Safely Convert Query Parameters in NestJS

When developing APIs, you might run into issues with query parameter types, especially when handling pagination number or some boolean values, since query parameters are always strings. In this video, I'll show you two ways to convert query parameters to the correct types in NestJS. We'll first explore enabling implicit conversion in the global Validation Pipe, and then switch to a safer method using the Type decorator from class-transformer for explicit type conversion. This approach ensures proper type handling for numbers, booleans, and more, without risking unexpected future issues.
