[!CAUTION] Under active development - breaking changes often. Some documentation may be out of date, or not aligned with function. Wait until first release.

Overview

The web-template is a project that will enable the quick-start for a high-performance web application. The project goals are:

  • Performance: the project must meet or exceed the very highest performance expectations in all cases
  • Secure: the project must be provably secure, using the latest cryptographic techniques and best practices in all cases
  • High quality: the code must be provably high-quality, with all static analysis and code quality check turned to 11!
  • Lightweight: we need to ensure that the application uses the smallest possible memory and storage footprint, both on the server and in the browser
  • Easy to use: usage of web application, the developer experience, and operation of the application should be first class
  • Functional: the web application in particular must be able to leverage modern web application tools, extensions and widgets easily, to make development fast and easy.

This foundation is built using a SvelteKit frontend and a Rust backend, further detailed in the Architecture section.

Specific Goals (from PRD.md)

To achieve the above, the project will deliver on the following specific requirements:

  • Fast, modular Rust server supporting:
    • Database access (SQLite initially, using sqlx).
    • Easy integration of server-side components.
    • Generative AI integration (configurable for various providers like OpenAI, Gemini, Mistral).
  • Highly secure user registration, authentication, and profile management.
    • Initial auth providers: Local (email/password) and Google OAuth.
  • Payment integration using Stripe.
  • Deployment targets: GCP Cloud Run, Vercel, Supabase.

Architecture

The project is structured into two main components:

  • client/: A SvelteKit application responsible for the user interface and client-side logic. It is written in TypeScript and uses Bun for package management.
  • server/: A Rust application using the Axum framework for the backend REST API. It handles business logic, database interaction (via sqlx), and integrations with external services. Cargo is used for package management.

Key Technologies:

  • Frontend (Client):
    • Svelte / SvelteKit
    • TypeScript
    • Bun (Package Manager, Bundler, Test Runner)
    • Vite (Build Tool)
    • Playwright (E2E Testing)
    • Prettier (Formatting)
    • ESLint (Linting)
  • Backend (Server):
    • Rust
    • Axum (Web Framework)
    • Tokio (Async Runtime)
    • SQLx (Database Interaction)
    • Cargo (Package Manager & Build Tool)
    • clippy (Linting)
  • Database:
    • SQLite (for local development, configurable for production)
    • sqlx-cli (for database migrations)
  • Tooling & Orchestration:
    • just (Command runner for managing project tasks)
    • overmind (or similar, for running multiple processes locally, e.g., client and server dev servers)
    • direnv (for managing environment variables via .envrc - which is gitignored)
    • Git pre-commit hooks (for automated quality checks)

Getting Started

  1. Prerequisites:

  2. Clone the repository.

    git clone <repository-url> # Replace <repository-url> with the actual URL
cd <repository-name>/web-template # Replace <repository-name>

  3. Setup Environment:

    • If it doesn't exist, copy web-template/example.envrc to web-template/.envrc.
      cp .envrc.example .envrc
    • Fill in the required environment variables in .envrc:
      • DATABASE_URL: SQLite database connection string (e.g., sqlite:./db/dev.sqlite3?mode=rwc)
      • JWT_SECRET: A secure 32+ character secret key for JWT token signing
      • GOOGLE_CLIENT_ID: Your Google OAuth client ID from Google Console
      • GOOGLE_CLIENT_SECRET: Your Google OAuth client secret from Google Console
      • SERVER_URL: Your server URL (default: http://localhost:8081)
    • Run direnv allow in the project root (web-template/) to load the environment variables.

  4. Install Pre-commit Hooks:

    • Run pre-commit install to set up the git hooks defined in .pre-commit-config.yaml. This ensures code quality checks are run before each commit.

  5. Initial Project Setup (Clean Install & Build):

    • Run just setup. This command cleans previous build artifacts and dependencies, then installs fresh dependencies for both client and server, and performs an initial build.

  6. Database Setup:

    • Run just db-setup to apply database migrations using sqlx. This will create the necessary tables in your database.

  7. OAuth Configuration (Required for Authentication):

    • Create a Google Cloud Project at Google Cloud Console
    • Enable the Google OAuth 2.0 API
    • Create OAuth 2.0 credentials:
      • Go to "Credentials" → "Create Credentials" → "OAuth client ID"
      • Choose "Web application"
      • Add authorized redirect URIs: http://localhost:8081/api/auth/oauth/google/callback (development)
      • Note the Client ID and Client Secret for your .envrc file
    • Note: This application uses an invite-only system. Users must be invited before they can register via OAuth or email/password.

  8. Run the application (Development):

    • Run just dev. This will start both the client and server development servers using Overmind (ensure Procfile.dev is configured in web-template/).
    • Client is typically available at http://localhost:5173 (or as configured by Vite/SvelteKit).
    • Server is typically available at http://localhost:3000 (or as configured in server/.env if applicable, or Rocket.toml for Rocket).

Project Management

All common development tasks are managed via the justfile located in the web-template directory. Run just in the terminal from this directory to see a list of available commands.

Key command categories include:

  • setup: For initial project setup (cleans, installs all dependencies, and builds). (just setup)
  • dev: For running development servers using Overmind. (just dev). For individual servers: just client-dev-server or just server-dev-server [--hotreload].
  • build: For building client and server for production. (just build, just build-client, just build-server)
  • check: For running linters, type checkers, and formatters (in check mode). (just check, just check-client, just check-server)
  • format: For auto-formatting code. (just format, just format-client, just format-server)
  • test: For running unit, integration, and e2e tests. (just test [server_pattern] [client_pattern] [e2e_pattern], just server-test [pattern], just test-client [pattern], just test-e2e [pattern])
  • db-*: For database migration tasks using sqlx. (just db-setup, just db-migrate, just db-rollback, just db-new-migration <name>)
  • clean: For cleaning build artifacts, dependencies, and temporary files. (just clean, just clean-client, just clean-server)

Creating New Projects from This Template

This template includes a CLI tool for scaffolding new projects:

# Build the template CLI tool
just template-build

# Create a new project interactively
./scripts/create-web-template/target/release/create-web-template new my-project

# Create a project with specific features
./scripts/create-web-template/target/release/create-web-template new my-project \
  --features local_auth,stripe_payment,chat

# Update an existing project with latest template changes
./scripts/create-web-template/target/release/create-web-template update

See the template usage documentation for detailed instructions.

Code Quality and Standards

This project enforces high code quality through several mechanisms:

  • Pre-commit Hooks: Configured in web-template/.pre-commit-config.yaml, these hooks automatically run on every git commit attempt. They perform checks like:

    • Secrets detection (gitleaks).
    • Code formatting (Prettier for client, cargo fmt for server).
    • Linting (ESLint for client, cargo clippy -D warnings -D clippy::pedantic for server).
    • Type checking for Svelte/TypeScript.
    • Ensuring lockfiles (Cargo.lock, bun.lockb) are up-to-date and consistent with Cargo.toml/package.json. If any hook fails, the commit will be aborted, allowing you to fix the issues. You must run pre-commit install once in the repository (from the web-template directory or the repo root if configured project-wide) to enable these hooks.

  • Manual Quality Checks: Use the just check command to run all linters, formatters (in check mode), and type checkers for both client and server.

    • just check-client: Runs all checks for the SvelteKit client.
    • just check-server: Runs all checks for the Rust server. It's good practice to run these before pushing changes, even with pre-commit hooks enabled.

  • Continuous Integration (CI): (To be configured) CI pipelines will eventually run all checks (just check), builds (just build), and tests (just test) automatically on pull requests and merges to the main branch to ensure ongoing quality and stability.
