Project Architecture

This project follows the atomic design pattern. Components are organized by complexity, not by feature.

Design Hierarchy

Level	Purpose	Example
Atoms	Single-purpose UI elements	Button, Input, Text, Badge
Molecules	Groups of atoms working together	Card, FormField
Organisms	Complex UI sections	Header, DonationForm, ProjectGrid
Templates	Page-level structural layouts	DashboardLayout, AuthLayout

Stellar Color Tokens

These brand colors are defined in app/globals.css and available as Tailwind classes:

Token	Value	Tailwind Class
Stellar Blue	#14B6E7	bg-stellar-blue, text-stellar-blue
Stellar Purple	#3E1BDB	bg-stellar-purple, text-stellar-purple
Stellar Navy	#0D0B21	bg-stellar-navy, text-stellar-navy
Stellar Cyan	#00C2FF	bg-stellar-cyan, text-stellar-cyan
Stellar Green	#00B36B	bg-stellar-green, text-stellar-green

Import Convention

No barrel exports. Always import directly from the component file:

// Correct
import { Button } from "@/components/atoms/Button";
import { Card, CardHeader } from "@/components/molecules/Card";

// Wrong — do not use index.ts barrel exports
import { Button } from "@/components/atoms";

Contributing

1. Pick an Issue

Browse open issues labeled Stellar Wave. Comment on the issue to claim it. Do not work on an issue someone else has claimed without coordinating.

2. Branch from main

Always start from the latest main:

git checkout main
git pull origin main
git checkout -b feat/<issue-number>-<short-description>

Branch naming examples:

• feat/42-wallet-connect-modal
• fix/78-rate-limit-toast
• docs/107-contributing-guide

3. Coding Standards

• TypeScript strict mode — no any, no unused variables
• Component patterns — use forwardRef where needed, always set displayName, export named types
• Naming — PascalCase for components, camelCase for functions/variables, kebab-case for CSS classes
• Atomic design — atoms extend ui/ base components with Stellar variants; molecules compose atoms
• No barrel exports — import directly from the file, not from index.ts

4. Commit Conventions

This project enforces Conventional Commits and atomic commits.

Commit Message Format

<type>(<scope>): <short description>

[optional body]

[optional footer]

Allowed Types

Type	When to use
feat	New feature or component
fix	Bug fix
docs	Documentation only
style	Formatting, no logic change
refactor	Code restructuring, no behavior change
perf	Performance improvement
test	Adding or updating tests
build	Build system or dependency changes
ci	CI configuration changes
chore	Maintenance tasks

Allowed Scopes

auth, wallet, dashboard, marketplace, admin, donation, carbon, ui, layout, nav, config, deps

Examples

feat(wallet): add Stellar wallet connection modal
fix(donation): correct minimum amount validation
docs(contributing): add commit convention section
style(ui): format Button component with Prettier
refactor(dashboard): extract tab components into separate files

Atomic Commit Rules

1. One concern per commit — never mix a bug fix with a new feature
2. Each commit must build — pnpm build must pass at every single commit
3. Each commit must be revertable — reverting one commit must not break unrelated code
4. Order matters — foundation first, then features, then polish

Bad example (one giant commit):

feat: add dashboard with tabs, fix header bug, update colors

Good example (atomic):

feat(dashboard): create dashboard page layout
feat(dashboard): add overview tab component
feat(dashboard): add donations tab component
fix(nav): correct active link highlighting on dashboard
style(dashboard): align tab content padding

5. Pull Request Process

Before Submitting

# Make sure you're up to date with main
git checkout main
git pull origin main
git checkout <your-branch>
git rebase main

# Verify everything passes
pnpm build
pnpm lint

PR Requirements

Every PR must include:

• Linked issue — use Closes #<issue-number> in the PR description
• Screen recording — record your implementation working in the browser and attach it to the PR
• Filled PR template — Summary, What Was Implemented, Implementation Details, How to Test
• Passing CI — build and lint must pass

PRs without a screen recording or without a linked issue will not be reviewed.

PR Template

When you open a PR, the template will auto-populate. Fill out every section:

## Summary
<!-- 1-3 sentences: What does this PR do and why? -->

## Related Issue
Closes #<issue-number>

## What Was Implemented
<!-- Detailed list of what was built/changed -->
- [ ] Component X created
- [ ] Styling applied with Stellar tokens
- [ ] Responsive on mobile

## Implementation Details
<!-- Key decisions, patterns used, trade-offs -->

## Screenshots / Recordings
<!-- REQUIRED: Screen recording of your implementation -->

## How to Test
<!-- Step-by-step for reviewers -->
1. Checkout this branch
2. Run `pnpm dev`
3. Navigate to /path
4. Verify X works

6. Code Review

• Expect feedback. Reviews are about improving the code, not criticizing the author.
• Respond to every comment — either make the change or explain why not.
• After addressing feedback, re-request review.
• Maintainers will merge once approved and CI passes.

7. Stay in Sync

While your PR is in review, keep your branch up to date:

git checkout main
git pull origin main
git checkout <your-branch>
git rebase main
git push --force-with-lease
