Here’s a detailed development plan for a Rust + Tauri-based UXCL Browser (uxcl-browser), focused on delivering a solid MVP and a clean long-term path. It covers architecture, scope, milestones, and concrete tasks you can hand to a small team.
|
||||
|
||||
Goals, scope, and success criteria
|
||||
MVP scope (first 12 weeks, adjustable):
|
||||
A Rust core that implements UCXL protocol interactions (parsing UCXL URIs, envelope operations like GET/PUT/POST/ANNOUNCE/DELETE, basic envelope history/store).
|
||||
A Tauri-based UI shell with a web frontend (React or Svelte) that talks to the Rust core via a secure IPC bridge.
|
||||
Core UI screens: Dashboard (overview), Envelope Viewer (JSON/details), Action Toolbar (GET/PUT/POST/ANNOUNCE/DELETE), and Logs/Console.
|
||||
Local storage for envelopes/history (in-memory with optional on-disk persistence for MVP).
|
||||
Linux-native look-and-feel with decent cross-distro packaging support (AppImage and Flatpak).
|
||||
Basic security posture: sandboxed UI, strict IPC surface, input validation, CSP.
|
||||
Non-goals for MVP:
|
||||
Cross-platform parity in visuals beyond Linux initially (Windows/macOS can come later).
|
||||
Advanced encryption or hardware security modules in MVP (focus on solid core and secure IPC first).
|
||||
Success metrics:
|
||||
Buildable AppImage/Flatpak artefacts for Pop!_OS within 12 weeks.
|
||||
Sub-1-second IPC latency for typical UCXL commands in a dev machine.
|
||||
Positive developer feedback on code structure and testability.
|
||||
Passes a basic security hygiene review (no untrusted code paths, input validation, minimal privileges).
|
||||
Reference architecture
|
||||
Core rust crate (uxcl-core)
|
||||
Responsibilities: UCXL URI parsing, envelope data models, envelope operations (GET/PUT/POST/ANNOUNCE/DELETE), in-memory envelope store, simple transport layer (mock or real UCXI interactions), async runtime.
|
||||
Public API example (high level):
|
||||
UCxlEnvelope, UCxlCommand (enum of GET/PUT/POST/ANNOUNCE/DELETE), UCxlResult
|
||||
Async functions: execute_command(cmd, params) -> Result<Response, UCxlError>
|
||||
EnvelopeStore trait with CRUD methods
|
||||
UI layer (Tauri app)
|
||||
Frontend: Single-page app (SPA) built with React or Svelte, TypeScript.
|
||||
IPC: Define a small, versioned set of commands sent from UI to Rust core, with strict input/output schemas (e.g., UiToCoreCommand and CoreToUiResponse).
|
||||
UI panels:
|
||||
Address bar for UCXL URIs
|
||||
Envelope list/history panel
|
||||
Envelope detail viewer (formatted JSON and raw)
|
||||
Action bar for GET/PUT/POST/ANNOUNCE/DELETE
|
||||
Logs panel
|
||||
Security: Tauri sandbox, content security policy, only permit necessary APIs; frontend code isolated from direct filesystem/network access.
|
||||
Data flow
|
||||
UI issues commands via IPC to uxcl-core
|
||||
Core performs the operation and responds with structured data
|
||||
UI renders results and appends to logs
|
||||
Packaging and deployment
|
||||
Linux-first packaging: AppImage and Flatpak (target Pop!_OS), with optional Debian packaging later
|
||||
CI builds for Linux, with artifact publishing
|
||||
Tech stack decisions
|
||||
Core: Rust (stable, safe, fast)
|
||||
Async runtime: Tokio (or async-std if you prefer; Tokio is more common and robust)
|
||||
Data formats: serde with serde_json for envelope payloads
|
||||
Networking/IO: reqwest or hyper for any local/remote UCXI endpoints
|
||||
Persistence: in-memory store initially; optional on-disk store via sled or a simple JSON store
|
||||
UI: Tauri with a React or Svelte frontend
|
||||
Web framework: React (with Vite) or SvelteKit
|
||||
Styling: CSS variables, lib/adwaita color tokens if you want a GNOME-like look
|
||||
Build and packaging
|
||||
Rust toolchain (rustup), cargo workspaces
|
||||
Tauri CLI for building the native app
|
||||
AppImage and Flatpak for Linux packaging
|
||||
Testing
|
||||
Unit tests in Rust for core logic
|
||||
Integration tests for IPC surface
|
||||
UI end-to-end tests (optional; can start with Playwright or Cypress in a later phase)
|
||||

Risks and mitigations
|

Risk: UCXL core complexity grows beyond simple in-memory store
|
||||
Mitigation: design core with clean interfaces and allow swapping in a database or mock UCXI transport later
|
||||
Risk: UI/IPC surface grows too large
|
||||
Mitigation: lock scope to essential MVP commands; add additional commands only when needed
|
||||
Risk: Linux packaging headaches
|
||||
Mitigation: rely on established tooling (Tauri bundling, Flatpak) and keep packaging logic modular
|
||||
Risk: Security validation gaps
|
||||
Mitigation: implement strict input validation, CSP, sandboxed UI, code reviews focused on IPC
|
||||
Roles and responsibilities (small team)
|
||||
Product/UX Lead: define UX flow, wireframes, and acceptance criteria
|
||||
Rust Core Developer: implement ucxl-core, data models, IPC surface, tests
|
||||
Frontend Developer: build SPA, integrate with IPC, ensure good UX
|
||||
DevOps/CI Engineer: set up CI, packaging pipelines, automated tests
|
||||
QA/Security Reviewer: review security posture, run basic tests, ensure compliance
|
||||
Next steps (immediate actions)
|
||||
Create the monorepo structure with uxcl-core and uxcl-tauri-app
|
||||
Set up initial CI workflow (Linux build and tests)
|
||||
Create a minimal UCXL core with URI parsing and a simple envelope struct
|
||||
Generate the Tauri app scaffold and wire it to call a sample core function
|
||||
Define the IPC contract: UiToCoreCommand, CoreToUiResponse, with a couple of initial commands (e.g., GET envelope)
|
||||
Prepare wireframes and design tokens for the UI
