What's Inside
- Project Structure (Why It Matters for Types)
- TypeScript + tsconfig Setup (Jest Reporter Specific)
- Type Definition Exports (package.json typings, exports fields)
- Creating Your First Reporter Class (Typed Examples)
- Publishing to npm with Correct Type Entrypoint
Your package.json needs this exact configuration: ``` { "name": "jest-reporter-yourname", "version": "1.0.0", "main": "./lib/index.js", "types": "./lib/index.d.ts", "exports": { ".": { "import": "./lib/index.js", "require": "./lib/index.js", "types": "./lib/index.d.ts" } }, "files": ["lib"], "devDependencies": { "@types/jest": "^29.0.0", "jest": "^29.0.0", "typescript": "^5.0.0" } } ``` main:./lib/index.js is the entry point. Types:./lib/index.d.ts tells TypeScript where your definitions live. Without both, consuming projects won't find your types.
