nestjs-imap

A NestJS module for interacting with IMAP servers using the node-imap package.

Installation

To install the package, run:

npm install nestjs-imap

Configuration

To use the nestjs-imap module, you need to import it into your NestJS module and provide the necessary IMAP configuration.

Example Configuration

import { Module } from '@nestjs/common';
import { ImapModule, ImapConfig } from 'nestjs-imap';

const imapConfig: ImapConfig = {
  user: '[email protected]',
  password: 'your-password',
  host: 'imap.example.com',
  port: 993,
  tls: true,
};

@Module({
  imports: [ImapModule.forRoot(imapConfig)],
})
export class AppModule {}

Usage

You can use the ImapService to interact with your IMAP server. Here's an example of how to use the service:

Example Service

import { Injectable, OnModuleInit } from '@nestjs/common';
import { ImapService } from 'nestjs-imap';

@Injectable()
export class EmailService implements OnModuleInit {
  constructor(private readonly imapService: ImapService) {}

  async onModuleInit() {
    this.imapService.connect();
    this.imapService.on('ready', async () => {
      // Open the mailbox in read-write mode to allow modifying message flags
      await this.imapService.openBox('INBOX', false);
      const messages = await this.imapService.getMessages(['UNSEEN'], {
        bodies: '',
      });

      console.log('Messages:', messages);

      if (messages.length > 0) {
        const message = messages[0];
        const uid = message.attributes.uid;

        console.log('UID:', uid);

        if (uid) {
          try {
            const fullMessage = await this.imapService.readMessage(uid);
            console.log('Full Message:', fullMessage);

            // Mark the message as read
            await this.imapService.markAsRead(uid);
            console.log('Message marked as read');
          } catch (error) {
            console.error('Error:', error);
          }
        } else {
          console.error('Message UID is not valid');
        }
      } else {
        console.log('No new messages');
      }
    });
  }
}
