WASM

WASM is a proper distribution-grade CLI, not a shell script. It ships on PyPI (pip install wasm-cli) and on the openSUSE Build Service with native packages for Ubuntu 22.04 LTS, 24.04 LTS, Debian 12, Fedora 40 and openSUSE. One install, one command, one server running.

How a deploy flows

The deployers/ registry

Framework detection is pluggable. Each target implements a small interface and registers itself; the CLI picks the right one based on the project contents.

# src/wasm/deployers/registry.py
REGISTRY = {
    'nextjs': NextJsDeployer,
    'nodejs': NodeJsDeployer,
    'vite': ViteDeployer,
    'python': PythonDeployer,
    'static': StaticDeployer,
    'docker-compose': DockerComposeDeployer,
    'monorepo': MonorepoDeployer,
}

What it handles for you

• Framework build — runs the right build step, handles lockfiles, caches.
• Web server — generates an Nginx or Apache vhost with sensible defaults (HTTP/2, gzip, security headers, asset caching).
• SSL — issues and renews certificates via Certbot, webroot method. Handles the HTTP-01 challenge during the switch.
• Systemd units — creates a service per app with auto-restart, journald logging, environment file, and resource limits.
• Databases — optional provisioning for MySQL, PostgreSQL, Redis and MongoDB with credentials stored in the service environment.
• Snapshots — every deploy snapshots the previous release. wasm rollback <app> swaps the symlink and restarts.
• Web dashboard — an optional UI for status, logs and one-click rollbacks, served over the same Nginx.

CLI ergonomics

$ wasm deploy --app bitbeet.dev --repo git@github.com:Perkybeet/bitbeet.git
▸ detecting framework        → static
▸ cloning + installing       → ok
▸ building                   → dist/ (15.2 MB)
▸ nginx vhost                → generated
▸ systemd unit               → bitbeet.dev.service
▸ SSL (letsencrypt)          → issued
▸ health check               → 200 OK
⟹ live at https://bitbeet.dev

This very site is deployed with WASM — the Nginx vhost serving bitbeet.dev came from the wasm deploy tooling.
