# Development Setup Guide
2+
3+
This guide helps you set up a local development environment for MetaCPAN Web.
4+
5+
## Quick Setup
6+
7+
For automated setup, run:
8+
9+
```bash
10+
./bin/setup-dev
11+
```
12+
13+
This script will:
14+
- Check system requirements
15+
- Install system dependencies (libcmark-dev)
16+
- Install Perl development tools (carton, cpm)
17+
- Install all project dependencies
18+
- Build static assets
19+
- Set up git hooks
20+
- Run basic tests
21+
22+
## Manual Setup
23+
24+
If you prefer to set up manually or the automated script doesn't work in your environment:
25+
26+
### Prerequisites
27+
28+
- Perl 5.36+ (tested with 5.38.2)
29+
- Node.js 20+ (tested with 20.19.4)
30+
- npm 10+ (tested with 10.8.2)
31+
- System dependencies: libcmark-dev (on Ubuntu/Debian)
32+
33+
### Install Dependencies
34+
35+
1. **Install system dependencies:**
36+
```bash
37+
# On Ubuntu/Debian
38+
sudo apt-get install libcmark-dev
39+
40+
# On macOS
41+
brew install cmark
42+
```
43+
44+
2. **Install Perl tools:**
45+
```bash
46+
# Install carton and cpm
47+
cpan App::carton App::cpm
48+
```
49+
50+
3. **Install Node.js dependencies:**
51+
```bash
52+
npm install
53+
```
54+
55+
4. **Install Perl dependencies:**
56+
```bash
57+
# Using cpm (faster)
58+
cpm install --resolver=snapshot
59+
60+
# Or using carton
61+
carton install
62+
```
63+
64+
5. **Build static assets:**
65+
```bash
66+
npm run build
67+
```
68+
69+
6. **Set up git hooks:**
70+
```bash
71+
./git/setup.sh
72+
```
73+
74+
## Running the Application
75+
76+
### Development Server
77+
78+
```bash
79+
carton exec plackup -p 5001 -r app.psgi
80+
```
81+
82+
The application will be available at http://localhost:5001
83+
84+
### Alternative Servers
85+
86+
For better performance during development:
87+
88+
```bash
89+
# Using Gazelle
90+
carton exec plackup -p 5001 -s Gazelle -r app.psgi
91+
92+
# Using Starman
93+
carton exec plackup -p 5001 -s Starman app.psgi
94+
```
95+
96+
## Testing
97+
98+
### Run All Tests
99+
100+
```bash
101+
carton exec prove -l -r --jobs 2 t
102+
```
103+
104+
### Run Specific Tests
105+
106+
```bash
107+
# Basic functionality tests (work offline)
108+
carton exec prove -l t/moose.t t/assets.t t/session.t
109+
110+
# Specific controller tests
111+
carton exec prove -l t/controller/about.t
112+
```
113+
114+
### Note on Test Failures
115+
116+
Many tests require network access to `api.metacpan.org` and will fail in isolated environments. This is expected behavior. The core functionality tests (like `t/moose.t`, `t/assets.t`, etc.) should pass.
117+
118+
## Asset Development
119+
120+
### Building Assets
121+
122+
```bash
123+
# One-time build
124+
npm run build
125+
126+
# Minified build (for production)
127+
npm run build:min
128+
129+
# Watch for changes during development
130+
npm run build:watch
131+
```
132+
133+
### Asset Files
134+
135+
- Source files: `root/static/`
136+
- Built files: `root/assets/`
137+
- Build configuration: `build-assets.mjs`
138+
139+
## Code Quality
140+
141+
### Linting
142+
143+
The project uses `precious` to orchestrate various linters:
144+
145+
```bash
146+
# Install precious (if not using Docker)
147+
./bin/install-precious /usr/local/bin
148+
149+
# Lint all files
150+
precious lint --all
151+
152+
# Lint specific files
153+
precious lint path/to/file
154+
155+
# Auto-fix issues
156+
precious tidy --all
157+
```
158+
159+
### Git Hooks
160+
161+
Pre-commit hooks are configured to run `precious` automatically. Set them up with:
162+
163+
```bash
164+
./git/setup.sh
165+
```
166+
167+
## Docker Development
168+
169+
For a completely isolated environment, use Docker:
170+
171+
```bash
172+
# Build development image
173+
docker build --target develop -t metacpan-web:dev .
174+
175+
# Run development container
176+
docker run -it -p 5001:8000 -v $(pwd):/app metacpan-web:dev
177+
```
178+
179+
## Configuration
180+
181+
### Local Configuration
182+
183+
Create a `metacpan_web_local.yaml` file to override settings:
184+
185+
```yaml
186+
api: http://127.0.0.1:5000 # Local API server
187+
debug: 1
188+
```
189+
190+
### Environment Variables
191+
192+
- `PLACK_ENV`: Set to `development` for development mode
193+
- `METACPAN_WEB_HOME`: Path to application root (auto-detected)
194+
195+
## Troubleshooting
196+
197+
### Common Issues
198+
199+
1. **Asset map errors**: Run `npm run build` to generate assets
200+
2. **Permission errors**: Check that `local/` directory is writable
201+
3. **Test failures**: Most network-dependent tests will fail without API access
202+
4. **Module not found**: Ensure `carton exec` is used or local lib is in `PERL5LIB`
203+
204+
### Getting Help
205+
206+
- Check the main [README.md](README.md)
207+
- Review existing [issues](https://github.com/metacpan/metacpan-web/issues)
208+
- Ask in the MetaCPAN IRC channel or discussions
