Attachments are a way to send and receive files with in emails.
Sending attachments
Send attachments using the compose page in the dashboard or by using the sendEmail
methods with a list of attachment IDs. Attachment IDs can be created by uploading files before sending (see next section). Here is an example using the NodeJS client:
await mailslurp.sendEmail(inbox.id!, {
to: [inbox.emailAddress!],
subject: 'attachment test',
attachments: [attachmentId.toString()],
});
Uploading attachments
To upload attachments use the upload attachment method and pass a base64 encoded string for the file content. An array containing an attachment ID will be returned. Use the attachment ID to send the attachment or download it.
// notice that an array with one attachment id is returned
const [attachmentId] = await mailslurp.uploadAttachment({
base64Contents: Buffer.from('hello').toString('base64'),
contentType: 'text/plain',
filename: 'test.txt',
});
Downloading attachments
Here is how to download files found on an email object.
const attachment =
await mailslurp.attachmentController.downloadAttachmentAsBase64Encoded({
attachmentId: email.attachments?.[0]!,
});
const content = new Buffer(
attachment.base64FileContents!,
'base64'
).toString('utf8');
expect(content).toEqual('hello');
