To retrieve an attachment that has been added to a document in PouchDB, you can use the
getAttachment() method. This method allows you to fetch the attachment content associated with a specific document and attachment ID. Here's how you can retrieve an attachment in PouchDB :
// Assuming 'db' is your PouchDB instance and 'docId' is the ID of the document
// and 'attachmentId' is the ID of the attachment you want to retrieve
db.getAttachment(docId, attachmentId).then(function(blob) {
// 'blob' is the attachment content retrieved as a Blob object
// You can use this blob to manipulate or display the attachment content as needed
}).catch(function(err) {
console.log('Error retrieving attachment:', err);
});?
In the above code :* Replace '
db' with your PouchDB instance.
* Replace '
docId' with the ID of the document that contains the attachment.
* Replace '
attachmentId' with the ID of the attachment you want to retrieve.
* The
getAttachment() method returns a Promise that resolves with a Blob object containing the attachment content. You can then use this Blob object to manipulate or display the attachment content in your application as needed.
If the attachment retrieval encounters an error (e.g., if the document or attachment does not exist), the Promise will be rejected, and you can handle the error accordingly in the
catch() block.
This approach allows you to retrieve attachments added to documents in PouchDB and integrate them into your application as needed.
