# emailjs [![Test Status](https://github.com/eleith/emailjs/workflows/.github/workflows/test.yml/badge.svg)](https://github.com/eleith/emailjs/actions?query=workflow%3A.github%2Fworkflows%2Ftest.yml) [![Lint Status](https://github.com/eleith/emailjs/workflows/.github/workflows/lint.yml/badge.svg)](https://github.com/eleith/emailjs/actions?query=workflow%3A.github%2Fworkflows%2Flint.yml) send emails, html and attachments (files, streams and strings) from node.js to any smtp server ## INSTALLING npm install emailjs ## FEATURES - works with SSL and TLS smtp servers - supports smtp authentication ('PLAIN', 'LOGIN', 'CRAM-MD5', 'XOAUTH2') - emails are queued and the queue is sent asynchronously - supports sending html emails and emails with multiple attachments (MIME) - attachments can be added as strings, streams or file paths - supports utf-8 headers and body - built-in type declarations - automatically handles [greylisting](http://projects.puremagic.com/greylisting/whitepaper.html) ## REQUIRES - auth access to an SMTP Server - if your service (ex: gmail) uses two-step authentication, use an application specific password ## EXAMPLE USAGE - text only emails ```js import { SMTPClient } from 'emailjs'; const client = new SMTPClient({ user: 'user', password: 'password', host: 'smtp.your-email.com', ssl: true, }); // send the message and get a callback with an error or details of the message that was sent client.send( { text: 'i hope this works', from: 'you ', to: 'someone , another ', cc: 'else ', subject: 'testing emailjs', }, (err, message) => { console.log(err || message); } ); ``` ## EXAMPLE USAGE - using async/await ```js // assuming top-level await for brevity import { SMTPClient } from 'emailjs'; const client = new SMTPClient({ user: 'user', password: 'password', host: 'smtp.your-email.com', ssl: true, }); try { const message = await client.sendAsync({ text: 'i hope this works', from: 'you ', to: 'someone , another ', cc: 'else ', subject: 'testing emailjs', }); console.log(message); } catch (err) { console.error(err); } ``` ## EXAMPLE USAGE - html emails and attachments ```js import { SMTPClient } from 'emailjs'; const client = new SMTPClient({ user: 'user', password: 'password', host: 'smtp.your-email.com', ssl: true, }); const message = { text: 'i hope this works', from: 'you ', to: 'someone , another ', cc: 'else ', subject: 'testing emailjs', attachment: [ { data: 'i hope this works!', alternative: true }, { path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' }, ], }; // send the message and get a callback with an error or details of the message that was sent client.send(message, function (err, message) { console.log(err || message); }); // you can continue to send more messages with successive calls to 'client.send', // they will be queued on the same smtp connection // or instead of using the built-in client you can create an instance of 'smtp.SMTPConnection' ``` ## EXAMPLE USAGE - sending through outlook ```js import { SMTPClient, Message } from 'emailjs'; const client = new SMTPClient({ user: 'user', password: 'password', host: 'smtp-mail.outlook.com', tls: { ciphers: 'SSLv3', }, }); const message = new Message({ text: 'i hope this works', from: 'you ', to: 'someone , another ', cc: 'else ', subject: 'testing emailjs', attachment: [ { data: 'i hope this works!', alternative: true }, { path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' }, ], }); // send the message and get a callback with an error or details of the message that was sent client.send(message, (err, message) => { console.log(err || message); }); ``` ## EXAMPLE USAGE - attaching and embedding an image ```js import { SMTPClient, Message } from 'emailjs'; const client = new SMTPClient({ user: 'user', password: 'password', host: 'smtp-mail.outlook.com', tls: { ciphers: 'SSLv3', }, }); const message = new Message({ text: 'i hope this works', from: 'you ', to: 'someone , another ', cc: 'else ', subject: 'testing emailjs', attachment: [ { data: 'i hope this works! here is an image:

