Contributing to Pulse
Thanks for investing time in Pulse! This document collects the essentials you need to be productive across the Go backend, SolidJS/TypeScript frontend, and the installer tooling.
Project Overview
- Backend (
cmd/,internal/,pkg/) – Go 1.25+ web server that embeds the built frontend and exposes REST + WebSocket APIs. - Architecture (
ARCHITECTURE.md) – High-level system design diagrams and explanations. - Frontend (
frontend-modern/) – Vite + SolidJS app built with TypeScript. - Agents (
cmd/pulse-*-agent) – Go binaries distributed alongside Pulse for host and Docker telemetry. - Documentation (
docs/) – Markdown-based guides published to users and referenced from the README. - Scripts (
scripts/) – Bash installers and helpers bundled for curl-based distribution.
Getting Started
git clone https://github.com/rcourtman/Pulse.git
cd Pulse
# Install dependencies
brew install go node npm # or use your distro equivalents
# Install JS deps
cd frontend-modern
npm install
cd ..
Hot Reload Dev Loop
npm run dev # Frontend shell on :5173, backend on :7655
npm run mock:on # Optional: enable mock data
Use http://127.0.0.1:5173 in the browser for local frontend development. The
frontend dev shell proxies /api and /ws to the backend on :7655; do not
switch your browser to :7655 unless you are debugging the backend directly.
Backend-only hot reload (requires air):
air -c .air.toml
Set HOT_DEV_USE_PRO=true to build the Pro variant when available.
Mock mode is supported for development, but the internal developer notes are not shipped in this repository.
Backend Workflow
- Build:
go build ./cmd/pulse - Tests:
go test ./... - Lint:
golangci-lint run ./...(install viago installif missing) - Formatting:
gofmt -w ./cmd ./internal ./pkg
Key entry points:
- HTTP router lives in
internal/api. - Monitoring engines live under
internal/monitor. - Configuration parsing resides in
internal/config.
When adding new API endpoints, document them in docs/API.md and provide
examples where possible.
Frontend Workflow
- Managed dev runtime:
npm run dev - Runtime status:
npm run dev:status - Runtime logs:
npm run dev:logs - Managed restart:
npm run dev:restart - Managed backend restart:
npm run dev:backend-restart - Browser proof pack:
npm run dev:verify - Foreground managed launcher:
npm run dev:foreground - Frontend-only escape hatch:
cd frontend-modern && npm run dev:frontend-only - Tests:
npm run test - Lint:
npm run lint - Format:
npm run format
The same managed runtime wrappers are available from frontend-modern/ if you
start there by habit, so npm run dev, npm run dev:status, and
npm run dev:verify behave the same way from either workspace.
- Production build:
npm run build(syncs the Go embed copy ininternal/api/frontend-modern/distautomatically).
Use SolidJS patterns (signals, memos, createEffect) and the shared design-system
components in components/shared/. Add screenshots when introducing new
UI-heavy features.
Design-system lint rules are enforced as CI blockers. Avoid hardcoded structural
light/dark classes and broken utility chains; use semantic tokens from
frontend-modern/DESIGN_SYSTEM.md.
Installers & Scripts
- Centralised guidance:
docs/internal/SCRIPT_LIBRARY.md - Bundling:
make bundle-scripts - Tests:
scripts/tests/run.shplus integration suites underscripts/tests/integration/
Document rollout plans and kill switches in MIGRATION_SCAFFOLDING.md so future contributors know how to disable risky changes.
Documentation Standards
- Author or update guides in
docs/when behaviour changes. - Organise new topics through
docs/README.mdso they appear in the docs index. - Avoid marketing copy in technical docs—save that for
README.mdor external sites. - Keep instructions evergreen; put release-specific notes in
docs/RELEASE_NOTES.md.
Run a quick link check (npm run lint-docs if available, or markdownlint)
before submitting large doc updates.
Testing Expectations
- Every PR should note the tests run (
go test,npm test,scripts/tests/run.sh). - Add regression coverage when fixing bugs.
- Mention manual verification steps (e.g., “Proxmox LXC installer tested on PVE 8.1”) if automated coverage is not feasible.
Coding Guidelines
- Adhere to existing formatting tools (
gofmt,prettier,eslint). - Name Go packages with short, meaningful identifiers (avoid
util). - Keep functions focused; prefer small helpers over large monoliths.
- Prefer context-aware logging (
logger.Named("component")) in new Go code. - Ensure secrets never reach logs and redact sensitive fields in API responses.
Submitting Changes
- Fork + branch (
git checkout -b feature/my-change). - Make your edits and run relevant tests.
- Update docs and changelog entries as needed.
- Open a PR describing:
- What changed
- Why it changed
- Testing performed
- Rollout / migration concerns
Reviewers will focus on correctness, security, and upgrade paths, so call out anything unusual up front. Thanks again for contributing!
