What is the Final Plugin Package?

A BrainDrive plugin is distributed as a ZIP file that users can install via the Plugin Installer UI.

ZIP File Naming

Format

{plugin-slug}-{version}.zip

Examples

✅ VALID
- my-plugin-1.0.0.zip
- task-manager-0.1.0.zip
- data-dashboard-2.3.1.zip

❌ INVALID
- my-plugin.zip (missing version)
- my-plugin-v1.0.0.zip (has "v" prefix)
- my-plugin-latest.zip (not semver)
- my_plugin-1.0.0.zip (uses underscore)

Build Output Requirements

MUST Include: dist/ Folder

Before creating the ZIP, run the build:

npm install
npm run build

This creates the

dist/

folder with:

• dist/remoteEntry.js (REQUIRED) - Module Federation entry point
• dist/main.js - Your plugin code bundle
• dist/{other-chunks}.js - Split code chunks if any

MUST Exist Before ZIP

# Verify dist folder and remoteEntry.js exist
ls -la dist/
# Output:
# -rw-r--r--  main.js
# -rw-r--r--  remoteEntry.js

Build Configuration (webpack.config.js)

const { ModuleFederationPlugin } = require('webpack').container;

module.exports = {
  mode: 'production',
  entry: './src/index.tsx',
  output: {
    path: __dirname + '/dist',
    filename: 'main.js',
    publicPath: 'auto'  // Critical for Module Federation
  },
  
  plugins: [
    new ModuleFederationPlugin({
      name: 'MyPlugin',              // Must match plugin_slug
      filename: 'remoteEntry.js',   // MUST be exactly this
      exposes: {
        './index': './src/index.tsx'
      },
      shared: {
        react: { singleton: true, requiredVersion: '^18.2.0' },
        'react-dom': { singleton: true, requiredVersion: '^18.2.0' }
      }
    })
  ]
};

Step-by-Step Packaging Process

Step 1: Verify Source Code

# Check that all source files exist
ls -la
# Files MUST exist:
# - package.json
# - lifecycle_manager.py
# - webpack.config.js
# - tsconfig.json
# - src/index.tsx

Step 2: Install Dependencies

npm install

Step 3: Build for Production

npm run build

Verify build output:

ls -la dist/
# Must show:
# remoteEntry.js
# main.js

Step 4: Verify dist/ Folder Size

du -sh dist/
# Typical plugin: 100KB - 500KB
# If > 2MB: check for large dependencies or assets

Step 5: Create ZIP File

Using command line:

# Option 1: Include dist/
zip -r my-plugin-1.0.0.zip my-plugin/

# Option 2: Manual folder structure
mkdir package_dir
cp -r my-plugin/* package_dir/
cd package_dir
zip -r ../my-plugin-1.0.0.zip .
cd ..
rm -rf package_dir

Using Node.js:

const archiver = require('archiver');
const fs = require('fs');

const output = fs.createWriteStream('my-plugin-1.0.0.zip');
const archive = archiver('zip', { zlib: { level: 9 } });

output.on('close', () => {
  console.log('ZIP created:', archive.pointer() + ' total bytes');
});

archive.pipe(output);
archive.directory('my-plugin/', 'my-plugin');
archive.finalize();

Step 6: Verify ZIP Contents

# List ZIP contents
unzip -l my-plugin-1.0.0.zip

# Should show structure like:
# my-plugin-1.0.0/my-plugin/package.json
# my-plugin-1.0.0/my-plugin/lifecycle_manager.py
# my-plugin-1.0.0/my-plugin/dist/remoteEntry.js
# ... etc

Step 7: Store ZIP

• For distribution: Upload to plugin marketplace
• For installation: Keep ZIP file available locally
• For backup: Store with version tag

What NOT to Include in ZIP

❌ Exclude These:

• node_modules/

  (too large, users will run npm install)

• .git/

  (version control files)

• .gitignore

• .env

  (sensitive data)

• src/

  (source code, not needed for runtime)