', }, { path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' }, { path: 'path/to/image.jpg', type: 'image/jpg', headers: { 'Content-ID': '' }, }, ], }); // send the message and get a callback with an error or details of the message that was sent client.send(message, (err, message) => { console.log(err || message); }); ``` # API ## new SMTPClient(options) ```js // options is an object with the following recognized schema: const options = { user, // username for logging into smtp password, // password for logging into smtp host, // smtp host (defaults to 'localhost') port, // smtp port (defaults to 25 for unencrypted, 465 for `ssl`, and 587 for `tls`) ssl, // boolean or object (if true or object, ssl connection will be made) tls, // boolean or object (if true or object, starttls will be initiated) timeout, // max number of milliseconds to wait for smtp responses (defaults to 5000) domain, // domain to greet smtp with (defaults to os.hostname) authentication, // array of preferred authentication methods ('PLAIN', 'LOGIN', 'CRAM-MD5', 'XOAUTH2') logger, // override the built-in logger (useful for e.g. Azure Function Apps, where console.log doesn't work) }; // ssl/tls objects are an abbreviated form of [`tls.connect`](https://nodejs.org/dist/latest-v14.x/docs/api/tls.html#tls_tls_connect_options_callback)'s options // the missing items are: `port`, `host`, `path`, `socket`, `timeout` and `secureContext` // NOTE: `host` is trimmed before being used to establish a connection; // however, the original untrimmed value will still be visible in configuration. ``` ## SMTPClient#send(message, callback) ```js // message can be a smtp.Message (as returned by email.message.create) // or an object identical to the first argument accepted by email.message.create // callback will be executed with (err, message) // either when message is sent or an error has occurred ``` ## new Message(headers) ```js // headers is an object with the following recognized schema: const headers = { from, // sender of the format (address or name

or "name"

) to, // recipients (same format as above), multiple recipients are separated by a comma cc, // carbon copied recipients (same format as above) bcc, // blind carbon copied recipients (same format as above) text, // text of the email subject, // string subject of the email attachment, // one attachment or array of attachments }; // the `from` field is required. // at least one `to`, `cc`, or `bcc` header is also required. // you can also add whatever other headers you want. ``` ## Message#attach(options) Can be called multiple times, each adding a new attachment. ```js // options is an object with the following recognized schema: const options = { // one of these fields is required path, // string to where the file is located data, // string of the data you want to attach stream, // binary stream that will provide attachment data (make sure it is in the paused state) // better performance for binary streams is achieved if buffer.length % (76*6) == 0 // current max size of buffer must be no larger than Message.BUFFERSIZE // optionally these fields are also accepted type, // string of the file mime type name, // name to give the file as perceived by the recipient charset, // charset to encode attatchment in method, // method to send attachment as (used by calendar invites) alternative, // if true, will be attached inline as an alternative (also defaults type='text/html') inline, // if true, will be attached inline encoded, // set this to true if the data is already base64 encoded, (avoid this if possible) headers, // object containing header=>value pairs for inclusion in this attachment's header related, // an array of attachments that you want to be related to the parent attachment }; ``` ## Message#checkValidity() Synchronously validate that a Message is properly formed. ```js const message = new Message(options); const { isValid, validationError } = message.checkValidity(); if (isValid) { // ... } else { // first error encountered console.error(validationError); } ``` ## new SMTPConnection(options={}) ```js // options is an object with the following recognized schema: const options = { user, // username for logging into smtp password, // password for logging into smtp host, // smtp host (defaults to 'localhost') port, // smtp port (defaults to 25 for unencrypted, 465 for `ssl`, and 587 for `tls`) ssl, // boolean or object (if true or object, ssl connection will be made) tls, // boolean or object (if true or object, starttls will be initiated) timeout, // max number of milliseconds to wait for smtp responses (defaults to 5000) domain, // domain to greet smtp with (defaults to os.hostname) authentication, // array of preferred authentication methods ('PLAIN', 'LOGIN', 'CRAM-MD5', 'XOAUTH2') logger, // override the built-in logger (useful for e.g. Azure Function Apps, where console.log doesn't work) }; // ssl/tls objects are an abbreviated form of [`tls.connect`](https://nodejs.org/dist/latest-v14.x/docs/api/tls.html#tls_tls_connect_options_callback)'s options // the missing items are: `port`, `host`, `path`, `socket`, `timeout` and `secureContext` // NOTE: `host` is trimmed before being used to establish a connection; // however, the original untrimmed value will still be visible in configuration. ``` To target a Message Transfer Agent (MTA), omit all options. ## SMTPConnection#authentication associative array of currently supported SMTP authentication mechanisms ## Authors eleith zackschuster ## Testing npm install -d npm test ## Contributions issues and pull requests are welcome
