Fastify Fastest Validator

This plugin provides a simple way to validate incoming requests using the fastest-validator library.

Installation

pnpm install fastify-fastest-validator

Usage

import fastify from 'fastify';
import fastifyFastestValidator from 'fastify-fastest-validator';

const app = fastify();

app.register(fastifyFastestValidator, {
  validatorOptions: {
    // fastest-validator options
  },
});

app.get('/hello', {
  validationConfig: {
    querySchema: {
      name: { type: 'string' },
    },
  },
}, async (request, reply) => {
  return `Hello, ${request.query.name}!`;
});

The sample code above demonstrates how to use the fastify-fastest-validator plugin to validate incoming requests. The validationConfig object is used to specify the schema for validating the request parameters. If any validation errors occur, a 400 Bad Request response is returned with an array of error messages.

The plugin accepts the following options:

• validatorOptions: Options to pass to the fastest-validator constructor.
