How to works?

jin-curlize create curl command from FastifyRequest. URL, querystirng, header create using IncomingMessage in FastifyRequest. For example,

• IncomingMessage.IncomingHttpHeaders to --header option
• IncomingMessage.url to querystring and href

But IncomingMessage is already ended ReadableStream in FastifyReqest. So body create using FastifyRequest.body.

Usage

create curl command

import fastify from 'fastify';
import { createFromFastify3 } from 'jin-curlize';

const server = fastify({
  logger: {
    transport: {
      target: 'pino-pretty',
    },
    serializers: {
      res(reply) {
        return {

          parameters: request.params,
          headers: request.headers,
          axios: JSON.stringify(createAxiosFromFastify3(request)),
        };