• *.log

  (log files)

• .DS_Store

  (macOS metadata)

• Thumbs.db

  (Windows metadata)

• dist/

  if it's pre-built (users may build differently)

❌ Actually, reconsider

dist/

:

• Pro: Users don't need to build, faster install
• Con: Large ZIP, platform-specific build artifacts
• Recommendation: Include

  dist/

  for end users, exclude for developers

.npmignore or Similar

If you want different files for npm publishing vs plugin distribution, create

.npmignore

:

# .npmignore
dist/
node_modules/
.git
.env
*.log
screenshot/
docs/

Installation Instructions (Include in README.md)

## Installation

1. Download the plugin ZIP file
2. Open BrainDrive
3. Go to Settings → Plugins → Install Plugin
4. Select the ZIP file
5. BrainDrive will install the plugin and reload
6. Plugin appears in the sidebar / main menu

## Building from Source

If you have the source code:

```bash
npm install
npm run build
zip -r my-plugin-1.0.0.zip my-plugin/

Then follow installation steps above.

## Validation Before Packaging

Run this checklist:

```bash
# ✅ Verify essential files exist
[ -f package.json ] && echo "✓ package.json"
[ -f lifecycle_manager.py ] && echo "✓ lifecycle_manager.py"
[ -f webpack.config.js ] && echo "✓ webpack.config.js"
[ -f tsconfig.json ] && echo "✓ tsconfig.json"
[ -d src ] && echo "✓ src/ folder"
[ -d dist ] && echo "✓ dist/ folder"
[ -f dist/remoteEntry.js ] && echo "✓ dist/remoteEntry.js"

# ✅ Verify version consistency
echo "package.json version:"
grep '"version"' package.json

echo "lifecycle_manager.py version:"
grep '"version"' lifecycle_manager.py

# ✅ Verify plugin_slug matches scope
echo "plugin_slug:"
grep 'plugin_slug' lifecycle_manager.py

echo "webpack scope:"
grep "name: '" webpack.config.js

# ✅ Verify no sensitive data
! grep -r 'API_KEY\|SECRET\|PASSWORD' src/ && echo "✓ No hardcoded secrets"
! [ -f .env ] && echo "✓ No .env file"

ZIP Size Guidelines

Size	Status	Recommendation
< 100 KB	✅ Excellent	Small, fast download
100 KB - 500 KB	✅ Good	Typical for feature-rich plugins
500 KB - 2 MB	⚠️ Large	Consider optimizing dependencies
> 2 MB	❌ Too Large	Likely includes unnecessary files

Optimization Tips

If your ZIP is too large:

1. Remove node_modules before zipping:

   rm -rf node_modules/
   zip -r my-plugin-1.0.0.zip my-plugin/
   

2. Exclude src/ if dist/ exists:

   zip -r my-plugin-1.0.0.zip my-plugin/ -x "my-plugin/src/*"
   

3. Minimize dependencies:

   # Remove unused packages
   npm prune --production
   

4. Check for large assets:

   find dist/ -size +100k
   

Common Packaging Mistakes

❌ Missing dist/remoteEntry.js

# Forgot to build!
npm run build  # Fix this first

❌ Version mismatch

# package.json: 1.0.0
# lifecycle_manager.py: 1.0.1
# ZIP name: my-plugin-1.0.2.zip
# FIX: Make all three match!

❌ Wrong scope in webpack

// plugin_slug: "MyPlugin"
// webpack scope: "DifferentScope"  // WRONG!

❌ Including node_modules

# This makes ZIP huge!
# Always exclude node_modules

Re-Packaging for Updates

When releasing a new version:

1. Update version in package.json, lifecycle_manager.py, changelog
2. Rebuild:

   npm run build

3. Create new ZIP:

   {slug}-{new-version}.zip

4. Keep old ZIP for version history
5. Update plugin manifest/changelog

Packaging is the final step. Get it right, and users can install your plugin with a single click.
