Usage in Typescript

[clabnet]

Hi @meghein,
trying to use @autotelic/fastify-mail 0.8.0 with Fastify 4.26 , Typescript 5.4 and Node 20.11.
I have trouble to pass the correct opts object to fastify.mailer.sendMail method.
I cannot instanciate correctly your package. Can you support me please ?
Here a reproducible project.
Thank you in advance.

Into plugins folder I have this file to register the plugin:

/// <reference path="../global.d.ts" />
import { FastifyInstance, FastifyPluginOptions } from "fastify";
const mail = require("@autotelic/fastify-mail")
const defaults = {
  from: "John Doe <[email protected]>",
  subject: "Hello world",
};
const transport = {
  provider: "mailtrap", // using aws to send email
  pool: true,
  host: "sandbox.smtp.mailtrap.io",
  port: 2525,
  secure: false, // use TLS
  auth: {
    user: "xxxxxxxxxxxxx",
    pass: "yyyyyyyyyyyyy",
  },
};
export default async function (
  fastify: FastifyInstance,
  opts: FastifyPluginOptions
) {
  await fastify.register(mail, { pov: { engine: { nunjucks: require('nunjucks') } }, transporter: transport })
  fastify.log.debug("Registered plugin autotelic-fastify-mail");
}

global.d.ts

import {
  PlatformaticApp,
  PlatformaticServiceConfig,
} from "@platformatic/service";
import { Transporter } from "nodemailer";
export interface FastifyMailerNamedInstance {
  [namespace: string]: Transporter;
}
export type FastifyMailer = FastifyMailerNamedInstance & Transporter;
declare module "fastify" {
  interface FastifyInstance {
    platformatic: PlatformaticApp<PlatformaticServiceConfig>;
    mailer: FastifyMailer;
  }
}

routes\root.ts

/// <reference path="../global.d.ts" />
import { FastifyInstance, FastifyPluginOptions } from "fastify";

import fastifyMail from "@autotelic/fastify-mail";
import Mail from "nodemailer/lib/mailer";

export default async function (
  fastify: FastifyInstance,
  opts: FastifyPluginOptions
) {
  fastify.post("/send-compose", async (request, reply) => {
    const message = {
      to: "[email protected]",
      from: "[email protected]",
      cc: "[email protected]",
      bcc: "[email protected]",
      subject: "This is a subject",
    };

//  ====  ERROR ZONE =====================================
    const opts : Mail.Options = {
      templatePath: "./templates/",
      context: { name: 'Test Name', sender: '[email protected]' }
    };

    const queued = fastify.mailer.sendMail(opts);
// ====  ERROR ZONE END =====================================

    if (queued.error) {
      const { error } = queued;
      reply.send(error);
    } else {
      const { messageId } = queued;
      reply.send({ messageId });
    }
  });
}
