What are all the built-in pipes NestJS ships with?

0-2 years experience

1. 1You need to ensure that a route parameter `id` is parsed as an integer before it reaches the controller method. Which built‑in pipe would you use and how would you apply it?
2. 2If you add the `ParseBoolPipe` to a query parameter expecting a boolean, what happens when the client sends the string `'yes'`? How does Nest handle the conversion or error?

1. 1Your team added `ValidationPipe` globally, but a new endpoint that accepts a file upload is now failing validation unexpectedly. Walk me through how you would debug the issue and decide whether to keep the global pipe or override it.
2. 2When using `ParseIntPipe` on a DTO property, you notice that certain large numbers are being truncated. Explain why this occurs and what alternative built‑in pipe or configuration you could use to handle big integers.

1. 1In a high‑traffic microservice we need to validate incoming JSON payloads without sacrificing latency. How would you evaluate the performance impact of the built‑in `ValidationPipe` versus a custom lightweight pipe, and what trade‑offs would you consider?
2. 2Our monorepo contains dozens of NestJS services, each using different combinations of built‑in pipes. Describe a strategy to standardize pipe usage across services while allowing service‑specific overrides, and how you’d enforce it.

8+ years experience

1. 1We are migrating a legacy codebase that manually parses and validates request data to NestJS. How would you design a migration plan that leverages the built‑in pipes to improve consistency, and what risks or edge cases would you watch for during the rollout?
2. 2As the architecture lead, you need to define a policy for when to use Nest’s built‑in pipes versus custom pipes across the organization. What criteria would you set, and how would you balance developer productivity, security, and maintainability?
