building-nango-functions-locally

You can develop Nango functions locally by building and validating actions or syncs in a checked-out Zero YAML TypeScript project, requiring index.ts registration, dryrun validation, and generated tests before deploying.

The Zero YAML approach enables building and iterating on Nango actions or syncs entirely offline using real-world TypeScript files and a registered index.ts entry point, enforcing local development best practices like dryrun validation and test generation.

Yes, running a Nango dryrun requires local file registration through an index.ts entry point in your checked-out Zero YAML TypeScript project to validate functions and generate tests properly.

Yes, you can validate Nango syncs and actions entirely offline by using the local dryrun workflow to test with real-world files and generate tests before pushing to the remote environment.

Building Nango functions locally requires a checked-out Zero YAML TypeScript project and enforces strict best practices: you must register files in index.ts, pass dryrun validation, and generate tests before optionally deploying actions or syncs.
