Node Js Download [UPDATED] Email Attachment
Adele Morss
The first key is the format of the attachment JSON object, which according to the email node info tab must follow the nodemailer format. In this case I only have one attachment, so I provide just one file JSON object that holds the file name and file content, following this basic format template:
The most important things here are that I include the entire file path, and that I return a single buffer object that will then be written to msg.payload and handed in as the attachment content in the next function node.
Note: If you are using gmail, make sure you set up the sending account with an application password. Because of this requirement I recommend using an email account separate from your personal or work email accounts just for Node-RED.
If your file name changes for any reason, or if you regularly add new files and want to email the latest one, you can also take advantage of the fact that the file-in node can use a message property msg.filename to determine which file it will read in.
The two nodes I have pointed out are the two that you need to change the file path to match between Windows, EPIC and RIO.
The file path is used in both of those nodes so just adjust it to suit your platform and so on.
I gave some of the suggestions here a try myself but running code complained that send_mail() and sendMail() is undefined (even though I simply copy & pasted code with minor tweaks). I'm using node 0.12.4 and npm 2.10.1. I had no issues with emailjs, that just worked off the shelf for me. And it has nice wrapper around attachments, so you can attach it various ways to your liking and easily, compared to the nodemailer examples here.
I suggest trying the workflow with two fixed paths and see if it works fine. Then try to aggregate these two and convert the output to variable and pass it to the send mail node. And at last, generate one of them as a flow variable and do the same as I did in the workflow.
To send a text formatted as HTML, no extra attributes are required, just put your HTML body into the message with an html attribute. For advanced templates, you can add attachments and embed images.
To test emails sent with Nodemailer, we will use Mailtrap Email Testing, a tool developers use to test emails in staging without the risk of spamming users. Email Testing allows you to inspect and debug email messages in a safe environment to understand how your application handles email sending, check the content and formatting of the emails via HTML/CSS check feature.
Additionally, you can run a spam analysis of your emails and get a detailed report of spam test points with their descriptions and see whether your IP or domain has been listed on any of the commonly used blacklists.
Additionally, Nodemailer has a NodemailerApp. It provides Sendmail replacement, but first of all, is designed to debug emails. Furthermore, NodemailerApp has a local POP3 and SMTP servers, a catchall email domain service, along with email preview capabilities.
In this example, Mailtrap will catch our message, and demonstrates how it will look in a standard email client. The image will appear embedded with CID into the message body and at the same time it will be shown as an attachment.
This way, you will be able to analyze the email sending process and quickly fix errors, if there are any.
Specify debug options in the transporter section of the mail script in your Node.js app:
In order to send multiple attachments using flow variable you need to have flow variable of type array/collection. This is a older topic which explains it well and contains a workflow example but should be valid still:
So I wanted to add some conditions to at least prevent the really small files to be added, but I'm not sure how to do it. The node don't have any 'conditions' variable and the only other thing I can think of is a onAfter BR.
Unsurprisingly the uuencoded attachments in non-MIME messages have a limited range of characters that can be used in the filename. Basically just plain ASCII (No emoji. Total loser). File naming was much simpler back in the day.
In parallel to RFC2813 another standard was released, RFC2814 that together with the newly defined filename parameter finally fixed the long standing issue of non-latin attachment filenames. This was done by introducing yet another encoding scheme, Parameter Values and Parameter Value Continuations. When encoded-words used equals sign to indicate encoded characters and question mark to separate different parts of the scheme then Parameter Values use percent sign for encoding and single quote for separation.
Do you really have to keep using only latin characters when sending to a chinese service? Fortunately not. QQ webmail does support non-latin characters, including in attachment names, they just do not follow the standards for that.
So what you really need to do in this case would be to add the same filename to attachment headers twice. Once to Content-Disposition, using the standard Parameter Value encoding and once to Content-Type, using encoded-word encoding.
Gmail provides a concept of Less secure apps using which we can use plain password to send emails. Turn on this setting in the link
Instead of directly providing the password, we can also use OAuth2 by adding Oauth token details in the transporter object.
My Scenario is from cXML file to idoc to mail. i.e 1st Mapping: cxML -> ORDERS IDOC, 2nd Mapping: ORDERS idoc- > EMail . I have written java code to attach the idoc as email attachment and add some text in body. IDOC is getting attached and even body is visible in email but the problem in with the content of IDOC. New Line characters "CR LF" are getting added in between Nodes names such as
Likewise CR LF is getting added at some random places.Thus the malformed xml is getting attached in email.I have added code in java mapping to remove CR LF but it is removing all CR LF from File except the one which is in between the Node names.
I have a media video content type that has a video file field (takes a file), name, and air date. The video files are saved on amazon S3 not locally.
I want to monitor the files that are uploaded and get an email (that has the file name, file size, and URL) every time a file of 100MB or more is uploaded even before the node is saved when the user is still on the add/edit form.How can I do that I looked into hook_entity_insert and file_presave or another option?
But I am a bit confused as to which one will be the best and how to implement it.
Adding an email messaging API to your mobile or web app is a necessity as it provides a channel of communication between you and your end-users. Email messages are used for transactional purposes, notifications, advertisement, etc. We are going to build a simple express.js app to demonstrate how you can send email templates and attachments using nodemailer.
We will use Mailjet email delivery SMTP relay service, so you will need to create a Mailjet account. After that go to the developer guide select SMTP relay and you will see a configuration screen like this.
Set up your express app then install multer, nodemailer, dotenv and pug. Create in the root directory for handling our email sending service. Create config.env file and email.js file in the project directory. In the config.env file copy the secrets from the mailjet page and save them as environment variables as shown below.
In email.js we are going to create a class for sending emails using nodemailer. In the constructor will specify the address of the sender which must be in our validated addresses variable. The transporter method will create the nodemailer transport using the secrets obtained from Mailjet.
The send method will send the email message to the recipients. The email message object is configured and passed in data for sending the message to the recipient(s). the email message is sent as a text via the text field or HTML via the HTML field. The send method input argument is an object with the following fields
Use to send HTML or plaintext emails from an external SMTP server. Attachments from the filesystem may also be included. Authentication is supported via workflow or node level credentials and connection security via STARTTLS and SSL are both supported.
The Amazon SES API provides two different ways for you to send an email, depending on how much control you want over the composition of the email message: formatted and raw. For details, see Sending Formatted Email Using the Amazon SES API and Sending Raw Email Using the Amazon SES API.
In this example, you use a series of Node.js modules to send email in a variety of ways. The Node.js modules use the SDK for JavaScript to create and use email templates using these methods of the AWS.SES client class:
If your account is still in the Amazon SES sandbox, you can only send to verified addresses or domains, or to email addresses associated with the Amazon SES Mailbox Simulator. For more information, see Verifying Email Addresses and Domains in the Amazon Simple Email Service Developer Guide.
The message must include at least one recipient email address. The recipient address can be a To: address, a CC: address, or a BCC: address. If a recipient email address is invalid (that is, it is not in the format UserName@[SubDomain.]Domain.TopLevelDomain), the entire message is rejected, even if the message contains other recipients that are valid.
The message cannot include more than 50 recipients, across the To:, CC: and BCC: fields. If you need to send an email message to a larger audience, you can divide your recipient list into groups of 50 or fewer, and then call the sendEmail method several times to send the message to each group.
Create an object to pass the parameter values that define the email to be sent, including sender and receiver addresses, subject, email body in plain text and HTML formats, to the sendEmail method of the AWS.SES client class. To call the sendEmail method, create a promise for invoking an Amazon SES service object, passing the parameters. Then handle the response in the promise callback.
