-compose.yml or printed by the installer. The generated Sub2API admin password is stored as SUB2API_ADMIN_PASSWORD in that file. New API completes its initial administrator setup in the web interface.

uninstall preserves all volumes and configuration. Permanent removal requires both --purge and --confirm-purge.

Publishing

Verify the package before publishing:

npm test
npm pack --dry-run
npm publish

The package is published publicly under the @yibi npm organization scope.
