{"id":26347,"library":"rudder-typer","title":"RudderTyper","description":"RudderTyper is a CLI tool (current stable v1.7.5) that generates strongly-typed analytics clients for RudderStack based on your tracking plan spec. It produces compile-time error checking and autocomplete for event names, properties, and types. Supports JavaScript, Node.js, Android, and iOS targets. Key differentiators: natively integrates with RudderStack tracking plans, enables CI validation of instrumentation before deployment, and outputs typed clients that reduce runtime errors. Release cadence is irregular with bug fixes and occasional features. Maintained by RudderStack.","status":"active","version":"1.7.5","language":"javascript","source_language":"en","source_url":"https://github.com/rudderlabs/rudder-typer","tags":["javascript","typescript"],"install":[{"cmd":"npm install rudder-typer","lang":"bash","label":"npm"},{"cmd":"yarn add rudder-typer","lang":"bash","label":"yarn"},{"cmd":"pnpm add rudder-typer","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"RudderTyper is primarily a CLI tool; runtime imports are from the generated client, not this package.
