Fully functional DDEX XML parser for JavaScript and TypeScript with complete data structure access. Built on Rust with native Node.js bindings and WASM browser support - parse DDEX files with full access to releases, resources, deals, and tracks.
## Installation
```bash
npm install ddex-parser
# or for specific version
npm install ddex-parser@0.4.4
# or
yarn add ddex-parser
```
> **⚠️ v0.4.4 Breaking Changes**
> Enhanced validation now properly fails on missing required fields instead of using placeholder values. Ensure your error handling can catch validation errors for incomplete DDEX files.
## Quick Start
### Node.js (ESM/CommonJS)
```javascript
const { DdexParser } = require('ddex-parser');
const fs = require('fs');
const parser = new DdexParser();
const xmlContent = fs.readFileSync('release.xml', 'utf8');
const result = parser.parseSync(xmlContent);
// Full access to parsed data structures
console.log('Message ID:', result.messageId);
console.log('Total Releases:', result.releases.length);
console.log('Total Resources:', Object.keys(result.resources).length);
console.log('Total Deals:', result.deals.length);
// Access individual releases
result.releases.forEach((release, index) => {
console.log(`Release ${index + 1}:`, {
id: release.releaseId,
title: release.title,
artist: release.displayArtist,
trackCount: release.tracks.length
});
});
```
### Error Handling (v0.4.4+)
```javascript
const { DdexParser } = require('ddex-parser');
const parser = new DdexParser();
try {
const result = parser.parseSync(xmlContent);
console.log('Parse successful:', result.messageId);
} catch (error) {
console.error('Parse failed:', error.message);
// v0.4.4+ provides detailed field-specific errors
if (error.message.includes('missing required field')) {
console.log('Incomplete DDEX file - missing required fields');
} else if (error.message.includes('XML parsing failed')) {
console.log('Malformed XML structure');
}
}
```
### Browser (ES Modules)
```typescript
import { DdexParser } from 'ddex-parser/browser';
const parser = new DdexParser();
const result = await parser.parseString(xmlContent);
// Process the parsed data
result.flattened.tracks.forEach(track => {
console.log(`${track.position}. ${track.title} - ${track.duration}s`);
});
```

## API Reference
### DdexParser
```typescript
class DdexParser {
constructor();
// Synchronous parsing with complete data access
parseSync(xml: string, options?: ParseOptions): ParsedMessage;
// Asynchronous parsing with complete data access
parse(xml: string, options?: ParseOptions): Promise<ParsedMessage>;
// Utilities
detectVersion(xml: string): string;
sanityCheck(xml: string): Promise<SanityCheckResult>;
// Streaming (returns async iterator)
stream(xml: string, options?: StreamOptions): ReleaseStream;
}
```
## Comprehensive Usage Examples
### Working with Releases and Tracks
```javascript
const { DdexParser } = require('ddex-parser');
const parser = new DdexParser();
const result = parser.parseSync(xmlContent);
// Access all releases
console.log(`Found ${result.releases.length} releases`);
result.releases.forEach(release => {
console.log(`\nRelease: ${release.title}`);
console.log(`Artist: ${release.displayArtist}`);
console.log(`Type: ${release.releaseType}`);
console.log(`Release Date: ${release.releaseDate}`);
console.log(`Track Count: ${release.tracks.length}`);
// Access individual tracks
release.tracks.forEach((track, index) => {
console.log(` Track ${index + 1}: ${track.title}`);
console.log(` Artist: ${track.artist}`);
console.log(` Duration: ${track.duration}`);
console.log(` ISRC: ${track.isrc}`);
});
});
```
### Working with Resources
```javascript
const parser = new DdexParser();
const result = parser.parseSync(xmlContent);
// Access all resources
const resourceIds = Object.keys(result.resources);
console.log(`Found ${resourceIds.length} resources`);
resourceIds.forEach(resourceId => {
const resource = result.resources[resourceId];
console.log(`\nResource: ${resource.title}`);
console.log(`Type: ${resource.resourceType}`);
console.log(`Duration: ${resource.durationString}`);
console.log(`File Format: ${resource.fileFormat}`);
console.log(`Bitrate: ${resource.bitrate}`);
console.log(`Sample Rate: ${resource.sampleRate}`);
});
```
### Working with Deals
```javascript
const parser = new DdexParser();
const result = parser.parseSync(xmlContent);
// Access all deals
console.log(`Found ${result.deals.length} deals`);
result.deals.forEach(deal => {
console.log(`\nDeal: ${deal.dealId}`);
console.log(`Releases: ${deal.releases.join(', ')}`);
console.log(`Territories: ${deal.territories.join(', ')}`);
console.log(`Start Date: ${deal.startDate}`);
console.log(`End Date: ${deal.endDate}`);
console.log(`Commercial Model: ${deal.commercialModel}`);
console.log(`Usage Rights: ${deal.usageRights.join(', ')}`);
});
```
### Async Parsing
```javascript
const parser = new DdexParser();
try {
const result = await parser.parse(xmlContent);
console.log('Successfully parsed:', {
messageId: result.messageId,
releases: result.releases.length,
resources: Object.keys(result.resources).length,
deals: result.deals.length
});
} catch (error) {
console.error('Parse failed:', error.message);
}
```
### Version Detection and Validation
```javascript
const parser = new DdexParser();
// Detect DDEX version
const version = parser.detectVersion(xmlContent);
console.log('DDEX Version:', version); // e.g., "V4_3"
// Comprehensive validation
const sanityResult = await parser.sanityCheck(xmlContent);
if (sanityResult.isValid) {
console.log(`Valid DDEX ${sanityResult.version}`);
} else {
console.log('Validation errors:', sanityResult.errors);
console.log('Warnings:', sanityResult.warnings);
}
```
